IPTV服务的轻量级互动多媒体环境(LIME) |
ITU-T H.762建议书描述了用于IPTV的轻型互动多媒体环境(LIME)的高层功能。LIME向IPTV终端设备功能提供支持,以提供互动性和音频、视频、图形和文本等多种内容。预计提供的服务包括丰富电视节目的文本以及双向门户网页等附加数据。
本建议书描述了被称为XHTML 1.0 W3C建议书的“LIME-HTML”详细资料、被称为“LIME-CSS”级联样式表1(CSS1)的详细资料、CSS2的一部分,即称为“LIME-DOM”的文件对象模型(DOM)的详细资料,以及被称为“LIMe-Script”的作为ECMAScript子集,但具有IPTV服务所需功能扩展的脚本语言。它描述了利用基于IP的协议传送LIME和IPTV相关服务的情况。
这一修改包括增加解释性案文和定义,以提高可读性和人们对扩展功能的了解。具体的考虑是将“BML”串改为“LIME”,并增加对浏览器伪对象方法的说明。这些变化并没有改变已为人们所接受的功能,也没有采用任何新功能。
