Abstract

PURPOSE:To record plural channels at the same time by continuously switching radio signals which correspond by means of receiving plural channel signals and reproducing the arbitrary channel among the channels recorded with the channel signals. CONSTITUTION:A tuner part 2 which continuously switches the radio signals which correspond by receiving plural channel signals and transmits them with the channel signals, a recording part 3 which records and transmits the radio signal and the channel signals, a reproduction part 4 which can reproduce the arbitrary channel among the recorded channels and an instruction control part 1 which transmits a recording instruction and the channel signals to the recording part 3 and the tuner part 2 at the time of recording and a reproduction instruction and the channel signals to the reproduction part 4 at the time of reproduction are provided. The tuner part which continuously switches the radio signals of plural stations and which transmits them with the channel signals is incorporated and the channel signals are recorded in a tape with the radio signals at the time of recording. Thus, plural channels can be recorded at the same time by one video system.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to video systems.

[Conventional technology]

Traditional video systems can only record one channel at a time.

[Problem to be solved by the invention]

The conventional video system described above has the disadvantage that it can only record one channel at the same time, and therefore requires two or more video systems to record multiple channels at the same time.

[Means to solve the problem]

The video system of the present invention includes a tuner section that receives a plurality of channel signals, continuously switches the corresponding radio wave signals, and sends out the channel signals together with the channel signals; a recording section that sends out recorded recording signals and channel signals; a playback section that can play back arbitrary channels among the recorded channels; and a playback section that sends recording commands and channel signals to the recording section and the tuner section, respectively, at the time of recording; The apparatus is characterized in that it has a command control section that sends a reproduction command and a channel signal to the reproduction section during reproduction.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a system configuration diagram of an embodiment of the present invention.

When a command is sent from the outside to the command control section 1, the command control section 1 sends a channel signal to the tuner section 2 and the playback section 4, and a command to the recording section 3 and the playback section 4.

When channel signals of a plurality of channels are sent from the command control section 1, the tuner section 2 receives the radio wave signals of the specified plurality of channels from the outside, continuously switches all the channels, and sends the channel signals together with the recording section 3. send to

When the recording unit 3 receives a recording command from the command control unit 1,
The radio signal sent from the tuner section 2 is converted into a recording signal and recorded on an internal tape along with the channel signal. Further, when an instruction to output the contents of the tape is sent from the command control section 1, the recording signal and channel signal recorded on the internal tape are sent to the playback section 4.

When the playback unit 4 receives a playback command specifying a channel of a tape recorded on multiple channels from the command control unit 1, it refers to the channel signal sent from the recording unit 3 and generates a recording signal corresponding to the channel signal of the specified channel. Send to outside.

For example, channel A and channel B from the outside.

When a command for simultaneous recording of channel C is sent to the command control section 1, the command control section 1 transmits the channel signals of channels A, B, and C to be switched to the tuner section 2, and also sends the channel signals of channels A, B, and C to the recording section 3.
Sends a recording command to.

The tuner unit 2 selects channels A and B from among external radio signals according to channel signals sent from the command control unit 1.
, C are continuously switched and sent to the recording unit 3 together with the channel signal.

The recording unit 3 receives the channel A that is sent from the tuner unit 2 in response to a recording command from the command control unit 1.

The radio wave signals of B and C are converted into recording signals and recorded on a tape together with the channel signals as shown in FIG.

Next, on the tape recorded from the outside as shown in Figure 2,
When a reproduction command for channel A is sent to the command control unit 1,
The instruction control unit 1 issues an instruction to output the contents of the tape to the recording unit 3.
Furthermore, a reproduction command for channel A is sent to the reproduction section 4.

The recording section 3 sends the recording signal and channel signal of the tape recorded as shown in FIG. 2 to the reproducing section 4 in response to an instruction to output the contents of the tape from the command control section 1.

The playback unit 4 refers to the channel signal sent from the recording unit 3 in response to a playback command for channel A from the command control unit 1, and sends only the recording signal A corresponding to channel A to the outside.

〔Effect of the invention〕

As explained above, the present invention has a built-in tuner section that continuously switches the radio signals of multiple stations and sends them out together with the channel signals, and records the channel signals on tape together with the radio signals during recording, thereby creating a single video system. It is possible to record multiple channels at the same time, and by referring to the channel signals, it is possible to play back any channel recorded on the tape.
