Getting Started

recommended that you leave an empty space (1U) above and below

In this section, you will learn how to:

• Install the Binloop

• Play a test clip

Installation

These instructions assume that you have received your Binloop from Alcorn McBride with the Controller card and the appropriate reproducers already installed. For detailed instructions and information on installing the Binloop see the Installation Guidelines section later in this manual.

Unpacking Instructions

When you unpack this product you may want to consider holding on to the original packing material for shipment to the installation site, or in case you need to return it to the factory for repair or exchange.

PLEASE DON’T THROW AWAY THIS MANUAL!

Installation Instructions

Note: It is always ideal to use power protection such as surge protection and/or an uninterruptible power supply to ensure a reliable power source for the Binloop.

The Binloop is designed to be installed in an equipment rack. It is

the unit for free-air circulation, and install it in a climate-controlled room. Failure to do so could result in damage or intermittent operation of the Binloop.

1. Place the Binloop in the appropriate position on the rack.

2. Insert screws into the rack-mounting holes on both sides of the unit and tighten.

3. Connect the power plug to an appropriate outlet.

4. The Binloop will operate with 100-240VAC, 6-3A Max. 60-50 Hz.

5. Connect the audio/video cables from the Reproducer outputs to the A/V equipment (i.e. displays, amplifiers, etc.)

Alcorn McBride Binloop User’s Manual Page 3

Playing a Test File

Preparation

Now it’s time to put that nice shiny new Binloop to work and make it play some media. The Binloop is commonly used to either play video or audio, so this section provides information on playing both types of media. Be sure to follow the instructions that are more suitable for your Binloop application.

Before you can play media on the Binloop, you need to load the audio or video content onto a Compact Flash card. To do this, you’ll need the following items:

1. Compact Flash card

2. Compact Flash card reader

3. Test Media File (Video or Audio)

Compact Flash Card

If you did not purchase Compact Flash cards with your Binloop, we highly recommend you purchase SanDisk® brand cards. There are many different Compact Flash devices out there with different specs and compatibility issues. We recommend SanDisk® cards because we can guarantee that they work in all of our Compact Flash products. Also, it’s important to mention that Compact Flash cards come in a variety of capacities. To help you select a size that suits your needs, be sure to read over Appendix B: Compact Flash Media

Capacities.

Compact Flash Card Reader

The Compact Flash card reader is required to interface the Compact Flash device with your PC. The most common card reader connects to your PC using USB. These are widely available in consumer electronics stores, and can also be purchased from Alcorn McBride.

Binloop Test Files

The Binloop test files can be downloaded from the product support pages on our website. Please download either the Audio of Video test clip. Here are the support page links:

Formatting the Compact Flash

While holding the Test Button, insert the Compact Flash card into the

All Compact Flash Sockets have ejector buttons that make it easier to insert and remove the flash media.

When you insert a flash card, do so with the manufacturer’s label to the right. The card should insert easily and require very little force to fully seat.

Loading the Test File

Once you have the necessary materials, you are ready to get started. First, it is recommended that you format the Compact Flash card in the Binloop. This can be accomplished by following these instructions:

With the Compact Flash card removed, power up the Binloop using the power switch on the back of the unit.

Press and hold the Test Button of channel #1. You may see the Reproducer indicate a fault (flashing red LED), but this is normal.

Compact Flash socket of channel #1. Wait a second or two for the status LED to turn orange to indicate that the card is being formatted.

When the status LED turns off, the formatting is complete. You may now remove the card.

Now that the Compact Flash has been properly formatted, we’re ready to load the Binloop Test file onto the card. Here’s what you do:

1. Insert the Compact Flash card into the Compact Flash card reader.

2. Connect the card reader to you PC. If the card reader is working properly, the Compact Flash card will show up as an additional drive (i.e. Drive F:) in your computer.

3. Copy and Paste the Binloop Video or Audio Test File to the flash card.

4. If you are loading the test video clip, verify that the name of the test clip is VID00001.MPG. If you are loading the test audio clip, verify that the name of the test clip is SND00001.WAV.

Alcorn McBride Binloop User’s Manual Page 5

Playing the Test File

All of your hard work is about to pay off. Follow these step-by-step instructions to play the test file in the Binloop.

1. If you are playing the video test clip, connect a display to one of the A/V outputs of channel #1 (YPbPr, RGB, or Composite).

2. Insert the Flash card that is loaded with the Binloop audio or video test clip into the Compact Flash socket of channel #1.

3. Power-up the Binloop.

4. Wait for the Binloop to finish initializing. You can determine this by watching status display and the ‘READY’ status LED.

5. Press the channel #1 test button. The channel #1 status LED should turn green to indicate that the clip is playing.

At this point, channel #1 should be outputting video and/or audio on the rear-panel connectors, and this should be apparent on you’re A/V equipment. If it is not, please consult the Troubleshooting Guide for help.

About the Binloop

What is the Binloop?

Put simply, the Binloop is a solid-state multi-channel video and audio player that provides up to 16 separate channels of standard-definition video or 32 channels of uncompressed audio. These channels can be played together synchronously or independently from one another. For stand-alone applications, the Binloop can be configured to play files automatically based on a programmable timeline. For more complex applications, this product can be controlled externally by SMPTE/EBU timecode, MIDI, RS-232, Ethernet or contact closures.

That being said, the Binloop is not your everyday multi-channel media player. Its ability to provide synchronous playback, impeccable precision, and a variety of easy-to-use control interfaces requires unique system architecture. The purpose of this section is to familiarize you with how the Binloop works so that you can gain a better understanding of how best to use it to meet your goals.

What’s inside the Binloop?

The Alcorn McBride Binloop consists of four main types of components –

1. Card Cage

2. Controller Card

3. Reproducer Card(s)

4. CobraNet Card (optional)

Alcorn McBride Binloop User’s Manual Page 7

The Card Cage

The Reproducer slots and CobraNet slot may or may not be populated depending on how your Binloop was ordered.

The Controller Card

The Card Cage is the ‘skeleton’ that integrates the components of the Binloop. This cage contains a Power Supply, a status display, a Controller card slot, and 16 Reproducer card slots. The Reproducer card slots are numbered from 1 to 16, from left to right as viewed from the front of the Binloop.

The back of the Card Cage contains all of the connectors for the Binloop control interfaces, as well as Audio/Video outputs for all 16 Reproducer card slots.

The Controller Card is responsible for the core functionality of the Binloop. This card updates the Status Display with information and provides front-panel buttons for controlling basic Binloop functions. It also handles all external communication from the remote control interfaces of the Binloop, as well as internal communication with the Reproducer cards. In addition, it provides the Binloop with the ability to either Generate or Read SMPTE timecode. It also has the ability to store a list of SMPTE triggers that can be precisely executed at specified times. To maintain synchronization between Binloop components, this card also supplies all audio and video sync signals to the Reproducer cards.

The Reproducer Cards

The main function of each Reproducer is to play video files from a removable Compact Flash card. During playback, the video and audio output generated by the reproducer is available on the connectors found on the back of the Binloop cage. Each reproducer has output connectors for YPbPr/RGB Component Video, Unbalanced Audio, Balanced Audio, and Digital Audio (AES/EBU or S/PDIF).

