在本实施例中提供了一种会议系统，图1是根据本公开实施例的会议系统的框架图，如图1所示，该系统包括：第一终端102，第二终端104，切换器106，显示器108以及多媒体 数据输入设备110，其中，所述第一终端102和所述第二终端104互为主备终端；所述多媒体数据输入设备110与所述第一终端102和所述第二终端104连接，设置为将获取的多媒体数据传输至所述第一终端102和所述第二终端104；所述切换器106与所述第一终端102、所述第二终端104以及所述显示器108连接，设置为将所述第一终端102和所述第二终端104中的主用终端传输的所述多媒体数据发送至所述显示器108，以在所述显示器上显示所述多媒体数据,以及，在基于所述第一终端和所述第二终端中的备用终端上报的通知消息确定出所述主用终端发生切换的情况下，将所述备用终端传输的所述多媒体数据发送至所述显示器，以在所述显示器上显示所述多媒体数据，其中，所述通知消息为所述备用终端在检测出所述主用终端发生故障的情况下所触发的。
通过上述系统，由于第一终端和第二终端互为主备终端，且通过使切换器与第一终端、第二终端及显示器连接，此外，可以由备用终端监控主用终端的状态，并在确定出主用终端发生故障时，可通知切换器进行切换并使显示器显示备用终端的多媒体数据，该系统实时性非常高，用户基本感知不到切换，避免了相关技术中需要依赖于独立的监控系统对终端的故障进行监控导致可靠性不够高的问题，因此，可以解决相关技术中存在的因会议系统的可靠性不够高而导致用户使用体验差的问题，达到了提升用户体验的效果。
其中，上述系统可以应用于视频会议系统中，或远程会议系统中，其中，上述第一终端和第二终端可为视频会议系统或远程会议系统中的某个会议室中的互为主备的终端。
在上述实施例中，上述会议系统包括第一终端、第二终端、切换器、显示器以及多媒体数据输入设备，第一终端和第二终端互为主备终端，例如，第一终端为主用终端、第二终端为备用终端，或者，第二终端为主用终端、第一终端为备用终端，在实际应用中，可由备用终端监控主用终端的状态，并在确定出主用终端发生故障时，可切换为由备用终端将多媒体数据输出到显示器上，多媒体数据输入设备与第一终端和第二终端相连，例如，多媒体数据输入设备可以是麦克风、摄像头或其它多媒体输入设备至少之一，这样，多媒体数据输入设备可以将音频、视频或音视频等多媒体数据输入至第一终端和第二终端，而通过使切换器与第一终端、第二终端及显示器连接，可将第一终端和第二终端中的主用终端的多媒体数据传输给显示器，且当第一终端和第二终端中的主用终端发生故障的情况下，还可切换到由第一终端和第二终端中的备用终端传输多媒体数据给显示器，以使显示器能够不间断显示，切换过程对用户透明，用户无感知，实现了提高会议系统的可靠性的目的。
在一个可选的实施例中，所述系统还包括服务器，其中，所述第一终端通过第一连接通道与所述服务器连接；所述第二终端通过第二连接通道与所述服务器连接。在本实施例中，上述会议系统中还包括服务器，例如，局端服务器，且第一终端、第二终端分别通过第一连接通道、第二连接通道与该服务器连接，即第一终端和第二终端通过网络连接服务器，例如，在实际应用中，主备终端均与服务器连接，并且主备终端在连接服务器时所使用的是不同的连接通道，或称为通过不同的网络平面连接网络，其中，主、备会议分别使用两套相对独立的网络连接系统，在一套网络连接系统出现故障后，另一套网络连接系统可以接替参加网络会议。可选地，用户在主用网络连接系统上所执行的任何操作，都会由主备网络连接系统所连接的服务端通知到备用网络连接系统，以使备用网络连接系统做相同操作，从而保持两套系统的一致性。在本实施例中，主、备终端设备上任何时刻都只输出其中一个终端的音视频码流即可。此外，在其他的会议室中，也可以采用类似的多套相对独立的网络连接系统，以 实现多个终端相对独立的连接服务器，在此不再赘述。通过本实施例，可实现有两套独立的网络，分别连接主备两套局端、终端设备，极大地提高了系统的可靠性。
