JPS59100680A - Converter for wire broadcast receiving - Google Patents

Abstract

PURPOSE:To prevent useless power consumption and unnecessary charging by interlocking a converter for the wire broadcast receiving to a video recording timer of a video tape recorder. CONSTITUTION:A video recording start signal input terminal 1c connected to a video recording timer 3a of a video tape recorder 3 is provided for the converter 1. When an automatic answering video recording is started by the operation of the video recording timer 3a, a video recording start signal is applied to a central processor 8 and a power supply switch 16 is closed. Thus, the converter 5 is not required to be in operating state during the absence.

Description

TECHNICAL FIELD The present invention relates to a converter for receiving cable broadcasting, which is capable of operating a converter in conjunction with the start of recording on a video tape recorder.

BACKGROUND TECHNOLOGY In general cable broadcasting, in order to prevent programs from being eavesdropped on pay program channels, the broadcasting signal is souffled on the transmitting side so that conventional general TV receivers cannot receive the image as it is. /- Performs pull processing and sends out. Therefore, if the receiver wants to receive a pay program channel, a descrambler is required to convert the scrambled video 11 signal into a standard television broadcast signal.

This descrambler is usually built into a multi-channel converter for receiving batting broadcasts so that pay program channels and other retransmission channels can also be received.

On the other hand, paid channel programs transmitted via cable broadcasting include
It includes a variety of programs such as adult programs, feature films, and even plays, and many viewers feel comfortable recording their desired programs on a videotape recorder. In that case, there is no problem if you can operate the video tape recorder according to the broadcast time, but if you happen to be away during the broadcast time and you have to rely on the video tape recorder's built-in recording timer to record while you are away. There is also.

In such a case, it is not possible to turn on the power to the converter for receiving the batting line broadcast at the desired recording time, so conventionally the converter had to be kept in operation during each period when the player was away. However, if the charge system for cable broadcasting is a fixed-rate payment system such as a monthly payment method, electricity consumption will increase while you are away, but it will not affect the payment charge. If the bar view (pa7pθr view) system was used, all broadcasts made during the time the user was away would be charged, which had the disadvantage that it felt like a waste of money.

DISCLOSURE OF THE INVENTION The present invention eliminates the above drawbacks, and by moving the converter for receiving batting line broadcasts to the recording timer of the video tape recorder, the converter for receiving wired broadcasts can be used as a video recorder even when recording while the player is away. It is an object of the present invention to provide a conversion device for receiving wired broadcasting that is activated only when a tape recorder is recording, thereby avoiding wasteful power consumption and unnecessary charges. , a converter that converts the scrambled batting line broadcast television signal into a standard television broadcast signal, and a recording timer of a video tape recorder that records the broadcast signal converted by this converter, and the conversion starts when recording starts while the user is away. The gist of the invention is to provide interlocking means for easy operation.

According to the present invention, the interlocking means connected to the recording timer of the video tape recorder automatically operates the converter when the set time of the recording timer arrives, so that when you want to record cable broadcasting while you are away, This eliminates the need to waste time by leaving the converter in an active state, and it is particularly effective for pay-TV systems in which users pay a fee according to the viewing time.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. The figure is a block system diagram showing an embodiment of the cable broadcast reception conversion device of the present invention.

In the figure, a cable broadcast reception conversion device 1 is connected to a video tape recorder 3 equipped with a recording timer 3a. The signal recorded on the video tape recorder 3 can be played back on the television receiver 2. The cable broadcast television signal from the cable broadcasting station tag is applied to the cable broadcast reception terminal /a of the conversion device l. , are supplied to the converter 3. The converter 5 includes a multi-channel converter 6 and a descrambler 7.
, central processing unit, channel security circuit 9, etc. The cable broadcast television signal is first supplied to a descrambler 7 via a multi-channel converter t. The disk 2 scrambler 7 operates only when the channel security circuit 9 issues a reception permission signal as a result of checking the terminal identification code, and converts the scrambled signal at the time of transmission into a standard television broadcast signal. The standard television broadcast signal obtained by the descrambler 7 is supplied to the video tape recorder 3 from the output terminal /b.

The multi-channel converter t and the descrambler 7 are controlled by the central processing unit and switch the reception mode depending on the type of broadcast, such as whether it is a cable broadcast or not, and whether it is a paid cable broadcast or a free cable broadcast. will be carried out. Note that the central processing unit includes a photodiode 10.
A remote control receiving unit IO to which the remote control signal received by a is supplied, a channel selector //, etc. are connected. The channel number selected by the channel selector l/ is displayed on the channel indicator /l via the central processing unit rty.

/S is a power supply section of converter j, which is connected to a commercial AC power supply via switch /l. This switch /l can of course be switched by manual operation, but can also be switched by a command from the central processing unit r. That is, the conversion device 1 is provided with a recording start signal input terminal /c connected to the recording timer 3a of the video tape recorder 3, and when the recording timer 3a is activated and recording is started while the user is away, the recording start signal is output. The signal is supplied to the central processing unit J', and the central processing unit t closes the switch 16.

Therefore, when the set time of the recording timer 3a of the video tape recorder 3 arrives, it is possible to automatically activate the power supply section IS of the converter 1, thereby changing the operating state of the converter 1 even when the user is away. You can avoid wasting your mental energy and paying extra in a system where you pay based on viewing time.

In addition, in the case of this embodiment, the central processing unit
constitutes the interlocking means.
