Abstract

PURPOSE: A method for automatically recording urgent news is provided to repeatedly record a same urgent news by judging as to whether a broadcasting is a urgent broadcasting using a broadcasting code and recording an initial urgent broadcasting when the broadcasting is a urgent broadcasting. CONSTITUTION: A method for automatically recording urgent news is identified as to whether a power of a television is turned off(S101). A voluntary channel is tuned and a broadcasting signal is searched when the power of the television is turned off(S102). The method is judged as to whether a urgent broadcasting signal is detected among the searched broadcasting signal(S103). The urgent broadcasting code is stored in a storing means when the urgent broadcasting signal is detected, and a urgent broadcasting is recorded(S104,S105). New broadcasting information is searched through a current tuned channel and it is judged as to whether a urgent broadcasting code is detected among searched broadcasting information(S106,S107). The urgent broadcasting stored in the storing means is compared with the detected broadcasting code when the urgent broadcasting code is detected(S108).

Description

Auto recording method of urgent news

The present invention relates to a recording device (e.g., VCR) capable of recording a television broadcast program. In particular, it is determined whether an emergency broadcast is made through a broadcast code indicating broadcast information. The present invention relates to an automatic emergency news recording method in which the same emergency broadcast detected after the first recording of the broadcast at the first broadcast time is not recorded.

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.

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 microcomputer 600 for controlling overall operation of the VCR by manipulation of the keypad 900C or the remote controller 900B, and the microcomputer 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 The reproduction unit 400 accesses and outputs a signal recorded on a video tape (cassette) through the head H, and receives the character information output from the microcomputer 600 so as to receive and output the image information. OSD processing unit 700 for outputting a character image, and a signal processing unit for processing the signal output from the playback unit 400 and the jitter output from the OSD generation unit 700 to deliver to the TV or CRT side ( 800).

In this case, detailed configurations of the recording unit 300 and the reproducing unit 400 are as shown in FIG. 1, and since the overall operation is a general operation, detailed 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 operation is usually a method in which a user looks at a regular broadcast program and makes a recording reservation. An emergency broadcast includes various kinds of information necessary for life such as an accident news or life information such as danjeon and singular. Irrespective of the urgency, this information is easy to place unless the user is watching television.

An object of the present invention for solving the above problems is to determine whether or not an emergency broadcast through the broadcast code indicating the broadcast information, if it is determined to be an emergency broadcast recording the emergency broadcast that is normally duplicated at the time of the first broadcast The present invention provides a method for automatically recording emergency news such that the same emergency broadcast detected later is not recorded.

Referring to Figure 5 attached to the preferred operation example according to the reservation recording process of the VCR according to the present invention configured as described above are as follows.

In step S101, it is checked whether the power supply of the television is in the "off" state. At this time, the "off" state refers to a standby state. If it is determined in step S101 that the power of the television is off, the flow advances to step S102 to tune to an arbitrary channel to search for a broadcast signal.

At this time, the television broadcasting station encodes various peripheral information other than the television broadcasting program at predetermined time intervals and transmits the radio information together with the television broadcasting program. In step S103, it is determined whether the emergency broadcasting code is detected in the broadcasting information searched in the step S102. do.

If it is determined in step S103 that an emergency broadcast code exists, the process proceeds to step S104. In step S104, the emergency broadcast code detected through the steps S102 and S103 is stored in an arbitrary storage means. The recording unit 300 is driven to record an emergency broadcast.

Subsequently, after recording the broadcast determined to be an emergency broadcast through the process of step S105, the process proceeds to the process of step S106 to prepare for another emergency broadcast that may be later.

In step S106, broadcast information is newly searched through the channel currently tuned in. In step S107, it is determined whether an emergency broadcast code is detected in the broadcast information searched in step S106.

If it is determined in step S107 that an emergency broadcast code exists, the process proceeds to step S108. In step S108, the existing emergency broadcast stored through the process of step S104 is compared with the broadcast code detected through the process of steps S106 and S107. Done.

If it is determined in step S109 that the comparison process in step S108 already has the same information as the currently detected emergency broadcast code, the process proceeds to step S106 to determine whether other emergency broadcast information ends. If it is determined not to exist, the flow proceeds to step S104 to perform the above-described process.

By providing an automatic emergency news recording method according to the present invention operating as described above can record an emergency broadcast generated while not watching a broadcast program through a television receiver, there is an effect that the same emergency broadcast is not stored redundantly. .
