Description

How to set the recording section according to the priority in the scheduled recording

The present invention relates to a recording apparatus (e.g., a VCR) capable of recording a television broadcast program. In particular, when a plurality of broadcast programs are recorded on one video tape, the present invention is recorded in a priority order of recordings while sufficiently recording a new broadcast program. Accordingly, the present invention relates to a method of setting the recording section according to the priority in the scheduled recording so as not to damage the previous recordings which are desired to be possessed for a long time.

In general, a VCR is a device for recording a video signal and an audio signal on a magnetizable video tape, and reproducing the video signal and a voice signal if necessary to view the video signal through a display means such as a CRT or a TV. As shown in FIG.

Referring to the configuration shown in FIG. 1, the process of recording / reproducing the received color video signal will be briefly described as follows.

First, in the case of recording, the color image signal input through the low pass filter LPF and the high pass filter HPF is separated into a luminance signal and a carrier color signal, and the separated luminance signal is FM-modulated and amplified. In addition, the separated carrier color signal has a frequency characteristic of 3.58 MHz, which is converted to a low frequency band of 767 kHz (exactly 767.0473 kHz) and amplified to a predetermined size. Thereafter, the luminance signal modulated by the FM in the mixing circuit is superimposed on a low level signal state and recorded on the tape through the video head.

On the other hand, during playback, the information recorded on the tape is accessed through the video head, and the weak signal is amplified to a predetermined size through the amplifier. The amplified signal is separated into an FM modulated luminance signal and a carrier color signal converted into a low frequency band through a low pass filter (LPF) and a high pass filter (HPF). Thereafter, the FM modulated luminance signal is restored to the original luminance signal through the FM demodulation circuit, and the carrier color signal converted to the low frequency band is inversely converted from the low frequency band of 767 kHz to the original frequency band of 3.58 MHz. At the same time, time-base fluctuations (i.e., jitter components) of the signal generated during reproduction are eliminated. Thereafter, the luminance signal and the carrier color signal are mixed through the mixing circuit to be restored to the original video signal.

Since the reproducing process of the above-described process is the reverse process of the recording process, referring to FIG. 2 attached to the conversion process of the signal according to the recording process, as follows.

FIG. 2 illustrates a video signal change process of recording a video signal in the accompanying FIG. 1 in the case of an NTSC video signal.

The overall configuration of the conventional image recording / reproducing apparatus to which the recording / reproducing technique of the video signal is applied is as shown in FIG.

The conventional image recording / reproducing apparatus (hereinafter referred to as VCR) shown in FIG. 3 includes a micom 600 for controlling the overall operation of the VCR by manipulation of the keypad 900C or the remote controller 900B, and the micom 600. Memory 500 for storing data to be processed in the tuner, a tuner 100 for receiving a broadcast signal of a channel selected by the preset voltage output from the microcomputer 600 from the antenna ANT, and the tuner ( The IF detector 200 detects the intermediate frequency from the broadcast signal received at 100, and the video tape (cassette) mounted on the video technology is operated according to the operation control signal output from the microcomputer 600. A recording unit 300 for recording a signal output from the IF detector 200 through H) and an operation according to an operation control signal output from the microcomputer 600 (generally recoil with respect to the recording unit 300). And are seated on the video A playback unit 400 for accessing and outputting a signal recorded on a video tape (cassette) through the head H, and receiving character information output from the microcomputer 600 and outputting the image information. The OSD generator 700 for outputting a text image, the signal output from the playback unit 400, and the signal processor 800 for processing the signal output from the OSD generator 700 and transmitted to the TV or CRT side. It is largely composed of).

At this time, the detailed configuration of the recording unit 300 and the reproduction unit 400 is as shown in the accompanying Figure 1, the overall operation is a general description thereof will be omitted.

Referring to the process of recording a television broadcast in the conventional VCR configured as described above are as follows.

When the user wants to record a specific television broadcast program, the user should be aware of the channel that can receive the broadcast program that he / she wishes to record, and the start time and end time of the program.

Thereafter, the user stores the stored information in the memory 500 through the manipulation of the keypad 900C or the remote controller 900A, and the microcomputer 600 starts the corresponding program based on the information stored in the memory 500. It is determined whether the time has passed through timer counting, and when the start time of the corresponding program is reached, the tuner 100 and the recording unit 300 are operated so that the broadcast received through the antenna is placed on the video tape (cassette). Will be recorded.

