Abstract: A random access audio/video processor having multiple outputs is disclosed. The processor includes a main control unit with analog video and audio back panels, an analog input/output board, audio and video processing boards, video effects board, synchronization board, and a system board (containing the main CPU). The video processing board includes a compressor for compressing input video signals, and triple transfer buffers for intermediate storage of digital video path. The video processing board further includes decompression circuits coupled to each of two triple transfer buffers for decompressing compressed stored video, and providing the decompressed video channels to an effects board for the addition of special effects. The audio processing board contains processors for compression, decompression, and effects, as well as triple transfer buffers. The triple transfer buffers include present, past, and future buffers which jointly operate to minimize discontinuities in the output channels.

Abstract: A random access audio/video processor having multiple outputs is disclosed. The random access audio/video processor includes a main control unit having an analog video back panel, an analog audio back panel, an analog input/output (I/O) board. An audio processing board, a video processing board, a video effects board, a syncronization board, and a system board (containing the main CPU). The video processing board includes a compressor for compressing input video signals, and a triple transfer buffer, for intermediate storage of digital video path. The video processing board further includes decompression circuits coupled to each of two triple transfer buffers for decompressing compressed stored video, and providing the decompressed video channels to an effects board for the addition of special effects. The audio processing board contains four digital signal processors for audio compression, decompression, and effects processor.
