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. It also contains triple transfer buffers for intermediate storage of digital audio data. The system board contains the main CPU, DMA controllers and SCSI interfaces required to perform high speed audio-video data transfers to/from disk. The triple transfer buffers of the present invention include a present buffer, a past buffer and a future buffer, the purpose of which is to ensure that there is sufficient video and audio material in the present buffers to minimize any discontinuities in either the audio or the video channel outputs. The invention provides an E to C mode to allow the user to view video which has been compressed and decompressed to verify that no unwanted system artifacts exist or are being created by the compression process. The viewing of the compressed and decompressed material is done in real-time while the material is being compressed and stored. Under software control, a user may bypass the compression circuit and capture uncompressed still frames directly in the triple transfer buffer, and store the uncompressed still frames, thereby permitting the independent display of still and motion video in each respective output channel.