The reproducer cards receive all playback commands (i.e. Play, Stop, Pause, etc.) from the controller card. To ensure perfect synchronization, the reproducers share common Video and Audio clocks that are supplied by the controller card as well.

The video files themselves can be encoded using one of several popular video and audio codecs that are supported by the reproducers. For more specific information regarding the type of media content that the reproducer cards can play, refer to the chapter that covers Media Files.

Alcorn McBride Binloop User’s Manual Page 8

The CobraNet Card

CobraNet is a common industry standard for distributing audio over an Ethernet-based network. When a Binloop is equipped with the CobraNet option, you can distribute the stereo audio outputs of up to 16 reproducers (that’s 32 channels of audio) over a CobraNet network. When this option is installed, an additional RJ-45 Ethernet jack is located on the back of the Binloop cage. For more information about CobraNet, including how to configure and use this feature, refer to the CobraNet section of this manual.

Alcorn McBride Binloop User’s Manual Page 9

How the Binloop Works

Now that you’re more familiar with the various hardware components that comprise the Binloop, let’s get more familiar with how those components actually work together. The diagram below outlines the different components we’ve covered as well as their functional relationship with one another.

The sections that follow will cover the various systems you see in this diagram, so please use it as a visual reference.

Alcorn McBride Binloop User’s Manual Page 10

Control System

The Control system of the controller card is the heart of the Binloop. This system handles all of the Binloop’s control interfaces. In addition, the Control system is responsible for configuring and controlling both the SMPTE Interface and the A/V Sync system that also reside on the controller card. This system’s final significant role is to configure and control the reproducers over a shared communications line.

Control Interfaces

The Control system monitors all of the control interfaces, which include Ethernet, Parallel, RS-232, MIDI, and the Front Panel interface. Anything that happens on these interfaces, in one way or another, is translated by the Control system into a command to do something.

For example, the Control system may receive an RS-232 command to play video 1 on reproducer 1. It must interpret this command, and then send the appropriate control signal to the reproducer to make it happen. Another common example would be using the Parallel control port to start the SMPTE generator. The Control system would sense a contact closure on the Parallel control port, and then instruct the SMPTE Interface to start generating timecode.

You can read more about these control interfaces, and how they work in a later chapter in this manual titled Controlling the Binloop.

Reproducer Control

Without the Control system, the reproducers would do nothing except generate black video and waste electricity. They have no knowledge of the SMPTE clock value, RS-232 commands, Parallel input status, or anything of the sort. They are simply designed to obey basic playback commands and, in that regard, the Control system is their boss. It is responsible for issuing configuration and playback commands to the reproducers, and is capable of doing so with tremendous precision.

Alcorn McBride Binloop User’s Manual Page 11

A/V Sync System

tus LED on the front of the Binloop will illuminate.

The A/V Sync system plays a critical role in the operations of the Binloop. This system is responsible for generating the Audio and Video clocks used throughout the Binloop. Most notably, these clocks are used directly by the reproducers to ensure that the video and audio outputs are precisely synchronized with one another.

Configuration Options

This system has a few straight-forward, yet important, configuration settings. The first of these settings, Video Format, configures the type of video clocks to generate. There are only two options that cover the primary video systems used throughout the world; NTSC and PAL. The other setting is the audio sample rate, which determines how to generate the audio clocks. Here’s a table that shows the settings that are available to you.

Setting Options

The A/V Sync system always generates the A/V clocks regardless of whether or not an external sync source is present.

Video Format

Sample Rate

These settings can be configured using the Menu Wheel interface on the front of the Binloop, as well as the Binloop Configuration software.

NTSC, PAL

32kHz, 44.1kHz, 48kHz, 96kHz

External V-Sync

If you refer to the diagram earlier in this section, you will see that the A/V Sync system allows for an optional external video sync source. When a supported sync source is connected to V-Sync input of the Binloop, the A/V clocks are locked directly to the source.

This input is designed to accept a Blackburst video sync signal. When the A/V Sync system is successfully locked on to an external sync input, the V-Sync sta Keep in mind that the Video Format setting of the A/V Sync system must match the video format of the Blackburst sync source. If it does not, the A/V Sync system will not attempt to lock to the source.

Alcorn McBride Binloop User’s Manual Page 12

SMPTE Interface

The SMPTE Interface is what gives the Binloop the ability to generate and read SMPTE and EBU timecode. Whether it is generating or reading, this interface provides the Control system with the current SMPTE time. The most important purpose for this is to execute precisely timed user-programmed commands, or triggers, to the reproducer cards. In addition, it provides a SMPTE Frame Clock which is used throughout the Binloop for synchronization purposes.

Configuration Options

The SMPTE Interface is a very powerful and flexible system and, as a result, it has a variety of configurable settings. Here is a summary of those settings:

Setting Description

SMPTE Mode

Framerate

Preroll Time

Start Time

End Time

Loop Mode

Powerup Mode

Restart Mode

Idle Mode

Self-Gen Mode

Determines whether the SMPTE Interface will generate timecode, or read external timecode.

The framerate in which SMPTE is generated.

The initial time of SMPTE generator when it is first enabled.

The time that the SMPTE generator returns to after it reaches the End Time (when looping)

The time when the SMPTE generator either stops or loops back to the Start Time.

Determines whether the SMPTE generator loops continuously from Start to End Time.

Determines whether SMPTE is Enabled or Disabled when the Binloop powers up.

Determines how the SMPTE generator responds when it is told to start again. It can either restart or ignore the start command.

Determines if the SMPTE Output is muted or active when the SMPTE Interface is idle.

Determines how long the SMPTE reader will free-wheel when external SMPTE is lost.

Output Level

These settings can all be configured using the Menu Wheel interface on the front of the Binloop, or with through the Binloop Config software. Please read on to learn more about these settings and how they can be used to configure the SMPTE Interface to meet your needs.

Alcorn McBride Binloop User’s Manual Page 13

Configures the voltage level (in dB) of the SMPTE output.

SMPTE Mode

There are 3 basic modes that the SMPTE Interface can operate in. It can be configured to Read timecode, Generate timecode, or generate timecode in reference to the Binloop’s video clocks (Generate /w V- Sync).

In Read mode, the SMPTE module will listen for incoming timecode on the Binloop’s SMPTE In connector whenever the SMPTE module is enabled. While operating in this mode, the SMPTE Interface will repeat the incoming timecode on the SMPTE Out connector.

In Generate mode, the SMPTE Interface will generate timecode when it is enabled (or started). This timecode is used internally, and is also generated on the SMPTE Out connector.

The Generate /W V-Sync mode operates exactly like the normal Generate mode, except that the SMPTE clock is generated synchronously with the vertical sync video signal of the Binloop. For example, if the Binloop’s A/V Sync system is configured for NTSC (29.97fps), the SMPTE module can generate 29.97fps timecode that is perfectly synchronous. This means that each ‘tick’ of the SMPTE clock will coincide with the beginning of each video frame, even after a long period of time. This feature is useful when you want the SMPTE clock to remain in perfect sync with a video presentation, or with an external video sync source.

SMPTE Times

The Preroll, Start, and End times are all used by the SMPTE Interface when it is programmed to generate timecode. This graphic demonstrates how these times are used by the generator.

