Abstract

PURPOSE:To make an edit easy by broadcasting a tone signal to notice a pro gram, which a viewer does not look forward to, before and after the time zone of it at a broadcasting station side, receiving the tone signal by the auto matic editing function of a VTR device at a viewer side and select-recording. CONSTITUTION:A broadcasting station side broadcasts a tone signal to notice starting at a starting time 15 of a time zone 14 of a program, which a viewer does not look forward to recording, and broadcasts the tone signal to notice an end at ending time 16. The tone signal selects frequency near a voice band upper limit and does not give an unpleasant feeling to the ear of a human. On the other hand, a viewer side sets the automatic editing function selecting switch of a VTR device on, detects the starting tone signal, stops recording temporarily, detects the ending tone signal, cancels a temporary stopping condition and repeats an action to recording ending time 12. Thus, only the program to be recorded can be select-recorded, and editing work is made easy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a TV program automatic editing and recording system for automatically editing recordings of TV broadcast programs.

[Conventional technology]

FIG. 4 shows a front view of the operation panel of a conventional home VTR device. In the figure, (1) is a control panel for setting recording reservation time, etc., (2) is a display panel for displaying time, etc., (
3) is the tape rewind button, (4) is the play button, (5) is the record button, (6) is the stop button, (7) is the fast forward button, (8) is the - hour stop button, and (9) is the - hour button. The stop state indicator lamp 1G is the recording tape insertion/ejection port.

Next, the procedure for recording and reproducing a TV broadcast program using the home VTR device shown in FIG. 4 will be explained. Household V
Regarding the recording operation of the TR, there are usually two operating methods. One is to start recording immediately by pressing the record button (5), and the other is by pressing the control panel (1).
This is a scheduled recording method by setting the recording start time and end time in advance. In either method, the TV program is continuously recorded from the start of recording until it is stopped, or in the case of scheduled recording until the end time is reached, unless another operation button is operated.

[Problem to be solved by the invention]

This conventional VTR device and program broadcasting system have the following problems. That is, all programs from the recording start time to the end time are recorded unless any particular operation is performed during the recording period. Insert programs 1 that are not expected during the program, such as commercials, announcements, etc., are also recorded at the same time. There is a problem in that two VTR devices are required in order to create a new tape by extracting only the desired program from the recording.

Also, during recording, this unexpected program (for example, C
By operating the pause button, it is possible to create a tape in which only the expected programs are recorded from the beginning.

However, it is impossible to operate this pause button on a minute-by-minute basis unless you know the detailed structure of the program in advance.
There was a problem in that a person could not leave the front of the VTR device.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a VTR device and a TV program broadcasting system that make it possible to record only desired programs.

[Means to solve the problem]

The TV program automatic editing and recording system according to the present invention allows broadcasting stations to record programs that viewers are not expected to record, such as commercials.
The automatic editing function 0N10 broadcasts a tone signal to notify you before and after the time period, and the front panel of the VTR device uses this tone signal to pause or cancel recording.
It is equipped with an FF selection switch.

[Effect]

The automatic editing function 0N10FF selection switch of the present invention detects the tone signal emitted by the broadcasting station by operating it and automatically selects and records only the programs desired to be recorded, thereby completely eliminating the need for editing work such as removing commercials, etc.

〔Example〕

In the following - one embodiment of the invention will be described with reference to the figures. 1st
The figure is a diagram showing the temporal flow of TV program broadcasting and the flow of operations on the recording side in the present invention. In the figure, αD is the recording start time specified by a person to the VTR device;
oori is the recording end time, 13+ is the time period of the program that is expected to be recorded, conversely, α is the time period of the program that is not expected to be recorded, α9 is the start time point of the program that is not expected to be recorded, and q61 is the time period of the program that is not expected to be recorded. This is the end time point.

FIG. 2 is a frequency spectrum diagram of an audio channel in TV program broadcasting. In the figure, αη is the audio spectrum of a normal program, (the 1 mark is the upper frequency limit of the transmittable band of the audio channel, fl is the tone signal spectrum that signals the start of an unexpected program, and x is the tone signal spectrum that signals the end of the program. In Fig. 2, the horizontal axis represents the frequency f, and the vertical axis represents the level indicating the strength of the sound.

FIG. 3 is a front view of the operation panel of the VTR device in one embodiment of the present invention, and in the figure, reference numbers (1) to 11 (l) are shown.
is the same as the conventional one, but (2) is an automatic editing function 0N10FF selection switch based on tone signal detection.

Next, the operation and effect of the present invention will be explained.

For programs that are highly likely to be recorded by viewers, such as movie programs and sports programs, the system on the side that produces and broadcasts programs has the ability to The start time of the time slot αΦ of the unexpected program (tone signal α for notifying 19 of the start)
1 is broadcast for about 1 second, for example. Also, the end time αQ
A tone signal will be broadcast for approximately 1 second to notify the end. For each tone signal, as shown in FIG. 2, a frequency close to the upper limit of the audio transmission band is selected so as not to cause discomfort to human ears even if it is broadcast once.

On the other hand, the operations on the side that records the program and the operations of the VTR device are as follows. First, it is necessary to know in advance whether or not the program to be recorded includes a tone signal from a newspaper program table or the like. On top of that, the button to record the program is exactly the same as the conventional VTR device, but the difference is the automatic editing function 0N10FF switch (2) in Figure 3.
If the selection is made in advance, the flow of operation for recording the program in FIG. 1 is as follows. Between the recording start time αD and the recording end time αR, there are program bands that are expected to be recorded (program bands that are not expected such as commercials, etc.
There is a restriction, but this program band (at the start of 141 (19
At the start tone signal (19), the end tone signal (2) is broadcast at the end point f16. In the VTR device shown in Fig. 3, if the automatic editing function selection switch (Co., Ltd.) is ON during recording, recording will be temporarily stopped by detecting the start tone signal, and the - hour stop lamp (9) will be lit. do. Next, when the program band (14) ends, an end tone signal (2) is broadcast, and when the VTR detects this, the paused state is canceled, the lamp (9) is turned off, and recording is performed again. In this way, the recording and pause state are repeated until the recording end time α2 is automatically performed by detecting the tone signal of the VTR device.

Furthermore, if recording is performed with the automatic editing function switch (Inc.) turned OFF, it is also possible to record in the same manner as with a conventional VTR device, and the recording side can freely change the operating mode at its own discretion. You can choose.

〔Effect of the invention〕

As described above, according to the present invention, by broadcasting a tone signal between an expected program and an unexpected program and detecting this on the VTR device side, it is possible to prevent the unexpected program from being recorded and to record it. It is no longer necessary to edit the tape using two VTR devices after recording, resulting in economical and time saving effects.
