附图说明
此处所说明的附图用来提供对本发明的进一步理解，构成本申请的一部分，本发明的示意性实施例及其说明用于解释本发明，并不构成对本发明的不当限定。在附图中：
图1所示为本发明实施例1的数据流控系统结构图；
图2所示为本发明实施例2的又一数据流控系统结构图；
图3所示为本发明实施例3的数据流控设备结构图；
图4所示为本发明实施例4的数据流控设备结构图。
具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
图1所示为本发明实施例1的数据流控系统结构图，包括信息资源管理平台、多个数据流控设备、流媒体服务器；其中，所述多个数据流控设备分别与所述信息资源管理平台、所述流媒体服务器相连。
图2所示为本发明实施例2的又一数据流控系统结构图，包括信息资源管理平台、流媒体服务器、多个数据流控设备，其中，所述信息资源管理平台通过所述流媒体服务器分别与所述多个数据流控设备相连。
下面结合图1和图2进行详细说明：
图1和图2中的多个数据流控设备构成数据流控设备集群，在该集群中，多个数据流控设备之间通过流媒体服务器进行信息交互。
在实际部署或应用时，数据流控设备可以是直录播教室、同步课堂、在线课堂、网络课堂或网络教育平台。
同样，在实际部署或应用时，流媒体服务器可以是单个流媒体服务器，还可以是由多个流媒体服务器组成的分布式(各个地方)、多层级(例如：县、市、省)流媒体服务器集群，在该集群中，流媒体服务器包括但不限于：县级流媒体服务器、区级流媒体服务器、市级流媒体服务器、省级流媒体服务器、国家级流媒体服务器。
信息资源管理平台通过流媒体服务器从一个或多个数据流控设备中获取信息资源(如图2所示)或者
信息资源管理平台直接从一个或多个数据流控设备中获取信息资源(如图1所示)
例如：若数据流控设备为直录播教室，则直录播教室将录制的教学资源通过流媒体服务器上传至信息资源管理平台或者直录播教室将录制的教学资源直接上传至信息资源管理平台。
在实际应用过程中，信息资源管理平台不仅具有信息资源管理功能(可以是各个数据流控设备上传的信息资源，还可以是自身配置的信息资源)，还具有 对各个数据流控设备进行监控的功能。
若信息资源管理平台通过流媒体服务器分别与多个数据流控设备相连(如图2所示)，则信息资源管理平台按照预设监控策略，通过流媒体服务器，分别对一个或多个数据流控设备进行监控，其中，所述预设监控策略包括：随机查看一个或多个数据流控设备、查看优先级等级小于预设优先等级的数据流控设备、查看访问次数小于第一预设值的数据流控设备，这大大降低了教学管理者教学管理的负担。
其中，所述预设优先等级、所述第一预设值根据实际情况进行设定，在此不用于限定本发明的保护范围。
数据流控设备进行信息输出时作为信息输出数据流控设备按照获取的预设交互对象分配策略，确定对应的一个或多个接收信息的数据流控设备即信息输入数据流控设备并通过流媒体服务器向一个或多个信息输入数据流控设备提供输出的信息。
例如：若数据流控设备为直录播教室，则直录播教室进行信息输出时作为信息输出直录播教室(也即主课堂)按照获取的预设交互对象分配策略，确定对应的一个或多个接收信息的直录播教室即信息输入直录播教室(也即辅课堂)并通过流媒体服务器向一个或多个信息输入直录播教室提供输出的信息；其中，主课堂可以向一个辅课堂或者向多个辅课堂提供输出的信息。
所述预设交互对象分配策略包括信息输出数据流控设备与信息输入数据流控设备对应关系，如下表所示：
信息输出数据流控设备与信息输入数据流控设备对应关系表
Figure PCTCN2015074892-appb-000001
表1
各个数据流控设备获取预设交互对象分配策略的方式包括：
各个数据流控设备自身配置预设交互对象分配策略、各个数据流控设备分别从信息资源管理平台中获取预设交互对象分配策略、各个数据流控设备分别从流媒体服务器中获取预设交互对象分配策略。
信息输出数据流控设备对信息输入数据流控设备通过所述流媒体服务器发送的信息接入请求按照预设授权审核策略进行授权审核并通过所述流媒体服务器向授权审核通过的信息输入数据流控设备提供输出的信息。
例如：在实际应用中，若数据流控设备为直录播教室，与信息输出直录播教室(也即主课堂)对应的信息输入直录播教室(也即辅课堂)的选取，还可以是以下方式：
信息输出直录播教室(也即主课堂)运行时，对信息输入直录播教室(也即辅课堂)通过流媒体服务器发送的信息接入请求按照预设授权审核策略进行授权审核并通过流媒体服务器向授权审核通过的信息输入直录播教室(也即辅课堂)提供输出的音视频信息。
通过对辅课堂的信息接入请求进行授权审核，实现了灵活的接入控制，大大方便了主课堂的教学管理。
