Key processing method, device and system

Abstract

An embodiment of the invention discloses a key processing method, device and system. The method includes setting mapping relations between a key code and a rapid code value event as well as a normal code value event; determining a key state of a user according to the key code and a preset time window if an operating object corresponding to the key code is a multi-screen selection application when the key code is received; mapping the key code into the rapid code value event according to the mapping relations if the determined key state is a rapid key state; processing the multi-screen selection application according to the rapid code value event to complete response to inter-screen mobile selection. By the key processing method, device and system, on the premise that hardware cost is not increased, one key for two codes can be realized, in other words, one key code corresponds to two code value events and executes two response events; simplicity and convenience in user operation are realized, misoperation is avoided, and mobile selection for intra-screen programs and inter-screen programs during processing of multiple screens can be easily realized.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a key processing method, device and system. Background technique [0002] Audio and video display terminal devices represented by TVs and set-top boxes mainly use remote control buttons to obtain key codes, and execute corresponding key code value events, that is, one key performs one process, such as the left key moves to the left, the right key moves to the right, etc. If you want to increase the direct button function unit, you need to increase the number of buttons. However, increasing the number of keys means increasing equipment costs. [0003] At the same time, terminal equipment provides more and more display and operation content. For example, when there are multiple screens in the classified TV program selection scene, there are program selection operations within the screen and program selection operations between screens. If you select one by one with a s...

However, increasing the number of keys means increasing the cost of equipment

[0003] At the same time, terminal equipment provides more and more display and operation content. For example, when there are multiple screens in the classified TV program selection scene, there are program selection operations within the screen and program selection operations between screens. If you select one by one with a single button, the user The operation is complex and prone to misoperation, and the user experience effect is poor
