The 7920 module has an HD SDI input and four outputs that can be configured as two SDI and twocomposite outputs, or four SDI outputs. Whether it’s providing digital feeds to production switchers and routers or analog monitoring, the 7920 is right at home.


The Downconversion process includes Picture Detail Enhancement and Anti-Alias Filtering, which make for a pristine SD output. The Aspect Ratio Conversion process offers Resizing and Repositioning with choices for: Letterbox, Anamorphic, Crop and Zoom. The 7920 automatically adjusts from HD to SD color space and gamma. Proc amp controls are provided in the form of Video, Chroma and Pedestal.


The 7920 can be configured locally or controlled and configured remotely with Avenue Touch ScreensExpress Panels, or Avenue PC Software. Alarm generation, configurable user levels, module lock out, and customizable menus are just some of the tools included in the Avenue control system.



HD closed captioning is carried in data packets in the vertical interval ancillary data space. The 7920 properly translates between HD caption data and traditional SD captioning (line 21 or 23) so that closed captioning content is converted transparently between video standards and formats.


Automatic Aspect Ratio Conversion


The 7920 supports 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 they are read at the 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 Options


When an audio sub module is installed, audio is automatically delayed as needed to compensate for the video processing in the 7920. For complete audio processing, choose from three different audio sub modules. Sub modules plug onto the 7920 board and do not take up a slot in the frame.


The 8415 is an eight-channel audio sub module 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. The 9670 Automatic Gain Control option can be added to the 8415. All audio processing is performed at full 24 bit resolution.


The 7610 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.
