Claim:
1. An encoding device performing an encoding process according to an encoding scheme using a Composition Time Stamp (CTS) indicative of a time at which presentation or reproduction is performed, comprising: an encapsulation circuit configured to generate a media unit in which one or more access units encoded by the encoding scheme are capsulated, and a transmitter configured to transmit the media unit and a set of information along with the media unit, the set of information being indicative of an absolute time of one of the one or more access units encapsulated at a top portion of the media unit, transmitter being configured to transmit the set of information as a signal separate from the media unit, wherein the encapsulation circuit is configured to add a CTS relative value to a first access unit encapsulated in the media unit, the CTS relative value being a difference between a CTS assigned to the first access unit and a CTS assigned to a second access unit immediately succeeding the first access unit in presentation in order for a decoder to decode the one or more access units using the absolute time and the CTS relative value to perform presentation or reproduction at the CTS.
