5230 and 6230 OVERVIEW

The 5230 takes serial digital component and converts the signal into either composite or component analog video outputs. 8x oversampling and 12 bit processing ensure high quality conversion for use in the most demanding applications.

The 5230 has a full-featured Proc Amp for adjustment of every signal parameter. Proc controls include video and chroma gain, NTSC style hue rotation, black balance, and pedestal.

Selective (toothed) vertical blanking lets you choose to pass or strip content in the vertical interval on a line by line and field by field basis.

The output timing of the 5230 is fully adjustable relative to the reference input signal. Composite outputs can be precisely color-timed and will also track color framing of the reference signal. Incorporating a full frame synchronizer, the 5230 accepts serial inputs that are asynchronous to the reference.

The 6230 is an optional audio submodule for disembedding or converting. This audio processor option has AES audio inputs and analog outputs, and the ability to disembed audio from the serial digital video stream. Disembedded audio or signals from any of the inputs may be mixed, shuffled or level controlled and any of the channels re-embedded and/or sent to the analog output connectors.

Full audio delay tracking is included as well as the provision to add fixed delay to correct incoming lip sync errors. There is built-in sample rate conversion allowing use of asynchronous AES inputs, while synchronous AC-3 or Dolby-E audio signals may also be used. As always, the comprehensive Avenue control system allows for monitoring and adjustment of all parameters through networked Touch Screen or PC control.

Other features include the following:

• Clips and chroma limiting

• Composite legalizer

• Internal color bars test generator

Power is derived from the ± 12 volt frame power. It is regulated to the required + 5 volts for the digital circuitry and ± 8 volts for the analog circuitry by on-board regulators. The module is fused with a resettable fuse device. If the fuse opens due to an overcurrent condition, the module will lose power. After pulling the module, the fuse will reset automatically requiring no replacement fuse.

The on-board CPU can monitor and report module ID information including slot location, software version and board revision and other data to the optional frame System Control module. This information can be accessed by the user or set to register an alarm if desired using the remote control options available.

Every function and parameter on the 5230 module can be controlled from an Avenue Touch Screen Control 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.

APPLICATIONS

This section provides some typical applications for utilizing the full versatility of the 5230 Video Processor module and the optional submodule, the 6230 Audio Processor.

Video Server Feeding an Analog Switcher

As illustrated in the block diagram below, the 5230 accepts a serial digital video input with embedded audio from a video server. The digital video will be converted to composite analog and fed to an analog switcher. The embedded audio in the serial digital stream will be disembeded and converted to analog audio outputs in the 6230 submodule.

Proper audio/video timing can be assured when the tracking audio delay of the 6230 Audio Processor is employed. Any timing or delay modifications to the video are tracked by the 6230 whether you wish to use disembedded audio or audio input from an AES source. Properly timed audio from any of these sources is available directly when routed to the analog audio outputs. A fixed delay of up to 1000 mS can be inserted by the 6230 to correct for signals which have previously passed through frame stores without audio delay compensation.

INSTALLATION

6230 Submodule Installation

The optional 6230 Audio Processing submodule installs on the component side of the 5230 Video Processing module circuit board. If the option is ordered with the 5230 module, it will come already installed.

To install the 6230 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.

5230 Video Processing Module

Plug the 5230 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 5230/6230 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 5230/6230 Parameter Table.

Avenue module parameters can be configured and controlled remotely 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. Remote configuration will override whatever the switch settings are on the front edge of the module.

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.

Configuration Summary

This section provides a general overview of the configuration for the 5230 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 5230 has a full-featured Proc Amp for adjustment of every signal parameter. Proc controls include video and chroma gain, NTSC style hue rotation, black balance, and pedestal. Black and white clips can be set to prevent excessive signal excursions.

Certain values represented in serial digital component may be illegal in the NTSC or PAL composite domains. The Predictive Composite Clipper mode identifies picture elements that would be illegal in analog composite, and limits color saturation and luminance excursions. You can be confident that the work you’re doing in digital component will look its best in composite.

Selective (toothed) vertical blanking lets you choose to pass or strip content in the vertical interval on a line by line and field by field basis.

5230/6230-8

Model 5230/6230 Video Audio DAC

The 5230 has analog composite or analog component outputs. They are fully timed to your house reference, including the subcarrier and ScH phase of the composite output. The analog output is constructed at 8x oversampling with 12 bits of quantizing resolution.

The available video processing remote control menus are summarized below:

• Proc Menu: Gain, Chroma, Pedestal and Hue are standard Proc Amp controls. Even though the input is SDI, the Hue control gives phase rotation of the color vectors in the manner of an NTSC composite Proc Amp.

• Clip: The Legalizer is a predictive clipper 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 Off or Legal are selected other adjustments are grayed and may not be changed. While Legal automatically puts in values to insure signals will not exceed composite legal limits, selecting Custom allows the operator to insert a range of clip values.

• Timing: The 5230’s comprehensive range of timing allows complete flexibility in placement of the output picture relative to the applied reference input. Fine Phase and Hor Timing take the horizontal timing across the entire line with nanosecond accuracy. A Vert Timing adjustment completes the range in allowing any output timing desired by the operator.

• Status: This dynamic monitoring display provides indicators of video and audio inputs and EDH error status. The 6230 will show in the Option window when present.

• Trim: 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.

• Blanking: There are Wide, Narrow or Custom 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. In the Custom mode any individual lines from 9 through 23 may be selectively blanked, with different choices allowed for each field. Some systems recognize position of the V-bit to control end of blanking. In the 525 standard V-bit position can be set to line 10, line 20 or line

23. In 625 mode V-bit is fixed at line 23 as this is the only position permitted by the 625 Standard.

• Memory: Up to five configurations of the 5230 may be saved into memory registers for later recall. All parameters – gains, input format, filters, blanking, etc. - are saved in each memory. The 5230 can be used with component analog outputs in a particular application. In another application it is used with composite input, noise reduction and embedding of audio from an analog audio input source. These two setups could be stored in memory registers and one or the other recalled for instant restoration of the required configuration.

5230/6230-9

Model 5230/6230 Video Audio DAC

6230 Audio Processor Configuration

The 6230 Audio Processor will accept audio from the AES input connectors and can disembed audio from the incoming SDI video stream. Between the input and output is a 4x4 audio 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 5230.

A built in sample rate converter allows use of asynchronous AES input signals. The 6230 also supports encoded audio formats such as AC-3 and Dolby-E. All audio processing is performed at the full 24 bit resolution of the system. At the output side of the 6230 submodule the four audio channels are routed to analog output connectors. An adapter is also available to allow the AES I/O to be converted from BNC to 110 ohm balanced.

The available audio processing remote control menus are summarized below:

• Audio In: Status indicators show presence of AES and embedded (SDI) audio

inputs. The In 1/2 Sel and In 3/4 Sel controls provide for selection of inputs to the 4x4 audio mixer. The choices for each are AES 1/2, SDI 1/2, AES 3/4, and SDI 3/4. Thus any pair of input audio signals can be routed to either pair of input buses of the 4 input 4 output audio mixer. This allows full flexibility of audio routing.

• Audio Mix: This menu gives full access to the 4x4 audio mixer controls. Any input

channel can be routed to any or all output busses. Sliders or Touch Screen rotary knobs 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 Delay: With the Auto Track switched On, audio will be delayed the same

amount as the video passing through the 5230 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.
