Abstract

PURPOSE:To enable only a program for which its recording is desired to be recorded by transmitting a signal noise with a specified frequency at every start and every end of a CM in a television program or the like and controlling the start and end of the recording in a recorder. CONSTITUTION:A signal noise with a frequency not more than 20Hz that is the minimum for a human's audition is transmitted together with a pictorial image and a topic just before or just after a CM or at every topic in a program from a broadcasting station. On the other hand, using the timetable of a program on a newspaper, weekly musical journal or the like, every program and every topic in the program are numbered and the number is adapted to correspond to the signal noise. When a program with a given number is to be recorded by a video deck, after appointing a date and a channel, the number entered on the side of the timetable is inputted. Thus, only the signal noise corresponding to the number of the appointed program is responded, whereby only the program for which its recording is desired can be recorded.

Description

[Detailed Description of the Invention] This invention provides a newspaper that describes the timetable of two programs.
With the cooperation of broadcasting stations and electrical equipment manufacturers.

The idea is to record only the parts that are of interest.

With conventional recording devices such as video decks, 2. For example, when you want to record a long program such as a movie with commercial cuts, you can operate the video deck one by one using a remote control, etc. by looking at the titles that are displayed on the screen right before and after the commercials. I had to. Naturally, no matter how careful you are, you may forget to operate the device. CM
If you forget to press the stop recording button before entering the
You can rewind during M, but if you forget to press the start recording button when going from a commercial to a program, the whole thing will be over. There is no doubt that a considerable number of video deck users have had this experience: ``The title displayed on the screen alley to introduce a commercial is unavoidable as it is the only signal to notify the commercial. There is no doubt that it is also a burden on those who produce these two programs, which is a burden to those who are trying to record movies in the same complete format as those available on the market.

It's not like the manufacturers were watching it silently; some video deck manufacturers have a mechanism called 0M skip installed, but they can't completely skip commercials, and they also record commercials at the same time as recording. During playback, I had to press the 0M skip button every time there was a commercial. Furthermore, the fact that the 0M skip mechanism was created by the manufacturer shows how many users find commercials to be a nuisance.

Also, if you have scheduled recording of a foreign movie etc. on a video deck, and the time of the program is shifted for some reason 2. For example, if the start time of the foreign movie is shifted due to an extension of a baseball broadcast, it is likely that the final result will not be resolved. The second half of a baseball game that ended without a hit, and a foreign movie that didn't have the last 60 minutes, were recorded.
There are quite a few people who feel like they can't believe themselves when they look at the TV screen.

This situation continues even today, and a huge number of users are struggling with video decks in front of their TVs.

And each manufacturer has worked hard and hard.

I spent a huge amount of money on research and prototyping.

The finished product has not yet been completed.

The present invention was invented to meet such strong demands. I will explain it below.

B. Signal noise (0 , 5 Hz, there is no problem when recording, but the complete numerical value must be determined through consultation between various broadcasting stations and manufacturers of recording equipment such as video decks.) is transmitted along with video and audio.

Mouth Signal noise is classified into four types: control noise, pause noise, record read pause noise, and end noise.

Control noise is transmitted from various broadcasting stations immediately before two programs and their respective topics, and the time for one transmission is 0.8 seconds.

A maximum of 8-degree noise is transmitted every 0.1 seconds, and the first noise among the 8-degree noises to be transmitted is a pasic noise and is absolutely transmitted. The remaining seven signals are set to a control noise pattern by blinking to determine whether to transmit or not.

Since there are seven blinking signals, multiplying by 2 seven times gives a total of 128, but there are 99 patterns used.

Pause noise is a continuous sound of 0.2 seconds, which is mainly transmitted just before the transition from a program to a commercial.

Record read pause noise can be heard on NHK programs and NHK
For programs that do not start on time, the message is sent 8 seconds before the start of a program that starts 100% on time, and at the same time as the commercial of the sponsor of that program starts.