As you can see, the timecode starts running from the Preroll Time when the SMPTE Interface is first enabled. The timecode then continues to run until the End Time is reached. What happens at this point depends on the next setting; Loop Mode.

Loop Mode

The Loop mode setting determines what the timecode generator does when the End Time is encountered. If the SMPTE module is configured to loop, the timecode jumps back to the Start Time. If loop mode is disabled, the timecode stops running.

Alcorn McBride Binloop User’s Manual Page 14

Powerup Mode

The Powerup setting simply tells the SMPTE Interface whether or not to start running when the Binloop first turns on. When the Binloop is configured to start on powerup, the SMPTE Interface will begin generating/reading timecode as soon as the system is ‘ready’ (this is indicated by both the ‘ready’ output and ‘ready’ unit status LED).

Restart Mode

The Start SMPTE Command can come from any of the Binloop’s control interfaces, including Parallel, RS-232, Ethernet, MIDI, or the frontpanel.

If external SMPTE drops out, the SMPTE reader will automatically re-lock when it is restored. The Self-Gen Mode simply determines what to do in the meantime.

The Restart Mode setting only applies when the SMPTE Interface is configured to generate timecode. This setting determines how the generation process is affected if a ‘Start SMPTE’ command occurs when timecode is currently running. If the Restart Mode is enabled, another Start command causes the timecode to jump back to the Start Time. If the Restart Mode is disabled, any start commands received while the timecode is running will be completely ignored.

Idle Mode

The Idle Mode determines the state of the SMPTE Output when the SMPTE Interface is Stopped. If the Idle Mode is configured to mute SMPTE, the SMPTE output will be silent when the SMPTE clock is stopped. If the Idle Mode is configured for SMPTE to be active, the SMPTE Output will continuously repeat the timecode value where the clock stopped running on the SMPTE Output.

Self-Gen Mode

This setting applies only when the SMPTE Interface is configured to Read external timecode. It determines how the SMPTE reader should react in the event that the external SMPTE signal drops out, or is lost completely. When this occurs, the SMPTE reader has the ability to continue generating (free-wheel) SMPTE on its own. This allows the Binloop to ‘get by’ until the external SMPTE clock is restored. If you want to implement this feature, this setting can configure the SMPTE Reader to self-generate timecode for a period of 1-8 seconds, or indefinitely. If you don’t want to use this feature, Self-Gen mode can be disabled completely so that the timecode within the Binloop always represents the timecode coming in on the SMPTE Input.

Controlling the Binloop

To ensure that the Binloop can meet the needs of almost any application, it has been designed with several different control interfaces. These interfaces include:

1. Serial (RS-232)

2. MIDI

3. Ethernet

4. Parallel

5. Timecode

Serial Control (RS-232)

The Binloop provides a dedicated Show Control RS-232 port to allow external RS-232 devices to control the product. For added flexibility, this port can be configured to use a variety of serial protocols. Here’s a table that outlines the differences between these protocols:

Protocol Baud Rate Description

Alcorn 9-bit

AMI/Pioneer

MIDI

Debug

Once you determine which protocol is best for your system, you must configure the Show Control port for one of these 4 protocols. This can be done using the front-panel Menu Wheel, or by downloading a configuration from the Binloop Configuration software. When you are ready to control the Binloop, you must connect a NULL RS-232 cable between the controlling device and the Binloop’s Show Control port. Once you have done this, read on to the Control Protocols section of this manual to obtain the full list of commands you can send to the Binloop.

9600 For use with Alcorn Show

Controllers.

9600 Generic ASCII-based protocol

intended for use by almost any serial control device.

38400 For use with MIDI Show Control

systems.

38400 Debug output only. Not used for

control.

Alcorn McBride Binloop User’s Manual Page 17

MIDI Control

Ethernet Control

The Binloop has a dedicated MIDI port for use with MIDI-based control systems. This port operates at the MIDI standard baud rate of 31250. Any MIDI command that is received is repeated on to the MIDI OUT connector.

Refer to the Control Protocols section of this manual for the complete list of MIDI Show Control commands that are supported by the Binloop.

For Ethernet control, the Binloop uses a standard Ethernet Protocol called UDP (User Datagram Protocol).

UDP is a very simple Ethernet protocol that allows an Ethernet device to transmit a generic string of data to another Ethernet device. Since UDP is such a broad standard, UDP packets can be generated by a large variety of controllers and PC applications. The UDP packet handles all of the complexities of getting the message where it needs to go in one piece. The good news is that you do not have to understand those complexities. As a matter of fact, you only need to know the following information to send a UDP message.

Destination IP Address – This needs to be the IP address of the Binloop you intend to control. The default IP address of the Binloop is

192.168.0.254.

Destination Port – This value needs to be the UDP port that the Binloop is listening to for UDP commands. This value is always 2638.

Source Port - This is the UDP port that your PC or controller will use to

send the UDP message. It does not matter what port you choose, as long as it is a valid UDP port. If you have no idea what a valid UDP port is, just use 2638.

Data – This is the actual message that you are sending to the Binloop. This message needs to be an AMI/Pioneer Protocol command. (i.e. 1R1PL<CR>).

Since the UDP commands use the AMI/Pioneer Protocol, they are ASCII based and are terminated with a carriage return (hexadecimal value 0x0D). The complete list of supported commands can be found in the

AMI/Pioneer Protocol section of this manual.

Parallel Control

Parallel Inputs

The Binloop’s Parallel Control interface is designed to provide a very basic control from simple voltage and contact closure inputs. This interface also has 3 dry-contact relay outputs and 2 TTL level outputs that indicate the status of the Binloop. All of these signals are available on the DB-37 Parallel Control connector located on the back of the Binloop.

The following table lists the available inputs of the Binloop’s Parallel control interface, as well as description of their functions:

SMPTE

Video Sync

The Binloop has contact-closure inputs on the rear panel that can be used to command groups of Reproducers to Play or Stop. When used on their own, these 8 ‘Play Group’ inputs cause the associated group to play and loop the associate file. For example, activating the ‘Play Group 2’ input will cause all reproducers assigned to group 2 to play and loop file #2. Activating ‘Play Group 4’ will cause all members of group 4 to play and loop file #4.

There are some additional inputs that can be used in conjunction with the ‘Play Group’ inputs to change their behavior. These include the ‘Stop Group’ input and the ‘Loop Inhibit’ input. As the name implies, activating the ‘Stop Group’ input simultaneously with one of the ‘Play Group’ inputs will cause that group to stop (instead of play and loop). Activating the ‘Loop Inhibit’ input simultaneously with a ‘Play Group’ input causes the associated file to play through once (instead of loop indefinitely).

Alcorn McBride Binloop User’s Manual Page 20

Using the Start SMPTE Input

Please refer to the Hardware section of this manual for pin assignments and other electrical details for the Parallel Control connector.

Using the Mute Input

The Parallel Control connector also contains inputs for starting or stopping the SMPTE Interface. Unlike the Group Control inputs, the SMPTE Control inputs are Opto-Isolated and require a voltage (24V) to be input to them from an external source.

The way to start playback using the SMPTE Control inputs is to configure the Binloop to generate SMPTE, program a playback trigger in the SMPTE Trigger Table and start SMPTE using the Start SMPTE input. When the timecode reaches the programmed trigger time, playback begins.

