TRANSPORT STREAM PACKET HEADER COMPRESSION Russian patent published in 2014 - IPC H04L12/70 H04N21/236 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. The method of transmitting a data stream in a physical layer frame in which data packet groups are mapped in a plurality of physical layer trunk streams, wherein the plurality of physical layer trunk streams include one or more physical layer trunk streams with header compression, to which only one group of data packets is mapped; the method involves generating packet identifier information and a group of data packets with compressed headers from a group of data packets mapped to the physical layer trunk stream with header compression, wherein a data packet with a compressed header has a compressed header with a remote packet identifier, wherein the packet identifier information indicates a single value of the packet identifier from a group of data packets mapped to said physical layer trunk stream with header compression; and transmitting the physical layer frame which includes packet identifier information and the group of data packets with compressed headers, for each of the physical layer trunk streams with header compression.

EFFECT: high efficiency of transmitting and receiving digital broadcast data.
