用户的单播类节目播放出现异常时， 可以确定出故障节目基本信息， 此 故障节目基本信息包括： 故障节目名称、 故障用户账号、 相关的 STB设备信 息、 用户观看的故障节目名称、 故障发生时间、 故障持续时间等。 通过故障 节目基本信息可以确定故障节目所属的媒体服务器信息以及故障节目在媒体 服务器上的媒体文件。
步骤 102 , 根据所述出口媒体指标数据判断所述媒体服务器是否存在故 障或者所述媒体服务器上的媒体文件是否存在故障。 出口媒体指标数据是指丟包率， 网络抖动参数等。
将媒体服务器作为播放源播放所述出现异常的节目称为故障节目 , 将另 一处于正常状态的媒体服务器或测试设备作为接收端， 接收所述故障节目， 进行播放抓包测试后计算出所述出口媒体指标数据。
出口媒体指标数据异常时， 判定媒体服务器的媒体出口网络存在故障； 出口媒体指标数据正常并且对所述故障节目进行播放测试发现播放异常时 (例如播放不流畅或音视频不同步等情况 ),判定所述媒体服务器上的媒体文 件存在故障。
步骤 102中所述媒体服务器正常并且所述媒体服务器上的媒体文件正常
的情况下， 上述方法中还可以包括以下检测步骤：
质量数据， 如果服务质量数据正常， 则判定机顶盒存在故障， 如果服务质量 数据异常， 则判定机顶盒正常， 需进一步判断用户至媒体服务器之间的线路 或设备是否存在故障。
步骤 103中， 机顶盒正常的情况， 上述方法还可以包括以下检测步骤： 步骤 104, 判定用户的接入设备是否存在故障。
将用户的接入设备按离用户从近到远的距离划分为 N级接入设备， N 2, 优选地， N为 3 , 因为通常将离用户最近的接入设备确定为第一级接入设 备， 离用户最远的接入设备确定为第三级接入设备， 中间的所有接入设备确 定为第二级接入设备。 下面以将接入设备分别三级为例来进行说明。 第一级 接入设备例如 DSLAM, ONU等， 第二级接入设备即汇聚所述第一级接入设 备的网络设备例如汇聚交换机， 第三级接入设备即与承载网相邻的接入设备 例如 BRAS、 SR等。
如图 2所示包括以下步骤：
步骤 201 , 判断与用户同属于第三级接入设备的其它用户在相同时段接 收的与故障节目相同或近似带宽的节目的服务质量数据是否异常，如果异常， 判定第三级接入设备故障或第三级接入设备与媒体服务器之间的线路存在故 障， 如果正常， 判定第三级接入设备与用户之间的线路或设备存在故障。
其中， 推断出第三级接入设备故障或第三级接入设备与媒体服务器之间 线路故障， 并且其他第三级接入设备都存在大面积类似故障， 则推断出相关 第三级接入设备上联网络设备故障。
步骤 202 , 判定第三级接入设备与用户之间的线路或设备存在故障的情 况下， 判断与用户同属于第二级接入设备的其它用户在相同时段接收的与故 障节目相同或近似带宽的节目的服务质量数据是否异常， 如果异常， 判定第 二级接入设备故障或第二级接入设备与第三级接入设备之间的线路存在故 障， 如果正常， 判定第二级接入设备与用户之间的线路或设备存在故障。
步骤 203 , 判定第二级接入设备与用户之间的线路或设备存在故障的情
况下， 判断与用户同属于第一级接入设备的其它用户在相同时段接收的与故 障节目相同或近似带宽的节目的服务质量数据是否异常， 如果异常， 判定第 一级接入设备故障或第一级接入设备与第二级接入设备之间的线路存在故 障， 如果正常， 判定第一级接入设备与用户之间的线路或设备存在故障。
上述方法中， 通过不同的层次的定位故障分析， 最终确定故障原因， 缩 短了 IPTV运营商的故障处理时间，提高了最终用户的满意度。本发明实施例 方法在进行故障定位中， IPTV服务质量管理***的相关指标数据获取以及分 析推导过程都是***自动完成， 无需运维人员人工干预， 极大的提高了 IPTV 运营商的运维保障能力。
本发明中上述故障检测顺序是较优的检测顺序， 也可以釆用其它顺序或 方式， 例如步骤 101和步骤 102组成的检测试方式； 步骤 101、 步骤 102和步 骤 103组成的检测方式； 步骤 101 , 102, 104组成的检测方式等， 步骤 103 和步骤 104中的故障检测方法也可以单独使用。
与上述方法对应的对单播类节目播放异常进行故障定位的***中包括服 务质量管理服务器， 此服务质量管理服务器可以兼容已有的服务器， 也可以 是新设立的专用服务器，由此服务质量管理服务器完成上述方法所示的功能。
