摘要
讨论了在宽带IP信息网上开展标准清晰度电视(SDTV)和高清晰度电视(HDTV)业务所需关键设备DVB-IP网关的系统功能,同时参考PICMG规范提出一种满足所提DVB-IP网关系统设计指标的系统结构体系,该体系结构的优越性体现在:以模块方式完成系统设计功能指标的基础上,符合电信对该网关设备的运营和管理要求。
A specification and architecture with respect to an equipment which is critical to deploy SDTV and HDTV on broadband IP networks are presented . Its architecture is based on PICMG specification. So it has the advantages of flexibility and stability.
