Abstract

PURPOSE:To record not only the TV broadcast but other external video or sound signals through the set reservation, by using a selection switch which changes the input sources in response to the reservation set to a timepiece device and providing an input source selection function to a reserved video recording function. CONSTITUTION:In case a TV broadcast is designated as an input signal source, a timepiece device 14 issues a video recording command 5 to a video recording mechanism 1 to start the video recording at a set time point. At the same time, the device 14 also issues an input source selection control signal 8 to an input selection switch 7 almost concurrently with the command 5. A channel selection command 6 is also delivered to a channel selector 3 almost concurrently with the signal 8. When an external signal is reserved, the command 5 is issued to the mechanism 1. At the same time, the switch 7 sends an external input signal 9 to the mechanism 1. Thus a desired external broadcast is recorded in a desired time band.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an improvement in a scheduled recording function in a video tape recorder.

[Prior art]

Conventionally, there has been a device shown in FIG. 1 that performs this type of scheduled recording. In the figure, 1 indicates an image on a magnetic tape;
This is a recording mechanism that records audio signals, and this starts recording in response to a recording command 5, which will be described later.

Termination is commanded. Reference numeral 2 denotes video and audio signals recorded in the recording mechanism 1, in this case, video and audio signals of a television broadcast tuned by the channel selection device 3. Reference numeral 4 denotes a clock device, and if the user sets the desired recording time and television broadcasting channel in advance, the clock device 4 will automatically control the designated channel during the designated time period, that is, between the recording start time and end time. A recording command 5 and a channel selection command 6 are given to the pre-recording and imaging mechanism 1 and the channel selection device 3, respectively, so as to record the signals of the following.

Next, the operation will be explained.

The user sets the desired recording time period and television broadcast channel in the clock device 4 in advance.

Then, when the specified time arrives, the clock device 4 issues a recording command 5 to the recording mechanism 1 to instruct it to start recording, and the clock device 4
issues a channel selection command 6 to the channel selection device 3 almost simultaneously with the recording command 5. The channel selection device 3 receives the channel selection command 6, selects a predetermined television broadcast channel, and supplies the broadcast signal of the selected channel to the recording mechanism 1 as a recorded video/audio signal 2. In this way, recording of the desired channel is started at the desired time, and after waiting for the main operation for the specified time, the recording mechanism 1
ends the recording operation. This termination is carried out by discontinuing the supply of the recording command 5, and the recording of the specified channel for the specified time is completed by all the above operations.

Since the conventional scheduled recording device is configured as described above, it can only record television broadcasts, and externally input video and audio signals other than the above-mentioned television broadcasts can be recorded using a clock device, that is, by setting a reservation. The drawback was that it was not possible. In particular, it has a multi-programmable clock device,
Although there is a demand for video tape recorders capable of recording high-quality audio to record FM stereo radio broadcasts and television broadcasts alternately and without manual touch, the conventional devices described above do not allow for this. In such a case, the input must be manually switched to an external input source and fixed in advance. Therefore, when you want to record TV, you must manually switch the input source. It was impossible to record the bell before the event, and it was very inconvenient.

[Summary of the invention]

The present invention has been made in order to eliminate the drawbacks of the conventional ones as described above, and by providing a recorded video/audio signal selection function to select one of the external input television signals as an input source, It is an object of the present invention to provide a video tape recorder capable of recording external inputs in addition to television broadcast signals.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 shows an embodiment of the present invention, in which the same symbols as in FIG. 1 indicate the same parts, 9 is an external input signal,
This is connected to an external input source, such as FM tune, video disc, etc. 10 is the television signal of the station selected by the channel selection device 3, and 7 is the external input signal 9. Select one of the television signals 10 as an input source, and convert the signal from the input source into the recorded video/audio signal 2.
14 is a clock device,
The device 14 is used to set in advance the recording time desired by the user, whether to use a television signal or an external input signal as a human power source, and if a television signal is to be recorded, which station to record. and the clock device 1
4 is the recording mechanism 1 during the recording time set above.
A recording command 5 is outputted to the selection switch 7, an input source selection control signal 8 is outputted to the selection switch 7, and a tuning command 6 is outputted to the tuning device 3.

Next, the operation will be explained.

The user specifies the desired recording time period and input source in advance on the watch device.
Set it to f14. There are two types of input sources: external broadcasting and television broadcasting. If television broadcasting is selected, the television broadcasting channel is also set in the clock device 14 at the same time.

If television broadcasting is specified as the input signal source, at the specified time, the clock device 14 issues a recording command 5 to the recording mechanism 1 to instruct it to start recording. Further, the clock device 14 issues an input source selection control signal 8 to the input selection switch 7 almost simultaneously with the recording command 5, and also issues a channel selection command 6 to the channel selection device 3 almost simultaneously with the signal 8. As a result, the input selection switch 7 receives the input source selection control signal 8 and selects the designated input signal source, in this case television broadcasting, and the channel selection device 3 receives the command 6 and selects the specified input signal source, and the channel selection device 3 receives the command 6 and selects the specified input signal source, in this case television broadcasting. A channel is selected and the television signal of the selected channel is sent to the input selector switch 7, and as a result, a predetermined television signal 10 is supplied to the recording mechanism 1 as the recorded video/audio signal 2, and in this state. δC! By continuing recording for a predetermined period of time, the television broadcast of the desired station in the desired time slot is recorded.

In addition, when the external signal is reserved, at the specified time, the recording command 5 is output to the recording mechanism 1, and the input selection switch 7 outputs the external input signal 9 to the recording mechanism 1.
As a result, the desired time slot of the desired external broadcast is recorded.

As described above, in this embodiment, since the selection switch 7 is switched by the clock device 14 to switch the input source, -
Once set in the clock device 14, all that is left to do is automatically record the TV without the need for stamps. [Effects of the Invention] As described above, according to the present invention, the input is made according to the reservation setting to the clock device. Since a selection switch for switching the source is provided and the input source selection function is added to the scheduled recording function, there is an effect that not only TV broadcasts but also other external video or audio signals can be recorded by setting the reservation.
