Compressed-data processing arrangement and related method
First Claim
1. A compressed-data processing arrangement comprising buffer means for receiving a stream of compressed data and de-multiplexing means for retrieving navigation information embedded within the compressed data, characterised in that the said buffer means comprises a common buffer and further including pointer memory means for storing a plurality of pointers arranged to identify sectors of data in the said common buffer for the onward delivery of data to decoding means.
