7550 OVERVIEW

The 7550 Video Processing Frame Synchronizer accepts a high definition or standard definition video signal for processing, synchronization, and timing.

The module’s main features are summarized below:

• HD or SD SDI I/O (output follows input)

• Full-featured Frame Synchronizer

• Comprehensive Proc Amp Controls

• Pixel by pixel Legalizer for Y, Cr, Cb or RGB requirements

• External genlock reference signal

• EDH detection and insertion

• Internal Test Signal Generator

• Automatic Standard Detection

• Memory Registers

• Accepts the 8415 Audio Processor submodule option for tracking audio delay, audio mixing, and shuffling

The 7550 modules provides flexible synchronization with an infinitely adjustable timing system that genlocks to your house reference. The module will genlock to either composite video (PAL or NTSC) or to HD Tri-level Sync. It can also lock to the frame’s master reference or a reference can be connected directly to the module’s external reference BNC. The serial output timing can be set anywhere within a frame of the selected input reference. Frame delay for an asynchronous input can be set for up to 3 frames.

Upon loss of signal, the 7550 provides freeze frame or black on the output until the signal is recovered. In freeze mode, audio can be muted or passed as desired.

The input is carried at full, uncompressed bandwidth throughout the entire module for uncompromised picture quality. EDH monitoring of the digital input is provided to alert the user to an incoming problem. EDH detection, monitoring and insertion are standard on the 7550. Flags are reported through the Avenue PC application.

As shown in the block diagram on the following page, the 7550 has a full-featured Proc Amp with adjustment for every signal parameter. Video Proc controls include video and chroma gain, NTSC style hue rotation, black balance and pedestal.

A Legalizer can be enabled that will inhibit the picture on a pixel by pixel basis to be within legal limits for RGB requirements. A Y, Cr, Cb legalizer provides clip controls for adjusting the picture white and black clipping and chroma limiting as desired for your application.

7550-2

An 8415 Audio Processor submodule can be installed on the 7550 module. The 8415 is an eight channel processor designed to provide superior handling of embedded audio. The disembedder on the input side follows the timing of the video input, even if that input is asynchronous to the house reference. The embedder on the output side is synchronous to house. This allows embedded audio to be safely bypassed around the video Framestore to properly preserve re-synchronized embedded audio for correct lip sync. The Control modules in the frame (5030 or 5035) must be running software version 2.0.5 or later for proper operation of the 8415.

Every function and parameter on the 7550 and 8415 can be controlled from an Express Panel, Avenue Touch Panel, or the Avenue PC Control Application. Memory registers can be used to save the complete configuration of the module, making it easy to change instantly between different configurations.

Ten 7550 Video Processors (including the 8415 Audio option) can be accommodated by the Avenue 3 RU frame or four modules can be installed in the 1 RU frame.

Modules at software version 2.2.0 or later support SNMP (Simple Network Management Protocol) monitoring. For each applicable signal processing module, module, signal, and reference status are reported. For complete details on using SNMP monitoring, refer to the Avenue System Overview in the manual that accompanies each frame.

APPLICATIONS

This section provides two typical applications for utilizing the full versatility of the 7550 Video Processor module and the optional 8415 submodule.

Timing of an Asynchronous Input

As shown in the illustration below, the 7550 module with an 8415 audio submodule can accept an asynchronous video input such as the feed from a satellite receiver. The module can time the signal to a house reference and send the timed output to a router for distribution throughout the facility. With the 8415 audio submodule installed, the audio lip sync of the input signal is preserved.

Embedding AES Audio

In the example shown below, the 7550 module with an 8415 audio submodule is embedding AES audio into the SDI output of a production switcher. The Proc Amp on the 7550 is used to make final adjustments to the video which is then output to a video server.

INSTALLATION

8415 Submodule Installation

The optional 8415 Series submodule installs on the component side of the 7550 Video Processing module circuit board. If the option is ordered with the 7550 module, it will come already installed.

To install the 8415 audio submodule, locate the three connectors on the left side of the circuit board as shown below and line the connectors up, checking the alignment. Press carefully into place to seat the submodule.

Note: Operation of the 8415 Audio submodule requires that the Control module (5030/5035) in the frame be running version 2.0.5 software or later.

