Description

Search device of index when recording broadcast program operated by G code

The present invention relates to a TVCR that integrates a television receiver (hereinafter referred to as a TV) and a video cassette recorder (hereinafter referred to as a VCR). In particular, a user stores a G code corresponding to a recorded broadcast program as an index in front of the corresponding program. The present invention relates to a broadcast recording content retrieval apparatus using a geocode that can reproduce only a program having a code value corresponding to an input G code.

In general, an image recording / reproducing apparatus (hereinafter referred to as a VCR) is a device for recording a video signal and an audio signal on a magnetizable video tape and reproducing it when necessary to view it through a display means such as a CRT or a TV. The phosphorus configuration is as shown in FIG.

As shown in FIG. 1, the microcomputer 200 is generally connected to the system controller 700 by operating the key input unit 220 to process the overall operation of the TV, and the tuning voltage controlled by the microcomputer 200 is controlled. A tuner 100 for receiving a broadcast signal of a selected channel from an antenna ANT, an image processor 300 for processing an image signal of a broadcast signal received by the tuner 100, and the image processor 300; The vertical synchronizing signal and the horizontal synchronizing signal of the image signal displayed on the screen of the CRT 400 by the image amplifying unit 320 amplifying the output image signal and the vertical / horizontal synchronizing signal processed by the image processor 30. A vertical / horizontal synchronization processor 340 for deflecting, a CRT 400 for receiving an image signal output from the image amplifying unit 320 and displaying it on a screen, and controlling the VCR in general with the microcomputer 200. System controller (500) A deck 600 is connected to the image processor 300 by a control signal of the system controller 500 to record a video / audio signal on a recording medium or to reproduce a video / audio signal from a recording medium. Here, the configuration of the voice processor, the voice amplifier, and the speaker for processing the voice by the control signal of the microcomputer 200 will be omitted.

That is, in the TVCR configured as described above, when a viewer operates the key input unit 220 and selects a broadcasting channel of a TV to be watched in a state where power is applied, the TVCR corresponding to the TVCR recognizes the selected tuning voltage. It generates and applies to the tuner 100. Therefore, the tuner 100 receives the broadcast signal of the broadcast channel selected by the tuner voltage generated by the microcomputer 200 from free space through the antenna ANT and broadcasts it to the image processor 300 and an audio processor (not shown). Input the signal.

Thus, the image processor 300 inputs the processed image signal to the image amplifier 320 by processing only the image signal from the broadcast signal input from the tuner 100 by the control signal of the microcomputer 200. That is, the image amplification unit 320 amplifies the video signal to a level that can be displayed on the screen of the CRT 400 and supplies the image signal to the CRT 400 so that the video signal transmitted from the broadcasting station to the free space is displayed on the screen. Make sure you can watch the signal.

In this case, the vertical / horizontal synchronization processor 340 deflects the image signal displayed on the screen of the CRT 400 in the vertical direction and the horizontal direction based on the vertical synchronization signal and the horizontal synchronization signal processed by the image processor 300. In addition, when the viewer operates the key input unit 220 to select the VCR mode in order to watch the VCR through the TVCR, the recording medium is controlled from the recording medium through the deck 600 by a control signal processed by the system controller 500 associated with the microcomputer 200. The video signal reproduced by reproducing the video / audio signal is processed by the video processor 300.

Accordingly, the image processor 300 processes the image signal reproduced from the deck 600 by the control signal of the microcomputer 200, amplifies the image signal to a predetermined level through the image amplifier 320, and reproduces the image signal on the screen of the CRT 400. Display the displayed video signal.

In the TVCR operating as described above, when recording a plurality of programs on a single video tape, an initial region of a recorded program is indicated by using a VISS signal so that a user can quickly search for each recorded program.

Therefore, when the user selects the program search key, the program proceeds quickly from the initial position or the current position and proceeds normally for a predetermined time from the position at which each VISS signal is detected. Will be judged.

However, in the conventional recording program searching method as described above, the user is inconvenienced because the user has to wind the video tape for a long time and watch an unnecessary program for a predetermined time.

As a prior art to solve the above inconveniences, Korean Patent Application Nos. 96-48887 and 97-21894 can be presented. The technical contents of the Patent Application Nos. 96-48887 refer to the microcomputer in searching for images played on a TVCR deck. Receive the CVBS reproduced from the deck by the signal controlled by the digital signal, store it in the memory as a digital signal, enter the stored date time sequence, etc. to retrieve the video signal, and output the data according to the key input selected by the viewer. A search apparatus including an input image search unit and a search method thereof are provided. Accordingly, the viewer can search the entire video exactly as he or she wants when performing the rewind function by storing the video currently being played on the deck in the memory.

The use of this technique in reverse may solve the above-mentioned problems of the prior art to some extent, but it has a limitation of bringing about a waste of resources due to the addition of additional hardware.

In addition, the technical content proposed in the patent application 97-21894 is a high speed search function to search at a very high speed compared to the speed according to the constant speed driving and a low speed search function to search at a relatively slow speed compared to the high speed search function The present invention relates to a search method of a playback tape that alternately performs a high speed search function and a low speed search function at predetermined time intervals, and expresses audio when performing the low speed search function.

However, since the technique proposed in the above-mentioned patent application 97-21894 is not a VISS method, it has a limitation that a user must manually proceed with the front part of the searched program.

An object of the present invention for solving the above problems is to store only the G code corresponding to the recorded broadcast program as an index in front of the program and play only a program having a code value corresponding to the G code input by the user during playback.
