本公开涉及多媒体通讯技术领域，具体地，涉及一种多媒体会议终端的控制方法及多媒体会议服务器。
视频会议系统中的终端分为两类，即，硬件终端与软件终端。硬件终端由于移动性比较差，一般放在会议室中，但是稳定性与清晰度比较好，并可以采用高清电视作为输出。软件终端则一般安装在手机、PAD(平板电脑)、笔记本等设备上，移动性比较好，但是稳定性与清晰度一般。在实际的会议系统中，存在多个软件终端与硬件终端同时加入同一个会议的场景。
在视频会议系统中每个会议都会根据自身的情况占用一定的系统资源，包括带宽资源、视频编解码资源等等，同时还可能包括会议室资源。通常，一个会议室对应一个硬件终端，并且若干个参加会议的人员可以同时出现在同一个会议室。
通常，管理会议或者会议室资源的方式是，通过用户或者管理员提前预约会议与会议相关的会议室，并且在预约时间段内由预约用户使用。由于用户往往并不清楚会议实际需要的持续时间，所以为了保证会议的顺利进行，会尽量多地预约一些时间。因此，如果会议就会提前结束，则会议资源与会议室由于被占用而造成资源浪费。在这样的管理方式下，会议室与会议的资源利用率不高。

为使本公开的技术方案和优点更加清楚，下面将结合附图和实施例对本公开进行详细描述。
本公开的说明书和权利要求书中的术语“第一”、“第二”等 是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便这里描述的本公开的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。
图1为根据本公开实施例的多媒体会议终端的控制方法的流程图。
参见图1，根据本公开实施例的多媒体会议终端的控制方法可以包括步骤S101至S103。
在步骤S101，判断多媒体会议终端采集的会议现场的多媒体信息是否符合预定条件。如果不符合预定条件，则执行步骤S102；如果符合预定条件，则执行步骤S103。
在本公开实施例中，多媒体信息可包括第一多媒体信息和为了防止误关闭而采集的第二多媒体信息。第一多媒体信息是多媒体会议终端从会议现场采集到的，第二多媒体信息是在判定第一多媒体信息符合预定条件后在指定的时间段内从会议现场采集到的。第一多媒体信息和第二多媒体信息均可为音频信息和/或视频信息。需要说明的是，第一多媒体信息和第二多媒体信息类型可以相同也可以不同，例如，第一多媒体信息为音频信息时，第二多媒体信息可为音频信息和/或视频信息。
根据本公开实施例，步骤S101可以包括：判断多媒体会议终端采集的会议现场的第一多媒体信息是否符合第一预定条件；如果所述第一多媒体信息不符合第一预定条件，则判定所述多媒体信息不符合预定条件；如果所述第一多媒体信息符合第一预定条件，则在所述多媒体会议终端上显示通知信息并判断多媒体会议终端采集的会议现场的第二多媒体信息是否符合第二预定条件；如果所述第二多媒体信息不符合第二预定条件，则判定所述多媒体信息不符合预定条件；如果所述第二多媒体信息符合第二预定条件，则判定所述多媒体信息符合预定条件。
如上所述，第一多媒体信息和第二多媒体信息可为音频信息和/或视频信息，因此，判断多媒体会议终端采集的会议现场的多媒体信 息是否符合预定条件可以包括以下几种情况：
情况一：第一多媒体信息和第二多媒体信息均为音频信息
如果第一多媒体信息的音量小于预设的第一音量阈值，且第一多媒体信息的音量小于预设的第一音量阈值所对应的第一状态的第一持续时间超过预设的第一时间阈值，则判定第一多媒体信息符合第一预定条件；如果第二多媒体信息的音量小于预设的第二音量阈值，且第二多媒体信息的音量小于预设的第二音量阈值所对应的第四状态的第四持续时间超过预设的第四时间阈值，则判定第二多媒体信息符合第二预定条件。当第一多媒体信息符合第一预定条件且第二多媒体信息符合第二预定条件时，可判定多媒体信息符合预定条件，以关闭多媒体会议终端。