在一个可选的实施例中，所述服务器包括会议电视业务服务控制单元ASC，其中，所述ASC设置为在目标事件的触发下配置所述第一终端和所述第二终端的主备角色，其中，所述目标事件包括以下至少之一：接收到输入的配置指令、确定出所述第一终端和所述第二终端发生主备角色倒换。在本实施例中，服务器中包括会议电视业务服务控制单元ASC，ASC可设置为设置上述会议系统中的第一终端和第二终端的主、备终端角色，ASC可通过多种方式对第一终端和第二终端的主备角色进行配置，例如，在实际应用中，可通过接收用户配置，将第一终端和第二终端中的其中一个终端设置为主用终端及将另外一个终端设备为备用终端，还可通过确定出第一终端和第二终端发生主备角色倒换的情况下对第一终端和第二终端的主备角色进行配置。通过本实施例，实现了通过服务器对第一终端和第二终端的主备终端角色进行灵活配置的目的。
在一个可选的实施例中，所述ASC还设置为在确定出所述第一终端和所述第二终端被配置为特定角色的主备终端的情况下，且在配置所述第一终端和所述第二终端的主备角色之后，通知除当前会议室之外的其他会议室中的终端将各自的和所述当前会议室中的主用终端相对应的终端切换成各自的主用终端，其中，相对应的终端是通过相同的连接通道连接所述服务器的。在本实施例中，当ASC确定出第一终端和第二终端被配置为特定角色的主备终端的情况下，且在配置第一终端和第二终端的主备角色之后，还可根据终端当前角色决定是否通知会议中的其它终端进行切换，例如，在确定出第一终端和第二终端发生主备角色倒换的情况下，切换器切换到根据备用终端的输出进行显示时，即原备用终端变为主用终端时，如果当前主用终端的角色是广播源、主席或发言终端等，则需要通知会议中除当前会议室之外的其他会议室中的终端进行切换，例如，将其他会议室中的与当前会议室中的主用终端通过相同的连接通道连接至服务器的相对应的终端切换成主用终端。通过本实施例，实现了备用系统根据终端在会议中的角色进行全网切换的目的，以保证其他会议室中的终端能够及时接收到会议过程中的消息。
在一个可选的实施例中，所述服务器还包括多点控制信令单元MCU，其中，所述MCU与所述ASC连接，设置为执行以下操作：实时接收备用终端上报的状态信息并将所述状态信息发送给所述ASC，以使所述ASC基于所述状态信息确定出所述第一终端和所述第二终端发生主备角色倒换；接收所述ASC发送的控制指令，以及基于所述控制指令控制所述第一终端和/或所述第二终端。在本实施例中，服务器中还包括多点控制信令单元MCU，MCU实时接收终端的状态信息和ASC的控制指令，把每个终端的状态信息实时上报到ASC，并把ASC控制终端的指令下发给终端，当终端发生故障时，MCU可实时接收终端发生切换的消息并将该消息上报给ASC，MCU还可设置为接收ASC发送的控制指令，以控制第一终端和/或第二终端，即，ASC可以通过MCU执行控制操作，通过本实施例，实现了对终端状态信息进行监测以及在终端发生切换的情况下及时对终端进行控制的目的。
在一个可选的实施例中，所述MCU设置为接收所述ASC在确定所述主用终端被配置为特定对象的情况下所发送的第一控制指令，以及，基于所述第一控制指令将所述备用终端配置为所述特定对象，其中，所述控制指令包括所述第一控制指令。在本实施例中，当ASC确定主用终端被配置为特定对象的情况下，例如，被配置为广播员或主席或发言终端，MCU设置 为接收ASC发送的第一控制指令，以控制备用终端都做工作状态的切换操作，例如将备用终端角色配置为广播员或主席或发言终端。通过本实施例，实现了备用系统根据终端在会议中的角色来采用不同的切换策略的目的。
