Multi-application management method and device based on Linux set-top box, and terminal

Abstract

The invention provides a multi-application management method and a multi-application management device based on a Linux set-top box, and a terminal. According to the multi-application management method, a program at a stack top of a program management stack is confirmed as a current foreground program according to a first-in last-out operation principle of the program management stack, thereby facilitating reasonable allocation of system resources; by adopting a method of configuring a Z order value of the foreground program as a height value of the program management stack, the Z order valueof the foreground program can be ensured to be the maximum Z order value of all current active programs, thereby ensuring that the foreground program is displayed at the forefront of a screen; and when an application located at the bottom layer of the program management stack is switched to the foreground program, the maximum Z order value can be obtained by pushing the application into the stackagain without activating or shutting down the program, thereby realizing rapid switching among a plurality of applications. In addition, the main program is responsible for the management of the plurality of applications without relying on a third-party program library, thereby enabling rapid integration and porting of management programs.

Description

technical field [0001] The present disclosure relates to the technical field of set-top boxes, and in particular to a Linux-based set-top box-based multi-application management method, device and terminal. Background technique [0002] With the diversification of business needs, most current set-top box products support multi-process mode, and users can start multiple applications at the same time when using the set-top box. For example, in addition to starting the main application program used to implement the basic services of the set-top box, the user can also simultaneously open secondary application programs such as a browser to browse web page information, stock information, etc. Since multiple applications share memory resources and display resources, in order to avoid conflicts among multiple applications, effective management of multiple applications is very necessary. [0003] At present, the set-top box lacks unified management of applications, which is likely to...
