ABSTRACT:
A method and apparatus for storing a sequence of compressed frames of digital motion video information in a circular buffer is disclosed. In a preferred embodiment, compressed digital motion video information is written from a storage device to the circular buffer. A host pointer is set equal to the location corresponding to the end of the last frame of motion video information written to the circular buffer, and the positions of a microcode pointer and the host pointer are compared. Based on these positions, determinations are made regarding (i) whether a compressed frame of digital motion video information is present in the circular buffer and ready for decompression and (ii) whether a portion of the circular buffer can be re-written with compressed digital motion video data based on the positions of the microcode and host pointers.