情况二：第一多媒体信息和第二多媒体信息均为视频信息
如果不能从第一多媒体信息中识别出人像，且不能从第一多媒体信息中识别出人像所对应的第二状态的第二持续时间超过预设的第二时间阈值，则判定第一多媒体信息符合第一预定条件；如果不能从第二多媒体信息中识别出人像，且不能从第二多媒体信息中识别出人像所对应的第三状态的第三持续时间超过预设的第三时间阈值，则判定第二多媒体信息符合第二预定条件。当第一多媒体信息符合第一预定条件且第二多媒体信息符合第二预定条件时，可判定多媒体信息符合预定条件，以关闭多媒体会议终端。
情况三：第一多媒体信息为音频信息且第二多媒体信息为视频信息
如果第一多媒体信息的音量小于预设的第一音量阈值，且第一多媒体信息的音量小于预设的第一音量阈值所对应的第一状态的第一持续时间超过预设的第一时间阈值，则判定第一多媒体信息符合第一预定条件；如果不能从第二多媒体信息中识别出人像，且不能从第二多媒体信息中识别出人像所对应的第三状态的第三持续时间超过预设的第三时间阈值，则判定第二多媒体信息符合第二预定条件。当第一多媒体信息符合第一预定条件且第二多媒体信息符合第二预定条件时，可判定多媒体信息符合预定条件，以关闭多媒体会议终端。
情况四：第一多媒体信息为视频信息且第二多媒体信息为音频信息
如果不能从第一多媒体信息中识别出人像，且不能从第一多媒体信息中识别出人像所对应的第二状态的第二持续时间超过预设的第二时间阈值，则判定第一多媒体信息符合第一预定条件；如果第二多媒体信息的音量小于预设的第二音量阈值，且第二多媒体信息的音量小于预设的第二音量阈值所对应的第四状态的第四持续时间超过预设的第四时间阈值，则判定第二多媒体信息符合第二预定条件。当第一多媒体信息符合第一预定条件且第二多媒体信息符合第二预定条件时，可判定多媒体信息符合预定条件，以关闭多媒体会议终端。
情况五：第一多媒体信息和第二多媒体信息均为音频和视频信息
如果第一多媒体信息的音量小于预设的第三音量阈值且不能从第一多媒体信息中识别出人像，并且第一多媒体信息的音量小于预设的第三音量阈值且不能从第一多媒体信息中识别出人像所对应的第五状态的第五持续时间超过预设的第五时间阈值，则判定第一多媒体信息符合第一预定条件；如果第二多媒体信息的音量小于预设的第四音量阈值且不能从第二多媒体信息中识别出人像，并且第二多媒体信息的音量小于预设的第四音量阈值且不能从第二多媒体信息中识别出人像所对应的第六状态的第六持续时间超过预设的第六时间阈值，则判定第二多媒体信息符合第二预定条件。当第一多媒体信息符合第一预定条件且第二多媒体信息符合第二预定条件时，可判定多媒体信息符合预定条件，以关闭多媒体会议终端。
在本公开实施例中，判断多媒体会议终端采集的会议现场的多媒体信息是否符合预定条件的具体实现方式并不仅限于以上列举的五种情况，以上五种情况只是示例。可以理解的是，在本公开实施例中并不具体限定判断多媒体会议终端采集的会议现场的多媒体信息是否符合预定条件的具体实现方式。
在步骤S102，获取多媒体会议终端采集的会议现场的多媒体信息。
在步骤S103，关闭多媒体会议终端。
根据本公开实施例，在接收到多媒体会议终端采集的会议现场的多媒体信息后，首先判断多媒体会议终端采集的会议现场的多媒体信息是否符合预定条件。当所述多媒体信息符合预定条件时，可以关闭多媒体会议终端，从而可以提高资源利用效率，其中包括系统资源与会议室资源。
为了便于理解多媒体会议终端的控制方法的流程，以下针对上述情况一所例举的情况进行具体说明。