Single Reproducers, Groups of Reproducers, or All Reproducers can be triggered. It’s all in how you program the trigger.

The Parallel Control connector also contains an input that can Mute the audio output on all of the Reproducers. This input mimics the behavior of the front panel mute button. When this input is active, all reproducer audio outputs are muted. The audio will remain muted until this input is released.

Alcorn McBride Binloop User’s Manual Page 21

Timecode Control

In this method of control, the commands are pre-programmed ahead of time using the Binloop Configuration software, and then downloaded and stored in the Binloop.

The concept is pretty simple. When you program the commands, you must specify a SMPTE timecode value for that command. If the SMPTE clock ever equals that timecode value, the command (or trigger) is executed. This concept applies whether the SMPTE is being read from an external source, or generated internally by the Binloop.

There are several benefits to using this control interface. First, this interface allows the Binloop to operate completely on its own. For example, you could program the Binloop to automatically generate SMPTE timecode when it powers-up. You could then create a ‘Play’ command that gets triggered by the timecode shortly after it starts running. The result is that the Binloop automatically starts playing after power-up with no external control required!

The other benefit to this interface is precision. Each command’s SMPTE execution time is accurate down to the frame. For example, you could make a video start playing at exactly 01:02:05.21. Again, it doesn’t matter if that timecode is being read from an external source or generated internally. This precision also helps with tweaking the playback timing. Is the video starting a little too soon? Just add 1 or 2 frames to the SMPTE execution time to make it start a little later.

For more information about using this method of control, please refer to the Binloop Configuration Software section of this manual. If you would like to configure the Binloop to automatically play upon power up, please see the Application Notes section of this manual.

Alcorn McBride Binloop User’s Manual Page 22

Control Protocols

AMI/Pioneer Control Protocol

For specific information about the RS-232 and Ethernet interfaces, refer to the Controlling the Binloop section of this manual.

This protocol inherits its name from the fact that it closely resembles the popular Pioneer protocol used throughout the A/V industry.

The AMI/Pioneer protocol commands listed in this section are available for use on both the RS-232 Show Control port and the Ethernet port of the Binloop. This section discusses the most commonly used commands in detail.

The protocol is ASCII-based. Upper or lower case characters can be used interchangeably. All commands and responses are terminated

with the Carriage Return character. This character is represented by the hexadecimal value 0x0D.

Search Clip

Description: This command causes the Binloop to preload the specified clip. If it is a video

clip, the reproducer(s) will pause on the first frame of the video. After this happens, the next Play command causes the clip to start playing.

Command: nnnnaaaSE

Parameters: nnnn is an ASCII file number between 0-1023 aaa is the address of the card(s) you want to process the command Rxx – Reproducer address between R1-R16 Gxx – Group address between G1-G13 * - Wildcard address for all reproducers

Response: R

Examples: Search File 1 on Reproducer #2: 1R2SE Search File 2 on Group #1: 2G1SE Search File 52 on All Reproducers: 52*SE

Play / Resume

Description: This command will start playing a clip that was previously loaded by a Search

Clip command. This command will also resume playback when the reproducer has been stilled or paused.

Command: aaaPL

Parameters: aaa is the address of the card(s) you want to process the command Rxx – Reproducer address between R1-R16 Gxx – Group address between G1-G13 * - Wildcard address for all reproducers

Response: R

Example: Search File 1 on Reproducer #2: 1R2SE Play pre-searched file R2PL

Loop / Resume

Description: This command functions just like the Play / Resume command except that the

video loops once the end of the clip is reached.

Command: aaaLP

Parameters: aaa is the address of the card(s) you want to process the command Rxx – Reproducer address between R1-R16 Gxx – Group address between G1-G13 * - Wildcard address for all reproducers

Response: R

Example: Search File 1 on Reproducer #2: 1R2SE Loop pre-searched file: R2LP

Alcorn McBride Binloop User’s Manual Page 33

Play Clip

Description: This command will play the specified clip on the addressed reproducer card(s).

Playback starts as soon as possible after the command is received.

Command: nnnnaaaPL

Response: R

Comments: Since playback starts as quickly as possible once this command is received, it

should never be used for synchronous playback. For this, you should use the Synchronous Play command for a consistent synchronized start of playback. Using a Search command along with a timed Play/Resume command works well for synchronous playback too.

Examples: Play File 3 on Reproducer #1: 3R1PL Play File 4 on Group #2: 4G2PL Play File 52 on All Reproducers: 52*PL

Play/Loop Clip

Description: This command functions exactly like the Play Clip command, except that the

video loops once the end of the clip is reached.

Command: nnnnaaaLP

Response: R

Examples: Loop File 3 on Reproducer #1: 3R1LP Loop File 4 on Group #2: 4G2LP Loop File 52 on All Reproducers: 52*LP

Alcorn McBride Binloop User’s Manual Page 34

Synchronously Play Clip

Description: This command functions exactly like the Play Clip command, except that the

playback does not begin as quickly as possible. Instead, the reproducer waits a consistent amount of time (16 frames by default) after the command is received before it starts playback. This ensures that all reproducers that receive this command at the same time, start playing at the same time.

Command: nnnnaaaSP

Response: R

Comments: This command is almost always addressed to either a Group or All reproducers

to ensure that they all start playing synchronously.

Examples: Synchronously Play File 2 on Group 1: 2G1SP Synchronously Play File 2 on All Reproducers: 2*SP

Synchronously Play/Loop Clip

Description: This command functions like the Synchronously Play Clip command, except that

the clip loops once the end of the clip is reached.

Command: nnnnaaaSL

Response: R

Examples: Synchronously Loop File 2 on Group 1: 2G1SL Synchronously Loop File 2 on All Reproducers: 2*SL

Comments: If you plan to synchronously loop files on multiple reproducers, the clips MUST

be identical in length. If it’s a video, they must be identical down to the frame. If it’s audio, they must be identical down to the sample. If they are not, the clips will not remain in sync after the loop point.

Alcorn McBride Binloop User’s Manual Page 35

Play Next

Description: This command causes the specified file to be "queued" for playback at the

completion of the current clip. If a file is currently playing, the queued transition to the selected file will be seamless. If a file is currently looping, the seamless transition will occur at the next loop point. If a clip is not currently playing, the clip specified in this command will begin playing immediately.

Command: nnnnaaaPN

Response: R

Example: Play File #2 on Reproducer 1: 2R1PL

Queue File #3 to play after file #2 finishes: 3R1PN

Loop Next

Description: This command functions exactly like the Play Next command except that the

queued file loops after it finishes playing.

Command: nnnnaaaLN

Response: R

Example: Play File #2 on Reproducer 1: 2R1PL

Queue File #3 to loop after file #2 finishes: 3R1LN

Alcorn McBride Binloop User’s Manual Page 36

Stop Playback

Description: This command will stop currently playing clip. If a video was playing, the last

frame that was displayed will remain on screen.

MIDI Show Control Protocol

The MIDI Show Control protocol is primarily used when controlling the Binloop over its dedicated MIDI port. However, it is also available as one of the configurable protocols available on the RS-232 Show Control port. If your intention is to control the Binloop with a non-MIDI based system, you should consider using the Pioneer/AMI protocol instead.

