Man-machine interaction asynchronous control method and device used for terminal

Abstract

The invention provides a man-machine interaction asynchronous control method and a man-machine interaction asynchronous control device used for a terminal. The man-machine interaction asynchronous control method comprises the steps that: after a user operation request is received by an UI (User Interface) application, if it is judged that a background task application does not have a uncompleted user operation response task at present, a control message corresponding to the user operation request is transmitted to the background task application; after the control message is received by the background task application, a corresponding user operation response task is executed according to the user operation request corresponding to the control message, wherein detection steps are set beforeat least one of execution steps contained by the user operation response task, the detection steps comprise: judging whether the UI application receives a new user operation request; when it is judged that the UI application receives the new user operation request, stopping executing a current user operation response task and executing a new user operation response task, wherein the new user operation response task is used for responding to the new user operation request received by the UI application.

Description

technical field [0001] The present disclosure relates to a terminal user interface, and in particular to a method and device for asynchronously controlling human-computer interaction of a terminal. Background technique [0002] At present, many electronic products have human-computer interaction functions. Taking smart TV as an example, smart TV is a TV product to meet the diversified and individual needs of users. Based on Internet (Internet) application technology, it has an open operating system and chip, and an open application platform. Entertainment, data and other functions are integrated to realize two-way human-computer interaction functions, such as human-computer interaction through the buttons of the remote control and the operation methods of up, down, left, and right. [0003] At present, electronic products with human-computer interaction function put forward higher and higher requirements on the response speed of human-computer interaction. It is hoped that ...

Problems solved by technology

If the user continuously presses the channel increment switching key 5 times within 1 second, according to the above-mentioned prior art scheme, such as figure 1 As shown, the UI thread sends 5 control messages within 1 second (such as figure 1 Control message 1 to control message 5) in the control message, in the process of the background task thread responding to each control message, it mainly includes obtaining the basic parameters of playing, frequency locking for playing, and starting the program mapping table (Program MapTable, PMT) search and wait for PMT table data to return, set audio and video parameters, obtain certificate decryption key to start audio and video data descrambling and other steps, these steps take a long time, the total time from receiving the control message to responding to the completion of the control message It can reach 1 second (that is, the total time for responding to a channel switching operation is 1 second), so the total time for responding to 5 control messages is 5 seconds, that is, the background task thread needs 5 seconds to respond Completed the user's last channel switch operation

If the user keeps pressing the channel increment switch key within 1 second, dozens of control messages may be sent within that 1 second, so that it will take longer to respond to the user's last channel switch operation