如果终端采集的音频数据的输入能量在某一时间段内始终小于某个正常值且识别不出人声音，则可以认为该终端目前没有人发言，并且处于可关闭状态。在此情况下，可以在会议控制页面或者终端列表页面显示通知信息，以通知该多媒体会议终端即将被关闭。此后，如果探测到采集的音频数据发生了变化，则使终端恢复为正常状态，并重新开始上述过程；如果探测到采集的音频数据始终表示识别不出人声音，则可以关闭该多媒体会议终端。
图2为根据本公开另一实施例的多媒体会议终端的控制方法的流程图，即，图2示出了上述判断过程。
参见图2，根据本公开另一实施例的多媒体会议终端的控制方法可以包括步骤S201至S209。
在步骤S201，判断所述第一多媒体信息的音量是否小于预设的第一音量阈值。如果所述第一多媒体信息的音量大于或等于预设的第一音量阈值，则判定所述第一多媒体信息不符合第一预定条件并执行步骤S208；如果所述第一多媒体信息的音量小于预设的第一音量阈值，则执行步骤S202。
在步骤S202，确定所述第一多媒体信息的音量小于预设的第一音量阈值所对应的第一状态的第一持续时间。
在步骤S203，判断所述第一持续时间是否超过预设的第一时间阈值。如果所述第一持续时间超过预设的第一时间阈值，则执行步骤S204；如果所述第一持续时间未超过预设的第一时间阈值，则判定所述第一多媒体信息不符合第一预定条件并执行步骤S208。
在步骤S204，在所述多媒体会议终端显示通知信息。
在步骤S205，判断所述第二多媒体信息的音量是否小于预设的第二音量阈值。如果所述第二多媒体信息的音量大于或等于预设的第二音量阈值，则判定所述多媒体信息不符合预定条件并执行步骤S208；如果所述第二多媒体信息的音量小于预设的第二音量阈值，则执行S206。
在步骤S206，确定所述第二多媒体信息的音量小于预设的第二音量阈值所对应的第四状态的第四持续时间。
在步骤S207，判断所述第四持续时间是否超过预设的第四时间阈值。如果所述第四持续时间超过预设的第四时间阈值，则判定所述第二多媒体信息符合第二预定条件(即，所述多媒体信息符合预定条件)并执行步骤S209；如果所述第四持续时间未超过预设的第四时间阈值，则判定所述第二多媒体信息不符合第二预定条件并执行步骤S208。
在步骤S208，获取多媒体会议终端采集的会议现场的多媒体信息。
在步骤S209，关闭所述多媒体会议终端。
类似地，对于上述涉及视频信息的情况二而言，如果终端采集的视频数据在某一时间段内始终识别不出人像，则可以认为该终端所在会场没有人员，并且该终端处于可关闭状态。在此情况下，可以在会议控制页面或者终端列表页面显示通知信息，以通知该多媒体会议终端即将被关闭。此后，如果探测到采集的视频信息发生了变化，则使终端恢复为正常状态，并重新开始上述过程；如果探测到采集的信息始终表示识别不出人像，则可以关闭该多媒体会议终端。
例如，与上述情况二所对应的多媒体会议终端的控制方法可以包括：判断是否能从所述第一多媒体信息中识别出人像。如果能够从所述第一多媒体信息中识别出人像，则判定所述第一多媒体信息不符合第一预定条件(即，所述多媒体信息不符合预定条件)；如果不能从所述第一多媒体信息中识别出人像，则确定不能从所述第一多媒体信息中识别出人像所对应的第二状态的第二持续时间，并且判断所述 第二持续时间是否超过预设的第二时间阈值。如果所述第二持续时间未超过预设的第二时间阈值，则判定所述第一多媒体信息不符合第一预定条件(即，所述多媒体信息不符合预定条件)；如果所述第二持续时间超过预设的第二时间阈值，则在所述多媒体会议终端显示通知信息，并判断是否能从所述第二多媒体信息中识别出人像。