Abstract

PURPOSE:To automatically make a device cope with a change in an input signal sending schedule by starting a monitor circuit before a magnetic recording circuit is started by a timer circuit. CONSTITUTION:The device is provided with a magnetic recording and reproducing circuit 1 and the timer circuit 2. The reproducing circuit 1 is started at the time set the circuit 2 in advance and also the monitor circuit 3 is started before the set time by the circuit 2. After receiving the input signal, the set time of the circuit 2 is corrected based on the contents of the input signal by the circuit 3. By receiving the input signal by the monitor circuit a little before the time set in the timer circuit in this way, and by checking the contents by various means, the change in an answer schedule can be detected and the set time of the timer circuit is corrected. Then, even in the case that the sending schedule is changed for reasons on a sender's side after a user sets the time in the timer circuit, one part of the contents necessary to be recorded or all the contents do not fail to be recorded since the set time is changed by the action of the monitor circuit.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording and reproducing apparatus such as a video tape recorder (hereinafter referred to as VTR), and particularly to a magnetic recording and reproducing apparatus having a timer recording function. It is related to.

A home VTR is an example of a conventional technology recording and reproducing device.
The timer recording function of conventional home VTRs was as follows. That is, as shown in '131A, the user determines the on/off times of the VTR and sets the times in the advance timer circuit. By doing so, it became possible to turn on and off the recording function at desired times.

Problems to be Solved by the Invention However, in the conventional configuration, after the user sets the time, the signal transmission schedule changes depending on the circumstances of the input signal transmitter (in the case of a home VTR, the broadcasting station is king). If this happens, the user must reset the time, but this is usually not possible. Therefore, there have been problems in that necessary recorded content is cut off, or sometimes unnecessary content is recorded without being recorded at all.

The present invention is intended to solve such conventional problems, and aims to respond dynamically to changes in the input signal transmission schedule.

Means for Solving the Problems In order to solve the above-mentioned problems, the magnetic recording and reproducing apparatus of the present invention includes a magnetic recording and reproducing circuit, a timer circuit, and two monitor circuits, and the timer circuit performs magnetic recording at a preset time. The circuit is started and a monitor circuit is started before a set time, and the monitor circuit receives an input signal and corrects the set time of the timer circuit according to the content of the signal.

The configuration of the monitor circuit includes a natural language processing T1 function that understands sentences contained in audio and video signals given to the monitor circuit as an input signal, or a set time correction function added by the signal sender to the input signal. It also has the ability to detect special signals.

According to the above-mentioned principle, the present invention starts the monitor IoJiS before the timer circuit starts the magnetic recording circuit, so the monitor circuit checks the contents of the input signal and inputs the timer setting time before starting magnetic recording. If it is found that there is a change in the content of the signal, the set time is automatically corrected.

Example An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a functional block diagram of the present invention, mainly consisting of a magnetic recording/reproducing circuit 1, a timer circuit vr2, and a monitor circuit 3.
Consisting of

The magnetic recording and reproducing circuit 1 functions to record input signals and reproduce contents recorded on a magnetic medium, and is controlled to be turned on and off by a signal from a timer circuit 2.

The timer circuit 2 turns on and off the magnetic recording/reproducing circuit at a preset time, and also starts the monitor circuit several minutes (5 minutes to IO minutes) before starting the magnetic recording/reproducing circuit, and outputs the input signal to the monitor circuit. It functions to send to. The monitor circuit receives input signals from the broadcast station and adjusts the set time of the timer circuit depending on the input signal. The gods have a way of determining the content.For example, examples of sentences included in the audio and video signals sent as input signals, 1.This program will be extended by 30 minutes. There is a way to understand it through the multilingual processing function.

Furthermore, if the signal sender inserts a special signal into the audio signal of the broadcasting station, it is possible to change the set time using the signal of the special signal.

Next, the flow of operation of each circuit will be explained using FIG.

First, the user sets the magnetic recording start time in the timer circuit. Then, when the set time approaches, about IO minutes before, the monitor circuit is started by the action of the timer circuit. At this time, the magnetic recording circuit is still stopped.
The monitor circuit receives the input signal, checks its contents, and determines whether to change the set time of the timer circuit. When using self-r8 language processing such as AI for this judgment means 4, it is necessary to understand the sentence included in the audio and video that indicates that the broadcast will be extended, and if there is a change in the transmission schedule of the input signal, it can be adjusted accordingly. Change the set time of the timer circuit. In other words, if the call is delayed by one hour, the set time will also change to become one hour later.

Further, when the contents of the change of history scheduled to be transmitted are added to the input signal as a special signal, the detection system dedicated to the special signal is used as the determination means 4 to judge the contents and change the history of the set time.

In this process, if the set time of the timer circuit is changed, the same determination as described above is repeated at the new set time. If there is no change in history, the timer circuit operates at the set time and starts the magnetic recording circuit.
Start recording.

Therefore, even if the call schedule changes due to the caller's convenience after the time is first set in the timer circuit, the monitor circuit will automatically change the set time and record the necessary information. Recording begins when the content is sent.

Effects of the Invention As described above, in the Otaki recording and reproducing device of the present invention, the input signal is received on the same line as the monitor from a little before the time set in the timer circuit, and the transmission schedule is determined by checking the contents using divine means. Detects changes in history and corrects the set time of the timer circuit. Therefore, even if the calling schedule changes due to the caller's circumstances after the user has set the time on the timer circuit, the monitor circuit will work to change the set time, so the necessary recording content will be updated. This has the advantage of not failing to record part or all of n11.
