Method and apparatus for processing MPEG media transport protocol packets

摘要

Disclosed herein are a method and apparatus for processing MMTP packets. When an MMTP packet is transmitted, the packet processing apparatus calculates a reference value from partial field values of a reference MMTP packet header, and inserts the calculated reference value into the compressed header. By the reference value, MMTP packets may be correctly distinguished and may be correctly referred to when there are two reference MMTP packets in which the lower 5 bits of packet sequence numbers are identical to each other, or even when the number of reference MMTP packets is a multiple of 256.

1. A method for processing Moving Picture Experts Group (MPEG) Media Transport Protocol (MMTP) packets, the method being performed by an MPEG media transport sending entity, the method comprising:
calculating a reference value using partial field values of a reference MMTP packet header so as to refer to a reference MMTP packet; generating a reduced size header including the reference value as a field; and generating a compressed MMTP packet including the reduced size header, wherein calculating the reference value comprises calculating the reference value by applying a checksum algorithm to the partial field values of the reference MMTP packet header.
