  • Patent number: 6092119
    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.
