Abstract
An encoding device performing an encoding process according to an encoding scheme using a CTS indicating time at which presentation or reproduction is performed, comprising: an encapsulator that generates a media unit in which one or more access units encoded by the encoding scheme are capsulated, and a transmitter that transmits information indicating an absolute time of an access unit included at a top portion of the media unit, in addition to the media unit, wherein the encapsulator adds a CTS relative value to the nth access unit included in the media unit, the CTS relative value being a difference between the CTS of the nth access unit and the DTS of the n+1th access unit.
