Abstract
Description
【発明の詳細な説明】 （産業上の利用分野） 本発明はビデオテープレコーダに関する。[Detailed description of the invention] (Industrial application field) The present invention relates to video tape recorders.
（従来の技術）
従来のビデオテープレコーダの一時停止回路は手動操作
もしくは、テープに記録された制御信号により制御され
るものであった。(Prior Art) The pause circuit of a conventional video tape recorder was controlled manually or by a control signal recorded on the tape.
（発明が解決しようとする課題）
一般にＴＶ放送をビデオテープレコーダで録画する場合
、広告の部分は録画しないことが多い。(Problems to be Solved by the Invention) Generally, when TV broadcasts are recorded using a video tape recorder, advertisement portions are often not recorded.
しかしながら、この種のビデオテープレコーダでＴＶ放
送を録画する場合、広告を録画しないように手動操作で
広告がでるでるたびに一時停止回路を操作しなければな
らず、不便であるばかり−か。However, when recording TV broadcasts with this type of video tape recorder, it is necessary to manually operate a pause circuit every time an advertisement appears, which is not only inconvenient, but also inconvenient.
誤操作により広告を録画したり、録画したいＴＶ放送を
録画しそこなうという問題があった。また、タイマーに
よる自動録画の場合、広告も録画されてしまい、テープ
の録画可能時間が広告の時間分減少するという不都合が
あるものであった。There have been problems in which advertisements may be recorded due to erroneous operations or TV broadcasts to be recorded may fail to be recorded. Furthermore, in the case of automatic recording using a timer, advertisements are also recorded, which is disadvantageous in that the recordable time of the tape is reduced by the advertisement time.
（課題を解決するための手段）
上記問題を解決するために１本発明のビデオテープレコ
ーダは、ＴＶ放送電波中の二音声制御信号、あるいはス
テレオ制御信号、その他の制御信号によって一時停止回
路を制御するように構成したものである。(Means for Solving the Problems) In order to solve the above problems, the video tape recorder of the present invention controls a pause circuit using two audio control signals, stereo control signals, or other control signals in TV broadcast waves. It is configured to do so.
（作 用）

る。同様に、タイマーによる自動録画の場合にも上記作
用は有効である。(Function) With the above configuration, by controlling the pause circuit with the two-audio control signal, stereo control signal, or other control signal in the TV broadcast radio waves, only the TV broadcast that you want to record can be automatically recorded, and the advertisement When this occurs, a pause circuit is automatically activated to prevent the recording of advertisements. Similarly, the above effect is also effective in automatic recording using a timer.

路８は作動せず。(Embodiment) A video tape recorder according to an embodiment of the present invention will be described below with reference to the drawings. When a foreign movie is broadcast on TV, it is almost always broadcast in two audio formats.As shown in Figure 1, the TV broadcast radio waves received by the antenna 1 are sent to the tuner 2 of the video tape recorder body 9 and the audio FM detector. 3, and is detected into an audio signal and a 55.125kHz control channel signal. The control channel signal is passed through a bandpass filter 4, an amplifier 5. The signal passes through the AM detector 6 in order and is detected into two 922.5 Hz audio control signals. The two-voice control signal is detected by the two-voice control signal detection circuit 7. When recording a foreign movie broadcast on TV, if the above two audio control signals are detected, the pause circuit 8 will not operate.
検出されなければ一時停止回路８が作動するように構成

する必要はない。If the pause circuit 8 is configured to operate if it is not detected, it is possible to automatically record only the foreign movies and not to record advertisements at all. Note that the two-audio control signal detection circuit 7 may be a stereo control signal detection circuit or a detection circuit for other control signals, and may be selected depending on the purpose. Furthermore, the components from the tuner 2 to the two-audio control signal detection circuit 7 do not necessarily need to be built into the video tape recorder main body 9.

、実用上きわめて有利なものである。(Effects of the Invention) As described above, the video tape recorder of the present invention
The system is configured so that the pause circuit can be controlled by two-audio control signals, stereo control signals, or other control signals in the broadcast radio waves, so it automatically records only the TV broadcasts that you want to record, and when an advertisement appears. A pause circuit can be activated automatically to prevent advertisements from being recorded. Similarly, the above effects are also effective in automatic recording using a timer, and are extremely advantageous in practice, such as preventing erroneous operations and making effective use of tape.
