Description

  The present invention relates to a channel setting registration system and a television receiver capable of setting a channel of a television receiver that receives a terrestrial television broadcast.

  Conventionally, when starting to use a television receiver for receiving terrestrial television broadcasting, or due to reasons such as moving, the channel of the broadcasting station at the location where it was used and the broadcasting station at the destination In such a case, the user of the television receiver needs to newly set the received channel after the change or change the setting of the already set channel. Arise.

  Furthermore, even when a relay station or the like changes the transmission channel and changes to a broadcast channel that is different from the preset channel, the user of the television receiving apparatus may newly set the new reception channel or change the existing channel. It is necessary to change the setting channel.

  Hereinafter, a conventional channel setting registration method will be described.

  First, the user manually inputs and presets each channel of the broadcasting station based on the television column of the newspaper and the instruction manual. Recently, in order to reduce this effort, it is possible to receive by assigning a region code in advance to each region where the channel of the broadcasting station is different, and selecting and inputting the region code of the installation location. Channels can be set all at once.

  However, there is a limit to the storage capacity of the memory attached to the microcomputer of the television receiver, and it is virtually impossible to cover all the relay stations in each region regarding channel setting registration.

  Hereinafter, a conventional technique for solving the above problems will be described.

  According to the first conventional technique, channel information (CH, frequency, display number, etc.) for each region is registered in a server provided on a general-purpose network by a predetermined method. A television receiver connected to the network via a telephone line or the like accesses the server, downloads data, and displays it on the screen. The user selects the area where he / she lives from the information displayed on the screen. This area selection information is transmitted to the server again. The server selects corresponding predetermined channel information based on the selected information, and transmits the selected channel information to the television receiver. As a result, the television receiver downloads the transmitted channel information and performs channel presetting based on this information (see, for example, Patent Document 1).

  According to the second prior art, the channel preset processing routine and the channel preset table are written in the read-only memory of the television receiver. The channel preset table shows the area code in the telephone number and a list of channels that can be received in the area of each area code. The user operates the operation panel key or the remote control signal generator, inputs his / her telephone number, and registers it in the nonvolatile memory by the microcomputer. Thereby, according to the channel preset processing routine, the microcomputer first extracts the area code of the registered telephone number, and then refers to the channel preset table and receives it in the area specified by the extracted area code. A list of possible channels is selected, and finally, the selected channel list is written into a nonvolatile memory (see, for example, Patent Document 2).

According to the third prior art, the television receiver is provided with a detection unit such as a mobile phone terminal device or a GPS device for detecting the position (location) where the television receiver is present. Based on the set position, channel information corresponding to the service area of the broadcasting station is set (see, for example, Patent Document 3).
