Abstract

PURPOSE:To receive a satellite broadcast receiving signal received by one set of television receiver incorporated with a tuner (BS tuner) for receiving a satellite broadcast by a television receiver in other place by providing a specific adaptor. CONSTITUTION:When a BS tuner 1 of a television receiver A incorporated with the BS tuner is turned off, when a signal light is emitted from a remote control transmitter to a remote control signal light receiving part 6 of an adaptor B, a control signal received by the light receiving part 6 and decoded is inputted to a switching circuit 4 of the television receiver A and transmitted to the BS tuner 1, and the BS tuner 1 is controlled. Accordingly, even in the case the adaptor B and television receiver C are separated from the television receiver A and installed, the adaptor B is irradiated with the signal light from the remote control transmitter, turn-on of a power source, setting of a channel, etc., of the BS tuner 1 of the television receiver A are executed, and the reproduction can be executed by the television receiver C. In such a way, in a place separated from the television receiver A containing the BS tuner, the contents of a satellite broadcast received by its BS tuner 1 can be reproduced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides satellite broadcasting content received by a television receiver with a built-in satellite broadcasting tuner (hereinafter abbreviated as a BS tuner) to another television receiver. This article relates to a satellite broadcast receiving system that can be played back on a device. [Prior Art] A television receiver with a built-in BS tuner is one in which a BS tuner and a television receiver body are integrated, and the signal system is cruised within the device.

[Problem to be solved by the invention]

Therefore, if it becomes necessary to receive satellite broadcasting at another location, it becomes necessary to move and install the television receiver with a built-in BS tuner or to purchase a new BS tuner.

An object of the present invention is to transmit a satellite broadcast reception signal from one TV receiver with a built-in BS tuner to another TV receiver,
Moreover, it is an object of the present invention to provide a satellite broadcasting receiving system in which the BS tuner of a television receiver with a built-in BS tuner can also be operated. [Means for Solving the Problems] For this purpose, the present invention provides a television receiver with a built-in BS tuner, which is equipped with an external input section for controlling the built-in BS tuner, and a television receiver with a built-in BS tuner.
an adapter that inputs and re-outputs satellite broadcasting video and audio signals output from a television receiver with a built-in S tuner, and includes a light receiving section that receives control light from a remote control transmitter and sends it to the external input section; It consisted of a television receiver that inputs and reproduces the video and audio signals output from the adapter. [Examples] Examples of the present invention will be described below. FIG. 1 is a block diagram of one embodiment. A is a TV receiver with a built-in BS tuner, B is a BS broadcast adapter, and C is a normal TV receiver. First, in the TV receiver A with a built-in BS tuner, l is a BS tuner, and the received signal from the BS antenna. It processes and demodulates the video signal v1 to produce an audio left channel signal, and outputs an audio right channel signal R. 2 is the main body of the television receiver, which inputs, processes, and reproduces signals V, L, and R from the BS tuner and VHF/UHF reception signals from the antenna. Reference numeral 3 denotes a remote control signal receiving section, which sends control signals for turning on/off the power of the BS tuner 1, setting the channel, and turning the power on/off of the television receiver body 2, setting the channel, setting the volume, and the like. Reference numeral 4 denotes a switching circuit which selects either the control signal from the remote control signal receiver 3 or the control signal input manually from the external input section, but priority is given to the control signal from the remote control signal receiver 3. There is.

In the adapter B, this adapter B inputs the video signal V, the audio left channel signal L1, and the audio right channel signal R output from the TV receiver A with built-in BS and outputs them as they are. (for example, a specific channel in the UHF band). This adapter B also includes a remote control signal receiver 6.
will be established. Before use, connect the video signal V, audio left channel signal L, audio right channel signal R lines, switching circuit 4, and remote control signal receiver 6 between the TV receiver A with a built-in BS tuner and the adapter B. Connect each of the lines. For this purpose, use a 4-pair cable, for example. Further, between the adapter B and the television receiver C, the video signal V, the audio left channel signal, the audio right channel signal R, and the lines connecting the RF converter 5 and the antenna terminal ANT are connected. In this case, for example, three pairs of cables are used for the signals V, L, and R, and coaxial cables are used for the rest. When the remote control transmitter emits a signal light toward the remote control signal receiver 3 of the TV receiver A with a built-in BS chainer, the control signal received and decoded by the light receiver 3 is transmitted to the TV receiver 2.
The signal is then sent to the BS tuner 1 via the switching circuit 4.
At this time, VHF or UHF band television broadcasts received by the television receiver 2 or satellite broadcasts received by the BS chainer 1 can be received. At this time, the switching circuit 4 operates upon receiving a signal from the built-in remote control signal receiver 3, so it memorizes it, and as long as the BS tuner I continues to operate based on this operation, the operation from the adapter B No signals are accepted. In other words, after the BS tuner 1 is turned on by the control signal from the built-in light receiving section 3, the switching circuit 4 does not accept the control signal from the adapter B until it receives a control signal from the light receiving section 3 again to turn off the BS tuner. ．． Next, when the BS tuner 1 of the TV receiver 4ilA with a built-in BS tuner is turned off, if a signal light is emitted by the remote control transmitter toward the remote control signal light receiving section 6 of the adapter B, the light receiving section 6 The control signal received and decoded is taken into the switching circuit 4 of the television receiver A with a built-in BS tuner, transmitted to the BS tuner 1, and the BS tuner 1 is controlled.

Therefore, even if this adapter B and TV receiver C are installed separately from TV receiver A with a built-in BS tuner,
By irradiating signal light from a remote control transmitter to adapter B, turning on the power of BS tuner 1 of TV receiver A with a built-in BS tuner, setting the channel, etc., it is possible to playback on TV receiver C. In addition, in this television receiver C, it is up to the side of the television receiver C whether to take in the video signal V, audio left channel signal, and audio right channel signal R, or to take in the RF signal from the RF converter 5. Switch with . In addition, it is possible to use a plurality of adapters B, collect the output signals of their respective remote control signal receivers 6 in a wired-OR style, and connect them to the external power section of the switching circuit 4 of the television receiver A with a built-in BS tuner. You can also. In this case, unless a remote control signal is received by the remote control receiver 3 in the TV receiver A with a built-in BS tuner, the BS tuner of the TV receiver A with a built-in BS tuner is 1 is controlled. [Effects of the Invention] As described above, according to the present invention, it is not only possible to reproduce the content of satellite broadcasting received by a BS chainer at a place far away from a TV receiver with a built-in BS chainer, but also to play back the content of satellite broadcasting received by the BS chainer. The advantage is that you can also operate the BS chainer.
