The present invention relates to an apparatus and method for transmitting a packet and to an apparatus and method for receiving a packet in an MMT system. A packet transmission apparatus for transmitting a packet in an MPEG media transport (MMT) system may comprise an encapsulation unit which performs an encapsulation including the information relating to whether the time interval between composition time stamps (CTSs) of all of consecutive access units (Aus) in a media processing unit (MPU) is constant so as to encapsulate the media processing unit. Thus, the amount of timing information which may be contained within one media processing unit is reduced to increase the space practically used in data transmission, thereby improving the transmission efficiency. |