It should be noted that MIDI Show Control is a very wide-ranging protocol used for many different applications. Most of the protocol information is beyond the scope of this manual since it is not critical to controlling the Binloop.

General Structure

MIDI Show Control uses a single Universal Real Time System Exclusive ID number (sub-ID #1 = 02H) for all Show commands (transmissions from Controller to Controlled Device). In this version of MIDI Show Control, command responses (from Controlled Devices to Controller) are specified in order to optimize bandwidth requirements, system response time and system reliability in the event of communication difficulties with one or more Controlled Devices. The guiding philosophy behind live performance control is that, as much as possible, failures of individual Controlled Devices should not impair communications with other Controlled Devices. This concept has been a part of MIDI system design from the beginning and MIDI Show Control continues to use an "openloop" design in order that standard MIDI practices may continue to be successfully utilized in applications using all types of standard Channel and system messages.

Using the MIDI Show Control protocol, the Binloop can play clips numbered from 1 to 511 (i.e. VID00001.MPG to VID00511.MPG). These files can either be played from the beginning and stop at the end, or they can be commanded to play and loop at the end. Looping files play continuously, seamlessly starting over at the beginning from the end, until commanded to stop. To cause a video file to loop, you must add 512 to the clip number used in the command. Clip numbers 1 through 511 will be interpreted as non-looping by default, while 513 through 999 are looping. For example, to play clip 1 once you would send a 1 as the clip number in the MIDI show control command. To play and loop clip 1, you would use a clip number of 513 in the MIDI command (even though the actual file number is still 1 on the reproducers flash card).

Since the clip number field is only 3 digits, the maximum file number supported by the MIDI protocol is 999. That means that you can only send a loop command for clips 1-487 (999-512=487).

Binloop Configuration Software

Introduction to the Binloop Software

The Binloop Configuration Software is a Windows application that provides an easy-to-use interface for programming and configuring the Binloop. While it’s true that most of the Binloop’s configuration settings can be accessed from the front-panel Menu Wheel interface, the Binloop application provides a more visual alternative for configuring these settings. In addition, this software is necessary to program SMPTE timecode triggers for applications where you want the Binloop to operate without any external control system.

Requirements

The Binloop software requires that you have PC running Microsoft Windows XP or Windows Vista. This PC must have either an Ethernet port and/or an RS-232 Serial port so that it may communicate with the Binloop.

Installing the Binloop Software

This software can be installed directly from the CD/USB drive that was packaged with the Binloop. If you have Internet access, we recommend downloading the latest version from the Alcorn McBride website at http://www.alcorn.com. Once you locate the installation file, simply run it on your Windows PC and follow the on-screen instructions.

Alcorn McBride Binloop User’s Manual Page 47

Connecting your PC to the Binloop

There are two ways in which the Binloop software can interface to the Binloop from your PC:

1. Ethernet

2. RS-232 Serial

Connecting with RS-232 Serial

If your PC is not equipped with an RS-232 serial port, you can use a USB-to-Serial adaptor. Just make sure that the adaptor will support “MarkSpace Parity” operation.

For a list of USB-to-Serial adaptor manufacturers that support this protocol visit www.alcorn.com and use our Knowledge Base.

The Binloop software can communicate with the Binloop through a PC Serial Port via a 9-pin straight-through serial cable (included with the unit). Before this can happen, you must first connect the serial cable between a serial port on your PC and the Programmer port of the Binloop.

Once you make this connection, you are ready to use the Binloop Configuration software to program and communicate with the your Binloop.

Connecting with Ethernet

Ethernet is also a common method of interfacing the Binloop software to the Binloop. This requires a PC to be connected to the Binloop directly, or over a network, using a CAT5 (or better) rated Ethernet cable. If you want to connect directly to the Binloop from your PC (no Ethernet switch or hub) you must use a crossover Ethernet cable. When the Binloop has a good network connection, the green Link LED will illuminate.

Beyond a good physical connection, Ethernet communication requires properly configured network settings on both the Binloop and your PC. Although Ethernet network design and administration is beyond the scope of this manual, we have provided a step-by-step guide in this manual that will walk you through connecting directly to the Binloop over Ethernet using the Binloop’s default settings. Please refer to the

Application Notes section if you would like more information on this.

Playing a Test

Note: Please refer to the Media section of this manual

for more information on creating your own videos and file naming conventions for the Binloop.

This window serves as an interface for manually controlling the Binloop. This lets you test the functionality of the Binloop before you apply that functionality to any of the Binloop’s other control interfaces.

Now that you are connected to the Binloop using the Binloop Software, let’s go through an example of how you can use this software to control the Binloop in realwill demonstrate how to command the Binloop to play a video file. Before we get started, it is assumed that you already have a knownworking video assigned as clip #1 loaded onto the Compact Flash card of reproducer #1. It is also assumed that the outputs of reproducer #1 are properly connected to a video display. If these assumptions frighten you, then you should refer to the File guide located in the Getting Started section of this manual before moving on.

1. Make sure that Reproducer 1 has a flash card loaded with a video file named as clip 1 (i.e. VID00001.MPG).

2. Make sure that the Binloop, your video display, and your audio system are powered on.

3. Select BinloopReproducerControls from the menu of the Binloop Software.

If you try to play a file that does not exist on the media the Red Error LED on the Reproducer Flashes rapidly

4. Select Reproducer 1 from the list on the left-hand side. Assuming that the number of the video file you want to play is 1, you can leave the Segment number as the default (1).

5. In the Reproducer 1 Controls window, use the buttons to control the playback.

6. Click on the Play button to start the video. The status LED of reproducer 1 will turn green.

7. Click on the Stop button to stop the video.

with the same name and update the saved version with the new information, replacing the old version. If you are using a new file which has not yet been saved, will present the Save window. This window allows you to name your configuration file and choose a location to store it. The Save window is identical to the Save As window.

Save As…

The Save As… option displays a window allowing you to save your current settings in a file with a new name.

The file name defaults to the name of the file you are currently using. The name can be changed from the default by typing a new name into the File name box.

Print Setup…

The Printer Setup… selection allows you to select and configure your printer.

Once you’ve programmed some timecode triggers (explained later in this chapter) options for printing the table appear in this menu.

Print…

The Print selection prints the timecode trigger list contained in the AMB file that you’re currently viewing.

Print Preview…

The Print Preview option shows what the timecode trigger list printout will look like before you actually print it.

Exit

The final option in the File sub-menu is Exit. This allows you to exit the program and returns you to Windows. If you have made any changes to the settings, you will be asked if you want to update the unit and if you want to save the file with the current settings before you exit the Binloop application.

Alcorn McBride Binloop User’s Manual Page 53

Binloop Menu

The next selection in the main window is Binloop. It contains two groups containing selections called Settings…, SMPTE…, Reproducer, and Download to Binloop and Upload to Binloop. Each of these selections is explained in what follows.

Settings…Unit…

Many previous generations of Binloop products are supported by the Binloop Software.

Reproducer Card Slots

The Unit Configuration window permits the user to select the number of reproducers in the Binloop. The Digital Binloop and Video Binloop both have 16 slots.

Control Port Protocol

The Control Port Protocol determines the protocol that is used on the Show Control Port. This settings can be either Alcorn Show Control(Alcorn 9-bit), MIDI, ASCII (Pioneer/AMI), and Debug. For more information on these protocols, please refer to the Control Protocols section of this manual.

