Therefore, it has a number of channels (more than 100 channels are in practical use in the United States). That is,

cA, on TV, the subscription rate is low unless independent programs are produced.
This is one of the factors that hinders the development of CA, T, and V. Conventional CATV mostly involves retransmission of broadcasts, making it difficult to operate outside of areas where viewing is difficult.

画される。[Summary of the Invention] The present invention is directed to a plurality of video cheapres and coders (hereinafter referred to as V
TR is used to record real-time TV broadcasting on the first VTR for a set delay time (time to be delayed from the actual broadcast time), and the recorded tape is recorded a predetermined number of times (delayed broadcast time) for each set time. (equivalent to the number of broadcasting channels) will be recorded again.
最初のテープグ再生状態に成ると同時に2番のテープに
設定時間分の録画が開始され終了と同時に所定回数の再
生が開始される。At the same time as the first tape playback state is entered, recording for a set time is started on the second tape, and at the same time as the recording ends, playback a predetermined number of times is started.
2番再生と同時に3番の録画が開始される。この様に必

ンドレス状態とする。Recording of No. 3 starts simultaneously with No. 2 playback. In this way, the necessary number of devices are connected in succession, and the chain is completed when the predetermined number of devices plus the longest number ends recording and starts playback, and then returns to number 1 and starts recording, resulting in an endless state.

ラインに送出する。Video signals delayed by a set time are obtained from the total number of VTRs (minus one) that are in playback mode, and delay time information is added to these signals and modulated into separate channels for CATV.
Send it to the line.

A tape buffer with the same structure as 4. Intermediate, 3rd exit 5. 6. buffer and 7. Increase the VTR by +1%, 1. The tapes are connected at the entrance to make it endless.・1.3.5.7. Each of the playback VTRs provides a playback output that is delayed in accordance with the buffer capacity time of one hour. □ Now, 1. The reproduction νTR of is delayed by 1 hour, and the V of 3.
2 hours late from TR, 5. There is a delay of 3 hours from the playback VTR, 7. There is a delay of 4 hours from the VTR playing back, and in this way, it is equivalent to the number of playing VTRs multiplied by 6 units of time.

Is there a method that does not include any mechanical parts and programs the recording and playback of VTRs? □Ai' If we use a 4-hour format, we will use 1.5 VT'Rs for each hour plus 1.5 units.
First, record on the first VTR and play it 3' times after the 14th screen.For the second VTR, start recording from 1 hour later, and play it 3 times in the same way as 1 from 1 hour later. In this way, I decided to start recording from the recording barrel, and at the same time as 1-1 entered the door, I started recording the 11th VTG again.
From the ``output'' of TIt', you can smell an output that is delayed by 1 time from the last ``recorded''.

However, it is also possible to use magnetic desks, digital storage devices, etc.' [Effects of the invention] If a device related to unreleased J is installed at a CATV transmitting station,
If we assume a 4-hour delay, a 1-channel, 1-time difference system, and that 6 channels are currently being displayed, we would have 28 channels, 8 channels, 8 systems, and 1. M1

Therefore, compared to ordinary households receiving direct broadcasting, the degree of freedom in channel selection is increased, making it a valuable CATV system. As a result, the number of subscribers will inevitably increase, and sound management can be expected.