From 1 second 9. The first half is the aforementioned 0.8 seconds of control noise, which is the same as the noise transmitted at the start of the program for 100 berths, and the second half is the signal noise within 0.2 seconds. Send 1 twice.

End noise is related to the program. □It is sent at the end of the program. In NHK programs, at the very end of one program,
Two programs on other stations have finished, and a commercial for the sponsor of that program has finished.
It is a continuous sound of 0.4 seconds.

C. We will discuss the relationship between the circuits of recording equipment such as video decks and signal noise.

First, since signal noise is to be received, a signal noise reception recognition recording interlocking circuit is provided. One program on various broadcasting stations (
When the topic (topic) changes, a signal noise is transmitted, but this circuit can determine whether it is control noise of a reserved program or record read pause noise, and determine whether it is in a recording or pause state or a stop state.
Circuit to stop.

2. Next, regarding the circuit of the recording device regarding signal noise, the recording device is equipped with a safety record circuit that continues recording no matter how many times the control noise is received if it matches the reserved control noise. . Furthermore, a safety pause circuit is provided that does not react to pause noise at all for one second after receiving this control noise.

Regarding pause noise, if the recording device reacts to control noise and record read pause noise and the recording circuit becomes an oven, an all-time pause noise reaction circuit is provided that responds to all pause noises until end noise is received. However, the only exception is while the aforementioned safety pause circuit is operating. Pause noise, as the name suggests, pauses when the recording device receives it and reacts. Also, this circuit allows you to instantly react to the part you want to record, and even if there are two or more topics in one program, you can record without worrying.

Record read pause noise, as the name suggests, is an introductory noise that is used to guide recording.When the recording device sends a signal and responds, it becomes a pause, just like pause noise. A program that doesn't start on .

For example, if a program does not start at the scheduled time from 8 o'clock to 9 o'clock, record read pause noise is transmitted from various broadcasting stations exactly at 8 o'clock.

The recording device receives this signal, puts it into a pause state, and guarantees a complete recording start, so a record read pause noise reaction pause start circuit is provided.

An end noise reaction power off circuit is provided that turns off all circuits when the recording device receives end noise.

This means the end of all reserved recordings.

E. Talking about the circuitry of recording equipment related to program reservations, conventional recording equipment 2 For example, VCRs, the reservation order for VCRs up until now is: First, press the reservation start button.Next, press the date button. The first step is to press the channel button, but the present invention differs from this point in that the user first presses either the normal button or the special button. The recording device is equipped with a circuit that does not respond to pause noise when the normal button is pressed. This allows you to record NHK special programs and programs from other stations with commercials (if you press the normal button, it will not respond to pause noise only, so 0M cut will not be possible automatically). The special button is a button that opens a circuit that responds to all signal noise. This allows all recording controls.

To summarize, the normal button is used to record the entire program including commercials, and the special button is used to record only a portion of the program. In the end, the normal button is the same as the previous recording (recording), but since the signal noise indicating the start of the program is transmitted from various broadcasting stations for each program, 1. For example, even if a baseball broadcast is extended, the signal noise indicating the start of the program will be transmitted after each program. You can perfectly record (record) Western movie theaters etc. that are being aired.

Next, look at the TV (program) timetables in newspapers, weekly music magazines, and weekly TV information magazines. [Program timetables are numbered in order starting from the first program. for example,
The group is Laugh De Iitomo (8) and Mito Komon α→. Each topic in the program is also numbered in order.
<<. For example, if there was a program called The Best Ten, each song would be numbered, and if there was a program called Nice Center 9 o'clock, each song would be numbered. There are 49 numbers for each program and up to 50 numbers for each topic, and all of these 99 numbers are assigned to recording devices.
In the above step, each signal is made to correspond to the control noise in advance. Recorded at the time of reservation
The number written on the timetable of the program (topic).

When you input a number into a recording device, only the corresponding signal noise is recognized, and only the program (topic) you want to record can be recorded. ] Enter the number of the program you want to record.

