Embodiment Construction

[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0045] The solution of the embodiment of the present invention is mainly: by reading the current value of the register corresponding to the infrared remote control, and obtaining the system time difference between the system clock corresponding to the current read operation and the system clock corresponding to the last read operation, according to the current value As well as the system time difference, identify whether there is an encoding error. If so, first perform encoding error correction processing, fill in the discarded key value, and then perform encoding and decoding processing after completion, thereby improving the decoding reliability of the infrared remote control. Through the technical solution of the embodiment of the invention, the problem of low decoding reliability of the infrared remote control is s...

Abstract

The invention discloses an infrared remote control decoding method, comprising: reading a current value of a register corresponding to infrared remote control; acquiring a system time difference between a system clock corresponding to a current reading operation and the system clock corresponding to a previous reading operation; recognizing whether encoding errs according to the current value andthe system time difference; if yes, carrying out encoding error correction; encoding and decoding after encoding error correction. The invention also discloses an infrared remote control decoding device and a computer-readable storage medium. The infrared remote control decoding method and device and the computer-readable storage medium provide improved reliability for infrared remote control decoding.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an infrared remote control decoding processing method, device and computer-readable storage medium. Background technique [0002] Infrared remote control is a wireless operation method commonly used by some household appliances such as set-top boxes and TVs. Remote control will involve remote control encoding and decoding. There are many common encodings for infrared remote control. The most commonly used is the NEC protocol, but there are also some other countries. Defined protocols such as RC5, RC6, RCMM, etc. The encoding of the NEC protocol is relatively standardized. Generally, devices such as set-top boxes support hardware decoding directly, and no software is required to decode; but for some uncommon protocols such as RC5, RC6, and RCMM, general chips do not support hardware decoding. Requires software decoding. The boot is the most basic software for an item b...
