METHOD AND SYSTEM FOR PROVIDING A HIGH SPEED MULTI-STREAM MPEG PROCESSOR

摘要

An MPEG processor is provided (Fig. 2). According to one aspect of the processor, multiple MPEG data streams for corresponding channels are individually stored in an off-chip memory (Fig. 2, item 26). Corresponding data for a channel is then retrieved from the off-chip memory for processing. The retrieved data is then decoded (Fig. 2, item 18). The decoded results and associated information are stored on the off-chip memory. Some or all of the associated information that can be used for decoding subsequent data is stored in an on-chip memory (Fig. 2, item 26). When video images need to be displayed, the corresponding data that is needed for that purpose is then retrieved from the off-chip memory and provided to an analog encoder for encoding in a format that is compatible with an analog display device (Fig, 2, item 24).
