Reservation Recording Method of TV by Title Song Comparison

The present invention relates to a reservation recording method of a television, and more particularly, to store a SIF signal representing a title song of a specific broadcast in a memory device and to input a title song of a current broadcast program input at this time when the reserved recording time is reached. The present invention relates to a reservation recording method of a television by title song comparison, which performs reservation recording when it is confirmed by the microcomputer that the scheduled recording is performed by comparing the SIF signal indicated and the SIF signal of the recorded title song with each other.

As the technology of the television develops and the high function and the high quality are advanced, the complex television including the television function and the VCR function is commercialized and sold. Such a composite television has an advantage of easily recording, reserving, and playing back the current broadcast of a television.

In particular, the reservation recording function is frequently used because the viewer can record a specific broadcast without directly watching the broadcast. In general, the reservation recording is performed by inputting a broadcast time. Also, a G-code television is used, in which reservation is easily achieved by inputting a specific code assigned to a broadcast instead of a broadcast time.

However, all of the above-described time reservation or G-code type designates a specific time zone, so when the broadcast time is changed due to the broadcasting station, no broadcast is recorded or a broadcast other than the broadcast designated by the viewer is recorded. Problems arise.

In addition, reservation recording is performed using the VPS and PDC functions that transmit specific information in the teletext, but this has been a problem that cannot be used in a television without the teletext function.

The present invention has been made to solve the above problems, and an object of the present invention is to record a title song of a specific broadcast in advance, and to perform reservation recording only when a title song corresponding thereto is inputted so that a title without malfunction occurs. The present invention provides a method of reservation recording of television by music comparison.

In order to achieve the above object, a reservation recording method of a television set according to the title song comparison of the present invention comprises: a tuner unit 1 for tuning a specific broadcast signal and a modulated and amplified signal output from the tuner unit 1; An IF amplifier 2, a P / S separator 3 for separating the PIF signal and the SIF signal from the signals output from the IF amplifier 2, a memory device 8 for recording data signals, A first step of recording a title song of a specific broadcast to be reserved by a viewer in a memory device (8), comprising: a microcomputer (9) for controlling the whole stroke and a video recording unit for recording a broadcast; A second step of storing, in the microcomputer 9, a reserved recording command of the specific broadcast in which the title song is recorded; A third step of detecting a signal input of the reserved recorded title song and comparing the title song stored in the memory device 8 with the title song of the current broadcast program in the microcomputer 9; And a fourth step of starting a reservation recording operation by outputting a control signal to the video recording unit if the title title song and the title song of the broadcast program are the same as a result of the comparison of the title songs. It features.

Hereinafter, referring to the accompanying drawings, the reservation recording method of the TV by the title song comparison of the present invention will be described in detail.

First, the operating state of the television on which the method of the present invention is performed will be briefly described with reference to FIG. In the television receiver, the weak input current propagated to the air and received by the antenna is received by the tuner section 1, and then output by the IF signal amplification section 2 to amplified CVS up to about 5V. Although not shown in the drawing, the IF signal amplifying unit 2 automatically applies the IF signal according to the magnitude of the input signal voltage so that a predetermined voltage is applied to the image detector 4 even when the input voltage of the television receiver is 0.5 mV or 50 mV. An automatic gain adjustment circuit AGC for controlling the signal amplifier 2 is provided.

The P / S separator 3 is composed of a surface acoustic wave filter and the like, and separates the image intermediate frequency (PIF) and the voice intermediate frequency (SIF) signal from the intermediate frequency signal amplified by the IF signal amplifier 2, respectively. Input to the detector 6 and the image detector 4. The voice detector 6 detects the voice signal from the SIF signal, and then receives the voice signal from the voice processor 7 and outputs the base, treble, and volume according to the control signal from the microcomputer 9. After processing and amplifying a voice such as (volume), it is output through a speaker. On the other hand, the image detector 4 detects the image signal from the PIF signal, and then receives the image signal from the image processor 5, and according to the control signal from the microcomputer 9, the color and tint. By processing signals such as brightness and brightness, a composite signal consisting of R (Red), G (Green) and B (Blue) signals and a synchronization signal corresponding to an image signal is output.

According to the present invention, a memory device 8 for storing a voice intermediate frequency (SIF) signal output from the P / S separator 3 is connected. The memory device 8 stores the SIF signal according to the control signal from the microcomputer 9. The signal stored in the memory device 8 is a signal corresponding to a title song of a specific broadcast and is stored by the viewer designating a recording mode when the title song of a specific broadcast is output through the speaker. The title song thus stored is used as data for judging the input of the reserved recording broadcast. Of course, it will be apparent to those skilled in the art that the recording of the title song can store a signal other than the SIF signal and determine it based on this.

The method of the present invention performed using the television as described above comprises the following steps: a first step of recording, by the viewer, a title song of a specific broadcast to be reserved and recorded in the memory device (8); A second step of storing, in the microcomputer 9, a reservation recording command of a specific broadcast in which a title song is recorded; A third step of detecting a signal input of the reserved recorded title song and comparing the title song stored in the memory device 8 with the title song of the current broadcast program in the microcomputer 9; And a fourth step of starting a reservation recording operation by outputting a control signal to the video recording unit if the recording title song and the title song of the broadcast program are the same as a result of the comparison of the title songs, and maintaining the reservation recording standby state.

The method of the present invention will now be described with reference to the flowchart of FIG. 2.

The method of the present invention begins with the step of storing the title song of a specific broadcast by the viewer in the memory device 8 first. The microcomputer 9 stores the SIF signal output from the P / S separating section 3 in the memory device 8 when the viewer inputs a title song storage command of a specific broadcast from the remote controller 10.

The viewer sends a command to the microcomputer 9 to watch the specific broadcast directly and store it when the title song is output. The title song can store all or the first one or two measures, which can be set by the viewer by pressing the title storage function key.

As described above, while the title song of the specific broadcast is stored, the microcomputer 9 waits for input of a reservation recording command by the viewer. If there is no input of the reservation recording command, the microcomputer 9 does not perform the reservation recording operation.

When a specific broadcast reservation recording command is input by the viewer, the microcomputer 9 detects the SIF signal input from the P / S separation unit 3 and simultaneously inputs the SIF of the reserved recording title song stored in the memory device 8 at the same time. Compare the SIF signal of the broadcast. This comparison process reads and compares a signal input from the P / S separator 3 with a signal from the memory device 8 using a comparator in the microcomputer 9.

As a result of the comparison, if the recorded SIF signal and the currently input broadcast SIF signal are found to be the same, the microcomputer 9 outputs a control signal to the video recording unit to record the current broadcast. Although not shown, the video recording unit may be a video recording unit of a conventional composite television, that is, a television combined with a VCR, or a video recording unit connected to a separate VCR.

After the scheduled recording starts, the video recording unit performs normal recording. End of recording can be set to end automatically after a certain period of time. It is possible to set the time by referring to the expected recording time (this can be easily seen from a newspaper indicating the broadcast time of a broadcast program) when an input key for performing a scheduled recording is pressed.

As described above, according to the present invention, the title song of a specific broadcast is recorded in advance, and reservation recording is performed only when the corresponding title song is input.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