If you press the normal button to record the entire program, this is the end. If you press the end reservation button to finish, but if you press the special button for partial recording, the next Select either the All button or the Part button. As the name suggests, all the buttons are perfect.

Since the special button is a button that responds to all signal noise, it is essentially a 0M cut button. As the name suggests, the part button is also used for partial recording, but you cannot suddenly press the part button for partial recording; you must press the normal or special button and enter the program number before partial recording can be performed. Can not. And after pressing the part button.

Press the number of the topic you want to record. Also, a next button is provided near the part button. If there are several topics you want to record, press number 2, press the next button, repeat the cycle, press the button for the last topic, that's it, and press the end reservation button. A clear button for programming mistakes and a confirmation button for checking the program are also provided.

Apart from the signal noise reception recognition recording circuit mentioned in section 3.
If the signal noise is not received within 60 minutes after recognizing the reception of end noise after 22:00 and receiving the end noise,
To provide a recording device with a circuit that automatically recognizes that all programs scheduled for that day have ended. This circuit allows complete recording of a program on a single program timetable, even if the program you want to record is after 0 o'clock or if an autochanger is used to record a long program of 24 hours or more.

H. Describe signal noise and program types.

We will explain how to record a TV program using a video deck.

The signal noise arrangement for NHK news programs first transmits record lead noise eight seconds before the program begins. Next, when a program starts, a control noise representing the start of the program is transmitted. For the first news to be broadcast, a pause noise is sent immediately after the control noise, but the control noise, which means the beginning of the second and subsequent topics, is always used at the end of the previous topic. Send immediately before the pause noise that announces the change.

If you send signal noise just before and after the topic, you will naturally send pause noise right after the topic, so every time two topics change, there will be a pause state and the 91st Nice (topic) will also be recorded continuously. In some cases, it is not possible to make it in time.

Therefore, immediately after the control noise immediately before the second and subsequent news (topic), we connect a pause noise that announces the end of the previous news (topic) (control noise 0
．． By connecting 8 seconds plus pause noise 0.2 seconds (total 1 second), two or more continuous recordings are possible using the safety Bose circuit and safety record circuit described in 2.

Then, as soon as the last news ends and the program ends, an end noise is transmitted.

Now, when I try to record the news of the 2nd and 6th Banakasa #≠, it becomes paused due to record read Bose noise, and even if the control noise of the first topic is received, the signal noise reception recognition recording interlock circuit of The recording cannot be started because the signal pattern is recognized by the signal noise reception recognition recording interlocking circuit in the control noise that is sent at the time of the second Nice signal. The second safety pause circuit does not operate on the connected pause noise and continues recording. 3rd When the control noise at the beginning of the news in 3 is applied to the signal noise reception recognition recording interlocking circuit, recording is continued by the safety record circuit in 2, and the connected pause noise is processed by the safety Bose circuit to generate a signal noise. ;Recording continues without entering the state. Even at the time of the fourth 22nd,
At the beginning, control noise is transmitted, but the signal noise reception recognition recording interlock circuit does not react to unreserved control noise, and the second all-time pause noise reaction circuit automatically reacts to the subsequent pause noise. and enters a pause state. This means that since the recording device does not respond to unreserved controller /l// noises, the safety pause circuit does not automatically work and only connected Bose noises are recognized.

Also, for programs (topics) that occur almost every day, a specific number is assigned to the program timetable. For example, suppose NHK has a program called News Center 9 o'clock. If this is a program that occurs almost every day, it will be given a specific number.

Also, if there is an item called the political and economic exchange rate of 1 yen, this is also assigned a specific number. When making a reservation for the recording device, enter the number for Everyday, Channel, News Center 9 o'clock, and the yen exchange number, and leave the videotape in for one year. You can record the market price of the yen, and instantly know the trends over the past year.

Next, 9 topics such as home dramas and baseball commentary remained unchanged 2
To explain the signal noise of programs where partial recording is almost impossible, record read pause noise and control noise, which means the beginning of a program, are the same as the above-mentioned news program guide. This is the most basic system in which the same control noise as the one representing the beginning of a program is also transmitted when transitioning from a commercial to a program. Then, as soon as the program ends, an end noise is transmitted.

