The 7930 module 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 7930 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. When converting from 59.94 to 23.98 formats, the 3:2 cadence of any existing film material in the input is automatically detected and backed out.
The 7930 can be configured to continually output your facility’s preferred HD format. Just connect any HD signal to the input and the 7930 will cross convert it to the appropriate format for output. And, if the8415 audio option is installed, the audio will automatically be processed as well.
The 7930 can be configured locally or controlled and configured remotely with Avenue Touch Screens, Express 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 7930 converts this caption data transparently between video standards and formats.
Automatic Aspect Ratio Conversion
The 7930 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 downconversion process to adapt automatically to material that is already in letterbox or pillarbox form in order to produce the most appropriate conversion.
When an audio sub module is installed, audio is automatically delayed as needed to compensate for the video processing in the 7930. For complete audio processing, choose from three different audio sub modules. Sub modules plug onto the 7930 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.