Unit Number

The Unit Number is the device address used for the MIDI protocol and when addressing multiple units.

Unit Groups

You can place the Binloop into a Group with other Binloops and address them as a single group. The Unit Groups selects which groups this Binloop is a member of.

Alcorn McBride Binloop User’s Manual Page 54

Settings…Connection…

This Connection Settings window provides settings for the serial COM port your using on your PC to communicate to the Binloop. It defaults to Offline.

SMPTE…Start…

You can also set a Custom Preroll Time where SMPTE Generation can begin earlier the first time it is started.

This window presents you with a Start button for starting the SMPTE interface. This window will change depending on whether you have the SMPTE interface configured to Generate or Read SMPTE.

Alcorn McBride Binloop User’s Manual Page 55

SMPTE Stop…

This option stops the SMPTE interface as well as the reproducers. A confirmation window appears with OK and Cancel.

SMPTE Configuration…

The SMPTE Configuration window allows you to set all of the parameters associated with the Binloop’s SMPTE interface.

Frame Rate

This is the Frame Rate used for generating SMPTE. The choices are

23.976, 24, 25, 29.97, 30-drop, and 30 frames-per-second.

Read External SMPTE

This button configures the SMPTE interface to Read incoming SMPTE from the SMPTE In connector.

Generate SMPTE

This button configures the SMPTE interface to Generate timecode. This timecode is used internally to process the timecode triggers, and is also fed to the SMPTE Out connector.

Alcorn McBride Binloop User’s Manual Page 56

Genlock to Video

Sync clock of the Binloop.

Only 23.976, 25 (PAL) and

29.97(NTSC) frame rates are supported when in Genlock to Video mode.

Since the A/V clock interface of the Binloop can lock to an external V-Sync source, this means that you can generate SMPTE synchronously with your video sync source as well.

When this option is selected, the SMPTE interface will generate timecode synchronously with the internal VThis ensures that the SMPTE clock and reproducers operate at the same exact rate.

Since the SMPTE clock is used as a timing reference for timecode triggers, it’s recommended that this option is enabled whenever you are synchronizing multiple video tracks. This will ensure that the reproducers start reliably in sync with one another.

Start Automatically on Power UP

If this checkbox is active the Binloop will begin Generating or Reading timecode as soon as the system reaches the ‘Ready’ state.

Preroll Time

This is the timecode value at which the SMPTE generator will begin when first started.

Start Time

This is the time at which SMPTE timecode will loop back to when it is looping, or when a restart condition has occurred.

End Time

This is the time at which SMPTE will stop or loop (depending on the Loop setting).

Loop SMPTE at End Time

If this option is enabled, then the SMPTE generator will loop back to the Start Time when the End Time is reached.

Allow Start Input to Restart SMPTE

When this option is enabled, a SMPTE Start command from any control interface will cause the SMPTE generator to jump back to the Start Time.

SMPTE Muted When Stopped or Paused

When SMPTE is paused or stopped, SMPTE output will be muted when this checkbox is active. If this checkbox is inactive, the current frame will be repeated over and over again when timecode is paused or stopped.

Version – Get Version

This allows you to get the current firmware version of the SMPTE interface on your Binloop’s Controller card.

Alcorn McBride Binloop User’s Manual Page 57

Reproducer…Controls…

When you select this menu item, the Reproducer Controls window appears.

This window presents many controls that are good for playback testing and troubleshooting. Each is explained below. The next menu item allows you to select an individual Reproducer to control.

Please refer to the Media Files section of this manual for the correct way to name and number files.

Socket

This setting is intended only for legacy Binloop systems with dual flash sockets, and does not apply to the modern Digital Binloop or Video Binloop. This setting should be left at the default value of ‘Primary’

Segment

The Segment refers to the particular video or audio file that you want to play. It is a number referring to the file number on the media.

You can Search a video file so that when you click Play it will begin playing immediately. Entering an time in the adjacent box will search to an offset within the video or audio file. The default value of 00:00:00.00 will search to the beginning of the clip.

Audio Channels

This setting is used for audio-only playback from the left or right channel. If you use the default setting of Stereo or Mono, audio and video clips play normally on both channels (mono clips are duplicated on the left and right audio outputs). However, if you wish to play a mono audio clip on only one of the audio outputs, you may select the Independent option.

Alcorn McBride Binloop User’s Manual Page 58

Colorspace

RGB is actually RGsB /w sync on green.

This setting allows you to configure the component video output Colorspace as either RGB or YUV.

Play

This will cause the selected Reproducer to Play the selected file segment. Clicking Play again will start playback over from the beginning.

Play Next

If a file is currently playing, clicking the Play Next button will queue the specified file segment to play immediately after the current file is finished playing.

Pause

This causes the currently playing file to stop. Clicking Play will cause it to continue playback from where it was paused.

Mute Audio, Mute Video

These buttons cause the audio and video to be muted, respectively. When video is muted, the video outputs are black.

Important: You should always Format the media in the Binloop before you use it.

Note: By grouping the reproducers together, Reproducers can be simultaneously commanded using any of the Binloop’s control interfaces.

Un-Mute Audio, Un-Mute Video

These buttons cause the audio and video to be un-muted, respectively.

Media Utilities

This button accesses another window that allows you to Format the compact flash media on the selected Reproducer. Formatting will erase the contents of the flash card.

Reproducer Groups

Reproducers can be assigned to Groups using this selection. A Reproducer that is a member of a Group will respond simultaneously with other members to any command that is addressed to the Group. This provides the ability for one Play command to trigger synchronized multi-channel video playback.

Alcorn McBride Binloop User’s Manual Page 59

You can assign a Reproducer to be a member of more than one Group. Below is a screenshot showing the Group assignment window. This example assigns Reproducers 5, 6, 7, and 8 to be members of Group 1.

Status…

You can determine that current playing status of each Reproducer by opening the Status window. When this window opens, select Refresh and after a brief moment each Reproducer will report their current status.

A timeout message appears if no Reproducer is installed in the slot.

Any errors that exist will be reported in the lower part of this window.

A Word About Trigger Latency:

possible, the reproducer will wait a consistent amount of time after the

that every reproducer that received this command starts playing at the

The Binloop uses two different types of Play commands. The first one, called “Unsynchronized Play” is used mostly for “point-source” or other audio/video applications where synchronization between channels is not important.

The other type of Play command is called “Synchronous Play”. This command needs to be used in those situations where absolute frame synchronization is required across channels. This is the type of play command issued by the Play action. There are important differences between how the Binloop reacts to these two commands.

Unsynchronized Play Latency

When this type of play command is sent to a reproducer, it starts playing the file as soon as it possibly can. The latency is determined only by the amount of time it takes the reproducer to process the play command, load the clip from the compact flash card, and begin decoding and playing the file. This latency is very short, but it is not predictable. For that reason, this command is not recommended for use when the goal is to synchronize playback between multiple reproducer cards. The unsynchronized play command is normally used for applications that require multiple channels of video that are unrelated to one another (like individual kiosks, etc.).

The exact amount of latency time will depend on the SMPTE frame rate being used.

