| IPTV业务的业务发现和选择机制 |
ITU-T H.770建议书介绍了业务提供商发现、业务发现和IPTV业务选择的机制。该机制使IPTV终端设备能够向终端用户提供消费IPTV业务的有效方式。采用业务发现信息的IPTV业务类型预计包括线性电视（TV）和视频点播（VoD）等。 此份建议书确定了提供有关业务提供商和内容/服务及同时涉及单播和组播转送机制的传送协议的业务发现元数据要素和属性。 此份2015年版建议书还在第7.1段增加了如何处理“Web门户URL”的注释，并修改了“门户URL”和“元数据服务器URL”的实例，将它们转变为“ ://[:]/”。在第10段中，本建议书增加了“元数据服务器URL”的实例。此外，在第10.1和10.2段中，“首选内容指导发现记录位置”被更改为“首选内容指导发现记录”，相应的实例亦更改为布尔值。附录II中的相关要素/属性也进行了修改。这一版本的建议书还在表7.1-4种增加了一种新的业务类型，“部件业务”。 |
