About this Guide

This guide contains installation, conﬁguration, and operating information for the VNM Recorder.

In this guide:

z The term "recorder" refers speciﬁcally to the VNM Recorder.

z The term "codec" refers to either a VN‑Matrix encoder or decoder.

z The term "stream" refers to multimedia that is constantly received by (and normally

presented to) an end‑user while being delivered by a VN‑Matrix encoding device.

z The term "element" refers to the video/graphics, audio, data, and whiteboard

(user data) content that is contained within a stream.

About the VNM Recorder

The VNM Recorder connects to a network and is used to digitally record and play back multiple PURE3® streams via the IP network of VN‑Matrix encoders and decoders. The VNM Recorder is used with any VN‑Matrix application to document, archive, review, and play back highly sophisticated or demanding AV imagery.

The VNM Recorder has the ability to record PURE3 encoded IP streams on each channel. Up to ﬁve PURE3 streams can be recorded or played back on a single recorder. PURE3 streams recorded together maintain proper synchronization on playback.

The VNM Recorder uses a network storage architecture which makes systems highly scalable and ﬂexible. Storage capacity can be increased or decreased based on the number of inputs, recording time, and archiving requirements.

VNM Recorder • Introduction 1

Figure 1 shows a typical VNM Recorder application, which includes a single VN‑Matrix

codec. The application shown in ﬁgure 1 can operate in recording mode or playback mode.

Overview of Recorded Streams

The following information is associated with recorded streams when using the VNM Recorder.

z Recorded streams are stored as ﬁles on the VNM Recorder.

z Each recording contains (as a minimum) a video element.

z A recording may also include elements containing audio, data, and whiteboard

information (if these are present and enabled at the encoder). If these are selected for storage, each element is stored as an individual ﬁle under the same directory.

z Each recording may contain up to ﬁve channels.

z Each channel originates from a VN‑Matrix encoder device (or a VN‑Matrix codec

conﬁgured as an encoder).

Overview of Stream Playback

The following information is associated with stream playback when using the VNM Recorder.

z When a recording is selected for playback that contains multiple elements, the

necessary ﬁles and channels (a maximum of ﬁve channels are supported) are loaded.

z The ﬁles that are loaded in each channel are treated as a single recording and may

not be split.

z The video content, which is assigned to channel 1, is always played.

z The audio, data, and whiteboard elements may be enabled or disabled for playback

(when present in the recording).

z During playback, the audio, whiteboard, and data elements are always slaved to

their respective video stream. In other words, all channels are slaved to the video stream on channel 1.

VNM Recorder • Introduction 2

About RAID5 Storage

RAID storage is a system which allows hard drives to be linked together to form a single large capacity storage device that offers superior performance, storage capacity, and reliability over other storage solutions.

The VNM Recorder uses RAID5 storage. RAID5 storage provides the following advantages.

z Increased storage performance.

z Full data redundancy which allows for data backup in the event of a hard drive failure.

z A hard drive is set aside as a hot spare drive which is used to automatically rebuild the

data of a failed drive and allow the system to recover.

Transport Protocols Used for Streaming

The source data from a VN‑Matrix encoder can be distributed to multiple displays/decoders (one‑to‑many) or to a single display/decoder (point‑to‑point). A previously recorded stream can be distributed in the same way and may be thought of as an encoder in this context.

A stream may be transported from the source (encoder, recorded stream) to the display (decoder) using one of three methods:

z Multicast Real‑time Transport Protocol (RTP)

z Unicast Real‑time Transport Protocol (RTP)

z Unicast Transmission Control Protocol (TCP)

By default, the VNM Recorder provides a choice of unicast RTP or unicast TCP transport protocols. A multicast transport protocol may be conﬁgured if required (see Multicast

Enable on page 40 of the Conﬁg Page section).

NOTES:

• During playback of a recorded stream, the default transport protocol used is unicast

R T P.

• When a stream is recording, the VNM Recorder may be considered as a display

(decoder) device.

VNM Recorder • Introduction 3

Multicast RTP — An Overview

Multicast RTP allows a source to be displayed on multiple displays. This method uses a real‑time variation of UDP (User Datagram Protocol) called RTP (Real‑time Transport Protocol).

DISPLAYS

Figure 2. Multicast RTP Streaming

The source encoder uses RTP to send data to a multicast group. The source does not need to know the IP address of the decoders that are using the source.

RTP provides very low latency which is important for video streaming. Unlike other protocols, RTP packets include a time stamp. If packets are received in the wrong order, they are sorted into the correct order for display or discarded if the time stamp is out‑of‑date.

However, because RTP is a connectionless protocol, data delivery is not guaranteed. When data packets are lost (for example, due to excessive network trafﬁc), the VN‑Matrix 200 / 225 / 300 / 325 devices carefully manage the data stream to minimize any image disruption.

VNM Recorder • Introduction 4

Unicast RTP — An Overview

Similar to multicast RTP, this method uses a real‑time variation of UDP protocol, called unicast RTP. This method can be used where the network infrastructure does not support multicast trafﬁc. Typically, this protocol is used for point‑to‑point conﬁguration (single source to single display), but can be conﬁgured to use up to a maximum of four displays.

