Reserved timing system and performing method thereof

Abstract

This invention relates to a preengaged timing system including a digital signal receiver for receiving and transferring a digital signal containing current time, a first connector, a LC TV controller coupled to the digital signal receiver via the first interface to pick up the current time and operate it with preengaged time to generate rest time, a second connection interface and an inserted controller including a real time frequency circuit, a nonvolatile memory unit and an O / I unit coupled to the controller via the second connection interface, which rceives the rest time and outputs a trigger signal to an electronic device when the time is counted to a definite time value, and the real time frequency circuit is used in counting the rest time and the nonvolatile memory unit is used to store the time.

Description

technical field [0001] The present invention relates to a reservation timing system and its execution method, and particularly relates to a reservation timing system suitable for liquid crystal televisions. Background technique [0002] Due to the advantages of not occupying space, light weight, power saving, long life, and no electromagnetic waves, LCD TVs are becoming more and more popular. In order to increase the added value of the LCD TV, a timer function is usually added so that the user can perform some preset functions. For example, the user can use the scheduled timer function to automatically turn on and off the machine or record TV programs, or activate other multimedia devices such as DVD recorders and so on. However, in order to add a group of pre-scheduled functions, it is usually necessary to add additional circuits and components to the hardware circuit design to achieve the purpose, which not only increases the overall cost, but also makes the hardware desi...

Problems solved by technology

However, in order to add a set of pre-scheduled functions, it is usually necessary to add additional circuits and components to the hardware circuit design to achieve the purpose, which not only increases the overall cost, but also makes the hardware design more complicated.

Especially when more sets of appointment timing functions or other additional functions are required, hardware circuits and components may need to be replaced at the same time, making its scalability very limited

In addition, if you want to keep the reserved parameters, you need an additional memory unit to ensure that the reserved parameters will not disappear, which will also cause increased cost and inconvenience in design
