Abstract
A broadcast receiving apparatus and a signal processing method thereof are provided. The broadcast receiving apparatus includes a receiver configured to receive a data stream comprising a plurality of physical layer pipes (PLPs); a demodulator configured to output at least one generic packet corresponding to each of the plurality of PLPs and additional information on the at least one generic packet by demodulating the plurality of PLPs; and a signal processor configured to process the at least one generic packet based on the output additional information.
Claims16
A broadcast receiving apparatus comprising:
- a receiver configured to receive a data stream comprising a plurality of physical layer pipes (PLPs);
- a demodulator configured to output at least one generic packet corresponding to each of the plurality of PLPs and additional information on the at least one generic packet by demodulating the plurality of PLPs;
- and
- a signal processor configured to identify the at least one generic packet based on identification information of each of the plurality of PLPs included in the additional information and process the identified generic packet,
- wherein the additional information comprises time information comprising information on a time when the data stream is received and information on a time required for demodulating the at least one generic packet, and
- wherein the signal processor is configured to identify whether the time information is valid based on valid information included in the additional information and output data corresponding to the at least one generic packet based on a result of the identification.
A signal processing method of a broadcast receiving apparatus, the method comprising:
- receiving a data stream comprising a plurality of physical layer pipes (PLPs);
- outputting at least one generic packet corresponding to each of the plurality of PLPs and additional information on the at least one generic packet by demodulating the plurality of PLPs;
- identifying the at least one generic packet based on identification information of each of the plurality of PLPs included in the additional information;
- and
- processing the identified generic packet,
- wherein the additional information comprises time information comprising information on a time when the data stream is received and information on a time required for demodulating the at least one generic packet, and
- wherein the processing comprises:
- identifying whether the time information is valid based on valid information included in the additional information;
- and
- outputting data corresponding to the at least one generic packet based on a result of the identification.
