举例来讲， 上述实施例的第一种情况可以是会议过程中有新与会者进场， 终端设备向服务器发送会议记录获取请求， 其中， 该会议记录获取请求中包括 第一类型标识， 该第一类型标识可以用于指示服务器获取自会议开始到接收到 会议记录获取请求时记录的会场码流信息作为目标会场码流信息；
上述实施例的第二种情况可以是与会者预约一个时长的会议记录， 终端设 备向服务器发送会议记录获取请求， 其中， 该会议记录获取请求中包括第二类 型标识， 该第二类型标识可以用于指示服务器获取预先约定时间段内的会场码 流信息作为目标会场码流信息。
上述实施例的第三种情况可以是与会者离开会场时， 终端设备向服务器发 送会议记录开始请求， 该会议记录开始请求可以用于指示服务器获取目标会场 码流信息的起始时间； 在一时长后， 与会者重新进入会场， 终端设备向服务器 发送会议记录结束请求， 其中， 该会议记录结束请求可以用于指示服务器获取 目标会场码流信息的结束时间。 具体来讲， 与会者离开会场时， 终端设备接收 到与会者离场指令， 并根据与会者离场指令向服务器发送会议记录开始请求， 在一段时间后， 与会者重新进入会场， 终端设备接收与会者重新进入场指令， 并根据与会者重新进入会场的指令向服务器发送会议记录结束请求。
在本实施例中， 终端设备可以根据智能识别的方式，检测与会者是否离场， 并根据与会者离场信息， 向服务器发送所述会议记录开始请求； 或者， 终端设 备可以根据智能识别的方式， 检测终端设备检测与会者是否重入场， 根据与会 者重入场信息， 向服务器发送会以记录结束请求。
需要说明的是， 终端设备可以根据智能识别的方法或是非智能识别的方法 得到会议记录获取请求， 并将该请求发送给服务器。 举例来讲， 智能识别的方 式可以是终端设备通过人脸检测或是位置检测的方法确定与会者是第一次进入 会场、 再次进入会场或是离场， 本实施例不限制智能识别的方法仅限于人脸检 测或是位置检测， 本实施例同时也不限制具体的检测方法， 检测方法可以是根 据时间不同的两个画面对应的每个像素进行比对，也可以将临近像素划分为块， 并以块为单位进行比对， 本实施例中检测方法的实现可以是本领域相关技术人 员所能实现的任一种实现方法。 非智能识别的方法可以是与会者通过视频会议 界面上显示的对话框进行获取会议记录的选择， 或是通过点击物理按钮， 终端 设备发送会议记录获取请求， 该会议记录获取请求用于指示请求获取的目标会 场码流信息。 例如， 在会场内存在和终端直连的物理按键， 与会者点击该物理 按键， 终端发送生成会议摘要请求给服务器， 与会者再次点击该物理按键， 终 端发送停止生成会议摘要请求给服务器。
步骤 102、 终端设备接收服务器返回的目标会场码流信息， 目标会场码流 信息是服务器根据会议记录获取请求的指示从所记录的会场码流信息中获取 的。

本实施例的方法可以包括：
步骤 201、 服务器接收终端设备发送的会议记录获取请求， 会议记录获取 请求用于指示终端设备获取目标会场码流信息；
具体的， 服务器可以接收终端设备在至少三种情况下发送的会议记录获取 请求， 第一种情况是在会议过程中有新与会者进场， 新进入会场的与会者需要 查看会议开始到与会者进入会场这一时长的会议记录， 于是通过终端设备向服 务器发送会议记录获取请求； 第二种情况是与会者根据需要预约一个时长的会 议记录， 于是通过终端设备向服务器发送该会议记录获取请求； 第三种情况是 与会者在会议过程中中途离场， 在一时长后再次进入会场后， 与会者需要查看 离开会场到再次进入会场这一时长的会议记录， 于是通过终端设备向服务器发 送该会议记录获取请求。 其中， 服务器中存储的会议记录可以是从会议开始到 会议结束的过程中每个会场接收方向的码流， 该码流的存储可以是活动图像的 码流和 /或胶片编码的码流。
在上述实施例的第三种情况下， 与会者离开会场时， 服务器接收终端设备 发送的会议记录开始请求， 会议记录开始请求用于指示服务器获取目标会场码 流信息的起始时间， 服务器接收到会议记录开始请求后开始获取目标会场的码 流信息； 在一段时间后， 与会者重新进入会场， 服务器接收终端设备发送的会 议记录结束请求， 会议记录结束请求用于指示服务器获取目标会场码流信息的 结束时间， 服务器接收到会议记录结束请求后停止获取目标会场的码流信息， 这段时间内获取的码流信息构成所述目标会场码流信息。
在上述实施例的第一种情况下， 在会议过程中有新与会者进场， 服务器接 收终端设备发送的会议记录获取请求 ,该会议记录获取请求包括第一类型标识 , 第一类型标识用于指示服务器获取自会议开始到接收到会议记录获取请求时记 录的会场码流信息作为目标会场码流信息； 服务器同时根据第一类型标识， 获 取从会议开始到接收到会议记录获取请求时记录的会场码流信息作为目标会场 码流信息。