I want to record a live baseball game right now, but the weather forecast says there's a 50% chance of rain and I don't know if there will be a game. However, all you have to do is look at the TV schedule and type in the number of the program. This is because if the weather improves and there is a game, the broadcast station will transmit the signal noise of the live baseball game, but if the game is canceled due to rain, the broadcast station will not transmit the signal noise of the program and it will be automatically recorded. will be canceled. In the past, if it rained and the game was canceled, I would record programs I didn't want to watch. Also, the end noise will not be transmitted until the program ends.

Even if the game is extended, you can record it without worrying at all.

If the weather is bad and you want to record a baseball broadcast, but if it's canceled and you want to record a program called We Are the Hyokin Zoku, just enter both numbers. (For programs that may be canceled, such as baseball programs, be sure to write ``When canceled'' on the timetable, and use that.) If there is a game, the broadcast station will send a signal. If the noise is not transmitted, the signal noise of the game will not be transmitted, and the signal noise of the program We Are the Hyokinzoku will be transmitted, and in both cases it can be perfectly recorded.

Next, in the case of foreign movies, there is the issue of signal noise.

The record read pause noise has always been the same, and the control noise at the beginning of the two programs has always been the same, but the commentary before and after the movie and 100% of the movie itself (from the time the commentary ends and the movie starts, to the end of the movie) (up to) change the control noise. (The control noise of the movie from the explanation to the movie itself, and from the commercial to the movie, should be unified.) In the TV timetable, apart from the number of one program,
rCM Ka) 01+02Jr Commercial Video 02".

(01 and 02 are the numbers and letters you press using the heart button.) 01 corresponds to the explanation before and after the movie, and 02 corresponds to the control noise of the movie itself. Now 0M
Even cuts or videos that are exactly the same as commercially available videos can be completely recorded.

Next, let's talk about the relationship between song programs and signal noise.Record read pause noise and control noise that indicates the beginning of a program have always been used, but control noise that indicates the topic (song) of two programs varies from commercial to program. It doesn't just send it when the song moves on, it also sends it every time a song starts, and it sends a pause noise every time a song ends. This allows the video deck user to record only their favorite singers (songs).

Regarding the relationship between various broadcasts and signal noise.

This is exactly the same as when singing TV programs, and control noise is transmitted for each song in opera broadcasts and for each song in singing programs.

Although the time has been set for signal noise such as control noise and pause noise, there is no need to shorten the time, so it is better to shorten it if technically possible.

Out of 99 total control noises, 49 are exclusive to 9 programs.
There are 50 topics dedicated to the two programs.

Record read noise is a signal noise caused by the slow start-up of recording equipment (video decks), but it can be eliminated by developing new equipment.

The present invention is something that a person who has a tinology could not solve as logically impossible.

Discovering unexpected phenomena through a change in thinking and technological improvements,
It is a device of great practical value that has achieved all the long-cherished wishes of the past, such as simplifying reservations, recording reserved programs completely, and cutting 0M.

Claims (1)

[Claims] Signal noise with a frequency of 20 hertz or less, which is the lowest limit of human hearing, can be detected from various broadcasting stations at the start and end of commercials of programs such as TV and FM, or for each topic of the program. The purpose of this system is to control the start and stop of recording in all recording devices and record only interesting topics in movies or programs with commercial cuts. To do this, use program timetables from newspapers, weekly music magazines, etc. A number is assigned to every program and each topic (song) of the program, and the number corresponds to the signal noise. When recording a program on a VCR, you reserve the date and channel, and then type in the number written next to the program on the TV timetable in the newspaper, without reserving the time. Broadcasting stations transmit signal noise for each program and topic of the program, but for example, a video deck will only respond to signal noise that corresponds to the number of the reserved program, and only the program you want to record will be recorded. It means that it can be done. A recording device control system configured as described above.
