Description

一种基于MOST的多环网流媒体多播系统和方法 技术领域
本发明涉及流媒体技术领域，尤其涉及一种基于MOST的多环网流媒体多播系统和方法。
背景技术
流媒体技术是近几年来针对Internet上多媒体信息的有效传输而发展起来的多媒体通信技术。流媒体以其边下载边播放的特点，不但除去了用户漫长的下载等待烦扰，而且极大降低了对系统存储容量的需求。
它广泛应用于互联网上的多种信息服务，成功地为各项应用进行有效的多媒体信息传输。
由视频传输需求提出，旨在实现流式多播传输和实时播放。媒体流的带宽占用分为两部分：一部分是多媒体数据；另一部分是传输、播放控制信息。
流式传输时，声音、影像或动画等多媒体信息由流媒体服务器向用户计算机连续、实时传送，它首先在使用者端的电脑上创建一个缓冲区，于播放前预先下载一段资料作为缓冲，用户不必等到整个文件全部下载完毕，而只需经过几秒或十数秒的启动延时即可进行观看。当多媒体信息在客户机上播放时，文件的剩余部分将在后台从服务器内继续下载。如果网络连接速度小于播放的多媒体信息需要的速度时，播放程序就会取用先前建立的一小段缓冲区内的资料，避免播放的中断，使得播放品质得以维持。流式传输除了能够发送已经制作完成的文件外，还可以通过采集服务器实时采集现场音视频， 推送到流媒体服务器端，实时提供给用户。因此，流媒体除了能够更好的承担如下载一样的多媒体点播服务外，更能够应用在现场直播、电视转播、突发事件报道等多种对实时性传输要求较高的领域。

本发明的目的在于提供一种能够提高服务器和网络线路利用率的一种基于MOST的多环网流媒体多播系统和方法。
为了解决上述技术的问题，本发明采用的技术方案是：一种基于MOST的多环网流媒体多播系统，包括MOST主机以及n个MOST环网，每个MOST环网内包括n个终端节点设备，各终端节点设备和MOST主机节点之间通过光纤线串行连接，所述MOST环网通过所述MSOT主机实现互联互通。
作为本发明一个优选实施方式，所述系统还包括支持组播技术的路由器。
作为本发明一个优选实施方式，所述系统还包括媒体服务器，所述媒体服务器由MOST主机、存储系统和流媒体服务软件组成。
本发明还提供了一种基于MOST的多环网流媒体多播方法，包括MOST主机以及n个MOST环网，每个MOST环网内包括n个终端节点设备，各终端节点设备和MOST主机节点之间通过光纤线串行连接，所述MOST环网通过所述MSOT主机实现互联互通；
当收到MOST网络通信接口模块发送过来的终端用户服务消息后，所述MOST主机从存储系统中读取相应的内容，发送到指定的组；
MOST服务器将一组客户请求的流媒体数据发送到支持组播技术的路由器上，然后由所述路由器将所述流媒体数据根据路由表复制到多个通道 上，再向用户终端发送；
终端按照自各所在的组别，从MOST网络中获得所要的数据流，并将获取到的数据流送至终端播放器，实现流媒体的播放。
作为本发明一个优选实施方式，在终端按照自各所在的组别，从MOST网络中获得所要的数据流，并将获取到的数据流送至终端播放器，实现流媒体的播放之后，还包括当收到MOST网络通信模块发过来的终端用户请求的结束指令时，所述MOST主机与给定的用户组断开，关闭此进程。
作为本发明一个优选实施方式，在当收到MOST网络通信模块发过来的终端用户请求的结束指令时，所述MOST主机与给定的用户组断开，关闭此进程之后，还包括各终端根据自身需要，决定加入相应的组，以获取对应的流媒体内容。
附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部分，并不构成对本发明的不当限定，在附图中：
图1为本发明系统框图。
图2为本发明流媒体多播方法框图。
具体实施方式
下面将结合附图以及具体实施例来详细说明本发明，在此本发明的示意性实施例以及说明用来解释本发明，但并不作为对本发明的限定。
参考附图1，一种基于MOST的多环网流媒体多播系统，包括MOST主机以及n个MOST环网，每个MOST环网内包括n个终端节点设备，各终端 节点设备和MOST主机节点之间通过光纤线串行连接，所述MOST环网通过所述MSOT主机实现互联互通。
MOST主机：一种基于linux平台的节点设备，集成了多路MOST网络通信控制单元模块，主要负责各流媒体文件的读取、转发。
终端1...n：一种MOST网络节点设备，集成了显示和触摸控制功能，集成了MOST网络通信控制单元。
各终端节点和MOST主机节点之间通过光纤线串行连接，流媒体文件通过光纤线送达各节点。
各环网通过MOST主机实现互联互通，实现终端与终端之间、终端与MOST主机的信息交换。
系统利用MOST环网搭建了TCP/IP服务，这是实现IP多播技术的基础。
具体的，所述系统还包括支持组播技术的路由器。
具体的，所述系统还包括媒体服务器，所述媒体服务器由MOST主机、存储系统和流媒体服务软件组成。
服务器主机(MOST主机)：服务器主机性能是衡量一个流媒体服务系统的重要指标,选择运行稳定并拥有足够的带宽的服务器主机是流媒体服务系统的关键。
存储系统：流媒体服务器中存储的电影等各种视频文件数量很大,所以需要的存储空间相对较大。考虑到文件系统本身的开销和系统容错,实际的容量需求会更多。大容量的数据存储系统是基本的要求,更需要系统具有良好的容错性能,并具有足够的稳定性,在发生部分数据错误时,系统可以恢复和重建数 据,而不至于影响系统的正常运行。
参考附图2，本发明还提供了一种基于MOST的多环网流媒体多播方法，包括MOST主机以及n个MOST环网，每个MOST环网内包括n个终端节点设备，各终端节点设备和MOST主机节点之间通过光纤线串行连接，所述MOST环网通过所述MSOT主机实现互联互通；
当收到MOST网络通信接口模块发送过来的终端用户服务消息(包括用户的地址)后，所述MOST主机从存储系统中读取相应的内容，发送到指定的组；
MOST服务器将一组客户请求的流媒体数据发送到支持组播技术的路由器上，然后由所述路由器将所述流媒体数据根据路由表复制到多个通道上，再向用户终端发送；这时候，媒体服务器只需要发送一个信息包，所有发出请求的客户端都共享同一信息包，并且信息可以发送到任意地址的客户机(终端)，没有请求的客户机(终端)不会收到信息包，网络上传输的信息包的总量没有广播那么多，大大提高了服务器和网络线路的利用率。
终端按照自各所在的组别，从MOST网络中获得所要的数据流，并将获取到的数据流送至终端播放器，实现流媒体的播放。
作为本发明的一个具体实施方式，在终端按照自各所在的组别，从MOST网络中获得所要的数据流，并将获取到的数据流送至终端播放器，实现流媒体的播放之后，还包括当收到MOST网络通信模块发过来的终端用户请求的结束指令时，所述MOST主机与给定的用户组断开，关闭此进程。
作为本发明的一个具体实施方式，在当收到MOST网络通信模块发过来的终端用户请求的结束指令时，所述MOST主机与给定的用户组断开，关闭此进程之后，还包括各终端根据自身需要，决定加入相应的组，以获取对应 的流媒体内容。
以上对本发明实施例所提供的技术方案进行了详细介绍，本文中应用了具体个例对本发明实施例的原理以及实施方式进行了阐述，以上实施例的说明只适用于帮助理解本发明实施例的原理；同时，对于本领域的一般技术人员，依据本发明实施例，在具体实施方式以及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本发明的限制。