NOTE: The encoder sends an individual stream to each decoder. This means that the

total bandwidth of the VN‑Matrix system increases as more decoders are added.

VNM Recorder • Introduction 5

Unicast TCP — An Overview

This method transports data using standard TCP (Transport Control Protocol) and should only be used for single point‑to‑point transfer of data.

TCP is a connection‑based protocol and, therefore, data is guaranteed to be delivered. However, in the event of excessive network trafﬁc, delivery may be delayed which will impact real‑time performance.

VNM Recorder • Introduction 6

Denitions

PURE3 — PURE3 is speciﬁcally designed for network transmission of real time media (such as video or graphics, audio, data, and whiteboard elements). It features both spatial and temporal image compression, which allows for efﬁcient bandwidth usage.

z PURE3 streams always contain video or graphic elements.

z PURE3 streams may contain audio, data, and whiteboard elements that are associated

with the video and graphic elements.

Streaming media (stream) — This term refers to multimedia that is constantly received by (and normally presented to) an end‑user while being delivered by a streaming provider. Internet television is a commonly streamed medium. Streaming media (stream) in this guide refers to a PURE3 media stream that is produced by a VN‑Matrix encoding device.

Device license — This term refers to the number of licensed features that are available on a device within a VN‑Matrix system. All devices contain a default license that offers a default level of functionality. See Licensed Features panel on page 29 of the Recorder Device

Page section for information about device licenses.

NOTE: The VNM Recorder contains a default license that allows for ﬁve recorder

channels and ﬁve player channels. It is currently not possible to change the license on the VNM Recorder.

Controller license — This term refers to the license that is supplied to the device designated as the system controller. See Controller Licensing on page 42 of the

Accounts Page section for information about controller licenses.

Data — This refers to the transfer method of data between an encoder and a decoder. Data

input is created at the encoder, placed into the PURE3 stream, and sent to the decoder. The data is received in the same form that it was transmitted. This method of data transfer is unidirectional and can only be sent from an encoder to a decoder.

Whiteboard (wb) data — Also known as annotation data, whiteboard data outputs text and/or simple pointer annotation onto local displays that are connected to VN‑Matrix encoders or decoders. This type of data is bidirectional, which allows a decoder to send whiteboard data to an encoder.

Features

z Record, synchronize, and play back up to ﬁve visually lossless PURE3 encoded VN‑

Matrix streams over IP.

z Digitally record and play back video/graphics, audio, and data.

z Virtual switching of video, graphics, and audio over IP.

z Point to point and long distance distribution.

z Link multiple recorder units together for applications requiring recording for more than

ﬁve streams.

z The VNM Recorder is a scalable and ﬂexible system.

Choosing the Controller Device

In any VN‑Matrix system, one device needs to be conﬁgured as a controller. The controller acts as a central point of reference for each device, manages all of the system communications to every matrix device present, and also serves the web‑based control interface to the user.

NOTE: The VNM Recorder is conﬁgured as a controller when shipped. The controller

address is set to the same value as the eth0 port (192.168.254.254).

The controller can be one of the following devices.

z VN‑Matrix 200, 225, 300, or 325 device which is suitable for small network systems

z VNM Recorder which is suitable for small network systems

z VNM Enterprise Controller which is suitable for large network systems

When a controller device has been chosen, all devices within the VN‑Matrix system must reference the IP address of the controller device. When conﬁguration of the VN‑Matrix system is complete, the IP address of the controller device can be entered into a suitable web browser running on any PC or laptop connected to the VN‑Matrix network.

For information on how to conﬁgure the VNM Enterprise Controller, see the VNM Enterprise Controller User Guide. For information on how to conﬁgure the VN‑Matrix encoders and decoders, see the VN-Matrix 200 Series User Guide, VN-Matrix 225 Series User Guide, VN-Matrix 300 User Guide, and the VN-Matrix 325 User Guide.

VNM Recorder • About the Web-based User Interface 35

Selecting a recording for replay

The initial selection of a recorded stream is made by clicking on the appropriate ﬁlename shown in the Listing Directory (also known as the Content Directory; see e in ﬁgure 23 and the About the Content Directory section on page 43 for more information). This loads all of the content that contains the same preﬁx name and that was recorded at the same time as the selection. Up to ﬁve channels, each containing different sets of elements, can be loaded. After the content has been loaded, the user can edit the playback start and finish times. This is only permitted within the current bounds of the recording time displayed on channel 1 (also known as video‑player0).

NOTES:

• If any streams in a recording are not required for playback, they can be removed by

unchecking their boxes and clicking Update.

• During replay, the audio, whiteboard, and data streams are always slaved to their

respective video stream. All streams are slaved to the video stream on channel 1.

• The default transport protocols that are used during replay are unicast RTP and

unicast TCP, depending on the selection made at the corresponding decoder device. If necessary, the multicast RTP transport protocol may also be enabled (see Multicast

Enable on page 40 of the Conﬁg Page section).

The other features of the Player page are detailed below.

