本文介绍了一种多任务分屏显示技术，主要涉及多线程编程与多媒体解码显示的总体软件架构及其在嵌入式异步全彩LED显示控制系统中的应用。采用该技术实现的多视图LED显示系统，可以将单个大屏或长条屏任意分割成多个区域的小屏，每种区域分割方式构成一种布局，多种布局可在播放过程中随时随意切换；且区域间相互独立，各区域可同时播放各种相同或不同的多媒体对象，每个媒体对象都有多种进出场特效供选择。

This paper introduces a multi-tasking split view technique, mainly involves the overall architecture of multithread programming including decoding and displaying of multimedia, and its application in embedded asychronous full color LED display control system. In multi-view LED display system using the technique, a single large screen or a long LED bar display can be divided into multiple small regions, and each region segmentation method describes a layout, a variety of layouts can be switched at any time during display. Besides, all the regions are independent of each other, each region can play all kinds of the same or different multimedia objects at the same time, and each media object has multiple special effects for choice.