7550 Video Processing Module

Plug the 7550 module into any one of the slots in the 1 RU or 3 RU frame and install the plastic overlay provided onto the corresponding group of rear BNC connectors associated with the module location. Note that the plastic overlay has an optional adhesive backing for securing it to the frame. Use of the adhesive backing is only necessary if you would like the location to be permanent and is not recommended if you need to change module locations. This module may be hot-swapped (inserted or removed) without powering down or disturbing performance of the other modules in the system.

MODULE CONFIGURATION AND CONTROL

The configuration parameters for each Avenue module must be selected after installation. This can be done remotely using one of the Avenue remote control options or locally using the module front panel controls. Each module has a Remote/Local switch on the front edge of the circuit board which must first be set to the desired control mode.

The configuration parameter choices for the module will differ between Remote and Local modes. In Remote mode, the choices are made through software and allow more selections. The 7550 Parameter Table later in this section summarizes and compares the various configuration parameters that can be set remotely or locally and the default/factory settings. It also provides the default User Levels for each control. These levels can be changed using the Avenue PC application

If you are not using a remote control option, the module parameters must be configured from the front panel switches. Parameters that have no front panel control will be set to a default value. The Local switches are illustrated in the Front Panel Controls and Indicators section following the 7550 Parameter Table. The Local switches are inactive when the Remote/Local switch is in the Remote position.

In the Remote mode, Avenue module parameters can be configured and controlled from one or both of the remote control options, the Avenue Touch Screen or the Avenue PC Application. Once the module parameters have been set remotely, the information is stored on the module CPU. This allows the module to be moved to a different cell in the frame at your discretion without losing the stored information.

For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC Remote Configuration section of this document.

For setting the parameters remotely using the Avenue Touch Screen option, refer to the Avenue Touch Screen Remote Configuration section of this document following Avenue PC.

For setting the parameters remotely using the Avenue Express Control Panel option, refer to the Avenue Express Control Panel data pack that comes with the panel option.

Configuration Summary

This section provides a general overview of the configuration for the 7550 module. The controls available for configuration with remote control are summarized and tips and examples are given for using particular controls to achieve the best results.

Video Processing

The 7550 has a full-featured Proc Amp for adjustment of every signal parameter. Proc controls adjust the overall video signal. A Legalizer menu allows adjustment of black and white clips to prevent excessive signal excursions or the output can be set to meet default RGB values determined on a pixel by pixel basis.

The available video/color processing and video timing and output remote control menus are summarized below:

• Proc: Video Gain, Chroma, Pedestal and Hue are standard Proc Amp controls affecting the entire signal. The Hue control gives phase rotation of the color vectors in the manner of an NTSC composite Proc Amp.

• Clip: The Clip menu provides enabling of a Legalizer which insures signal levels will not exceed those permitted in the composite domain. Thus its use can insure a television transmitter will not be presented illegal video input. If set to Off or set for Legal RGB, adjustments are grayed out and may not be changed. When set to Y, Cr, Cb, controls for black and white clipping and chroma limiting are provided.

• Timing: The 7550’s comprehensive range of timing allows complete flexibility in placement of the output picture relative to the applied reference input. A Frame Synchronizer can be enabled to allow timing the signal to an external house reference. Frame Delay can be set for up to three frames of delay.

• Video Out: The Bypass selection takes the 7550 Proc Amp out of the video path by routing the signal around it to the output. One of four internally generated test signals may be selected to be sent to the output signal if needed. Embedded Audio is removed from the SDI stream when Strip is selected in the Strip Audio window. There are Wide, and Narrow vertical blanking choices. Wide gives blanking through line 20 (NTSC) or line 22 (PAL), while narrow produces blanking through line 9 (NTSC) or Line 6 (PAL) of both fields.

• Trims: Cb and Cr offsets allow black balance to be corrected while Cb and Cr gains permit trimming of levels on these two axes. Y/C delay allows the operator to correct inaccuracy of timing of color information relative to luminance. These trims are functional regardless of the input or output formats in use.

• Memory: Up to five configurations of the 7550 may be saved into memory registers for later recall. All parameters – gains, input format, filters, blanking, etc. – and are saved in each memory. The 7550 can be used with the 8415 submodule for audio disembedding, channel swapping and re-embedding in a particular application. In another application other audio parameters can be adjusted for a particular configuration. These two setups could be stored in memory registers and one or the other recalled for instant restoration of the required configuration.

7550-8

Model 7550 HD Video Proc Frame Sync

8415 Audio Processor Configuration

The 8415 Audio Processor accepts audio from the AES input connectors and can disembed audio from the incoming HD or SD SDI video stream.