在上述实施例的第二种情况下， 与会者预约一个时长的会议记录， 服务器 接收终端设备发送的会议记录获取请求， 该会议记录获取请求包括第二类型标 识， 第二类型标识用于指示服务器获取预先约定时间段内的会场码流信息作为 目标会场码流信息； 服务器同时根据会议记录中包括的第二类型标识， 获取预 先约定时间段内的会场码流信息作为目标会场码流信息。
步骤 202、 服务器根据会议记录获取请求的指示， 从所记录的会场信息中 获取目标会场码流信息；
步骤 203、 服务器向终端设备发送目标会场码流信息， 以使终端设备播放 目标会场码流信息。
可选的， 服务器可以向终端设备发送会议记录播放询问请求， 以询问终端 设备是否播放目标会场码流信息； 接着， 服务器接收终端设备发送的会议记录 播放响应， 会议记录播放响应用于指示服务器发送目标会场码流信息； 则服务 器根据会议记录播放响应的指示， 向终端设备发送目标会场码流信息。 或者服 务器接收终端设备发送的会议记录拒绝响应， 会议记录拒绝响应用于指示服务 器拒绝发送目标会场码流信息， 则服务器删除目标会场码流信息。
另一种实现方式， 服务器接收终端设备发送的会议记录播放请求， 该会议 记录播放请求用于指示服务器发送目标会场码流信息， 接着服务器根据会议记 录播放请求的指示， 向终端设备发送目标会场码流信息。
本实施例， 通过服务器接收终端设备发送用于指示终端设备请求获取的目 标会场码流信息的会议记录获取请求， 接着， 服务器根据会议记录获取请求的 指示， 从所记录的会场信息中获取目标会场码流信息， 最后服务器向终端设备 发送目标会场码流信息， 以使终端设备播放目标会场码流信息。 使得与会者可 以根据不同的情况获取目标会场码流信息， 从而满足与会者对会议的了解， 进 而提高会议中各与会者的沟通效率。
进一步的， 在上述实施例的步骤 203之后， 服务器为目标会场码流信息打 标签并存储， 标签用于标识目标会场码流信息。
具体的， 服务器根据终端设备发送的会议记录获取请求， 确定是否生成目 标会场码流信息或是结束目标会场码流信息， 同时服务器对目标会场码流信息 打标签。 服务器同时对应存储目标会场码流信息和标签信息。 服务器可以将当 前会议的会议号、 终端设备所在会场的会场号、 目标会场码流信息的生成类型 以及目标会场码流信息的数目索引值作为标签信息；
举例来讲， 服务器从会议开始到会议结束这段时间， 对所有会场的码流进 行统一存储。 服务器确定生成目标会场码流信息， 生成该目标会场码流信息， 服务器同时对该目标会场码流信息打上标签。 打标签的方式可以为： 会议号 + 会场号 +会议摘要类型 +生成的会议摘要数目索引值。 其中， 每个会场的会议号 和会场号由服务器统一分配， 原则上是同一个会议， 会议号相同， 会场号不同； 不同的会议， 会议号不同， 会场号有可能不同。 会议摘要类型有三种： 新与会 者入会而生成的会议摘要； 与会者重新进入会场而生成的会议摘要； 与会者预 约。 会议摘要数目的索引值由服务器统一分配和管理， 原则上由服务器递增生 成。
例如： 新与会者入会而生成会议摘要定义为 01 , 与会者重新进入会场而生 成会议摘要定义为 02, 与会者预约二生成会议摘要定位为 03。 当前只有两个会 场入会， 会场 A和会场 B。 服务器对这两个会场分配的会议号为 0755, 会场号分 别为 001和 002。 会议摘要数目以 1进行递增。 那么 0755+001+01+001则表示： 会 议号为 0755, 会场号为 001的会场有新与会者入会， 因而生成会议摘要， 当前会 议摘要的数目为服务器生成的第一个会议摘要。 0755+002+02+002则表示： 会 议号为 0755, 会场号为 002的会场有与会者重新进入会场， 因而生成会议摘要， 当前会议摘要为服务器生成的第二个会议摘要。
本实施例， 通过服务器根据会议记录获取请求的指示， 从所记录的会场信 息中获取目标会场码流信息， 并且服务器向终端设备发送目标会场码流信息， 以使终端设备播放目标会场码流信息， 以获得会场码流对应的会议内容。 使得 与会者可以根据不同的情况获取目标会场码流信息， 从而满足与会者对会议不 同程度的了解， 进而提高会议中各与会者的沟通效率。
下面采用几个具体的实施例 ,对上述方法实施例的技术方案进行详细说明。 图 3为本发明会议记录获取和提供方法实施例一的流程图， 如图 3所示， 本实施例的会议至少包括 1个会场， 同时接入会场的个数可以由 MCU的接入 能力确定， 并且每个会场向 MCU发送一路码流并接收一路码流。 本实施例的 会场和 MCU之间的连接可以是基于 H323协议， 也可以是基于 SIP协议。
