Claim Text:
1. A decoding method comprising steps of: receiving a plurality of bit streams, each of the plurality of bit streams including delay information indicating delay time from providing a respective bit stream to a decoder buffer until providing the respective bit stream from the decoder buffer, the delay information being included in a group of data included in the respective bit stream, and the delay time being set individually for each of a plurality of frames in the group of data included in the respective bit stream by an encoder from which the respective bit stream and the respective delay information is received; controlling delay time from providing the plurality of bit streams to the decoder buffer until decoding the plurality of bit streams according to at least the delay information; and decoding the plurality of bit streams using a single decoder by preferentially decoding one of the plurality of bit streams before another of the plurality of bit streams with the single decoder based upon the delay information, wherein the delay time is set by the encoder based on a reference time at which a first frame of the group of data included in the respective bit stream is provided from an encoder buffer.
