Description

  The present invention relates to a mobile phone terminal having a function of receiving a television broadcast, and more particularly to a mobile phone terminal with a TV function capable of promptly transmitting information about the frequency of a broadcast station that can be viewed to other terminals.

  In recent years, mobile phone terminals are required to have not only a communication function but also functions as other electronic devices.

  Among them, the spread of mobile phone terminals (hereinafter also referred to as mobile phone terminals with a TV function) having a function of receiving TV broadcasting (in other words, a function as a TV device) is regarded as important. By providing a function of receiving a television broadcast, a user can view the television broadcast in various places.

  TV broadcasts can be viewed when a TV device is located in an area where radio waves from a broadcast station can be received, but the broadcast device from which the radio wave can be received depends on where the TV device is located It depends on the position.

  Conventional television devices are mainly stationary devices that are used fixedly at a predetermined location, so that the reception state of television broadcasts does not change due to changes in the location of the devices. That is, once a device is installed and a receivable broadcast station is set, the television device can always receive radio waves from the set broadcast station unless it is re-installed in another location.

However, in the case of a mobile phone terminal with a TV function, the location of the terminal changes greatly when the user carries the terminal. For this reason, the reception state of the television broadcast wave also changes due to a change in the location of the terminal.
For example, there may be a case where a broadcast wave from a broadcast station that can be viewed at the home of the terminal user cannot be received outside the office, and conversely, a broadcast wave from a broadcast station that cannot be viewed at home can be received outside the office.

For this reason, when a television broadcast is viewed using a mobile phone terminal with a television function, a receivable broadcasting station must be searched every time the television function is activated.
In addition, a user who is watching a television broadcast from a broadcast station searched and detected by a mobile phone terminal with a television function cannot immediately know which broadcast station the user is watching from. Therefore, the user of the mobile phone terminal with a TV function cannot promptly tell the user of the other mobile phone terminal with a TV function which TV station he / she is receiving.

  Prior art relating to a mobile phone terminal with a TV function includes “semiconductor memory device” disclosed in Patent Document 1, “broadcast viewing method, broadcast transmission server, mobile terminal, and multipoint call / broadcast control” disclosed in Patent Document 2. "Viewing device", "Terminal device" disclosed in Patent Document 3, and the like.

  Patent Document 1 discloses a semiconductor memory device that includes tuning means for receiving a radio wave transmitted from the outside and selecting and receiving a radio wave of a required channel, and stores the required radio band information and received radio wave information. Yes.

  Patent Document 2 discloses an invention in which a television broadcast wave from a broadcast station is received by a television broadcast transmission server, and broadcast data is transmitted from the television broadcast transmission server to a mobile terminal via a communication network.

In Patent Document 3, position information to be transmitted from a mobile phone base station is received, information indicating a receivable frequency in a reception area corresponding to the received position information is read from the frequency storage means, and the broadcast frequency is A terminal device that performs reception is disclosed.

To be transmitted to each mobile terminal. This is a broadcasting form completely different from the conventional one, and existing broadcasting equipment cannot be applied. Therefore, it is actually difficult to construct such a broadcasting system.

  Further, the invention disclosed in Patent Document 3 can quickly receive television broadcasts in various reception areas by reading out information stored in the frequency storage means according to the reception areas. However, it is only a terminal device that stores the frequency of the television broadcast in the frequency storage means, and the terminal device that does not store this in the frequency storage means, can receive the desired television broadcast promptly. The search must be performed in the same manner as in the past to find the frequency of the desired broadcasting station.

  As described above, the conventional mobile phone terminal with a TV function cannot transmit information on receivable broadcasting stations to other mobile phone terminals with a TV function.
