The 7610 is an 8CH sub module for use with Avenue 7900 series up/down/cross converters. It provides processing for signals with embedded audio. No audio I/O is provided. Audio is disembedder, delayed and then re-embedded into the video stream. All audio processing is performed at full 24 bit resolution by a digital signal processor (DSP). Lip sync preservation has been 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 house. This allows embedded audio to be safely bypassed around the video frame store with lip sync properly preserved.