Playback Controls — When a media ﬁle as well as the start and finish times have

been selected, playback can be controlled using the play, pause, and stop buttons (see the icons below). During active playback, a bookmark can be created using the bookmark button (see the icons below). Clicking on this button sets a reference point within the stream that can be retrieved later. A new reference point is placed within the stream each time the button is pressed and allows for multiple reference points to be set. For more information on bookmarks, see the Using Bookmarks section on page 54.

Stop Pause Play Bookmark

NOTE: Attempts to create a bookmark while content is not playing will be ignored.

netSlave — When multiple player systems are managed by a single controller, it is

possible to synchronize their start and pause operations during playback. This can be conﬁgured by selecting a suitable netSlave. The netSlave can be set to either Local

NetMaster

z When Local NetMaster is selected, the local player is either standalone or the

master of a group (if another player in the system selects it as netSlave). Figure 23 shows what a Player page would look like with Local NetMaster selected.

z When set to the name of another player, the local player becomes a network slave.

Playback sessions start and pause synchronously, but requires separate play and pause commands to be issued on each local master player (for example, a playback channel waiting for a remote system to start or pause will show the

NSYN status).

Mounting

This section outlines the various mounting options available for the VNM Recorder.

z Tower Installation

z Rack Installation

Tower Installation

Attach the appropriate feet to the unit and place it in a well ventilated area. The tower can be placed on its side (horizontally) on a hard surface with the cover latch facing up or placed standing up (vertically) on a ﬂat surface.

Rack Installation

This section provides information on installing the recorder into a rack cabinet. Rack installation requires the use of the rack mount kit, which is included with the VNM Recorder.

There are a variety of rack cabinets on the market, which may mean the assembly procedure will differ slightly. If necessary, refer to the instructions that came with the rack cabinet to complete the rack installation.

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products in a rack:

1. Elevated operating ambient temperature — If the unit is installed in a closed or

multi‑unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (TMA: +122 °F, +50°C) speciﬁed by Extron.

2. Reduced air ﬂow — Install the equipment in the rack so that the equipment gets

adequate air ﬂow for safe operation.

3. Mechanical loading — Mount the equipment in the rack so that uneven mechanical

loading does not create a hazardous condition.

4. Circuit overloading — Connect the equipment to the supply circuit and consider the

effect that circuit overloading might have on overcurrent protection and supply wiring. Consider the equipment nameplate ratings when addressing this concern.

5. Reliable earthing (grounding) — Maintain reliable grounding of rack‑mounted

equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).

VNM Recorder • Mounting 72

Rack Mounting

Outer rail

The supplied rack mount kit includes two rack rail assemblies. Each of these assemblies consist of three sections: an inner ﬁxed rail that secures to the recorder frame, an outer rack rail that secures directly to the rack itself, and two rail brackets that also attach to the rack (see ﬁgure 39).

Inner rail

Figure 39. Identifying the Sections of the Rack Rails

To install the recorder into a rack, follow the steps below.

1. Remove the inner rail by pulling it out as far as possible. The locking tab should lock the

Rail brackets

rail and make a clicking noise when fully extended. Depress the locking tab to pull the inner rail completely out. Do this for both assemblies (one for each side).

NOTE: The rails have a locking tab, which serves two functions. The ﬁrst is to lock

the recorder in place when installed and pushed fully into the rack. Secondly, these tabs lock the recorder in place when fully extended from the rack to prevent pulling the recorder completely out of the rack.

2. Place the recorder on its side (horizontally) on a hard surface with the cover latch

facing up.

3. Remove the top and right covers by ﬁrst removing the screws that secure them to the

frame. Depress the button on the top of the frame to release and remove the cover. Remove the screws from the feet and remove them from the frame (see ﬁgure 40).

VNM Recorder • Mounting 73

4. Attach the rack handles to the inner rails.

5. Align each inner rail (with the rack handle attached) to the screw holes located on the

left and right side of the recorder. Secure the rails to the sides of the recorder frame (see ﬁgure 41).

NOTE: The two inner rail assemblies are left and right speciﬁc.

Figure 41. Installing the Rails onto the Recorder Frame

6. Determine where the recorder will be located within the rack (refer to the

UL Guidelines for Rack Mounting section on page 72 for safe rack installation).

7. Position the rail brackets at the desired location in the rack. Screw the rail brackets

securely to the rack. Attach the remaining rail brackets to the other side of the rack, making sure both sets are at the exact same height.

NOTE: The smaller rail bracket should be positioned at the front of the rack and

the larger rail bracket should be positioned at the back of the rack.

VNM Recorder • Mounting 74

8. Secure the outer rails to the rail brackets.

NOTE: The two outer rails are left and right speciﬁc.

9. Line up the inner rails on the recorder with the outer rails on the rack. Gently slide the

recorder into the outer rails of the rack (see ﬁgure 42). Depress the locking tabs, if necessary, when sliding the recorder into the outer rails.

10. Connect the necessary devices to the recorder (see the Front Panel Features section

on page 8 and the Rear Panel Features section on page 10).

11. When the recorder is pushed completely into the rack, the locking tabs make a clicking

noise. If necessary, secure the rack handles to the rack to keep the recorder in a ﬁxed position.
