需要说明的是， 可以不在视频请求中包含用于请求获取所述视频数据对应 的 PTZ操作信息的指示信息， 而是所有的视频请求都是默认用于请求获取视频 数据及其对应的 PTZ操作信息的， 则监控平台在接收到所述视频请求后， 无需 判断所述视频请求中是否包含用于请求获取所述视频数据对应的 PTZ操作信息 的指示信息， 而是可以直接判断所述第一监控终端对应的用户是否具有获取所 述视频数据对应的 PTZ操作信息的权限。
如果判断结果为是， 执行步骤 230A; 如果判断结果为否， 执行步骤 230B。 步骤 230A: 监控平台获取所述视频数据对应的 PTZ操作信息， 并向所述第 一监控终端发送所述视频数据和获取的 PTZ操作信息， 以使得所述第一监控终 端在播放所述视频数据时同步展示所述 PTZ操作信息， 所述 PTZ操作信息用于 描述对所述监控前端设备的云镜执行的操作；

需要说明的是， 步骤 230A的具体实现可以是， 生成所述视频数据的获取地 址（如 URL )和所述 PTZ操作信息的获取地址（如 URL )发送给所述第一监控终 端， 接收第一监控终端发送的包含所述视频数据的获取地址的请求， 根据所述 视频数据的获取地址与所述第一监控终端建立用于发送所述视频数据的媒体通 道， 根据所述视频数据的获取地址获取所述视频数据并通过所述媒体通道发送 所述视频数据； 接收第一监控终端发送的包含所述 PTZ操作信息的获取地址的 请求， 根据所述 PTZ操作信息的获取地址与所述第一监控终端建立用于发送所 述 p t z操作信息的媒体通道， 根据所述 PTZ操作信息的获取地址获取所述 p t z 操作信息并通过所述媒体通道发送所述 p t z操作信息。步骤 230B的具体实现同 步骤 230A中发送视频数据的具体实现， 不再赘述。

前提： CU1的用户通过 CU1对 PU的拍摄区域进行实时视频监控
具体地， PU向监控平台的 MU发送实时拍摄的视频数据， MU将接收的视频 数据转发给 CU1 , CU1播放该视频数据。具体可以通过 RTP协议传输该视频数据。
需要说明的是， 在实时视频监控期间， MU会一直接收 PU拍摄发送的视频 数据，并将接收的视频数据转发给对该 PU的拍摄区域进行实时视频监控的监控 终端 （如， 本示例实施方式中的 CU1和 CU2所在的监控终端）。

<xs: complexType name="PTZOperat ion" >
<xs: complexType name="UserInfo">
<xs: element name=" ID" type="xs: int"/>
</ xs: complexType>
<xs: complexType name="PTZInfo">
<xs: element name="DeviceID" type="xs: int"/>
<xs: element name="Date" type="xs: date"/>
<xs: element name="Time" type="xs: time"/>
<xs: element name="PTZ0pCode" type="xs: string"/>
</xs: complexType>
</ xs: complexType> 其中， PTZOperation元素用于记录 PTZ操作信息， 包括子元素 Userlnfo 和 PTZInfo。 其中， Userlnfo元素用于记录执行该 PTZ操作的用户的信息， 包 括用于记录用户标识的 ID子元素； PTZInfo元素用于记录 PTZ操作的描述信息， 包括用于记录前端设备标识的 Device ID子元素、 用于记录操作日期的 Date子 元素、用于记录操作时间的 Time子元素和用于记录操作动作的 PTZOpCode子元 素。
步骤 402: CU1向监控平台的 SU发送该 HTTP报文；
步骤 403: SU从接收到的 HTTP ^艮文中提取 xm 1格式的 PTZ操作信息； 步骤 404: SU根据 PTZ操作信息中的操作人员的标识从用户信库中获取该 操作人员的描述信息， 如， 操作人员的名字、 所在部门、 账户类型、 地址等信 息。
步骤 405: SU将步骤 404获取的操作人员的描述信息合并到步骤 403中提 取的 PTZ操作信息中；
合并后的 XML格式的 PTZ操作信息示例如下：
<xs: complexType name="PTZOperat ion" >
<xs: complexType name="UserInfo">
<xs: element name=" ID" type="xs: int"/>
<xs: element name="Name" type="xs: string"/>
<xs: element name="Level " type="xs: string" use="opt ional " /> <xs: element name="Depar tment " type="xs: string" use="opt ional "/>
<xs: element name=" Address " type="xs: string" use="opt ional "/> </ xs: complexType>
<xs: complexType name="PTZInfo">
<xs: element name="DeviceID" type="xs: int"/>
<xs: element name="Date" type="xs: date"/>
<xs: element name="Time" type="xs: time"/>
<xs: element name="PTZ0pCode" type="xs: string"/>
</ xs: complexType>
</xs: complexType>
其中， Userlnfo元素包括用于记录用户姓名的 Name子元素、 用于记录用 户级别的 Level子元素、用于记录用户部门的 Department子元素和用于记录用 户地址的 Address子元素。
步骤 406: SU将合并生成的 xml格式的操作信息通过 TCP或 UDP协议发送 给 MU。
步骤 407: MU緩存收到的 xml格式的 PTZ操作信息， 并将緩存的 PTZ操作 信息通过 RTP协议传输给 CU1;
优选地，可以将緩存的 PTZ操作信息以元数据 metadata格式（如字幕文件 格式）封装后封装在 RTP包中传输给 CU1。
步骤 408: CU1播放接收的视频数据时同步展示该 PTZ操作信息；
