MODULE OVERVIEW

The 7900 module is a flexible, configurable up and downconverter for use in broadcast and post-production. It can process SD (Standard Definition) signals into HD, downconvert HD signals into SD, and perform format and aspect ratio conversion on both SD and HD signals. Refer to the functional block diagram for the module on the next page.

The 7900 can be configured to continually output a facility’s preferred HD format. Any HD signal connected to the input will be converted to the correct format for the output. And if the 8415 audio option is installed, the audio will be automatically processed as well.

Upconversion – When configured as an upconverter, the 7900 has an SD SDI input and four HD SDI outputs. Excellent for on-air use, the module is equally at home in an HD island, a signal ingest installation, or in a production application.

The 7900 uses sophisticated edge and motion adaptive noise reduction, ensuring delivery of a pristine output that is excellent for use in broadcast. All processing is performed on progressive signals at full bandwidth 4:4:4 for optimum signal quality. Signals are interlaced and de-interlaced as required with motion adaption and edge interpolation. Aspect ratio conversion choices include: Anamorphic, Pillarbox, Crop, and Manual.

Input standard and frame rate are auto-detected. The 7900 automatically performs 16-bit SD to HD color space conversion. The built-in Proc Amp provides adjustment of signal parameters with controls for Video Gain, Chroma, Pedestal, and Hue. Vertical interval data is faithfully preserved and is passed from SD to HD with several choices for handling the embedded timecode. The upconverted output is timeable with respect to the reference input.

Downconversion – When used as a downconverter, the 7900 has an HD SDI input and four SD SDI outputs. Two of the SD output BNCs can be configured as SD SDI or composite by setting jumpers on the module circuit board.

The downconversion process includes picture detail enhancement and anti-alias filtering which makes for a pristine SD output. The aspect ratio conversion process offers resizing and repositioning with choices for Anamorphic, Letterbox, Crop and Manual. The 7900 automatically adjusts between HD and SD color space and gamma. Proc amp controls are provided in the form of video, chroma, setup, and hue. Both the digital and analog outputs are timeable with respect to the reference input. Composite outputs can be timed into house with proper subcarrier and phase.

Cross conversion – The 7900 provides cross conversion between HD 1.5 Gb/s formats, processing all popular variations of 1080 and 720, making it simple for every facility to ingest any type of HD signal.

All popular variations of 720p, 1080i, 1080sF, and 1080p are supported. The 7900 converts between any HD signals within the 59.94/23.98/29.97 family, within the 50/25 fps family, or within the 60/30 fps family. 3:2 pulldown is used when converting between 59.94 and

23.98. Film mode is automatically detected.

Meta Data – Closed captioning in standard definition is carried in the traditional line 21 (NTSC)/line 23 (PAL) manner, while HD closed captioning is carried in data packets in the vertical ancillary data space. The 7900 properly translates between these two methods so that closed captioning content is converted transparently between video standards and formats.

Automatic Aspect Ratio Conversion – The 7900 supports WSS (Wide Screen Signaling), AFD (Active Format Description) to mark or identify the aspect ratio of the video content. These flags are generated at the output of the module and read at the module input. This allows the up and down conversion process to adapt automatically to material that is already in letterbox or pillarbox form in order to produce the most appropriate conversion.

Audio Submodule Options – Audio is automatically delayed as needed to compensate for the video processing in the 7900 when an audio submodule is installed. For complete audio processing, choose from three different audio submodules that plug onto the main circuit board.

The 8415 is an 8-channel audio submodule with AES I/O that provides management of embedded audio in the processing path, or supports audio embedding /disembedding alongside the video processing elements. Embedded audio is safely bypassed around the video frame store with the lip sync preserved. Level adjustments and channel shuffling are accessed through the built-in audio mixer. All audio processing is performed at full 24-bit resolution by a digital signal processor (DSP).

The 7610 audio submodule provides carriage of up to eight channels of embedded audio through the format conversion process. Embedded audio in the input signal is delayed to match the video delay and preserve lip sync. The delayed content is reinserted in the video output. No level adjustment or channel swapping is provided.

The 7615 audio submodule also provides processing for signals with eight channels of embedded audio. It offers the same processing and AES I/O as the 8415, plus the ability to decode Dolby-E signals.

Configuration And Control

The on-board CPU can monitor and report module ID information (slot location, software version and board revision), power status, and ancillary data status 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.

Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts for the module by on-board regulator. 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 7900 can be configured locally or controlled and configured remotely with Avenue Touch Screens, Express Panels, or Avenue PC Software. Alarm generators, configurable user levels, module lock out, and customizable Virtual Modules are just some of the tools included in the Avenue Control system.

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

SD Upconversion

The 7900 module can be utilized to upconvert SD video from many different source types. As shown in the example below, the SD ingest signal from a satellite is fed to a 7900 module where it is upconverted to feed an HD Master Control Switcher. The other three outputs can be sent to other HD destinations.

In both up and downconversion, the module provides sophisticated adaptive noise reduction for noisy input signals for use in broadcast applications. Timing to a house reference is available on the module, along with many other controls features for ensuring a clean, stable signal.

HD Downconversion

The 7900 module can be utilized to down convert HD video to suit many applications. As shown in the example below, the HD ingest signal from a satellite is fed to a 7900 module where it is down converted to feed an SD Master Control Switcher. The other three outputs can be sent to other SD destinations.

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 7900 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 7900 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 of the remote control options, the Avenue Touch Screen, Avenue Express Control Panel, 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 slot 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.

Express Panel operation is described in the data pack that accompanies the control panel option.
