A method of receiving a broadcast signal including a Non-Real-Time (NRT) service and a broadcast receiver are disclosed herein. A method of receiving a broadcast signal including an NRT service, the method comprises receiving a broadcast signal including first signaling information and second signaling information, identifying the NRT service based on the first signaling information, parsing the second signaling information to identify an Internet Protocol (IP) address of an NRT service signaling channel, receiving the NRT service signaling channel by accessing the IP address, and downloading a desired NRT service based on the NRT service signaling channel.

A method of processing channel information and a receiver are disclosed. The receiver includes a first manager, a database, a channel manager, and a second manager. The first manager may receive a packet including service provider discovery information including service provider identification information, and a packet including service discovery information including content provider identification information and content service identification information and extracting the information included in the packets. The second manager may perform a control operation to form multi-part channel information using the identification information and receive a content service of a channel corresponding to the multi-part channel information.

A method of processing broadcast data in a broadcast transmitter includes performing Reed-Solomon (RS) encoding and Cyclic Redundancy Check (CRC) encoding on mobile service data to build at least one RS frame including the mobile service data and dividing the at least one RS frame into a plurality of portions; dividing each of the plurality of portions into several Serial Concatenated Convolutional Code (SCCC) blocks according to SCCC block mode information, encoding data in the SCCC blocks, and mapping the SCCC blocks including the encoded data to data blocks according to the SCCC block mode information; encoding signaling data including fast information channel (FIC) data and transmission parameter channel (TPC) data; and modulating a broadcast signal including data in the data blocks and the encoded signaling data.
摘要:
A method of processing data in an IPTV receiver and such an IPTV receiver are disclosed. The method includes receiving location information necessary to acquire a content corresponding to a content reference identifier (CRID) by using the CRID, requesting an Internet protocol multimedia subsystem Gateway (IG) to transmit a session description protocol (SDP) file of the content, wherein the content is identified by the CRID and an instance metadata identifier (IMI), receiving the requested SDP file from the IG, and controlling a session setup for processing the content by using the received location information and the received SDP file.
摘要:
A digital broadcasting system and a method of processing data are disclosed, which are robust to error when mobile service data are transmitted. To this end, additional encoding is performed for the mobile service data, whereby it is possible to strongly cope with fast channel change while giving robustness to the mobile service data.
