本文主要介绍了基于DVB标准EN 300 468的Mosaic视频导航系统。Mosaic是一种利用多个视频图像组合进行节目导航的机制,可以把它看成是一种高级的电子节目指南。文章先介绍了Mosaic节目视频导航机制的原理,然后分析了Mosaic描述符的数据结构,并补充必要的私有描述符,最后给出实现方法概要。

This paper mainly introduces the Mosaic Guidance System based on DVB Standard. A mosaic component is a collection of different video images to form a video component in order to offer convenient guidance, so it can be regarded as advanced electronic program guidance. Firstly, this paper introduces the principle of the mosaic system, then analyzes the data structure of the mosaic descriptor with some private definitions, and, presents the software designation and method of realization in the end.
