Abstract
A broadcast receiving apparatus and an operating method thereof. The broadcast receiving apparatus includes a receiver for wirelessly receiving a broadcast signal; an external device interface unit for performing short-range communication; and a controller. The controller determines how various frequency bands are to be used.
Claims8
A broadcast receiving apparatus comprising:
- a receiver configured to wirelessly receive a broadcast signal;
- an transmitter configured to perform short-range communication;
- and
- a controller,
- wherein the controller determines whether a frequency band used for reception of the broadcast signal corresponding to one of broadcast channels set as a main channel overlaps with a first frequency band preset for the short-range communication,
- when the frequency band used for reception of the broadcast signal and the first frequency band do not overlap, determines the first frequency band as a frequency band used for the short-range communication,
- when at least a portion of the first frequency band overlaps with the frequency band used for reception of the broadcast signal, determines a second frequency band which is a remaining frequency band, among the first frequency band, excluding a portion overlapping with the frequency band used for reception of the broadcast signal, as the frequency band used for the short-range communication,
- when the main channel is changed in a state of communicatively connected with an external device that is a target of the short-range communication, generates data related to frequency hopping, based on a result of determining whether a frequency band corresponding to the changed main channel and the first frequency band overlap, and
- transmits the generated data related to frequency hopping to the external device, through the transmitter.

A method of operating a broadcast receiving apparatus, the method comprising:
- determining whether a frequency band used for reception of a broadcast signal corresponding to one of broadcast channels set as a main channel and a first frequency band preset for short-range communication overlap;
- determining the first frequency band as a frequency band used for the short-range communication, when the frequency band used for reception of broadcast signal and the first frequency band do not overlap;
- and
- determining a second frequency band, which is a remaining frequency band excluding a portion overlapping the frequency band used for reception of broadcast signal among the first frequency band, as the frequency band used for the short-range communication, when at least a portion of the first frequency band overlaps with the frequency band used for reception of broadcast signal,
- when the main channel is changed in a state of communicatively connected with an external device that is a target of the short-range communication, generating data related to frequency hopping, based on a result of determining whether a frequency band corresponding to the changed main channel and the first frequency band overlap;
- and
- transmitting the generated data related to frequency hopping to the external device.
