Description

  The present invention relates to a television device that receives a television broadcast and an information terminal having a television broadcast viewing function.

  In recent years, a television tuner has been built in a portable information communication terminal, and it has become possible to view a television program regardless of location and time. However, since the monitor provided in the portable information communication terminal is small, it is difficult to see the image on the screen, and the power consumption of the monitor is large. There was an inconvenience that the function was disturbed.

  On the other hand, for such a situation, there has been proposed a device in which an image or both image and sound input / output devices are separated from an information communication terminal and are made stationary as a public communication terminal. According to this, the user can carry only the information communication terminal and take advantage of the freedom to carry around, which is a feature of the wireless videophone, and increase the screen size by using the image input / output device as the public terminal side. There has been proposed a public videophone system that is improved in the ease of viewing, display and usability (see, for example, Patent Document 1).

  There has also been proposed a video terminal device that displays a large screen by causing a video device installed in a public place to receive image information addressed to a user of an information communication terminal that does not have a videophone function or an image display function. (For example, refer to Patent Document 2).

Furthermore, the information distribution server device includes an information distribution server device and a plurality of street television devices. The information distribution device acquires the position of the mobile communication terminal held by the user, selects a street television device close to the position, and selects the selected street television. An information supply system that displays information suitable for a user on a device has been proposed (see, for example, Patent Document 3).
