Abstract
A broadcast receiving apparatus includes a determination unit that determines whether an external apparatus is capable of transmitting broadcast program information about a plurality of channels via a communication unit. When the determination unit determines that the external apparatus is capable of transmitting the broadcast program information, an acquisition unit does not acquire the broadcast program information from the digital broadcast signal. The external apparatus is requested to transmit the broadcast program information. The broadcast program information is acquired from the external apparatus.
Claims20
A broadcast receiving apparatus comprising:
- a reception unit configured to receive a digital broadcast signal;
- an acquisition unit configured to allow the reception unit to acquire broadcast program information about a plurality of channels from the digital broadcast signal;
- a communication unit configured to execute bidirectional communication with an external apparatus;
- a determination unit configured to determine whether the external apparatus is capable of transmitting the broadcast program information;
- and
- a control unit configured, when the determination unit determines that the external apparatus is capable of transmitting the broadcast program information, to prohibit the acquisition unit from acquiring the broadcast program information, to request the external apparatus to transmit the broadcast program information, and to acquire the broadcast program information from the external apparatus.
A broadcast receiving apparatus comprising:
- a reception unit configured to receive a digital broadcast signal;
- an acquisition unit configured to allow the reception unit to acquire broadcast program information about a plurality of channels from the digital broadcast signal;
- a storage unit configured to store the acquired broadcast program information;
- a communication unit configured to execute bidirectional communication with an external apparatus;
- a determination unit configured to determine whether the external apparatus is capable of acquiring the broadcast program information from the broadcast receiving apparatus;
- and
- a control unit configured, when the determination unit determines that the external apparatus is capable of acquiring the broadcast program information, to prohibit the external apparatus from acquiring the broadcast program information and to transmit the stored broadcast program information to the external apparatus.
A method for controlling a broadcast receiving apparatus comprising:
- receiving a digital broadcast signal;
- acquiring broadcast program information about a plurality of channels from the received digital broadcast signal;
- executing bidirectional communication with an external apparatus;
- determining whether the connected external apparatus is capable of transmitting the broadcast program information;
- and
- prohibiting, when it is determined that the external apparatus is capable of transmitting the broadcast program information, acquisition of the broadcast program information from the digital broadcast signal, requesting the external apparatus to transmit the broadcast program information, and acquiring the broadcast program information from the external apparatus.
A method for controlling a broadcast receiving apparatus comprising:
- receiving a digital broadcast signal;
- acquiring broadcast program information about a plurality of channels from the received digital broadcast signal;
- storing the acquired broadcast program information;
- executing bidirectional communication with an external apparatus;
- determining whether the external apparatus is capable of acquiring the broadcast program information from the broadcast receiving apparatus;
- and
- when it is determined that the external apparatus is capable of the broadcast program information, prohibiting the external apparatus from acquiring the broadcast program information from the digital broadcast signal, and transmitting the stored broadcast program information to the external apparatus.
A computer readable storage medium storing a computer-executable program of instructions for causing a computer to perform a method comprising:
- receiving a digital broadcast signal;
- acquiring broadcast program information about a plurality of channels from the received digital broadcast signal;
- executing bidirectional communication with an external apparatus;
- determining whether the connected external apparatus is capable of transmitting the broadcast program information;
- and
- prohibiting, when it is determined that the external apparatus is capable of transmitting the broadcast program information, acquisition of the broadcast program information from the digital broadcast signal, requesting the external apparatus to transmit the broadcast program information, and acquiring the broadcast program information from the external apparatus.
