Broadcasting signal transmitting apparatus, broadcast signal receiving apparatus, and broadcast signal transceiving method in a broadcast signal transceiving apparatus

摘要

Disclosed is a broadcast signal transmitting apparatus, a broadcast signal receiving apparatus, and a broadcast signal transceiving method in a broadcast signal transceiving apparatus. The broadcast signal transmitting method comprises the following steps: compressing the headers of data packets of an IP stream identified by IP address information, wherein the compressed data packets include a first packet, the header of which contains static field information, a second packet, the header of which contains dynamic field information, and a third packet, the header of which contains the compressed static field information and/or the compressed dynamic field information; signaling IP-PLP mapping information for mapping the IP stream and a component PLP for transmitting the IP stream, the IP stream compression information, and the header information of the first packet to L2 signaling information; and transmitting the header information of the second and third packets via the component PLP, and transmitting the L2 signaling information via a common PLP.

主权项

1. A method of transmitting broadcast signals, the method comprising:
compressing each header of data packets included in an IP Stream (Internet Protocol Stream), the IP Stream being identified by IP address information, wherein the data packets with the compressed headers comprise a first packet having a header including a static field information, a second packet having a header including a dynamic field information, and a third packet having a header including at least one of a compressed static field information and a compressed dynamic field information; building a signal frame including a plurality of PLPs (Physical Layer Pipes), wherein the signal frame includes IP-PLP mapping information for establishing a link between the IP Stream and a PLP transmitting the IP Stream, compression information of the IP Stream, wherein each of the plurality of PLPs carries at least one component of the IP Stream; and transmitting the built signal frame, wherein header information of the second and third packets are transmitted through the plurality of PLPs.
