TRANSPORT STREAM PACKETS HEADERS COMPRESSION Russian patent published in 2017 - IPC H04L12/70 H03M7/30 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering. Method of headers compression by a transmission device, wherein a data stream is generated from the transport stream including one or more data packets and one or more NULL packets, herewith the data stream includes only one or more first data packets, each of which has a header, which includes a packet identifier as the first value, and one or more NULL packets, each of which has a header, which includes a packet identifier as the second value; the data stream is compared with the first main stream of the physical level with compression of headers among a plurality of main streams of the physical level comprising a physical level frame; generated are one or more first data packets with compressed headers, one or more NULL packets with compressed headers and information of the packet identifier, herewith the headers compression includes processing for replacement of the packet identifier included in the packet header into a single-bit NULL packet identifier showing whether the packet identified by the packet identifier is a NULL packet.

EFFECT: technical result is improvement of efficiency of transmitting and receiving digital broadcasting data.
