多线程技术在条件接收系统中的应用
Multi-threading technology applicationin the Conditional Access system
为满足宽带互动电视对DVB广播和IPTV点播业务的需求,实现条件接收系统中视音频的实时传输,另外考虑到单进程效率低下,多进程额外负担较大等因素,本文采用了Win32多线程技术。本文所提出的一种基于事件驱动的三缓冲区多线程结构,能够更充分地利用CPU资源,更有效地提高条件接收系统处理视音频的速率,从而保证了用户点播的视音频的实时性传输。本文详细介绍了条件接收系统中的多线程设计思想,并最后通过系统运行实例给出了其可行性验证。
In this paper,to meet the broadband interactive TV on the DVB broadcast and IPTV on-demand business needs, achieve real-time video and audio transmission in the conditional access systems, while taking into account the low efficiency of a single process, the larger additional burden of multi-process, we use the Win32 multi-threading technology.The proposed three multi-threaded structure,based event-driven,could make better use of CPU resources, improve the rate of video and audio in Conditional Access system . It ensure that video and audio could be transmitted real-time. This paper describes multi-threading design ideology in the conditional access system , and finally verify its feasibility by running the system program.(10 Points, Times New Roman)
