METHOD AND APPARATUS FOR PROCESSING SIGNALING DATA BETWEEN LAYERS IN IP-BASED DIGITAL BROADCASTING SYSTEM

摘要

In one embodiment according to, IP (Internet Protocol) based on the digital broadcasting transmitter of the present invention, a method for processing signaling data contained in at least one protocol layer, the layer (N + M) according to the protocol, the step of copying the signaling data contained in the layer (N + M) packets, that the copied signaling data length which identifies the length of the copy signaling data field and the copy signaling data is present by inserting a pointed signaling indicator to the end of the layer (N + M) the payload of the packet, generating the layer (N + M) packet, according to a protocol of a layer (N + L), layer (N + L ) header, and generating a layer (N + L), a packet including the layer (N + M) packet, according to a protocol of a layer (N), layer (N) header and the layer (N + L) packets generating a layer (N) packet including, where the layer (N) header includes an indicator field that identifies that contains the signaling indicator to the layer (N) packet; And treated according to the protocol of the physical layer to the layer (N) packet, generating a broadcasting signal.
