Mixed coding method for remote controlled emitter of TV set

Abstract

A mixed coding method for telecontrol transmitter of TV set has the characters as, corresponding to each function key of the remote controller to edit and transmit a set of 2-20 different formats of coding A, B, C, D... in series connection and combination, to set a gap between the string and string, of which to edit at least twice when the length of a string of origin coding corresponded by A, B, C, D... is less than 100 ms for the other different format coding to be edited at least once to form a mixed coding circulation. The optimum scheme of the prsent invention is to apply 3-5 different format coding to edit continuously at least twice for each coding and also to edit its valid periodical action. The remote controller made by this method not only has a universalization but also has no need to individually set remote coding format.

Description

technical field [0001] The invention relates to a remote control operating system of a TV, in particular to a mixed coding method for a color or black and white TV remote control transmitter (hereinafter referred to as "remote control"). The TV remote controller made by using the mixed coding method has the versatility of one machine, that is, a remote controller with a mixed coding method can be used as a remote controller of multiple TV remote control operating systems in different formats. Background technique [0002] The TV remote controller brings convenience to people watching TV. In the prior art, the coding of the remote control is generally composed of two parts, the first part is the system code, which is commonly referred to as the user code, and the second part is the operation code (also known as the data code). The code will be transmitted in a loop until the key is released. There are various coding formats of the existing remote c...

Problems solved by technology

Such design has certain flaws in practice: 1. When a TV remote controller is damaged and cannot be repaired, it must be equipped with the same type of remote controller, and some models are difficult to be assigned for a while, which will bring consumers Inconvenience; 2. Due to the large variety, types and specifications of TV sets, the wide variety of remote controls on the market brings a lot of inconvenience to production management. On a deeper level, it also causes a waste of social resources

This kind of remote control has dozens or even hundreds of color TV remote control coding formats programmed inside, and it can adapt to a variety of color TV remote control receiving systems with different coding formats. However, the biggest disadvantage of this kind of remote control is that it puts forward higher requirements for users, that is, the user must set it according to the instruction manual when using it for the first time, that is to say, the user must set the remote control according to his own color TV model. The encoding format, moreover, must be reset every time the battery is replaced, otherwise it cannot be used

This is obviously inconvenient for the elderly or some users with low educational level
