[0056] figure 1 are exemplary views for explaining the structure of the broadcast receiver according to the first embodiment of the present invention.

[0057] The broadcast receiver is a small receiver such as a user can carry. The broadcast receiver is capable of receiving broadcast signals such as television broadcasts as broadcast signals. Such as figure 1 As shown, the broadcast receiver includes: an antenna 101, which is used to receive broadcast signals; an analog front-end unit (hereinafter referred to as the front-end unit) 102, which is used to extract and demodulate the broadcast of the set channel in the broadcast signal received by the antenna 101 signal in order to output its digital signal; the decoder unit 103 is used to decode the digital signal and output the video signal and the audio signal; the display unit 104 is used to display the video signal; the audio output unit 105 is used to use the audio signal as Sound output; storage unit 106, such as non-vo...

[0094] The broadcast receiver sometimes changes its installation location while maintaining a state capable of receiving broadcast signals. In this case, for example, the user watches the program while riding in transportation such as a vehicle and a train.

[0095] In this case, it can be considered that two situations are the main reasons why the broadcast receiver has moved to an area where the broadcast signal cannot be received, such as tunnels, underground, and mountainous areas, such as a tunnel, underground, and mountainous areas, and Move from the area where the broadcast receiver is located to any adjacent area. In the former case, the broadcast receiver cannot reallocate channel numbers (update channel settings). By considering this situation, update of channel setting should not be performed. Therefore, the second embodiment quickly updates the channel setting in response to the latter case, that is, in response to the movement of the installation location from t...

Abstract

A CPU confirms a receivable channel while sequentially changing channel numbers set to an analog front-end unit and specifies an area in which the receivable channel can be received and an area adjacent thereto by referring a receiving channel table by area and an adjacent area table after confirming the receivable channel. After this, the CPU confirms the receivable channel while sequentially setting the channel numbers receivable in the adjacent areas to the front-end unit to specify areas matching with the confirmation result. When the number of specified areas becomes one, the CPU assigns channel numbers to each switch formed of a channel switch group of a user interface unit.

Description

technical field [0001] The present invention relates to a broadcast receiver configured to receive a broadcast signal transmitted for each channel, and extract a broadcast signal of a channel desired by a user from the received broadcast signal. Background technique [0002] Currently, broadcast receivers for television broadcasting are commercially produced in large quantities, such as a type premised on moving its installation location and an installation type. The latter type includes broadcast receivers such as portable small-sized broadcast receivers, cellular phones on which a broadcast receiving function is mounted, and vehicle-mounted broadcast receivers. Recently, a large number of personal computers equipped with a broadcast receiving function have been commercialized. [0003] Most broadcast receivers are configured to assign channel numbers to operating parts for channel designation (tuning) so as to view channels assigned to the channel numbers of the operating...
