摘要
目前,有线电视传输系统并不是真正意义上的数字电视系统,绝大多数已经使用的机顶盒只具有标清解码能力,满足不了用户的需求。未来高清晰数字电视机顶盒将是用户观看数字高清晰度电视节目的主要设施。介绍高清晰度数字电视机顶盒的结构,对数字电视机顶盒关键技术解复用技术进行了研究,分析了高清晰度电视解复用实现的过程,提出解复用的软件流程设计。
In the course of development of digital television technology,the application of the high-definition digital TV set-top box is an important trend.The high definition digital television is a complex system,in which the demultiplexing is the reverse process of digital multiplexing.It restores the digital HD source signals transmitted by channels and is one of the key technologies of digital television.The demultiplexing technology for digital HDTV is analyzed,and explains its realization process is elaborated.The procedure design of the demultiplexing software is proposed.
