Method and apparatus for responding remote signals of remote receiving equipment

Abstract

The invention discloses a method and an apparatus for responding remote signals of remote receiving equipment. The method comprises the steps of integrating at least two remote controller protocols in a drive layer of remote signal receiving equipment; generating remote controller key code value mapping table in an application layer of the remote signal receiving equipment; decoding the remote signals by the drive layer according to the integrated remote controller protocols after the remote signal receiving equipment receives the remote signals, so as to obtain real key code value of the remote controller; then searching the mapping key code value corresponding to the real key code value in the remote controller key code value mapping table; and transmitting the mapping key code value to the application layer so as to execute a key function. With the hierarchical design of integrating a plurality of controller protocols in the drive layer and generating the remote controller key code value mapping table in the application layer, the apparatus can respond the remote signals with various protocols; and software in the drive layer is in no need of frequent modifications, so that the stability of the system is enhanced; and cost for software development and maintenance is reduced.

Description

technical field [0001] The invention relates to a remote control signal processing technology, in particular to a remote control receiving device and a remote control signal response method and device. Background technique [0002] At present, remote control receiving devices capable of receiving infrared remote control signals, such as set-top boxes, are more and more widely used in families. Due to the variety of these devices and the characteristics of different users, different manufacturers have carried out strict codes for the remote controllers that emit infrared remote control signals. These codes are different, thus forming different coding methods, called infrared remote control signals. Remote control encoding transmission protocol. At present, there are more than a dozen infrared remote control protocols in the market, and the commonly used ones are NEC, RC5, and SIRC protocols. [0003] Taking set-top boxes as an example, infrared remote control is one of the ...

AI Technical Summary

Problems solved by technology

If the set-top box application market increases, the types of remote control protocols used to support the increase will increase. If each remote control corresponds to a decoding software, software developers will need to develop and maintain multiple versions of decoding software. This will not only increase the number of developers. The development time and debugging burden also increase the maintenance cost of product software, which is not conducive to the improvement of the market competitiveness of set-top box products
