The first transmission data is stored in the storage means when it is determined that the first transmission data is normally received, while the second transmission data is determined when it is determined that the second transmission data is normally received. The transmission data is stored in the storage means. As a result, the data reception process can be suitably performed even if the reception state of the transmission data temporarily deteriorates.
JP 2002-369254 A

  However, in the above method, it is necessary to always prepare data having the same content for backup in addition to the original data, and rewrite it according to the reception state, which is not efficient. In addition, there is a problem that it is impossible to cope with the deterioration of the reception state intermittently or for a long time.

  In view of such circumstances, the present invention acquires program identification information of a program whose reception state has deteriorated from the program broadcast schedule information when the reception state has deteriorated to a predetermined level, and includes a broadcast schedule included in the program broadcast schedule information. The present invention proposes a portable terminal with a digital television broadcast reception function that searches for program identification information that corresponds to the deteriorated program identification information. Even if the current state of viewing cannot be viewed due to the deterioration of the reception state, it is possible to assist the user not to miss the program by notifying the user of information related to the broadcast time of the program at the time of rebroadcasting.

  Further, the process of acquiring the program broadcast schedule information from the digital TV broadcast signal of the channel identified by the channel identification information associated with the deteriorated program identification information is intermittent even when the user is not watching the digital TV broadcast. Done. In addition, when there are a plurality of deteriorated program identification information, the portable terminal with a digital TV broadcast receiving function intermittently broadcasts program broadcast schedule information from digital TV broadcast signals of channels identified by a plurality of corresponding channel identification information. Get the. It is also possible to acquire the next program broadcast schedule information after the time after all the programs included in the program broadcast schedule information to be searched are broadcast. Further, when the reception state does not deteriorate to a predetermined level, the good program identification information is acquired from the program broadcast schedule information, and the deterioration that is retained when the deteriorated program identification information corresponds to the good program identification information. The program identification information can also be deleted.

  As described above, according to the portable terminal with a digital television broadcast reception function according to any one or more of the present inventions, even if the current viewing is not possible due to the deterioration of the reception state, By notifying the user or the like, it is possible to assist the user not to miss the program. At this time, when the program name and information regarding the broadcast time are displayed on the display screen of the portable terminal with a digital television broadcast reception function to arouse viewing, it is expected to reduce the risk of missing the program. Further, when information related to a program and a recording request are transmitted to a recording device at a user's house, the program is automatically recorded, which is highly convenient. When viewing digital TV broadcast on a mobile terminal, it is assumed that the reception status of the digital TV broadcast signal deteriorates due to movement or the like, and the program cannot be viewed frequently. Since the program can be viewed and recorded, it is highly convenient.

  In addition, since the user can obtain program broadcast schedule information from the digital TV broadcast signal even when the mobile terminal with the digital TV broadcast reception function is turned off, the current consumption can be minimized. However, it is possible to search for programs that could not be viewed. A portable terminal device that is activated by a rechargeable battery is advantageous because current consumption can be suppressed. Furthermore, if there is program identification information that matches the good program identification information in the deteriorated program identification information, the program has been viewed when the reception state is good or has been partially viewed, It can be considered that it represents a state where there is no need to watch. Therefore, by deleting unnecessary deteriorated program identification information, it is possible to perform a more rapid search process while effectively using a limited storage device.
