PROCEDURE AND APPARATUS FOR PROCESSING AUDIO INFORMATION USING ALLOCATION BLOCKS IN AUDIO TIME CODED IN VIDEO / AUDIO APPLICATIONS TO FACILITATE AUDIO SWITCHING.

摘要

A method for processing audio information comprising: - receiving an input audio signal that carries said audio information - receiving video frame references indicating the time references of a sequence of video frames, - generating information blocks of encoded audio from said audio information in a reduced bit rate format by applying a block coding process to said input audio signal and time compression of said encoded audio information blocks, and - joining said compressed blocks in time in an encoded audio train comprising a plurality of sequences of said compressed blocks in time so that an initial block of a given sequence is separated from a final block of a previous sequence by a separation which is aligned in time with a respective video frame reference.
