AVS是具有自主知识产权的先进的视音频编解码标准,包含系统-广播、视音频编码及IP网络环境等九大部分。中间件是实现数字电视交互业务不可或缺的软件平台,针对AVS标准,中间件主要涉及其第一和第八部分。因此,建立面向AVS标准的中间件体系结构,是一件有意义的也是非常必要的工作,本文对此作了较为深入的研究与探讨。
AVS is an advanced video and audio codec standard with independent intellectual property rights, covering nine major parts of system-broadcast, video and audio coding and IP network environment. Middleware is an indispensable software platform for digital television interactive services. For AVS standards, middleware mainly involves the first and eighth parts. Therefore, the establishment of middleware architecture for AVS standards is a meaningful and necessary work, this article made a more in-depth study and discussion.
