摘要
数字电视技术的发展和电视业务多元化的趋势,为互动电视业务的开展提供了基础条件和市场动力。通过在电视终端加入交互功能,人们不但可以收看电视节目,还能够完成在线游戏、阅读资讯、电视购物等。互动电视应用业务涉及到发送端和接收端如何交换和表现多媒体数据的问题,也就是数据以何种格式编码传输和以何种机制解析并显示在电视屏幕上的问题,这一问题的解决就需要制定标准和规范来进行约定,这样才能够解决应用兼容性问题,实现跨平台开发,MHEG标准的制定正好满足了这样的需求。介绍应用于互动电视中的MHEG标准的组成和作用,分析MHEG-5标准的内容体系,阐述MHEG-5内容编辑的方法和MHEG-5应用的框架,对我国制定互动电视标准具有一定的参考价值。