In addition, when it is determined that the end time of the program is reached by counting the end time, the microcomputer 600 stops the operation of the tuner 100 and the recording unit 300.

However, the above-described conventional recording method is a method of unconditionally recording the broadcast processed by the recording unit 300 from the current position of the video tape settled in the video technology through the forward driving of the tape, so that if the remaining capacity of the tape is insufficient. There is a problem that can not record all the broadcast.

Furthermore, when a plurality of broadcast programs are recorded and stored on a single tape, when a new broadcast program is to be recorded on a program that is determined to be unnecessary, a new broadcast program is unexpectedly long. There is a case of erasing the recorded broadcast that you want to own for a while.

Therefore, in the conventional method, when storing a plurality of programs on a single video tape, the unexpected phenomenon occurs even though the user does not intend, and the user's careful attention is required to increase the user's inconvenience. .

An object of the present invention for solving the above problems is to record a plurality of broadcast programs on a single video tape, the previous recording that you want to hold for a considerable period of time depending on the priority of the recording while sufficiently recording a new broadcast The purpose of the present invention is to provide a recording section setting method according to priorities in reservation recording so as not to cause damage.

A feature of the present invention for achieving the above object is a first process of setting the importance of the currently recorded program to a specific code when the user records a plurality of programs on one video tape, and the user, The second process of checking the importance of each program set through the first process in the video tape which is settled in the current video technology when recording a new program is requested, and the reverse order of the priority checked in the second process. And a fourth process of recording a new program in a sequence recognized through the third process.

In an additional aspect of the present invention for achieving the above object, the second process includes a first step of rewinding a video tape seated on a video tech and returning it to an initial position; It includes a second step of recognizing the importance of the previously recorded program through the first process.

As an additional feature of the present invention for achieving the above object, the third process includes a first step of re-recognizing the importance recognized through the second process and an order of importance re-recognized through the first step. A second step of detecting the recording time of each program having the lowest priority, the program having the lowest priority, and the recording time point for recording a new program in the first position of the program having the lowest priority in the first step; And a third step of forming a specific recording start position recognition mark.

As an additional feature of the present invention for achieving the above object, the fourth process is sequentially performed in the lowest priority region according to the order of importance re-recognized in the first step of the third process from the point where the recording start position recognition mark is formed. This is for recording while moving to the upper priority area.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a brief description of the technical idea to be applied in the present invention assumes that when a user records a plurality of programs on one video tape, the importance of the currently recorded program is set at each recording time. In this case, in the case of recording any broadcast program, the order according to the importance of the broadcast recording settled on the current video tech is set in the reverse order, and the new program is to be stored based on the order.

Therefore, referring to FIG. 4 attached to an exemplary operation of the present invention according to the technical spirit as described above. However, the hardware configuration is the same as that of FIG.

In step S101, the microcomputer 600 recognizes the broadcast period of the broadcast program that the user wants to record, that is, the recording time, and proceeds to step S102 to rewind the video tape currently seated on the video tech and return to the initial position. .

If the videotape is initialized in step S102, in step S103 the videotape seated on the video tech is forwarded (in this case, the running speed is in the fast forwarding mode) and the importance of the program recorded by the user is increased. Recognize. In this case, when a user records a plurality of programs on one video tape, there is an assumption that the importance level of the currently recorded program is set at each recording point.

The recording process of each program having the highest importance from the program having the lowest importance (including the region without recording) is arranged in reverse in step S104, that is, the priority that was recognized while proceeding to the final position through the process of step S103. Detect.

Therefore, in step S105, a specific recording start position recognition mark is formed so as to recognize the recording time point for recording a new program in the first position of the portion having the lowest importance in step S104.

Thereafter, in the case of recording the broadcast desired by the user in step S101, in step S106, the recording is normally performed from the point where the recording start position recognition mark is formed in step S105. That is, according to the recording area set in step S104, recording is performed while moving from the lower priority area to the upper priority area.

When providing a recording section setting method according to the priority in the reservation recording according to the present invention operating as described above, even if the user does not intend to record a new program when storing a plurality of programs on one video tape Nevertheless, as an unexpected phenomenon occurs, careful attention of the user may be required, thereby increasing the inconvenience of the user.
