1. A broadcast receiving apparatus having a broadcast receiving unit which selectively receives a broadcast wave specified in accordance with broadcasting network indicating information for indicating one of a plurality of broadcasting networks and channel indicating information for indicating a channel number, comprising:
an instruction receiving unit which receives, from a remote controller, broadcasting network indicating information or channel indicating information; and
a control unit which, when said instruction receiving unit receives broadcasting network indicating information, controls said broadcast receiving unit to
receive a broadcast wave specified in accordance with a combination of a broadcasting network indicated by the received broadcasting network indicating information and a channel number indicated by lastly received channel indicating information if an elapsed time from reception of the lastly received channel indicating information is not more than a predetermined time, and
receive a broadcast wave specified in accordance with a combination of a broadcasting network indicated by the received broadcasting network indicating information and a default channel number associated with said broadcasting network if the elapsed time from the reception of the lastly received channel indicating information is more than the predetermined time.
2. The broadcast receiving apparatus according to claim 1 , further comprising a storage unit which stores, in a memory, a channel number of a finally watched channel in association with each broadcasting network,
wherein the default channel number is the channel number stored in said memory in association with the broadcasting network.
3. The broadcast receiving apparatus according to claim 1 , further comprising an output unit which outputs, to an external device, a video image of the broadcast wave received by said broadcast receiving unit,
wherein said output unit outputs a predetermined image superimposed on the video image until the predetermined time elapses after said instruction receiving unit receives channel indicating information.
4. The broadcast receiving apparatus according to claim 3 , wherein the predetermined image is an image that represents at least one of a broadcasting network and a channel number corresponding to the broadcast wave which is being received by said broadcast receiving unit.
5. A control method of a broadcast receiving apparatus having a broadcast receiving unit which selectively receives a broadcast wave specified in accordance with broadcasting network indicating information for indicating one of a plurality of broadcasting networks and channel indicating information for indicating a channel number, comprising:
an instruction receiving step of receiving, from a remote controller, broadcasting network indicating information or channel indicating information; and
a control step of, when the broadcasting network indicating information instruction is received in the instruction receiving step, controlling said broadcast receiving unit to
receive a broadcast wave specified in accordance with a combination of a broadcasting network indicated by the received broadcasting network indicating information and a channel number indicated by lastly received channel indicating information if an elapsed time from reception of the lastly received channel indicating information is not more than a predetermined time, and
receive a broadcast wave specified in accordance with a combination of a broadcasting network indicated by the received broadcasting network indicating information and a default channel number associated with said broadcasting network if the elapsed time from the reception of the lastly received channel indicating information is more than the predetermined time.
6. The control method according to claim 5 , further comprising a storage step of storing, in a memory, a channel number of a finally watched channel in association with each broadcasting network,
wherein the default channel number is the channel number stored in said memory in association with the broadcasting network.
7. The control method according to claim 5 , further comprising an output step of outputting, to an external device, a video image of the broadcast wave received by said broadcast receiving unit,
wherein said output step outputs a predetermined image superimposed on the video image until the predetermined time elapses after said instruction receiving step receives channel indicating information.
8. The method according to claim 7 , wherein the predetermined image is an image that represents at least one of a broadcasting network and a channel number corresponding to the broadcast wave which is being received by said broadcast receiving unit.
9. A computer-readable storage medium embodying a program for causing a computer to execute respective steps of the control method of claim 5 .
