Abstract
The invention discloses an infrared remote control protocol for controlling a set-top box for a user remote control device, and relates to the technical field of interactive digital televisions. At a set-top box user home, a plurality of electric appliances are provided with infrared remote control devices for supporting the infrared remote control protocols so that the infrared protocol of the set-top box frequently conflicts with the infrared protocols of the electric appliances. At present, a set of infrared coding-targeted unified standard does not exist at home and abroad, and the coding formats defined by manufacturers may be the same. Any coding format on the market is not adopted in the protocol, a set of coding format is totally customized, and the protocol comprises guide codes, ending codes and the like which have different formats as other infrared codes, so the code interference problem can be furthest solved. The code interference rate of the protocol is low and is about 0.0001 percent.
Description
Technical field
The present invention relates to open interactive television field, particularly relate to the remote control agreement of TV-set top box.
Background technology
In set-top box users man, there are a lot of electric equipments to have infrared remote-control device, support the infrared remote control agreement.This often generator top box infrared protocol conflict with the infrared protocol of these electrical equipment, or the remote controller of set-top box can control other electrical equipment, or the remote controller of other electrical equipment can the controller top box, do not wish the result that produces thereby produce the user.Its reason is: at present international and domestic a cover is not at the unified standard of infrared coding, the mode that each producer generally takes is to adopt popular on the market coded format, customer number and key is partly done changed the back and form own one and overlap coded format.Just because of infrared coding does not have unified industry standard at present, the coded format of each producer oneself definition has probability identical phenomenon to occur, so may cause different electrical equipment, the problem of string sign indicating number appears in the infrared coding between the different vendor.So-called string sign indicating number, when just operating some remote controllers, except corresponding equipment responded, other equipment also responded simultaneously.The appearance of this phenomenon will have influence on us and use a teleswitch normally and control various electrical equipment in the family.Solve this problem so be badly in need of a kind of extremely low infrared protocol of code check of going here and there.
Summary of the invention
The objective of the invention is to solve suchlike set-top box infrared remote control agreement and the conflicting problem of household electrical appliance.When pressing the button of remote controller, remote controller will send a string binary code, and we claim that it is frame data.These frame data are made of according to certain rules guidance code, customer number (can be a plurality of), numeric data code (can be a plurality of), check code, end code etc. usually.The present invention does not adopt any coded format on the market, and a fully self-defined cover coded format comprises guidance code, and end code etc. are all different with other infrared coding form in interior various piece, the appearance of solution string sign indicating number problem that like this can maximum possible.
The string code check of this agreement is low, is about 0.0001%.
Carrier frequency is 38K.
Coded format is:
First frame: first guidance code+user code+second guidance code+key+54ms time-delay.
Repeating frame: duplication code+100.16ms time-delay, length is 108ms.
After sending first frame, before button loosens, send repeating frame.
Frame structure is as shown in Figure 1:
First guidance code=3640us (high level)+1800us (low level); " high level " is the infra-red carrier modulation, and " low level " is no infra-red carrier modulation.
8 of user codes (24)=8+yard 1 (C:43H) 8+yard 2 (N:4EH) of sign indicating number 0 (O:4FH);
Second guidance code=3640us (high level)+1800us (low level)
Duplication code=3640us (high level)+3640us (low level)+560us (high level); " high level " is the infra-red carrier modulation, and " low level " is no infra-red carrier modulation.
Key (16)=numeric data code 0 (8)+numeric data code 1 (8);
Data 1=560us (high level)+1120us (low level);
