First Claim
1. A method for transmitting a main packet stream generated by multiplexing a plurality of substreams, using a single transmission channel, comprising:
- packeting each of the plurality of substreams and generating substream packets;
allocating substream sequence information to the substream packets according to a sequence in which the substream packets are generated;
allocating main packet stream sequence information to the substream packets according to a sequence in which the substream packets are inputted; and
multiplexing inputted substream packets and generating the main packet stream.
