ABSTRACT:
First and second input data sequences are packetized to produce packets having fixed first and second lengths, respectively. A flag and headers are attached to the packets for transmission. In a demultiplexing apparatus, when the header cannot be properly identified, subsequent demultiplexing steps are performed by estimating that the subsequent data is the first input data sequence, when the first length occurs before the next flag, and estimating that the subsequent data is the second input data sequence, when the second length occurs. When the flag cannot be properly identified, the flag is expected at the first length from the previous header when the previous header indicates the first input data sequence, and the flag is expected at the second length when the previous header indicates the second input data sequence.
