Method and apparatus of processing digital broadcasting signal including transmission ensemble number fields in transmitter and receiver

摘要

According to one embodiment, a method of processing a digital broadcasting signal in a transmitter includes: performing RS (Reed-Solomon) encoding on signaling data containing cross layer information between a physical layer and a upper layer; interleaving the RS encoded signaling data, wherein interleaving the RS encoded signaling data includes writing the RS encoded signaling data row-by-row from left-to-right and top-to-bottom in a signaling data block, and outputting the signaling data in the signaling data block by reading column-by-column from top-to-bottom and left-to-right; and transmitting the digital broadcasting signal including the mobile service data and the interleaved signaling data during slots.

1. A method of processing a digital broadcasting signal in a transmitter, the method comprising,
performing RS (Reed-Solomon) encoding on signaling data containing cross layer information between a physical layer and a upper layer; interleaving the RS encoded signaling data, wherein the interleaving the RS encoded signaling data comprises:
writing the RS encoded signaling data row-by-row from left to right and top-to-bottom in a signaling data block; andoutputting the signaling data in the signaling data block by reading column by column from top-to-bottom and left-to-right, wherein the signaling data includes a first field indicating a protocol version change of the signaling data, a second field indicating a length of an extension field of a header included in the signaling data, a first transmission ensemble number field indicating a number of ensembles for a first transmission mode, and a second transmission ensemble number field indicating a number of ensembles for a second transmission mode, and wherein the ensembles include a collection of services, each of the services being a package of packetized streams of mobile service data; transmitting the digital broadcasting signal including the mobile service data and the interleaved signaling data during slots, wherein the first transmission mode is a mode in which the mobile service data are transmitted while reserving greater than 118 packets out of 156 packets in a slot and the second transmission mode is a mode in which the mobile service data are transmitted while reserving less than or equal to 118 packets out of 156 packets in the slot, wherein the second field is also used to skip the first transmission ensemble number field by a receiver for the second transmission mode.
