Encoding apparatus and the method

摘要

An encoding apparatus adds delay time information DTI indicating initial delay time i_d and delay time d of each group data to a position to be read prior to frame data by a decoding apparatus in the group data of encoding stream data DBI and transmits the same to the decoding apparatus 3. Namely, the encoding apparatus does not transmit initial offset delay time i_of to the decoding apparatus 3. The encoding apparatus starts to read and transmit the encoding stream data DBI from a transmission buffer at a predetermined bit rate R at timing designated by the initial offset delay time i_of.

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.
