A feature of the present invention for achieving the above object is to code a variety of peripheral information (KBPS) other than a television broadcast program at predetermined time intervals and receive a television broadcast program transmitted from a broadcasting station that transmits wirelessly with the television broadcast program to receive a CRT image. In the television broadcast receiver to display on the display, the user first detects the KBPS information corresponding to the specific broadcast program for the reservation operation of the television broadcast receiver, and the KBPS information detected through the first process of the broadcast program A second step of detecting an ID, a third step of detecting a program ID in KBPS information of a broadcast program currently received through a tuning operation of a specific channel in a stopped state of the television broadcast receiver, the second step and the third step A fourth step of comparing the respective program IDs detected in the step, and the image And if it is determined that the program ID detected in the third process is the same as the program ID detected in the second process through the fourth process, operating a television broadcast receiver.

An additional feature of the present invention for achieving the above object is that, if it is determined that the program ID detected in the third process through the fourth process is not the same as the program ID detected in the second process, the third process It further includes a return process to proceed again.

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

First, the Korea Broadcast Program System (KBPS) code will be briefly described. A broadcast code for broadcasting a television broadcast, a program code scheduled to be broadcast, and various kinds of information other than a broadcast program and a predetermined time interval together with a video signal are separated by a predetermined time interval. It will send a different KBPS code that is different from the previous KBPS code for the details changed by the circumstances of the broadcaster.

The television according to the present invention shown in FIG. 2 includes a microcomputer 600 which generally controls the operation of the TV by manipulation of the keypad 900C or the remote controller 900B, and data to be processed by the microcomputer 600. A memory 500 to store, a tuner 100 receiving a broadcast signal of a channel selected by the tuning voltage output from the microcomputer 600 from an antenna ANT, and a broadcast signal received by the tuner 100. IF detector 200 for detecting the intermediate frequency in the operation, and operates according to the operation control signal output from the microcomputer 600 and separates the video signal and the audio signal of the signal output from the IF detector 200 to the video signal An image separator 300 for outputting an image, an OSD generator 700 for outputting a corresponding character image to receive the character information output from the microcomputer 600, and outputting the image information; Signal output from 300) And a signal processor 400 which processes the jitter output from the OSD generator 700 to form a complete image, and operates according to an operation control signal output from the microcomputer 600 and the signal processor 400. CPS driver 800 for receiving the video signal output from the CRT and display the CRT, and the video signal output from the IF detector 200 according to the decoding control signal output from the microcomputer 600 KBPS It is largely composed of the KBPS module 1000 which detects and decodes the code and delivers it to the microcomputer 600.

3 is a flowchart illustrating a method of displaying a selected program in a power saving mode according to the present invention.

In step S101, the microcomputer 600 determines whether the user inputs a request signal for KBPS ID setting using the remote controller 900A or the keypad 900C. If it is determined that there is no input of the request signal, the process proceeds to step S200. It will perform the normal function. On the other hand, if it is determined that the user's request signal is input, the process proceeds to step S102. In step S102, the KBPS module 1000 is controlled to detect the KBPS signal and to display information corresponding to the detected KBPS on the screen of the CRT.

Thereafter, when the user selects a specific program in step S103 while the KBPS information is displayed in step S102, in step S104 an ID corresponding to the program selected by the user in step S103 is stored. Thereafter, in step S105, it is determined whether the power supply is in an off state. When the power supply is not in the off state, a general TV function is performed although not shown.

On the other hand, if it is determined that the power is off, the flow proceeds to step S106 and the microcomputer 600 operates only the functions of the tuner 100 and the IF detector 200 that block the operation of the image separation unit 300 and correspondingly. Tuning operation is performed on the channel.

In the signal input to the KBPS module 1000 due to the tuning operation in step S106, the KBPS module 1000 detects the KBPS signal through the process of step S107, and then detects only the program ID therein. The program ID detected in the process of step S107 is compared with the program ID stored in the step S104 through the process of step S108. If it is determined to be the same, the process proceeds to the stem S109, and if it is different, the process goes to the step S106.

Therefore, in step S109, the power of the TV system is turned on and the program currently tuned is displayed through step S110.

When providing a search method for a playback tape in a VCR according to the present invention operating as described above, a problem that occurs in the search function of the conventional VCR, that is, the user does not recognize the content when performing a fast search function And, when the low speed search function is performed, the problem that the search time takes too long can be solved.
