ABSTRACT:
A digital motion video processing circuit can capture, playback and manipulate digital motion video information using the system memory of a computer as a data buffer for holding compressed video data from the circuit. The system memory may be accessed by the circuit over a standard bus. A controller in the circuit directs data flow between an input/output port which transfer a stream of pixel data and to the standard bus. The controller directs data to and from either the standard bus or the input/output port through processing circuitry for compression, decompression, scaling and buffering. The standard bus may be a peripheral component interconnect (PCI) bus. The motion video processing circuit has a data path including pixel data and timing data indicative of a size of an image defined by the pixel data. The timing data is used and/or generated by each component which processes the pixel data, thereby enabling each component to process the pixel data without prior knowledge of the image format. By having processors for handling two compression formats for motion video data connected to this data path, conversion between compression formats, such as between MPEG to Motion JPEG, can be performed.
