Description

Technical field:

[0001] The invention relates to a method for realizing a TV real-time clock. Background technique:

[0002] At present, when the known TV sets are powered off and shut down, the central processing unit (CPU) of the TV set stops working, the TV software stops running, and the timer or counter in the central processing unit (CPU) of the TV set does not work. work again. Thus, the clock implemented by software stops counting. In this way, the user has to reset the clock every time the TV is turned on, so as to correctly realize the timing function of the TV, which is very inconvenient for the user. Especially functions such as timing shutdown, timing turntable, timing reminder are difficult to realize. Invention content:

[0003] The object of the present invention is to provide a method for realizing a TV real-time clock in order to solve the above problems.

[0004] In order to achieve the above object, the present invention proposes a method for realiz...

Examples

Embodiment Construction

[0009] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0010] The present invention is based on the TV hardware and software system, through the improved infrared remote controller of the TV, when the TV is powered on and there is no button, the real-time clock signal is sent to the TV at regular intervals, and the TV receives and decodes to provide Used as a timing function for the central processing unit (CPU). And it can be displayed on the TV screen through an on-screen display (OSD) module.

[0011] The technical solution of the present invention's function realization is: on the basis of television software, hardware and system, at first the infrared remote controller of the television is improved. figure 1). The second, minute, hour, week, day, month, and year of the real-time clock are respectively coded as command code words in the RC5 coding standard, and the informati...
