Abstract
A broadcast receiving for updating service map information by scanning the broadcast signal when signaling information included in a broadcast signal has been changed.
Claims19
A broadcast receiving apparatus comprising:
- a memory;
- a receiver configured to receive a broadcast signal, the broadcast signal comprising data of a plurality of channels and signaling information;
- a processor configured to process the broadcast signal, the processor configured to:
- perform a scanning operation with respect to a plurality of frequency bands of the broadcast signal,
- store service map information with respect to the plurality of frequency bands in the memory based the scanning operation, wherein the service map information is configured to be used to tune the plurality of channels,
- identify whether the signaling information, for tuning to one channel of the plurality of channels, included in the service map information stored in the memory is valid based on the broadcast signal currently received by the receiver, and
- in response to identifying that the signaling information in the service map information is not valid, update the service map information by scanning a frequency band corresponding to the one channel, among the plurality of frequency bands in the broadcast signal.
