Description

一种发现流媒体业务的方法和系统以及业务发现装置 技术领域
本发明涉及多媒体技术领域， 特别涉及一种发现流媒体业务的方法 和系统以及业务发现装置。 发明背景
流媒体业务是近几年迅速发展的一种新业务， 流媒体业务利用流式 传输技术在包交换网络上传输多媒体文件， 包括视频、音频等文件内容， 这些内容在访问时无需完全下载就可以立即播放。 流式传输技术把连续 的视频和音频信息经过处理后放到网络中的业务服务器上， 让用户边下 载边观看、 收听， 而不需要等整个文件下载到自己的机器后才可以观看 的网络传输技术。
在流媒体业务中， 一般需要向用户提供一个电子节目单或者具有类 似功能的服务， 该节目单为用户导航， 让用户了解当前可以提供的业务 或者月良务； 该节目单也可以指引用户进行节目订阅， 引导用户触发业务 等。 所述提供电子节目单的过程称为流媒体业务的发现过程。
目前采用的发现流媒体业务的系统如图 1所示， 图 1为现有技术中 发现流媒体业务的系统结构图。 其中， 营销单元 101用于向电子节目单 ( EPG )服务器 102提供节目信息； EPG服务器 102用于根据营销单元 101 提供的节目信息生成电子节目单， 并提供给用户终端 103; 业务服 务器 104用于向用户终端提供节目内容。
具体执行过程为：用户终端 103首先需要获知 EPG服务器 102的地 址， 通过该地址访问 EPG服务器 102, 并请求 EPG服务器 102。 EPG服 务器 102接到请求后向用户终端 103发送电子节目单。 用户终端 103根 据电子节目单中提供的节目内容的地址手动设置连接业务服务器 104获 取节目内容。
虽然上述流媒体业务的发现方法适合于现有的 IP网络，并对于支持 SIP 的终端也可以适用， 但是该方法的业务发现机制不灵活， 用户每次 要获得节目单时， 需要获知 EPG服务器的地址并主动发起请求， EPG 服务器接收到请求后才会根据请求中用户的地址向用户发送电子节目 单， 而并不能自动发送电子节目单， 用户终端获取电子节目单地实施过 程比较麻烦， 这就带来了较差的用户体验， 上述发送电子节目单的过程 也就是发现流媒体业务的过程。 所以现有技术中还没有一种能够自动发 现流媒体业务的方法， 能给用户带来较好的用户体验。 发明内容
