Description

融合的互联网协议IP视频系统及实现方法 技术领域
本发明涉及通信领域，具体而言，涉及一种融合的互联网协议IP视频系统及实现方法。
背景技术
目前相关技术中存在两个体系的视频系统：(a)广电系的符合ComCast公司制定的新一代视频点播的基本架构(Next Generation On Demand Video Architecture称为NGOD)的规范的交互式电视点播(Video On Demand简称为VOD)系统，(b)电信运营商体系的互联网协议(Internet Protocol简称为IP)视频系统。
对于NGOD VOD系统而言核心是视频点播服务，不过可以将架构进行扩展来支持其它的点播服务。图1是相关技术中NGOD VOD系统的结构框图，如图1所示，该NGOD VOD系统的核心组件包括：
1.业务管理系统(Business Management System简称为BMS)--用于用户、产品、策略管理等。
2.导航服务器—设置为为点播应用获取其他组件的必需的信息，如资产元数据，导航服务器提供导航菜单和相关应用属性给点播客户端并同点播客户端交换信息来激活导航功能。
3.会话管理器(Session Manager简称为SM)--设置为为点播服务管理会话生命周期。
4.点播资源管理器(On Demand Resource Manager简称为ODRM)--设置为分配和管理推流服务器的流资源。
5.边缘资源管理器(Edge Resource Manager简称为ERM)--设置为分配和管理边缘设备上所需的资源，如正交振幅调制(Quadrature Amplitude Modulation简称为QAM)带宽。
6.点播客户端—定义为数字机顶盒或任何可以提供代理服务来同NGOD进行交互的网关服务器上的一个模块收集器。
7.边缘设备—设置为接收从IP传输网络通过UDP/IP传送过来的多同态图像专家组(Moving Picture Experts Group简称为MPEG)单节目传输流(Single-Program  Transport Stream，简称为SPTS)，转成MPEG多节目传输流(Multi-Program Transport Stream，简称为MPTS)，并且生QAM调制信号。
8.推流服务器—通过传输网络和边缘设备将数字视频流向数字机顶盒。
9.内容分发网络(Content Delivery Network简称为CDN)--从媒资系统获取、存储媒体文件，向推流服务器发送媒体码流。
二、IP视频系统是利用宽带网，集互联网、多媒体、通讯等技术于一体，向家庭用户提供包括数字电视在内的多种交互式服务。图2是相关技术中IP视频系统的结构框图，如图2所示，该IP系统的核心组件包括：
1.业务管理系统BMS，为IP视频系统提供业务管理、运营管理、系统管理等功能。业务管理部分主要包括：用户管理、CP/SP(Content Provider/Service Provider)管理、产品/服务管理、资源管理、门户服务。其中产品数据可以来源于外部BOSS系统的产品信息同步，也可以直接由系统内部创建产品。系统提供产品、服务和内容的关联关系，为运营管理所服务。运营管理部分主要包括：认证、鉴权、计费结算、统计分析等功能。运营管理部分可以向BOSS提供相应接口实现IP视频业务管理与运营支撑。系统管理负责系统角色和权限管理、终端管理等。
2.内容管理系统(Content Management System，简称为CMS)--位于内容运营层，其主要功能是负责所有接入IP视频业务系统的CP/SP、运营商自营业务元数据、内容运营、EPG、播出控制等各方面与业务内容相关管理。同时，CMS内容管理平台还需要负责不同CP/SP、运营商自营业务间的内容二次制作、打包、审核、发布等功能。经过内容管理平台处理后的IP视频业务内容可直接由业务运营层提供服务。
3.内容分发系统CDN，主要完成内容分发/传送功能、内容存储功能、调度/控制功能、统计数据采集和质量监控功能。它由CDN全局控制功能和CDN节点所组成。其中CDN全局控制功能负责对CDN节点进行管理，而CDN节点则承担媒体服务功能。
4.电子节目菜单(Electronic Program Guide，简称为EPG)，EPG系统作为IP视频系统的门户系统，主要完成和用户的接口，用户命令的解析和交互并将结果发回给用户。IP视频系统所提供的各种业务的索引及导航都是通过EPG系统来完成的。EPG系统的界面与Web页面类似，在EPG界面上一般都提供各类菜单、按钮、链接等可供用户选择节目时直接点击的组件；EPG的界面上也可以包含各类供用户浏览的动态或静态的多媒体内容。
5.IP视频系统终端，主要是IP机顶盒+电视机、PC，也可以是手机或者移动便携电子设备。
当前业界存在的现状是NGOD VOD系统和IP视频系统分属不同的领域和技术体系，两个系统的内容资源不能共享给普通大众用户。
针对相关技术中上述问题，目前尚未提出有效的解决方案。
