ABSTRACT:
A decoder for audio signals belonging to audio-visual streams coded in accordance with standard ISO/IEC 11172 is provided. The decoder has a presentation unit (UP) which is controlled by a first and a second clock signal, depending on the desired sampling rate, and is associated to device for (SAV) managing audio-video synchronization. The latter device starts the presentation of output data by comparing a first timing signal (SCR), representative of a system clock signal, and a second timing signal (PTS), representative of a correct instant of data presentation, independently generate the two clock signals (CLK24, CLK22) and corrects the signal corresponding to the desired sampling rate with the use of a feedback circuit which includes a digital filter (FD).
