Television system

By introducing multi-tuners and wireless communication technology into the TV system, signal transmission from the parent TV to the sub-TV is realized, which solves the existing problems of picture damage and inconvenient antenna connection when the sub-TV receives programs, and improves the efficiency of the system. Mobility and aesthetics.

Problems solved by technology

[0006] However, in the method of arranging the antenna cables newly, there is a problem that it takes effort to arrange the antenna cables and also detracts from the appearance
In addition, it is possible to connect indoor antennas to other TVs, or to use other TVs with indoor antennas, although it is possible for terrestrial broadcasting, but for BS / CS broadcasting, the antenna must be placed outside, always facing the direction of the satellite, so unrealistic

Embodiment Construction

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0016] The TV system includes a parent TV (Mother TV) and a child TV (Sub TV).

[0017] figure 1 Indicates the configuration of the parent TV.

[0018] The parent TV, in this example, has the following three tuners: a digital BS / CS tuner 103 , a digital terrestrial tuner 104 , and an analog terrestrial tuner 105 .

[0019] The BS / CS receiving antenna 101 is connected to the digital BS / CS tuner 103 . The terrestrial broadcast receiving antenna 102 is connected to the digital terrestrial broadcast tuner 104 and the analog terrestrial broadcast tuner 105 .

[0020] The digital BS / CS broadcast signal received through the antenna 101 is sent to the digital BS / CS tuner 103 . The TS signal output from the digital BS / CS tuner 103 is input into the matrix switch 110 .

[0021] The digital terrestrial broadcast signal received via the antenna 102 is distributed to the digita...

Abstract

A main television set comprises a plurality of tuners, a selection circuit for selecting, out of receiving signals received by the plurality of tuners, the receiving signal for broadcasting on the main television set as well as selecting the receiving signal for broadcasting on the sub-television set, a first signal processing circuit for processing the receiving signal for broadcasting on the main television set selected by the selection circuit, to generate a video signal and an audio signal for broadcasting on the main television set, a first wireless transmission unit for wireless-transmitting to the sub-television set the receiving signal for broadcasting on the sub-television set selected by the selection circuit, and first control means for controlling the plurality of tuners, the selection circuit, and the first wireless transmission unit.

Description

technical field [0001] The present invention relates to a television system in which programs received by a parent television can be watched and listened to by a child television. Background technique [0002] With the diversification of broadcasting services such as analog terrestrial broadcasting (there will also be digital terrestrial broadcasting in the future), analog BS / CS (Broadcast Sate 1lite / Communication Satellite), and digital BS / CS, televisions (TVs) with multiple tuners built into one increase. [0003] When a user wants to watch multiple programs at the same time with one TV, the multiple programs can be displayed simultaneously on one TV in a picture-in-picture manner. Therefore, when using picture-in-picture to display multiple programs at the same time, usually the image of the sub-picture becomes smaller, and the main picture also becomes missing part of the image due to the sub-picture, so there is a problem that each picture is not good-looking.
