Patent ID: 7266291

Claim:
A method for processing audio/video data within an audio/video disk drive comprising a reception interface for receiving a digital audio/video disk containing data compressed according to at least one of a first compression standard and a second compression standard, the second compression standard having a compressed data rate less than a predetermined data transfer rate and having a decoded data rate greater than the predetermined data transfer rate, the method comprising: transferring compressed data from the digital audio/video disk to an electronic chip connected to the reception interface, the electronic chip comprising main processing means for decoding the data if compressed according to the first compression standard, and an input/output interface supporting the predetermined data transfer rate, and if the data is compressed according to the second compression standard, then the electronic chip transfers the data through the input/output interface; and receiving the transferred data by auxiliary processing means connected to the input/output interface, the auxiliary processing means performing the following decoding the data according to the second compression standard, re-encoding the decoded data according to the first compression standard, and transferring the re-encoded data to the electronic chip for decoding according to the first compression standard.