When using Play commands from the Timecode trigger list, it is highly recommended that the SMPTE clock is locked to V-Sync. This ensures that the timecode framerate and the video framerate of the reproducers is synchronous.

Synchronized Play Latency

A Synchronized Play is the same as an Unsynchronized Play with one key difference. Rather than playing the video as quickly as

play command was received before playback starts. This ensures

same time.

The default latency between when the play command occurs and when the file actually starts playing is exactly 16 frames for a Synchronized Play. This delay provides the reproducer with more than adequate time to process the command and load the video from the compact flash card so that it’s ready to start playing when the consistent wait period is over.

Use the Synchronized Play command for playing groups of Reproducers, which must start playback in perfect synchronization (i.e. multi-channel music tracks or video wall presentations).

CobraNet

Description

Details

CobraNet is an industry standard interface for distributing multiple channels of audio over an Ethernet based network. This is useful for both transmitting audio over long distances, as well as easily interfacing to CobraNet compatible systems using a simple Ethernet cable rather than many individual analog connections.

CobraNet is digitally encoded audio over Ethernet, and as such it does not suffer the effects of long distance analog transmission issues. It is not within the scope of this manual to provide a detailed installation and implementation of CobraNet; however, feel free to contact Alcorn McBride for additional details.

CobraNet uses standard Ethernet packets and network infrastructure (controllers, hubs, repeaters, switches, cabling, etc.).

CobraNet "Y" Cable

There are two, separate CobraNet interface components to the CobraNet card. The first set of Binloop reproducers (1-8) are on one of the CobraNet interfaces. The second set of reproducers (9-16) are connected to the second, slave CobraNet interface.

These two, separate CobraNet interfaces are merged into a single Ethernet jack on the rear of the Binloop. Reproducers 1-8 are available only on the 1st half of the "Y" cable labeled "2". Reproducers 9-16 are available on the second half of the cable labeled "3".

The reason for this is that it allows 24bit audio for all 16 channels in a single CobraNet interface. CobraNet interfaces supports 7 channels of audio at 24bit rates per bundle for a maximum of 4 bundles. The CobraNet interface does support 8 channels of 20bit audio per bundle.

A diagram and pin out of the cable is shown in the following diagram.

Alcorn McBride Binloop User’s Manual Page 67

Note: the second, slave CobraNet interface for reproducers 9-16 must be connected to the same CobraNet network as the first, master CobraNet interface for reproducers 1-8 for proper operation.

Bundle

The “Bundle” is the term used for the network channel in which the sending device will connect with the receiving unit. Many audio channels can be transmitted within a bundle. Bundle numbers 0-255 are defined as “Multicast” point-to-many channels and bundles 256-65279 are “Unicast” or point-to-point transmissions.

Controls and Indicators

The Binloop is normally controlled either internally using a configuration loaded from our Binloop software, or remotely from an external control system. However, the product does have several controls and status indicators located on the front panel.

Unit Status LED’s

On the front of the Binloop are nine LED's corresponding to the status of the unit. Below is a brief description of their meaning:

Power (Green) - Power is being applied to the unit.

Fault (Yellow) - The unit has detected a fault condition.

VSync (Red) -

and is locked to it.

Gen (Red) - The unit is actively generating SMPTE timecode.

Ready (Red) - The unit is ready to accept commands. This LED

should almost always be on.

Run (Red) – is active.

Pause (Red) - This LED is illuminated during SMPTE generation when the Pause button has been pressed End or Loop Time is pending.

Stop (Red) - This is illuminated whenever the SMPTE Generator/Reader is idling and ready to begin SMPTE generation or external SMPTE synchronization.

Mute (Red) - This LED is illuminated when the Mute button on the unit has been pressed. This indicates that the audio outputs of all reproducers are muted.

Alcorn McBride Binloop User’s Manual Page 73

Control Buttons

If the Binloop is configured to generate timecode, pushing

Pressing this button toggles between muting and unmuting

Directly beneath the Unit Status LED's, there are four control buttons. Their functions are defined briefly here but they will be discussed in more detail over the course of the next two chapters:

Start - If the Binloop is programmed to generate SMPTE, pushing this button starts the generation of timecode. If the Binloop is programmed to read external timecode, this causes the unit to start listening for external timecode. If SMPTE is already being generated, this button can be optionally configured to restart the SMPTE clock.

Pause – This button is only applicable when the Binloop is configured to generate and loop SMPTE. Pushing this button causes the SMPTE generation to pause the next time the configured End Time (the loop point) is reached. After this button is pressed, the Pause status LED will illuminate.

Reset – this button halts the generation. If the Binloop is configured to read external timecode, this button causes the Binloop to ignore any incoming timecode. In addition, pressing this button stops playback on all reproducers.

Mute – the audio outputs of all reproducers. When this button is in the mute position, the reproducer status LED’s will be red to indicate that they are muting the audio output. The Mute status LED will also be illuminated in this case.

Alcorn McBride Binloop User’s Manual Page 74

Display and Menu Wheel

The Binloop is equipped with a 2x16 character Vacuum-Fluorescent Display. This display is primarily used to indicate the current status of the Binloop. Here’s an example of that status display:

The current SMPTE mode is indicated at the top-left of this screen. The 3 possible modes are displayed as Gen, Gen* (Generate /w VSync), and Read. The current state of the SMPTE generator/reader is displayed at the bottom left, and the SMPTE frame rate is displayed at the bottom right. The time at the top-right of the display represents the current SMPTE timecode value in hours, minutes, seconds, and frames. In the event that there is no current timecode value (meaning timecode is not currently being read or generated), this time will be displayed as dashes like the following example:

In addition to providing system status, the display can also be used in conjunction with the nearby Menu Wheel to access the configuration settings of the Binloop. To enter this menu, simply press in the menu wheel.

Note: The menu wheel ‘clicks’ when rotated to provide tactile feedback between selections.

Alcorn McBride Binloop User’s Manual Page 75

After you do this, you can navigate through the various settings of the Binloop by rotating the menu wheel to change the selection, and pressing it to select the current item. When you are finished, simply browse to the ‘Exit’ selection and push the menu wheel to return to the status screen. To see a complete map of this menu interface, refer to Appendix D - Wheel Menu Map.

Media Files

File Types

The reproducer cards within the Binloop support a variety of common industry-standard audio formats, as well as the popular MPEG-2 video format. To play properly in the Binloop, however, the files loaded onto the Compact Flash cards must adhere to some specific encoding and file-naming requirements. This section provides detailed information on those requirements so that you can successfully create and load content into the Binloop.

The possibilities of storing audio and video content in a digital file format are nearly endless, and it’s impossible for the Binloop to support everything. Instead, the Binloop supports the specific file types which are listed below:

• MPEG2 Program Stream (Video and Audio)

• Windows PCM - WAV (Audio Only)

• Apple AIFF (Audio Only)

• Raw PCM (Audio Only)

The audio-only formats are easy to explain. They are simply audio files that are created using the associated uncompressed audio format. These files can hold up to 2 channels of audio information (Stereo), and can have a variety of other parameters which are discussed later in the Audio Formats portion of this section.

