ABSTRACT:
A method and apparatus for scalably decoding a sequence of encoded digital video frames with a digital processor. A frame discard interval is determined in accordance with the processing power of the digital processor and a counter is initialized. A frame is selected from the sequence for decoding. The selected frame is decoded and the counter is incremented. If the counter is less than the discard interval then the process is repeated; otherwise, at least one subsequent frame from the sequence is replaced with a sync frame which is thereafter decoded.
