  The present invention relates to a television broadcast receiving apparatus and a broadcast channel additional search method, and more specifically, a television that enables comparison between a broadcast channel to be registered and a previous broadcast channel at the end of the additional search of the broadcast channel. The present invention relates to a broadcast receiving apparatus and a broadcast channel addition search method for the apparatus.

  With the spread of digital broadcasting such as BS digital broadcasting, CS digital broadcasting, and terrestrial digital broadcasting, new broadcasting channels tend to increase more and more. In order to register such a new broadcast channel, a television broadcast receiver having a broadcast channel additional search function is known. In a conventional television broadcast receiver, when registration is confirmed after the additional search is completed, a list of channel selection keys (remote control numbers) provided on the remote control and corresponding broadcast channels (channel numbers) is displayed on the screen. Newly found broadcast channels (channel numbers) are sequentially overwritten and registered in the display positions of broadcast channels that could not be received by the search (that is, channel selection keys on the remote controller).

  As described above, in the additional search of the broadcast channel, the channel number that could not be received by the additional search is displayed by being overwritten with the newly found channel number, so the user cannot know the previous registration status. , It is impossible to know which channel number was not received in the additional search. To know this, it is necessary to cancel the additional search process once and return to the previous registration state.

  Regarding conventional additional search processing, for example, in Patent Document 1, the presence / absence of a broadcast signal is determined only for a channel other than a channel registered as having a broadcast signal in a channel map stored at the time of channel initialization performed previously. Thus, there is disclosed a receiving apparatus for additionally registering channel information in which a broadcast signal is newly detected as having a broadcast signal in the channel map.

Further, for example, Patent Document 2 discloses a receiving device that allows a user to add or correct new data. This includes a memory for storing reception frequencies corresponding to a plurality of reception channels, a reception unit for receiving radio waves tuned to the reception frequencies, and a control unit for controlling the memory and the reception unit. In the receiving device that reads the reception frequency of each reception channel according to a predetermined order and operates the reception unit, the memory includes a ROM in which the reception frequency is fixedly written and a RAM in which the reception frequency is rewritably written, The reception frequency data can be additionally registered in the RAM.
