Description

  The present invention relates to a television broadcast reception status management system that manages the reception status of each of a plurality of television broadcast receivers.

  2. Description of the Related Art In recent years, with the advancement of network technology, many technologies for connecting a television broadcast receiver to a network and providing various services to the television broadcast receiver via the network have been disclosed.

  As an example, Patent Document 1 discloses that a server transmits channel information corresponding to an area where a television broadcast receiver is installed to the television broadcast receiver via a network. A technique for performing channel preset based on channel information is disclosed.

  According to the technique disclosed in Patent Document 1, since the television broadcast receiver can receive the channel information corresponding to the installation position, the television broadcast of all the channels described in the channel information is originally received. It should be possible.

  However, in reality, in a television broadcast receiver, reception failure may occur due to various factors, and the reception situation may deteriorate. In such a case, the television broadcast of all channels described in the channel information may occur. Can not be received. For example, in a television broadcast receiver, there may be a reception failure such as a ghost failure due to the effects of high-rise buildings and high-voltage lines. Also, depending on the installation location of the broadcast tower, the installation location of the antenna of the television broadcast receiver, and the booster failure Various reception failures may occur.

  Therefore, when trying to improve the reception status at all reception points that receive TV broadcasts, the reception status is grasped for each TV broadcast receiver installed at various reception points, and reception is poor. Some measures need to be taken for the points.

  However, since the technique disclosed in Patent Document 1 does not assume any reception failure in the television broadcast receiver, it is considered difficult to improve the reception status at all reception points.

  In addition, with the widespread use of mobile receivers such as mobile phones that can receive television broadcasts, techniques for providing various services to mobile receivers via a network are also disclosed.

  As an example, Patent Document 2 discloses that in a mobile phone, current location information is transmitted to a broadcast channel information providing device via a network, and the broadcast channel information providing device transmits broadcast channel information corresponding to the location information to the network. A technique for transmitting to a mobile phone via a mobile phone is disclosed.

However, in the technique disclosed in Patent Document 2, although the mobile receiver moves to a reception point that is easily affected by a high-rise building or a high-voltage line, it is likely that a reception failure will occur. Since it is not assumed that a reception failure will occur in the body receiver, it is considered difficult to improve the reception status at all reception points. Furthermore, it is impossible to know where to move to receive broadcast radio waves in areas such as mountainous areas where broadcast radio waves cannot be received.

  As described above, in the prior art, even when a reception failure occurs at any of the reception points, the reception status of the television broadcast receiver or mobile receiver in which the reception failure has occurred is improved. There is a problem that it is difficult to improve the reception situation at all reception points because no measures are taken for this.

  Accordingly, an object of the present invention is to provide a television broadcast reception status management system capable of improving the reception status at all reception points where a television broadcast is received.

  To achieve the above object, the present invention provides a television broadcast reception status management server that receives reception status data indicating a reception status for each channel of a plurality of television broadcast receivers via a network, and receives the received status. A message is transmitted to a television broadcast receiver based on the data.

  For this reason, for example, when there is a television broadcast receiver whose reception condition is supposed to be good but the reception condition is bad, the cause of the bad reception condition of the television broadcast receiver is in the television broadcast receiver itself. Therefore, a message for confirming whether the antenna is correctly installed or whether the booster has failed or not can be transmitted to the television broadcast receiver.

  Thereby, it is possible to improve the reception status by transmitting a message to a television broadcast receiver having a poor reception status due to the factor of the television broadcast receiver itself. In addition, since the TV broadcast receiver itself is a measuring instrument, it is possible to grasp the reception status of each TV broadcast receiver, and since it collects information via the network, it collects the reception status in real time and at a low cost. , Can improve the reception situation quickly.

  In addition, on the TV broadcast reception status management server, for each channel, create a reception status map describing the reception status around the current location of the mobile receiver or the location where the broadcaster terminal is installed on the map. The map is transmitted to a mobile receiver or a broadcaster terminal via a network.

  As a result, it is possible to indicate a reception point with a good reception condition to the mobile receiver, so that a person using the mobile receiver moves to a reception point with a good reception condition and performs a television broadcast of a desired channel. You can expect to receive it. Also, for broadcaster terminals, it is possible to indicate at which reception point the reception failure has occurred, so that the broadcaster can increase the broadcast radio wave to the area where the reception failure has occurred, If the TV broadcast of the channel is a digital broadcast, it can be expected to change the strength of error correction.

  As described above, according to the present invention, the television broadcast reception status management server receives the reception status data indicating the reception status for each channel in each of the plurality of television broadcast receivers via the network, and the received reception status data. Because the message is transmitted to the TV broadcast receiver based on the message, the reception condition can be improved by transmitting the message to the TV broadcast receiver having a bad reception condition. The effect is that the situation can be improved.
