| 对基于IP的高级数字视频融合业务的要求 |
随着数字广播业务的迅速发展，许多服务运营商正在考虑这些业务的更有效的传输手段。近来为更有效地使用资源并适应用户的不同需求和环境，数字广播业务已经发生了改变。因此，有必要以在宽带网络环境下保持服务质量（QoS）和有效使用传输带宽为目标，重新定义先进的基于IP的数字视频汇聚业务。 交换数字视频（SDV）业务是在基于射频（RF）的宽带网络上分发数字视频的业务机制，而基于IP的SDV业务是在基于IP的宽带网络上分发数字视频的业务机制。先进的基于IP的数字视频汇聚业务是一种业务机制，用于提供接口和功能，使业务运营商能够通过基于IP的聚合宽带网络向用户提供有服务质量（QoS）保证的广播。 ITU-T J.1111建议书旨在定义基于IP的数字视频汇聚业务的业务要求，包括基于IP的SDV技术，同时考虑到聚合的环境。 ITU-T J.1111建议书规范性地引用了ITU-T J.1101建议书，其描述了基于IP的交换数字视频业务的功能要求。 |
