する。[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention provides a method for reserving programs to be viewed on each terminal in a CATV system having multi-channel services such as retransmission and independent broadcasting. The present invention relates to a system that allows users to view and listen to music.
従来、ＶＨＦ 、ＵＨＦＯ内１２〜１６チヤンネル数程
度は、ＶＴＲの選局機能と予約機能によシ、番組予約及
び視聴が可能である。その例を第２図に示す。Conventionally, it has been possible to reserve and view programs on about 12 to 16 channels in VHF and UHFO using the VTR's channel selection and reservation functions. An example is shown in FIG.
ヘッドエンド７から送られるＴＶ倍信号、ＣＡＴＶ伝送
路２を経由してタップオフ３から各端末へ分岐してＶＴ
Ｒ５に入ｆｉ、 ＴＶ受信機４に接続される。The TV double signal sent from the head end 7 is branched from the tap-off 3 to each terminal via the CATV transmission line 2 and sent to the VT.
Enter fi into R5 and connect to TV receiver 4.
ＶＴＲ５の内部に時計を有し、視聴並びに録画する時刻
とチャンネル番号を記憶させておき、該当時刻になると
、自動的に記憶させたチャンネルを視聴並びに録画する
ようになっている。The VTR 5 has a clock inside and stores the viewing and recording times and channel numbers, and when the corresponding times arrive, the stored channels are automatically viewed and recorded.

In the case of a CATV system that is used in
A terminal converter 8 having a multi-channel selection function is used. FIG. 3(b) shows a block diagram of the terminal converter 8.

は録画も視聴も出来ず、選局はひとえに端末コンバータ
８で行なうのみのため、ＶＴＲ５で視聴チャンネル番号
を予約記憶しても意味がなく、予約視聴録画ができない
という欠点があった。When the terminal converter 8 selects the desired channel using the channel selection operation section 13, the channel selection operation section 17 controls the frequency converter 15 to convert the desired channel into one of the two empty channels of the normal TV. By selecting 2 or 1 channel on the VTR 5, viewing and recording becomes possible. Therefore, since the VTR 5 or TV receiver 4 cannot record or view channels other than channel 2 or 1, and channel selection is only performed by the terminal converter 8, there is no point in storing the viewing channel number in advance on the VTR 5. However, there was a drawback that it was not possible to schedule viewing and recording.
本発明のＣＡＴＶにおける番組予約方式は、時刻報知信
号を送出するセンター装置と、時刻とチャンネル番号を
内部に記憶し、前記時刻報知信号が記憶していた時刻と

端末コンバータとを具備することを特徴とする。The program reservation method in CATV of the present invention includes a center device that sends out a time notification signal, a time and a channel number that are stored internally, and when the time notification signal matches the stored time, the stored channel and a terminal converter for setting viewing.

５を経由してＴＶ受信機４へ出力され視聴可能となる。FIG. 1 shows an embodiment of the present invention, tal shows a connection diagram, and FIG. 1(b) shows a configuration diagram of a terminal converter in ial. The time notification signal sent from the center transmitter 1 is received by the terminal converter 6, and if it matches the stored time, it selects the stored channel number, converts it to, for example, VHF 2 channels, and outputs it to the VTR.
5 to the TV receiver 4 for viewing.

へ変換出力するように動作する。By setting the same time stored in the terminal as the timer recording time in advance on the VTR 5 and setting the channel as VHF 2 channel, scheduled recording is also possible. The same figure (b
), 11 is an input terminal, 12 is an output terminal, 13 is a tuning operation section, 14 is a tuning control section, and 15 is a frequency converter. The time notification data signal coming in from the input terminal 11 is separated from the video signal by the filter 16 and sent to the channel selection control section 1.
The time and channel number decoded in step 4 and input in advance from the channel selection operation section 13 are stored in the channel selection control section 14, and if they match, the frequency converter 15 is controlled and the stored channel number is changed. It operates to select, convert and output to VHF 2 channels.
又、視聴停止時刻も同様に記憶させ、時刻が一致すれば
端末コンバータでの視聴を停止するような機能を追加す
ることも可能である。It is also possible to add a function that stores the viewing stop time in the same way and stops viewing on the terminal converter if the times match.
以上説明したように本発明は、センター送信装置から時

画を可能とする効果がある。As explained above, the present invention sends out a time notification data signal from a center transmitting device, stores the viewing start time and channel number in the evening on the terminal computer i (-), and allows viewing if the times match. Channel number VHF 2
Converting and outputting to a channel has the effect of making reservation viewing and recording possible.