Between the input and output is a 8x8 mixer with tracking audio delay. Any incoming audio can be mixed, level controlled and/or shuffled to another output channel by means of the integrated audio router. The tracking audio delay allows synchronization and timing to be maintained with time base corrected video passing through the video frame synchronizer of the 7550.

A built in sample rate converter allows use of asynchronous AES input signals. The Audio Processors also support encoded audio formats such as AC-3 and Dolby-E. Because these data streams cannot tolerate sample rate conversion, they must be input to the Audio Processors synchronous to the video. All audio processing is performed at the full 24 bit resolution of the system. At the output side of the submodule the eight audio channels may be simultaneously routed to AES output connectors while also being embedded on the outgoing SDI video. An adapter is also available to allow the AES I/O to be converted from BNC to 110 ohm balanced on the output.

The available audio processing remote control menus are summarized below:

• Audio Mix: This menu gives full access to the 8x8 audio mixer controls. Any input channel can be routed to any or all output busses. Sliders in Avenue PC or rotary knobs on a control panel permit levels to be adjusted from -70dB to +12dB. Alternatively a value can be put in the numeric window, followed by the Enter key, and this will become the new gain setting. Default buttons are provided for return to zero level.

The Tie function is used for stereo operation where gain of a pair of channels is usually desired to be the same. An invert selection allows inversion of a channel to permit phase correction.

• Audio In: Status indicators show presence of AES and embedded (HD SDI or SD SDI) audio inputs. The Audio In A and Audio In B menus allow selection of inputs to the audio mixer. The choices for the 8415 are AES 1/2, AES 3/4, AES 5/6 and AES 7/8 and SDI 1/2, SDI 3/4, SDI 5/6, and SDI 7/8. Thus any pair of input audio signals can be routed to either pair of input buses of the output audio mixer.

• Audio Mode: The Audio Mode control is provided to allow an SDI input with embedded audio to operate in Audio (normal) or Data (non-audio). The 7550 can handle both types of content present in AC-3 or Dolby E signals. Some synchronizing requirements are necessary for supporting these protocols.

Select the Audio mode when the input audio signal is a standard audio signal carrying two channels of linear audio. No special timing requirements are needed in this mode.

Use the Data mode when the serial digital audio is a non-audio, or data, signal. Some special synchronizing requirements must be observed in this mode as described in the following examples.

HD or SD SDI Signal with embedded data – For this case, if an SDI signal with embedded data is applied to the input, the content will be handled by passing through the 7550 frame store memory to the output of the 7550. No audio submodule is required. The audio input signal in this

7550-9

Model 7550 HD Video Proc Frame Sync

case is synchronous to the timing reference. This is normal operation of the 7550 and no special configuration is necessary.

Data mode signal to be disembedded and output as an AES stream – This mode requires the use of an audio submodule to disembed the de-serialized SDI input and route the channels to the correct path. If one of the channels is normal audio, it can be mixed, swapped, shuffled, and delayed by the audio submodule. If the other channel is non-audio data, it bypasses the normal audio functions and is carried to the AES output formatter and driver.

When in the Data mode, the AES formatter is driven by the output timing of the 7550, the original SDI input must be synchronous to the reference input or the 7550 must be configured to use the SDI signal as the timing reference.

Data mode signal to be disembedded, output as AES, then reembedded – In this case the audio submodule is also required. This case is

similar to the one above, while the disembedded data is re-embedded in the SDI output of the 7550. The same timing requirements apply.

Original embedded data to be left unchanged with an additional embedded group to be added – The original embedding in the SDI input

passes through the 7550 processing path. At the same time, an audio submodule is used to create a second embedded group which is placed in cascade, following the original audio group which contains the data mode signal.

A data mode signal in AES format is input to the audio submodule – This example could be used when there is a need to embed the AES data into the output of the 7550. In this case the AES data input must be synchronous. When being used in this manner, the audio submodule can embed data mode AES into one pair of channels in an embedded group, while embedding conventional audio into the other pair.

• Audio Delay: With the Auto Track switched On, audio will be delayed the same

amount as the video passing through the 7550 frame synchronizer thus preserving lip sync. If incoming audio is early due to signals passing through an upstream frame sync without a compensating audio delay, Bulk Delay can be used to correct the problem. Up to 1000 mS of fixed delay can be added to compensate for upstream timing errors.
