  However, in the inventions and techniques described in Patent Document 1 to Patent Document 6 and Non-Patent Document 1, high-definition and high-quality television broadcasting for a fixed-type television receiver having a large display screen and two channels of channels It has not been realized to enjoy a highly convenient viewing by simultaneously using a television broadcast for a portable terminal device having a selection switch.

  For example, in Patent Document 1, in the section of means for solving problems, if a remote control for a television receiver is incorporated in a mobile phone that receives terrestrial digital broadcasting, only the sound signal output is heard, and the video is transmitted to the television. Although it is described that the image is to be viewed on a large display of the receiver, the configuration is not specifically described in the embodiment, and only a desire is described. In addition, it is not configured to effectively use the two channel selection switches provided in the mobile phone device.

  In addition, Patent Document 2 describes an input button that can be pressed in two steps. For this purpose, it is necessary to change the configuration of the switch, so two channel selection switches that are the current hardware resources. Cannot be used effectively. In addition, since the pressing stroke of the switch becomes large, there arises a new problem that it becomes an obstacle to thinning the apparatus. Furthermore, since a delicate operation of “two-step pressing” is necessary, the user is limited to young people and the like.

  Further, in Patent Document 3, the wireless communication terminal device has a television reception function and a remote control function for operating an external television reception device, and in the remote control mode, only audio can be output from the wireless communication terminal device. Although described, it is not configured to utilize two channel selection switches. Also, without adding a new switch or changing the structure of the switch, the contents of the program of the other channel are checked by the portable terminal device at hand while watching the program of the desired channel by the external television receiver. Thus, every time a predetermined switch is operated, the channel received by the external television receiver and the channel received by the mobile terminal device are not switched.

  In Patent Document 4, in order to easily control the display contents of the screen of the external television and the screen of the remote controller with the remote controller, in addition to the normal direct selection button and the channel up / down switch, Left and right decision sticks must be provided, which will make significant changes to the products currently on the market. It is not configured to utilize two channel selection switches. Further, in Patent Document 4, while a program of a desired channel is being watched by an external television receiver without adding a new switch or changing the structure of the switch, other portable channels can be selected by a portable terminal device at hand. Each time the contents of the program are checked and a predetermined switch is operated, the channel received by the external television receiving device and the channel received by the portable terminal device are not switched.

  In addition, Non-Patent Document 1 describes that a digital TV channel to be received can be selected by operating either a numeric keypad or a forward key, as in the case of a conventional mobile phone device or remote control device. It is not configured to use the channel selection switch. Also, without adding a new switch or changing the structure of the switch, the contents of the program of the other channel are checked by the portable terminal device at hand while watching the program of the desired channel by the external television receiver. Thus, every time a predetermined switch is operated, the channel received by the external television receiver and the channel received by the mobile terminal device are not switched.

In Patent Document 5, a mode changeover switch is required to switch between a remote control mode for transmitting various remote control signals to a large television and a television mode for operating a broadcast reception operation by the remote control side television. In addition, there is a need for a change key that is operated when a television broadcast displayed on the remote control device is viewed on a large television. Therefore, a significant change is made to the product currently on the market, and it is not configured to utilize the two channel selection switches that are the current hardware resources.
Furthermore, in this patent document 5, according to the flowcharts of FIGS. 7, 8, and 9, the channel being received by the remote control device 20 and the channel being received by the large-sized television 10 are operated by operating the change key 22f. Once switched, the channel is not switched even if the change key is operated again. In order to exchange the channels again, the user needs to operate the mode switch 22a and the numeric key switch 22c. This is because the problem of Patent Document 5 is to select and display a desired program scene easily and reliably without incurring wasteful power consumption or reducing the life of the picture tube. While watching the program of the desired channel by the external television receiver, the content of the program of the other channel is checked by the portable terminal device at hand, and the external television receiver receives each time a predetermined switch is operated. It can be said that this is not a replacement of the channel to be received and the channel received by the mobile terminal device.
That is, in Patent Document 5, another program is added by a mobile terminal device at hand while watching a program of a desired channel by an external television receiving device without newly adding a switch or changing the structure of the switch. Each time the content of the program on the channel is checked and a predetermined switch is operated, the channel received by the external television receiver and the channel received by the mobile terminal device are not switched.

  Moreover, in patent document 6, it is not the structure which utilizes two channel selection switches. In addition, after operating the direction selection button (cursor switch) to match the desired channel, by operating the decision button (decision switch), without adding a new switch or changing the structure of the switch, While watching the program of the desired channel with the external television receiver, the content of the program of the other channel is checked with the portable terminal device at hand, and the external television receiver receives each time a predetermined switch is operated. The channel and the channel received by the mobile terminal device are not interchanged.
