DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control transmitter for pay television by remote control.

[0002]

2. Description of the Related Art In a conventional pay television (hereinafter referred to as "pay television"), a pay television switch is turned on by inserting or inserting a coin or a pay card prepared in advance to replace the coin and a remote control at hand. When a desired channel button of a transmitter (hereinafter, referred to as a “remote control transmitter”) is pressed, a remote control light receiver incorporated in the pay television receives the desired channel and can view an image of the desired channel. Therefore, if you want to watch the video of another channel, you can press the button of the other channel and see the video of the desired channel instead of the video being broadcast. .

SUMMARY OF THE INVENTION In a pay television,
It is in the provision of a TV remote control transmitter and a television that can be watched only on specific channels for free. That is, the pay TV can freely select a desired channel with a remote control transmitter as long as the fee is paid, but for example, a hospital guide is provided by using a specific channel of a pay TV provided in a specific place such as a hospital room. If you do not want to provide it free of charge, specify a specific channel with the remote control transmitter and if a third party points to another channel with the remote control transmitter while the customer is watching it, the image will be put in the later channel Instead, paid videos can be viewed for free. In order to prevent such inconvenience, during transmission of a free specific channel, a remote control transmitter which can transmit only a specific channel without receiving signals of other channels of a normally used remote control transmitter and the remote control transmitter The company will not provide pay TVs equipped with.

SUMMARY OF THE INVENTION The present invention provides an LM that outputs an output signal while outputting a transmission code into a first integrated circuit of a remote control transmitter having only a specific channel.
A P terminal is provided, and an electric signal of remote control transmission completion from the LMP terminal is input to a second integrated circuit provided separately from the first integrated circuit, and the signal transmitted from the LMP terminal is transmitted from the second integrated circuit. Synchronize with a signal or output a remote control transmission signal, transmit it to an electronic switch provided in the first integrated circuit and connected to a specific channel terminal, and operate the electronic switch continuously at regular intervals. Thus, the above-described problem is solved by a configuration in which only a specific channel can be transmitted. In the above, a timer may be used instead of the second integrated circuit in order to synchronize the remote control transmission signal with the transmission signal of the LMP terminal.

[0005]

The conventional remote control transmitter (11) has the configuration shown in FIG.
, A terminal having a plurality of keys NO (K01 to K32) (a transmitting element for transmitting a fundamental frequency = push button),
Light pulse signal using a specific transistor integrated circuit composed of various mechanisms such as light emitting diode (LED) (8), battery (12), capacitor (13), transistor (14), crystal oscillator (15), etc. (11), an LMP terminal (a terminal for outputting an output signal while a transmission code is being output) is set (provided) for displaying a transmission period using a specific one of the transistors in the integrated circuit. ), An optical pulse signal can be transmitted at predetermined intervals to check the transmission state.
As described above, the LMP terminal has a characteristic of outputting an output signal while outputting a transmission code. Next, a pay television (similarly to a normal television) has a built-in light receiver for judging a signal from a remote control transmitter corresponding to each channel and setting a channel.

Accordingly, the present invention provides a remote control transmitter for a television that operates only a specific channel by utilizing the characteristics of the LMP terminal, and a pay television equipped with the remote control transmitter. FIG. 1 is a circuit diagram of a remote control transmitter according to the present invention.
The LMP terminal (1) is provided in the integrated circuit (2) of
Electric signal (3) indicating the end of remote control transmission from P terminal (1)
Is input to a second integrated circuit (4) provided separately from the first integrated circuit (2) and connected to the LMP terminal (1). From the second integrated circuit (4), a remote control transmission signal (5) synchronized with the transmission signal (3) of the LMP terminal (1) is output, and this signal (5) is output from the first integrated circuit. Transmitted to an electronic switch (7) provided in the circuit (2) and connected to the specific channel terminal (6),
The electronic switch (7) is opened and closed, and an electric signal for operating a specific channel from the specific channel terminal (6) is operated as a light emitting signal of a light emitting diode (LED) (8) to a television receiver (9). At the same time, on the other hand, L
From the MP terminal (1), a remote control transmission end signal (3) is sent to the first integrated circuit (4). Thus, the above operation is continuously performed, and the repetitive operation is continuously performed at a constant interval without any interruption, so that the image of only the specific channel is displayed on the television receiver (9). As described above, the signal (3) continuously transmitted from the LMP terminal (1) at a constant interval is continuously transmitted from the first integrated circuit (4) at the same interval, and the electronic signal of the remote control transmitter is transmitted. Since the switch (7) is opened and closed to continuously operate the specific channel (6) at all times, the operation is the same as the operation of pressing and holding the button of the specific channel, and there is no time for receiving a transmission signal from another remote control transmitter. In addition, there is no influence from other remote control transmitters. A remote control transmitter having the above configuration and operation is built in or external to a pay television, and when the power of the television receiver is turned on, the remote control transmitter operates immediately, and only a specific channel image is continuously displayed on the screen. Will be done.

[0007]

As described above, the remote control transmitter according to the present invention is provided with the LMP terminal for outputting the output signal and the terminal of the specific channel while outputting the transmission code to the first integrated circuit. The electric signal at the terminal is input to a second integrated circuit provided separately from the first integrated circuit and connected to the LMP terminal to synchronize the signal, and provided at the first integrated circuit of the remote control transmitter and specified. An electronic switch connected to a channel terminal is continuously opened and closed (ON / OFF operation), and a light-emitting diode (LED) from a specific channel
, A light emission signal is continuously transmitted to the light receiving element of a specific channel of the television receiver at a constant interval, so that there is no room (time) for a transmission signal of another channel from another remote control transmitter to enter. There is an effect that a television receiver having a built-in or exterior remote control transmitter can receive only a specified specific channel.
Especially recently, pay TVs using remote control transmitters have been installed in each room at hospitals, hotels, etc.,
In pay television, the user can watch television by using coins or prepaid cards. However, in the pay-TV system, even if a TV installer tries to provide information such as a business guide and an advertisement for himself / herself or a facility use guide for a hospital or a hotel to a hospitalized patient or a hotel user, it is provided free of charge. There was an inconvenience that it was not possible to pay. In contrast to such a conventional pay television system, according to the present invention, it is possible to immediately provide the above information free of charge without using coins or cards as long as the television is switched on. There is an advantage. Needless to say, there is no need to modify the TV main body, and when pay TV is used, it is convenient to use coins or cards.