An MPEG2 Program Stream is a little more involved, but is necessary to play video in the Binloop. A Program Stream contains both a video and audio that are intended to play simultaneously. It can do this because both the Video track (Video Elementary Stream) and Audio track (Audio Elementary Stream) are combined (multiplexed) into single file. The Video portion of the stream must be a MPEG2 video that follows the specifications listed later in Video Formats portion of this section. The Audio stream contained within the program stream can be one of several formats, including MPEG-1 Layer 2 audio or Dolby Digital AC3. These types are covered in more detail later in Audio Formats portion of this section.

Alcorn McBride Binloop User’s Manual Page 85

File Naming

A specific file naming convention is used so that the Binloop can identify the file type, as well as associate the file with a number. Here is a table that shows the naming conventions based on the type of file that is being named:

File Type File Naming Style

MPEG2 Program Stream (Video+Audio) VIDnnnnn.MPG

Windows PCM (Audio) SNDnnnnn.WAV

Apple AIFF (Audio) SNDnnnnn.AIF

Raw PCM 16-bit Mono (Audio) SNDnnnnn.AMS

Raw PCM 16-bit Stereo (Audio) SNDnnnnn.SFD

*Raw PCM 24-bit Mono (Audio) SNDnnnnn.A24

*Raw PCM 24-bit Stereo (Audio) SNDnnnnn.S24

*Only supported by the Repro24D (Digital Binloop)

As you can see from this table, the files are identified based on the file extension. For example, the Binloop will identify a file with an extension of MPG as an MPEG2 Program Stream containing video and audio. A file with the extension of SFD would be treated as a 16-bit Mono Raw PCM audio file.

The file number is determined by the 5-digit ‘nnnnn’ portion of the file name. The Binloop supports files that are assigned numbers between 0 and 1023, so this part of the filename is always represented as 00000 through 01023.

Just as an example, let’s say you wanted to create a Program Stream (Video file) that you wanted to associate as file #123. To do this, you would need to rename the video file to VID00123.MPG.

Note: Every file on the media must have a unique number in the file name, no duplications are allowed. If you have duplicate file numbers (i.e. two files associated as file #1), the Binloop would consistently choose only one of those files when told to play the associated number.

Alcorn McBride Binloop User’s Manual Page 86

Video Formats

As stated earlier, the reproducers in the Binloop support only one commonly used MPEG2 file format; the MPEG2 Program Stream. This MPEG2 Program stream MUST contain a video AND an audio track. Even if you do not wish to have audio for your application, you must at least have a blank audio track. For supported audio formats, see the Audio Formats section. The next section describes the supported parameters for the video portion of the Program Stream.

MPEG-2 Video Specifications

The decoder within the Binloop is compliant with Main Profile at Main Level MPEG-2 specified in ISO/IEC 13818. The following table summarizes the recommended encoding parameters for creating MPEG-2 video that is compatible with the Binloop:

Setting Values

Profile Main

Level Main

Max Bitrate* 15Mbps (15000kbps)

Resolutions 480p, 480i – 720x480

Framerates** NTSC Interlaced – 29.97fps

Aspect Ratios 16:9 & 4:3

Chroma Format 4:2:0

576p, 576i – 720x576

NTSC Progressive – 29.97fps , 59.94fps

PAL Interlaced – 25fps

PAL Progressive – 25fps, 50fps

* Both Constant (CBR) and Variable (VBR) bitrate are supported, so long as the bitrate does not exceed the maximum.

** The framerate is very important when encoding for the Binloop, especially in synchronous playback applications. Only these 4 settings should ever be used. Which one of the 4 depends on whether the Binloop is configured for NTSC or PAL video systems, as well as the type of frame encoding used (interlaced or progressive).

Alcorn McBride Binloop User’s Manual Page 87

Audio Formats

The type of audio format that you choose to use first depends on one simple question: Will you be using the Binloop to play only audio, or will you be playing video? If you are only playing audio, you can create one of several types of uncompressed audio files. These file types are discussed in Uncompressed Audio Formats. If you are creating an MPEG2 Program stream for the purposes of playing video, you must include an audio track that is compatible with the Program Stream format. These formats are discussed in MPEG2 Program Stream Audio Formats.

MPEG2 Program Stream Audio Formats

When encoding video files as Program Streams, it is required that you have audio along with video. Here are the audio formats that you are permitted to use within the MPEG2 Program Stream:

1. MPEG Audio

2. Dolby Digital Audio (AC3)

MPEG Audio Specification

Parameter Options

Format: MPEG-1 Layer I/II, MPEG-2 Layer II

Mode: Stereo, Mono

Sample Rate: *32kHz, *44.1kHz, *48kHz

Max Bitrate: 384kbps

Emphasis: Off

* For synchronization, the Binloop uses a global sample rate clock used throughout the entire system. This means that it is ABSOLUTELY CRITICAL that the sample rate used to encode files matches the sample rate configuration of the Binloop cage. A mismatch between the two will result in both audio and video playback issues.

Alcorn McBride Binloop User’s Manual Page 88

Dolby Digital AC3*

Uncompressed Audio Formats

When creating audio-only files for playback in the Binloop, there are several common formats to choose from. They are:

1. Windows PCM (WAV)

2. Apple AIFF

3. Raw PCM

The following table outlines the specifications for using any of these file formats:

Parameter Options

Format: WAV, AIFF, Raw PCM

Mode: Stereo, Mono

*Sample Rate: 32kHz, 44.1kHz, 48kHz, **96kHz

Quantization: 16-bit, **24-bit

** These options are only supported by the Repro24D, which are typically installed in the Digital Binloop (not the Video Binloop).

If the File Splitter software is no longer available, please obtain the latest manual from the Alcorn McBride website, or contact technical support for the latest recommended method for splitting files.

The split-file playback feature requires reproducer firmware V1.64 or newer to work.

The Binloop reproducers use a special implementation of the FAT32 file system. This file system is widely used, and will allow your flash cards to be accessible from any Windows based PC or MAC computer.

Although the supported volume size of Compact Flash cards is much larger, the maximum file size supported by the FAT32 implementation in the

to 4GB) to the flash card, but the reproducer will not be able to access this file. This will result in a fault condition (Red flashing LED) if you attempt to play the file.

If your application requires a longer playback time than a 2GB limitation will allow, the best solution is ‘split’ the file into several segments using a filesplitting program. One suggestion is a software package called File Splitter, which can be downloaded at http://www.filesplitter.org/. Using this method, a large file can be separated into several segments which a reproducer can treat as a single coherent video file. Here’s how it works.

Let’s say that you have encoded a 5GB video file (Program Stream) that you want to play in the Binloop. First, you will need to use a utility (like File Splitter) to divide this file into several chunks smaller than 2GB. To be safe, you could divide the file into 1GB chunks. When the splitting process is complete, you should have 5 files. Rename those files like this:

VID00001.MPG

VID00001.001

VID00001.002

VID00001.003

VID00001.004

Keep in mind that VID00001.MPG is the first segment, VID00001.001 is the

them to the reproducer’s Compact Flash card.

At this point, all you have to do is treat VID00001.MPG as you normally would. For example, if you send a command to Play File #1, the reproducer will automatically play through all of the file chunks without you having to do anything special. You can also send a command to Loop File #1, and the entire file will loop from start to finish just as you would expect.If your application requires a longer playback time than a 2GB limitation will allow, the best solution is to create separate files and ‘seam’ them together using the ‘Play Next’ command.
