Claim 2:
3. The method of claim 1, wherein each stream is encoded with EAAC Plus, and said time aligning the packets is performed by estimating the time instance for an (i+l)th frame in the stream by keeping a cumulative estimate of the total number of raw data blocks till the ith frame as follows:, total_number
