Description
Technical Field
The invention relates to an intelligent television technology, in particular to a technology for decoding a plurality of remote controllers of an android intelligent television.
Background
With the overall steady growth of the android smart television market in these years, various smart television manufacturers have also made differentiated designs of their product functions and configurations in various sales channels. Therefore, for the same chip scheme, it is more and more common to need to match the remote controllers suitable for the channels adopted by the chip, and currently, the remote control decoding part is completed in the Kernel part in the software flow, so that the Kernel part needs to be controlled in the software flow to complete the differential change.
At present, there are two methods for ensuring the decoding of remote control codes supporting various remote controllers, one is that many complete machine manufacturers can separate the adaptive remote control part according to the macro definition compiling isolation mode, and compile a Kernel software version corresponding to the remote control code of each supported remote controller, but this increases the compiling cost and the software maintenance cost, and is very easy to cause the human error of software configuration; secondly, the remote control code parts of the remote controllers supported by all kinds are added to the Kernel part (both the remote control code parts can be supported), so that although the software can support the decoding of the remote control codes of various remote controllers by one version, the software cannot separate and isolate the remote control codes of the remote controllers of different kinds, and further the effective isolation of the functional parts of the sales channel is influenced, for example, at a certain sales counter, two customers respectively use different remote controllers to control the same television.
Disclosure of Invention
The invention aims to solve the problems that the existing method for decoding the remote control codes of various remote controllers is high in cost or the remote control codes of various remote controllers cannot be isolated and supported, and provides a method for decoding the remote control codes compatible with the multiple remote controllers.
The present invention is applied to the above-described method of decoding remote control codes supporting various kinds of remote controllers in which the remote control code sections of all kinds of supported remote controllers are added to the Kernel section.
The invention solves the technical problem, adopts the technical scheme that the method for decoding the remote control code compatible with a plurality of remote controllers is characterized by comprising the following steps:
step 1, reserving a data space of programmable storage equipment in host equipment hardware, and respectively storing decoding types corresponding to remote controllers to be supported according to a predetermined number;
step 2, setting the number of the decoding type corresponding to the remote controller which needs to be supported at this time in a boot bootstrap program in a Bootrags mode, and taking the number of the decoding type as the state of the remote controller;
and 3, when the Kernel is started, transmitting the state of the remote controller to the Kernel, analyzing the decoding type corresponding to the remote controller required to be supported in the Kernel in an early _ param mode, selecting a part required to be supported in the IR decoding program according to the decoding type corresponding to the remote controller required to be supported in the current time, and not selecting the rest parts, so that the remote controller required to be supported in the current time can only be responded.
Specifically, in step 1, the programmable storage device is an EEPROM.
The method has the advantages that the decoding method compatible with the remote control codes of the multiple remote controllers is compatible with decoding of the multiple remote controllers, control confusion can not be caused due to the fact that only the remote controllers needing to be supported are responded each time, and the method is simple in software and low in cost.
