| 二次分配的IPTV业务要求和框架 |
当今的电信业致力于开发新一代电视服务、通常称为IPTV,及凭借IP网络技术在整个融合网络基础设施上传送综合语音、数据和视频三合一业务。电缆业具有通过光纤/铜轴(HFC)混合网络成功提供视频业务并通过DOCSIS和IPCablecom增加数据和语音支持的悠久历史。 ITU-T J.700建议书描述了IPTV机制的使用,并试图经现有的基于电缆的二次分配网络和/或其它网络支持IPTV业务,以加强现有的电视分配服务。经修改的本建议书进一步明确了它与ITU-T Y.1910建议书之间的IPTV架构的关系,并对业务提供商接口的关系重新做了说明。此外,还提及了光纤射频传输(RFoG)、经光纤的波长复用视频传输和HFC及光纤的混合使用等最新的二次分配接入网络技术。此修订还旨在提供一系列编辑性修改。 |
