Embodiment Construction

[0016] Description of drawings: 1 tuner, 2 decoder, 3 picture tube, 4 microcontroller, 5 remote control, 6 control panel, 7 I 2 C bus.

[0017] Such as figure 1 Shown, the present invention is at the remote controller of TV set and control panel, and " add / unlock " key is set, and the channel data item of program channel is provided with flag position, and program channel is realized encryption; The flag bit of the item is reset, the program channel is decrypted, and the "add / unlock" status of the (OSD) program channel is displayed with a lock symbol such as @◎▲■★□◇ in the upper right corner of the display screen.

[0018] The set "add / unlock" key:

[0019] One is to prompt the "add / unlock" status of the program channel;

[0020] The second is to implement the "add / unlock" operation on the program channel;

[0021] The third is to "unlock all" all locked program channels.

[0022] It can be realized respectively by pressing the "add / unlock" key and the length of time:

Abstract

The present invention urilizes TV remote controller and "locking / unlocking" key set on control panel to set and reset flag bit for television channel to be enciphered so as to can implement enciphering and deciphering state prompting, enciphering and deciphering and total deciphering of all the enciphered TV channels. The uipplication of said invention can make user quickly find TV programme channel of inte rest.

Description

technical field [0001] The invention relates to a method for realizing encryption and decryption of television channels, in particular to a method for realizing encryption and decryption of television channels preferred by users. Background technique [0002] With the development of television technology, more and more program channels can be received by TV sets, especially after the national cable TV stations are connected to the Internet, the program channels that TV sets can receive will increase exponentially. On the one hand, it brings more choices to the majority of TV users, and on the other hand, it also brings problems to the convenience of use: to quickly find out the program channels that you need and like from among the many program channels that have been set up, it is currently difficult Time-consuming and troublesome. For example: during the Olympic Games, only want to watch Central Five and Satellite TV Sports Station, if these two program channels, one is p...
