Embodiment Construction

[0036] The current TV has a central processing unit inside, and the professional name is MCU. Its function is to process the operation of the software inside the TV and operate according to the instructions given by the remote control. For example, functions such as channel search and timing are all handled by the MCU. The recall method of the TV channel of the present invention is mainly accomplished by the MCU.

[0037] Referring to the accompanying drawings, the specific implementation method of the present invention is as follows: When the original TV program is interrupted and an advertisement is inserted, the user inputs an instruction to start "TV recall" to the central processing unit in the TV to activate the TV recall function. After the return time is set in the central processing unit, the central processing unit stores the current TV state, such as sound, brightness, color and other relevant data in the memory, and starts timing in the central processing unit. D...

Abstract

This invention relates to a method for recalling TV channels including the following steps: 1)a user inputs an order of starting 'TV recall' to a central processor and sets the return time 2) the central processor stores the present TV state in a memory and begins counting time 3) when the time reaches to the set return time, the central processor pauses operation of other instructions and picks up the data stored in the memory to redesign TV set according to these data and the TV recovers the state before starting the order of recalling TV.

Description

1. Technical field [0001] The invention relates to a TV channel recall method. 2. Background technology [0002] As we all know, there are more and more interstitial advertisements in TV programs now, which makes people tireless. When an advertisement is inserted in the middle of a TV series, most viewers will choose to switch channels to browse other TV programs. Simultaneously, in order not to miss the beginning of the original program, one has to return to the original channel from time to time to see if the advertisement is over and the original program has started. In this way, the audience never tires of it. Simultaneously also often also can miss the connection of original program because changing station is not in time, makes the audience very regrettable. [0003] At present, there are only three methods that can solve the above problems: picture-in-picture, picture-out-picture and manual switching. However, these three methods have their shortcomings, which are...
