Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] The design idea of ​​the remote control decoding error-tolerant method proposed by the present invention is: when the remote control key code received by the TV CPU is a repeated key code, a tolerance value is given, and when the bit error rate of the remote control decoding does not exceed the tolerance value When the value is set, set the key value of the key that has an error code to the key value corresponding to the key key that was pressed last time, so as to solve the problem of frequent misoperation of the TV due to external interference that causes code errors in the remote control decoding; When the code rate exceeds the tolerance value, set the key value of the key that has an error code as the key value corresponding to no key operation, so as to avoid misoperation of the TV. The bit error rate is the number of cons...

Abstract

The invention discloses a remote control decoding fault-tolerance method. When the received remote control key-pressing code is a repeated key-pressing code, a tolerance value is given. When the code error rate of the remote control decoding is lower than the tolerance value, the key-pressing value with code error is set as the key-pressing value corresponding to the last key-pressing. When the code error rate of the remote control decoding is higher than the tolerance value, the key-pressing value with code error is set as the key-pressing value corresponding to no operation of key-pressing. Thus false action of the TV set can be prevented. In the invention, the fault-tolerance design is added to the remote control decoding software, namely, certain tolerance for code error is provided. When the code error rate is lower than the tolerance value, the key-pressing is considered as repeated; when the code error rate is higher than the tolerance value, no key-pressing is believed to occur until the key is released. The tolerance value is determined according to the light or electromagnetic wave disturbance degree in the environment, thus the remote control reliability of the TV set is effectively improved and false action of the TV set is prevented, which is good for promoting the whole quality of the TV set.

Description

technical field [0001] The invention belongs to the technical field of remote control decoding, and in particular relates to an error-tolerant method for preventing code errors in remote control decoding. Background technique [0002] At present, for remote controllers using NEC codes, according to the characteristics of NEC remote codes themselves: only repeat codes are sent when pressing keys continuously. In this case, external interference such as light and electromagnetic waves can easily cause Bit errors, resulting in decoding errors. If it is not dealt with, it will cause a malfunction of the TV, thereby affecting the normal use of the user and reducing the overall quality of the TV product. Contents of the invention [0003] In order to solve the problem in the prior art that external interference causes code errors in the remote control decoding and causes TV malfunctions, the present invention provides a new type of remote control decoding error-tolerant method,...
