Abstract
Provided is a method and apparatus for multiplexing bitstreams that are coded to have different frame lengths using asynchronous time alignment, in which, based on the length of each frame of a bitstream selected as a reference bitstream from among bitstreams coded to have different frame lengths by a plurality of coders, the remaining bitstreams except for the reference bitstream are divided and multiplexed.
Claims6
A method of multiplexing asynchronous bitstreams, the method comprising:
- selecting a reference bitstream from among bitstreams that are coded to have different frame lengths by a plurality of coders;
- determining a start point of each bitstream;
- dividing a portion of the bitstreams except for the reference bitstream from psm(n) to pem(n), where psm(n) is a pointer indicating a start point for division in the reference bitstream corresponding to the nth frame and the divided bitstream corresponding to the mth frame to be multiplexed and pem(n) is a pointer indicating an end point for division in the reference bitstream corresponding to the nth frame and the divided bitstream corresponding to the mth frame to be multiplexed;
- dividing a portion of the bitstreams except for the reference bitstream from psm+1(n) to pem+1(n), where psm+1(n) is a pointer indicating a start point for division in the reference bitstream corresponding to the nth frame and the divided bitstream corresponding to the (m+1)th frame to be multiplexed and pem+1(n) is a pointer indicating an end point for division in the reference bitstream corresponding to the nth frame and the divided bitstream corresponding to the (m+1)th frame to be multiplexed;
- and
- multiplexing the reference bitstream and the divided bitstreams.