如果能从所述第二多媒体信息中识别出人像，则判定所述第二多媒体信息不符合第二预定条件(即，所述多媒体信息不符合预定条件)；如果不能从所述第二多媒体信息中识别出人像，则确定不能从所述第二多媒体信息中识别出人像所对应的第三状态的第三持续时间，并判断所述第三持续时间是否超过预设的第三时间阈值。如果所述第三持续时间超过预设的第三时间阈值，则判定所述第二多媒体信息符合第二预定条件(即，所述多媒体信息符合预定条件)；如果所述第三持续时间未超过预设的第三时间阈值，则判定所述第二多媒体信息不符合第二预定条件(即，所述多媒体信息不符合预定条件)。在判定所述多媒体信息不符合预定条件的情况下，可以继续获取多媒体会议终端采集的会议现场的多媒体信息；在判定所述多媒体信息符合预定条件的情况下，可以关闭所述多媒体会议终端。
类似地，对于上述涉及音频信息和视频信息的情况五而言，根据本公开实施例的多媒体会议终端的控制方法可以包括：判断所述第一多媒体信息的音量是否小于预设的第三音量阈值以及是否能从所述第一多媒体信息中识别出人像。如果所述第一多媒体信息的音量大于或等于预设的第三音量阈值或者能从所述第一多媒体信息中识别出人像，则判定所述第一多媒体信息不符合第一预定条件(即，所述多媒体信息不符合预定条件)；如果所述第一多媒体信息的音量小于预设的第三音量阈值并且不能从所述第一多媒体信息中识别出人像，则确定所述第一多媒体信息的音量小于预设的第三音量阈值且不能从所述第一多媒体信息中识别出人像所对应的第五状态的第五持续时间，并判断所述第五持续时间是否超过预设的第五时间阈值。如果所述第五持续时间未超过预设的第五时间阈值，则判定所述第一多媒体信息不符合第一预定条件(即，所述多媒体信息不符合预定条件)； 如果所述第五持续时间超过预设的第五时间阈值，则在所述多媒体会议终端显示通知信息，并判断所述第二多媒体信息的音量是否小于预设的第四音量阈值以及是否能从所述第二多媒体信息中识别出人像。如果所述第二多媒体信息的音量大于或等于预设的第四音量阈值或者能从所述第二多媒体信息中识别出人像，则判定所述第二多媒体信息不符合第二预定条件(即，所述多媒体信息不符合预定条件)；如果所述第二多媒体信息的音量小于预设的第四音量阈值且不能从所述第二多媒体信息中识别出人像，则确定所述第二多媒体信息的音量小于预设的第四音量阈值且不能从所述第二多媒体信息中识别出人像所对应的第六状态的第六持续时间，并判断所述第六持续时间是否超过预设的第六时间阈值。如果所述第六持续时间超过预设的第六时间阈值，则判定所述第二多媒体信息符合第二预定条件(即，所述多媒体信息符合预定条件)；如果所述第六持续时间未超过预设的第六时间阈值，则判定所述第二多媒体信息不符合第二预定条件(即，所述多媒体信息不符合预定条件)。在判定所述多媒体信息不符合预定条件的情况下，可以继续获取多媒体会议终端采集的会议现场的多媒体信息；在判定所述多媒体信息符合预定条件的情况下，可以关闭所述多媒体会议终端。
根据本公开实施例，通过判断是否能从多媒体会议终端采集的第一多媒体信息中识别出人像和/或判断第一多媒体信息的音量是否小于预设的音量阈值，并且判断不能从第一多媒体信息中识别出人像和/或第一多媒体信息的音量小于预设的音量阈值的持续时间是否超过预设的时间阈值，来初步判断多媒体会议终端采集的会议现场的多媒体信息是否符合预定条件。当初步判定多媒体信息符合预定条件时，在多媒体会议终端显示通知信息，以通知该多媒体会议终端即将被关闭。此后，如果在一定的时间段内从多媒体会议终端采集的第二多媒体信息中依旧不能识别出人像和/或第二多媒体信息的音量依旧小于预设的音量阈值，则关闭所述多媒体会议终端，以提高资源利用效率，其中包括系统资源与会议室资源。
