本发明涉及数字电视技术领域， 具体涉及视频点播业务中信号路由资源 IP流正交幅度调制 (IPQAM, IP Quadrature Amplitude Modulation) /正交幅度 书
调制QAM, Quadrature Amplitude Modulation)资源的分配方法、 终端和服务 器。 背景技术
随着广播电视行业的不断发展， 用户可以根据自己的喜好选择自己感兴 趣的内容进行点播观看，这就要求在把被点播的节目流（声频 /视频节目信号） 发送给视频点播终端设备时能够有指向性。 在视频点播过程中， 点播节目流 发送给视频点播终端的指向性是要求所分配的 IP 流正交幅度调制 (IPQAM, IP Quadrature Amplitude Modulation) /正交幅度调制 (QAM, Quadrature Amplitude Modulation)资源， 即信号路由资源， 能够覆盖视频点播终端， 即 经过 IPQAM/QAM调制播出的信号要能够到达视频点播终端。
在数字电视网络中视频点播 (VOD， Video On Demand)中节目流下发给用 户终端的指向性通过分配的 IPQAM/QAM资源来体现，而实现 IPQAM/QAM 资源分配的主要依据是视频点播终端当前在哪些 IPQAM/QAM 资源的覆盖 之下， 即需要识别视频点播终端的位置。 目前数字电视领域采用静态配置方 案在视频点播服务器***中提供配置功能， 实现视频点播终端设备与视频点 播服务器 IPQAM/QAM资源对应关系的配置管理，相当于固定了视频点播终 端所在的位置。 这样在用户进行节目点播时视频点播服务器根据请求点播的 视频点播终端设备从视频点播终端设备与 IPQAM/QAM 资源关系的静态配 置信息中查找， 从而获得可用于本次点播节目播发的 IPQAM/QAM资源， 即 相当于确定了节目播发到视频点播终端设备的信号路由。 这样限制了视频点 播终端设备只能在固定位置使用， 无法实现漫游； 配置复杂， 视频点播终端 设备 -般很多， 因此该配置关系非常复杂； 当***的规模由小到大时， IPQAM/QAM设备需要下移， 这样配置关系需要重新配置。 发明内容

本发明实施例还提供一种视频点播终端， 所述的终端包括： 探测消息发 送单元， 用于向视频点播服务器发送路由探测消息； 路由列表获取单元， 用 于接收视频点播服务器回复的路由资源列表； 探测流接收单元， 用于根据获 取的路由资源列表中的信号路由资源，接收路由探测流；有效路由判断单元， 用于根据接收到的路由探测流， 判断所述接收到的路由探测流对应的信号路 由资源是否有效； 探测结果报告单元， 用于将有效的信号路由资源上报至视 频点播服务器。
本发明实施例还提供一种视频点播业务中信号路由资源的分配方法， 所 述的方法包括： 接收视频点播终端发送的路由探测消息； 根据接收到的路由 探测消息，发送路由探测流；根据发送的路由探测流所对应的信号路由资源， 生成路由资源列表并发送； 接收视频点播终端发送的路由资源列表中的有效 信号路由资源信息； 根据接收到的有效信号路由资源信息， 生成视频点播终 端与信号路由资源的对应关系
本发明实施例还提供一种视频点播服务器， 所述的服务器包括： 探测消 息接收单元，用于接收视频点播终端发送的路由探测消息；探测流发送单元， 用于根据接收到的路由探测消息， 发送路由探测流； 路由列表生成单元， 用 于根据发送的路由探测流所对应的信号路由资源，生成路由资源列表并发送; 探测结果接收单元， 用于接收视频点播终端发送的有效信号路由资源信息； 路由关系生成单元， 用于根据接收到的有效信号路由资源信息， 生成视频点 播终端与信号路由资源信息的对应关系。
本发明实施例在不变更现有架构的情况下， 通过视频点播终端与视频点 播服务器的配合， 采用信号路由探测的方法， 视频点播终端设备位置的自动 识别以及视频点播终端设备与视频点播服务器 IPQAM/QAM 资源关系的自 动建立。 这样只要有视频点播终端设备接入网络， 即可实现视频点播终端设 备位置的自动识别以及与资源关系的自动建立， 因此不再要求有复杂的关系 配置管理功能， 也就不再要求固定视频点播终端设备的使用位置， 从而很容 易实现视频点播终端设备的漫游。 另外由于视频点播终端设备位置的自动识 别和与资源关系的自动建立是在每次视频点播终端设备启动时自动完成的， 因此当 IPQAM/QAM 资源对视频点播终端设备的覆盖关系变更时也不再需 要额外的处理即可正常支持视频点播业务。 附图说明

步骤 S202， 视频点播终端接收视频点播服务器回复的路由资源列表。 步骤 S203， 视频点播终端从路由资源列表中顺序取一条信号路由资源， 这里信号路由资源可以是 IPQAM/QAM资源。
步骤 S204， 视频点播终端判断是否有 IPQAM/QAM资源要处理。 判断 结果处理如下：
如果能够取到 IPQAM/QAM资源， 则继续后续流程完成路由探测； 如果没有可处理的 IPQAM/QAM资源了， 则转入步骤 S208执行向视频 点播服务器发送探测结果报告；
步骤 S205， 视频点播终端从取到的 IPQAM/QAM资源中获得播发频点 和服务标识， 调谐视频点播终端到该频点， 根据服务标识接收路由探测流， 这里路由探测流可以是传输流 (Transport Stream, TS流)。
