Patent ID: 7480296

Claim:
Method for generating a multiplexed signal (PS), comprising the following steps: a1) digitizing and coding an audio signal to provide an elementary audio stream (EAS); a2) digitizing and coding a video signal to provide an elementary video stream (EVS); b1) dividing the elementary audio stream (EAS) into prepackets ( 70 A) comprising a header ( 72 ) and a data portion ( 71 ); b2) dividing the elementary video stream (EVS) into prepackets ( 70 V) comprising a header ( 72 ) and a packet data portion ( 71 ); c) merging said packetised elementary streams into one single stream; d) finishing the prepackets ( 70 A; 70 V) such as to form packets ( 70 A; 70 V) by filling-in ESDF data in at least one data field of the header ( 72 ) of each prepacket ( 70 A; 70 V); wherein said ESDF data is derived from the elementary streams (EAS; EVS) before the packetising step (b1; b2), and is communicated to the finishing step (d).
