Description

[Detailed description of the invention] The present invention relates to a video charging system.

2. Description of the Related Art Conventionally, inns, hotels, etc. have broadcast videos using empty television channels. In that case, the TV is equipped with a coin timer so that the video image can only be viewed when the correct coin is inserted. Most of the operation of video cameras (hereinafter referred to as VTRs) is automated, and the VTR control circuit has a built-in timer for controlling the time between two lines and is controlled according to a preset program.

This method had the following drawbacks. 1) Since the VTR is broadcast at a set time, it is not always the case that the VTR is on when the customer wants to watch it.

(2) Even if there is no one to watch it, the VTR will continue to broadcast the program according to the program, so there is no point in watching it.

An object of the present invention is to provide a video charging system that eliminates the above-mentioned drawbacks.

The present invention will be described below based on illustrated embodiments.

The antenna 1, mixer 2, duplexer 3, and main distributor 4 are connected in series by a transmission cable 5.

The transmission cable 5 branched into each line from the main distributor is connected to a guest room distributor 6, 6, 6, etc. provided in each guest room.
... are connected in series. Further, a transmission cable 5 branched from the distributor 6 is connected to a television 8 via a mixer 7 and a channel gate 9. The wiring from the mixer 7 is the channel gate 9 and the oscillator 10.
The line goes through Channel Gate 9 to TV 8.
The other line is connected to the oscillator 10.

Note that power for the channel gate 9 and the oscillator 10 is supplied from a coin timer 11. Further, the power plug 12 of the coin timer 11 is inserted into an indoor commercial power outlet, and the power plug 13 of the television 8 is inserted into an outlet provided on the coin timer 11. The distribution terminal of the duplexer 3 and the receiver 14,
The output circuit 15, the VTR control circuit 16, the VTR 17, the modulator 18, and the input terminal of the mixer 2 are connected in series.

Since the circuit according to the system of the present invention is configured as described above, when a guest wants to watch TV in a guest room of an inn or a hotel, all they have to do is turn on the TV, and the TV radio waves enter from antenna 1 and mixer 2. , the duplexer 3, the main distributor 4, the guest room distributor 6, and the channel gate 9 of the mixer 7 to enter the television 8, where the television can be viewed.

In this case, there is no direct relation to the coin timer 11, and even if the swimming game has already been broadcast, the channel gate 9 blocks the Vm signal and the VTR
cannot be viewed. The channel gate 9 does not block signals of frequencies other than a specific frequency (VTR signal).

When a customer wants to watch a VTR, by inserting a proper coin into the coin timer 11, the oscillator 10 oscillates and the channel gate 9 is opened. The oscillated signal flows through the transmission cable 5 as shown by the arrow, passes through the passenger compartment distributors 6, 6, 6, the main distributor and the main distributor 3, and then reaches the receiver 14.
The received signal is received by the receiver, and the VTR control circuit 16 is operated via the reception output circuit 15 to automatically broadcast the video on the VTR17.

■The video signal of TRl7 is sent to the mixer 2 via the modulator 18.
The signal is transmitted to the television 8 via the duplexer 3, the main distributor, the main distributor, the main distributor, the mixer 7, and the mixer 7. In this case, since the channel gate 9 has already been opened by inserting a coin, the user can view the VTR. When the set time of the coin timer 11 ends, the channel gate 9 is returned to its original state, even if the VTR
Even if it is being broadcast to another room, it cannot be viewed on the TV 8. The part surrounded by the broken line in the figure is the main part of the present invention.

The frequency of VHF radio waves currently used for television broadcasting is 91.25 MHz for the first channel, and the other channels increase in frequency at 6 MHz intervals. The oscillation frequency used for the oscillator 10 of this system is, for example, 30~
If a 50 MHz one is used, there is no risk that the above oscillation will interfere with the images of the television radio waves.

Furthermore, if VHF or the like is used as the signal frequency of the oscillator 10 that operates the VTR control circuit 16, the TV and VTR transmission cable 5 can be used as is, so the existing
When installing the VTR control circuit of the present invention in TR equipment, wiring work for the signal transmission circuit is not required. In addition, ■■ will be shown only when the customer inserts a coin into the coin timer 11, so the VTR will be displayed at any time during the period of 2@ at the customer's preferred time.
This is convenient because you can see it. For example, if you want to manage the movement status of ■■ for each room, you can change the frequency of the oscillator 10 slightly for each room, and
This is made possible by matching the tuning circuit of the receiver 14 that receives this to the above frequency. By applying this system, it is possible to create various rationalization systems other than those mentioned above.

Claims (1)

[Claims] 1. A channel gate that disables viewing of the VTR when proper coins are not inserted, and enables viewing of the VTR only when proper coins are inserted, and operates the VTR control circuit to start the VTR only when coins are inserted. The circuit is composed of a coin timer integrated with an oscillator that oscillates a signal for the purpose of transmission, and a receiver that receives the signal and operates the VTR control circuit, and transmits the signal to the existing TV and VTR. A video pay system characterized by transmission using cables.
