Abstract
A digital broadcasting system for transmitting/receiving a digital broadc asting signal and a data processing method are disclosed. A program table in formation has an identifier identifying mobile service data and main service data in a broadcasting signal. The program table information is mulitiplexe d with the mobile service data and main service data. Then, broadcast receiv ing system can receive and output the mobile service data by parsing the pro gram table information and using the identifier.
Claims (18)
- [1] A data processing method comprising:
multiplexing program table information, which describes main service data and mobile service data and includes an identifier for identifying the main service data and the mobile service data, with the mobile service data and the main service data;
performing an error correction encoding process with respect to the multiplexed mobile service data and multiplexing the mobile service data, which is subjected to the error correction encoding process, and the multiplexed main service data to output data packets; and odulating and transmitting the data packets. - [2] The data processing method according to claim 1, wherein, when the program table information is at least one of a virtual channel table (VCT) and a program map table (PMT), the identifier is a modulation_mode field value in the program table information.
- [3] The data processing method according to claim 1, wherein, when the program table information is at least one of a virtual channel table (VCT) and a program map table (PMT), the identifier is a service_type field value in the program table information.
- [4] The data processing method according to claim 1, wherein, when the program table information is a virtual channel table (VCT), the identifier is included in service_location_descriptor.
- [5] The data processing method according to claim 1, wherein, when the program table information is a program mapping table (PMT), the identifier is included in a descriptor of the PMT.
- [6] The data processing method according to claim 1, wherein the modulating and transmitting the data packets includes:
arranging the data packets in an unit of a data group and interleaving the data packets by the unit of the data group;
outputting a broadcasting signal obtained by modulating the interleaved broadcasting data; and transmitting the output broadcasting signal. - [7] A data processing method comprising:
receiving a broadcasting signal in which main service data and mobile service data are multiplexed in an unit of a data group;
obtaining program table information, which describes the main service data and the mobile service data and includes an identifier for identifying the main service data and the mobile service, from the received broadcasting signal; and parsing the obtained program table information and decoding the mobile service data using the parsed program table information. - [8] The data processing method according to claim 7, wherein the broadcasting signal includes the mobile service data and the main service data interleaved by the unit of the data group.
- [9] The data processing method according to claim 7, wherein, when the program table information is at least one of a virtual channel table (VCT) and a program map table (PMT), the identifier is a modulation_mode field value in the program table information.
- [10] The data processing method according to claim 7, wherein, when the program table information is at least one of a virtual channel table (VCT) and a program map table (PMT), the identifier is a service_type field value in the program table information.
- [11] The data processing method according to claim 7, wherein, when the program table information is a virtual channel table (VCT), the identifier is included in service_location_descriptor.
- [12] The data processing method according to claim 7, wherein, when the program table information is a program mapping table (PMT), the identifier is included in a descriptor of the PMT.
- [13] A digital broadcasting system comprising:
a tuner receiving a broadcasting signal in which main service data and mobile service data are multiplexed in a unit of a data group;
a demodulator demodulating the main service data and the mobile service data from the broadcasting signal received by the tuner and outputting the de-modulated data;
a demultiplexer demultiplexing program table information including an identifier for identifying the main service data and the mobile service data, a video stream and an audio stream, in the demodulated data output from the demodulator;
a decoder decoding broadcasting contents according to the demultiplexed video and audio streams;
a program table information decoder decoding the demultiplexed program table information of the mobile service data; and a controller controlling the broadcasting contents to be output according to the decoded program table information. - [14] The digital broadcasting system according to claim 13, wherein the program table information is a PMT.
- [15] The digital broadcasting system according to claim 13, wherein the program table information is a VCT.
- [16] The digital broadcasting system according to claim 15, wherein, when the program table information is a VCT, the identifier is at least one of modulation_mode field value, service_type field value and field value included in service_location_descriptor.
- [17] The digital broadcasting system according to claim 15, wherein the controller controls a channel map to be generated by using channel information included in the main service data and channel information included in the mobile service data in the VCT.
- [18] The digital broadcasting system according to claim 13, wherein the controller controls power of the demodulator such that the demodulator demodulates only a burst section including the broadcasting contents.
