And a controller 16 for controlling. Further, this device is provided with an encoder 17 so as to generate a code according to a signal from the controller 16. The encoder 17 also receives a signal representing the title name of the video program from the controller 16 and generates a title code to be inserted into the video program together with a start code and a top code. Further, a mixer 18 is provided on the transmission side, and the code sent from the encoder 17 is inserted into the program sent from the master VTR 15. On the other hand, the receiving device provided in the shop 12 of the station includes a code detecting circuit 20 for detecting the code number included in the video program signal. Also this detection circuit
Reference numeral 20 is connected to the decoder 21 and detects the ID contained in the code signal and decodes the code signal accordingly. The decoder 21 is connected to the controller 22 and switches the mode of the slave VTR 23 according to the signal sent from the decoder 21 to perform the dubbing operation. Further, this apparatus is provided with a printer 24, which prints out information relating to the video program sent from the decoder 21 and leaves the video program recorded in the slave VTR 23 as a reception record. Next, the dubbing operation by such an apparatus will be described. The signal obtained from the encoder 17 is adapted to be inserted over a plurality of horizontal intervals within the vertical blanking interval of the video signal. This will be explained with reference to FIG.
First, when a start signal is generated from the controller 16 by the pulse signal of FIG. 3A, the master VTR 15 is started and the reproduction of the video program of FIG. 3C is started.
The master VTR 15 continues the reproduction of the video program until the controller 16 sends the pulse-shaped stop signal shown in FIG. 3B. From the controller 16, the master VT

The number and other index information (FIG. 3F) are also sent to the encoder. Upon receiving these signals from the controller 16, the encoder 17 encodes the signals to be inserted into the signals of the video program according to a predetermined format. In the example of FIG. 3G, a start code is inserted at the start point of the video program and a stop code is inserted at the end point, each having a length of several tens of frames, and information about the video program is inserted in the period between them. In addition, these codes include the ID required for decoding on the receiving side. The mixer 18 inserts the code signal coded by the encoder 17 into the video program signal.
The code shown in FIG. 3G is inserted into the vertical blanking interval of the signal shown in FIG. 3C several times as shown in FIG. Note that the code signal in FIG. 3G has a bit rate of 100 to several 100 KHz, which is low considering the disturbance in the transmission lines of the transmitting side and the receiving side and the characteristics of the VTR23 on the receiving side. I try to send it over and over again. The output of the video program containing the code signal generated in this way is sent to the print system 13 of the receiving side, that is, the shop 12 of the station by cable or wireless. The video program containing the code signal sent from the transmitting side by cable or wireless enters the code detecting circuit 20 through the input terminal. The code detection circuit 20 detects the code signal included in the video program signal and sends it to the decoder 21. From this signal, the decoder 21 detects the ID contained therein and decodes the code number accordingly. That is, the start signal, stop signal, start signal, and end signal are decoded, and the controller
In addition to sending it to 22, the index information about the video program, that is, the title, time, number and other information is decoded and sent to the printer 24. The controller 22 sends the slave VT by the start signal.

An index signal is generated by the start signal and the end signal of the video program, and is recorded in the slave VTR 23 as an index or cue signal. The slave VTR 23 records the video program, which has passed through the input terminal and the code detection circuit 20, by the controller 22 together with the index signal. Further, the slave VTR 23 will record the title, time, number, and other index information about the corresponding program on the slave tape. The code detection circuit 23 is also capable of extracting the code when the video program recorded in the slave VTR 23 is delivered to the customer as it is. Further, the printer 24 prints out information about the video program sent from the decoder 21 and leaves the video program recorded in the slave VTR 23 as a reception record. The tape cassette recorded by the slave VTR 23 may be a small, eg, 8 mm cassette, and such a cassette may be rented at a store 12 as shown in FIG. A customer who rents the soft tape mounts this cassette in the cassette mounting portion 27 of a small-sized player as shown in FIG. Then, while watching the small television 29, he / she immediately searches for the content he / she wants to watch by using the index operation button 28. A number is determined for each type of index information, and by entering a number according to the type of content such as sports information and fishing information, the information that one wants to know can be viewed quickly. In this way, as shown in FIG. 6, it becomes possible to enjoy the video by playing the rented soft tape using the small-sized player on the train on the way to work.