信息输出数据流控设备接收信息输入数据流控设备通过流媒体服务器发送的信息接入请求后，直接向或通过流媒体服务器向信息资源管理平台转发信息接入请求；
信息资源管理平台对信息接入请求按照预设授权审核策略进行授权审核直接向或者通过流媒体服务器向信息输出数据流控设备反馈授权审核通过的信息输入数据流控设备；
信息输出数据流控设备通过流媒体服务器向授权审核通过的信息输入数据流控设备提供输出的信息。
例如：在实际应用中，若数据流控设备为直录播教室，与信息输出直录播教室(也即主课堂)对应的信息输入直录播教室(也即辅课堂)的选取，还可以是以下方式：
信息输出直录播教室(也即主课堂)运行时，接收信息输入直录播教室(也即辅课堂)通过流媒体服务器发送的信息接入请求后，直接向或通过流媒体服务器向信息资源管理平台转发所述信息接入请求
信息资源管理平台对所述信息接入请求按照预设授权审核策略进行授权审核并直接向或者通过流媒体服务器向信息输出直录播教室(也即主课堂)反馈授权审核通过的信息输入直录播教室(也即辅课堂)；
信息输出直录播教室(也即主课堂)通过流媒体服务器向授权审核通过的信息输入直录播教室(也即辅课堂)提供输出的音视频信息。
通过对辅课堂的信息接入请求进行授权审核，实现了灵活的接入控制，大大方便了主课堂的教学管理。
所述预设授权审核策略包括：对信息资源评估因子大于第二预设值的信息输入直录播教室(也即辅课堂)进行授权、对大于预设身份级别的信息输入直录播教室(也即辅课堂)进行授权、若信息输入直录播教室(也即辅课堂)所属区域优先级低于预设区域等级时，则对低于预设区域等级的信息输入直录播教室(也即辅课堂)进行授权。
所述第二预设值、所述预设身份级别、所述预设区域等级可以根据实际情况进行灵活设定，在此不用于限定本发明的保护范围。
信息资源评估因子＝(信息资源引用因子×身份转换因子)/信息资源错误因子。
在实际应用中，若数据流控设备为直录播教室，则
资源引用因子是指直录播教室将信息资源上传信息资源管理平台后被引用次数；身份转换因子是指直录播教室将由辅课堂切换为主课堂的次数；信息资源错误因子是指直录播教室上传的信息资源内容出现错误的次数。
另外，信息输出数据流控设备主动选择一个或多个信息输入数据流控设备并通过流媒体服务器向主动选择的一个或多个信息输入数据流控设备提供输出的信息。
例如：数据流控设备为直录播教室时，若直录播教室1运行后进行信息输出(作为信息输出直录播教室)主动选择直录播教室2、直录播教室3作为信息输入的直录播教室并分别向其提供输出的信息，这大大增强了教学灵活性。
图3所示为本发明实施例3的数据流控设备结构图，包括信息采集处理模块、信息控制模块；其中，所述信息采集处理模块与所述信息控制模块相连；
所述信息采集处理模块，用于获取音视频数据信息并按照第一处理策略处理所述音视频数据信息并向所述信息控制模块发送一次处理后的音视频数据信息；其中，所述第一处理策略包括：图像拼接方式、音视频编码方式、图像去噪处理、图像锐化处理；
所述信息控制模块，用于按照第二处理策略对接收的一次处理后的音视频数据信息进行二次处理后进行对外发送；其中，所述第二处理策略包括：音视频编码方式、数据包封装方式。
图4所示为本发明实施例4的数据流控设备结构图，在图2的基础上，还包括授权审核模块；其中，所述授权审核模块分别与所述信息采集处理模块、所述信息控制模块相连；
所述授权审核模块，用于对接收的信息输入数据流控设备发送的信息接入请求进行授权审核并将授权审核通过的信息输入数据流控设备信息发送至所述信息控制模块；
所述信息控制模块，用于将二次处理后的音视频数据信息发送至授权审核通过的信息输入数据流控设备。
本发明还提供一种终端，包括上述数据流控设备；其中，所述终端包括智能手机、IPad、PC机。
通过以下方案：数据流控系统包括信息资源管理平台、多个数据流控设备、流媒体服务器；其中，所述多个数据流控设备分别与所述信息资源管理平台、所述流媒体服务器相连或所述信息资源管理平台通过所述流媒体服务器分别与所述多个数据流控设备相连；实现了信息资源监控和共享。
通过以下方案：信息输出数据流控设备对信息输入数据流控设备通过所述 流媒体服务器发送的信息接入请求按照预设授权审核策略进行授权审核并通过所述流媒体服务器向授权审核通过的信息输入数据流控设备提供输出的信息；实现了对信息输入数据流控设备的动态接入控制。
通过以下方案：信息输出数据流控设备主动选择一个或多个信息输入数据流控设备并通过所述流媒体服务器向主动选择的所述一个或多个信息输入数据流控设备提供输出的信息，使得选择信息输入数据流控设备的方式更加灵活，个性化教学得到了充分体现。
