How to designate preferred channel of television

The present invention relates to a channel setting method of a television. In particular, the present invention relates to a favorite channel specification method for television, which designates, stores, and uses only a channel preferred by a user in a television that automatically sets a channel having a television signal.

Recently, the channel tuning method of television is to automatically set and store only the channel with the broadcast signal, and when the user wants to watch the television, the channel without the broadcast signal is not displayed but only the broadcast channel stored in the channel memory is selected and tuned. It is common.

With reference to the accompanying drawings, a description of the prior art for implementing the channel automatic setting method as described above will be described. 1 is a television block diagram of a related art relating to automatic channel setting using the channel memory. An antenna 1 for receiving broadcast signals transmitted from a plurality of broadcast stations, a tuner unit 2 for tuning a broadcast channel to be watched among the plurality of broadcast signals input from the antenna 1, and the tuner unit 2 above. IF amplification section 3 for amplifying the intermediate frequency of the composite video signal inputted from the channel and P / S separation section for separating the video signal and the audio signal from the composite video signal inputted from the IF amplification section 3 above. (4), a voice processing unit 5 for processing the voice signal input from the P / S separating unit 4 and outputting the voice to the speaker 6, and inputting from the P / S separating unit 4 above. An image processor (7) for demodulating and luminance processing the received image signal, a CRT driver (9) for displaying the image signal of the image processor (7) on the CRT (10), and the image output unit (7). Information of all channels 2 to 69 of the television and the synchronization detecting unit 15 for detecting the synchronization signal from the Stored from the channel memory 14 by the channel memory 14, the external input unit 11 and the receiver 12 providing the channel shut down signal, and the channel shut down signal applied from the receiver 12. It is composed of a microcomputer 13 that receives the channel information is provided to the tuner unit 2 to control the tuning.

The operation of the television configuration related to the automatic channel setting will be explained as follows. The user operates the channel down / down key of the external input unit 11 to apply the channel conversion signal to the receiver 12 of the television. The microcomputer 13 receives the channel change signal and controls the channel memory 14 to apply the channel information stored in the channel memory 14 to the tuner 2 to control the tuning operation. When the television signal exists in the tuned broadcast channel, the synchronization detection unit 15 detects the synchronization in the image processing unit 7 and applies the corresponding signal to the microcomputer 13. The microcomputer 13 stores the channel related to the input synchronization signal in the channel memory 14. Repeating this process, the channel with the broadcasting signal is automatically set and stored among the channels existing in the television. When the user wants to watch television by the key operation of the external input unit 11 in the stored state, only the channel stored and stored above is displayed. On the other hand, the OSD processor 16 displays the channel number to be tuned.

Since the channel is tuned by the channel automatic setting method, the problem of tuning the broadcast channel while seeing all the channels without the broadcast signal in the conventional tuning method is solved. In order to move a channel to a specific channel when the user wants to watch a favorite channel, the user does not prefer the channel. Therefore, it takes a long time to convert the channel, and the channel must be shut down.

The present invention has been made to solve the problems of the conventional TV channel selection method according to the conventional channel automatic tuning method, and an object of the present invention is to select a broadcast channel preferred by a user from a broadcast channel stored in the channel automatic tuning method in a separate memory. It is to provide a preferred channel designation method that can display only the broadcasting channel which the user prefers at all times by storing and manipulating the preferred channel up / down key of the remote controller.