在一个可选的实施例中，所述MCU还设置为在基于所述第一控制指令将所述备用终端配置为所述特定对象之后，将所述备用终端中的第一设备的状态调整为与所述主用终端中的第二设备一致的状态。在本实施例中，MCU在基于第一控制指令将备用终端配置为上述特定对象之后，如上述将备用终端角色配置为广播员或主席或发言终端之后，MCU还设置为控制调整备用终端中的第一设备的状态，可选地，第一设备可以是喇叭或麦克风，即将备用终端中的喇叭、麦克风状态调整为与原主用终端中的相应设备的状态一致，例如，若原主用终端中的喇叭为静音状态的情况下，则将备用终端中的喇叭也调整为静音状态，例如，若原主用终端中的麦克风为禁言状态的情况下，则将备用终端中的麦克风也调整为禁言状态等等。
在一个可选的实施例中，所述第一终端和所述第二终端连接，其中，所述第一终端和所述第二终端中的备用终端设置为检测所述主用终端的状态，并且确定所述主用终端故障的情况下，通知所述切换器将所述备用终端传输的所述多媒体数据发送至所述显示器，以在所述显示器上显示所述多媒体数据。在本实施例中，备用终端设置为检测主用终端的状态，且在确定主用终端故障的情况下，通知切换器将备用终端传输的多媒体数据发送至显示器以进行显示，在实际应用中，备用终端设备可以实时检测主用终端设备的状态，当发现对方出现故障时，能立即通知切换器进行切换，输出备用设备的音、视频信号。并通知备用系统服务端，由服务端根据业务确定是否要进行全网终端的工作状态切换，如果需要，备用系统服务端将通知会议中所有备用终端，切换为工作终端。原来的工作终端，则置为备用终端。通过本实施例，无需利用单独的监控系统来监控主用终端状态，利用备用终端即可监控主用终端的状态，进而可实现了提高系统监控实时性的目的。
在一个可选的实施例中，所述第一终端和所述第二终端均通过串口连接所述切换器，其中，所述备用终端通过串口通知所述切换器将所述备用终端传输的所述多媒体数据发送至所述显示器，以在所述显示器上显示所述多媒体数据。在本实施例中，备用终端可通过串口通知切换器将备用终端传输的多媒体数据发送至显示器以进行显示。
在一个可选的实施例中，所述系统还包括数字矩阵(或称为数字矩阵设备)，其中，所述多媒体数据输入设备通过所述数字矩阵与所述第一终端和所述第二终端连接，所述数字矩阵用于将所述多媒体数据分为两路，并分别传输至所述第一终端和所述第二终端中。在本实施例中，会议系统还包括数字矩阵，数字矩阵可以将接收到的多媒体数据分为多路，例如，在数字矩阵连接了两个终端的情况下，可以将接收到的多媒体数据分为两路，并分别传输至第一终端和第二终端中，例如，多媒体数据输入设备可以是麦克风、摄像头或其它多媒体输入设备，在实际应用中，数字矩阵能把一路摄像头和麦克风的输出的音视频码流分为两路相同的音视频码流输出到主、备两个终端上。
显然，上述所描述的实施例仅仅是本公开一部分的实施例，而不是全部的实施例。下面结合具体实施例对本公开进行具体说明：
图2是根据本公开具体实施例的会议系统的框架图，如图2所示，该系统包括多个功能单元，各功能单元说明如下：
网络平面202：图2中包括两个网络平面(网络平面1、网络平面2，对应于前述第一连 接通道、第二连接通道)，两套独立网络平面，分别连接主备两套局端、终端设备；
终端204：图2中包括两个终端(对应于前述第一终端、第二终端)，系统中每个会议室分别有主、备两个终端，并且这两个终端通过网络直接连接，能互相检测彼此状态，当发现对方出现异常时，能通过串口通知切换器切换自己的音视频输出到电视设备上，而且终端要向MCU单元上报当前是否为本设备在工作，即主用终端故障切换到备用终端后，备用终端要向MCU单元上报当前是自己为工作终端；
多点控制信令单元206(MCU)：能实时接收终端的状态信息和ASC控制单元208(对应于前述会议电视业务服务控制单元)的控制指令，把每个终端的状态信息实时上报到ASC单元，并把ASC控制终端的指令下发给终端；
ASC处理单元208：为业务控制单元模块，能接收用户配置，设置主、备终端角色。当终端故障时，能通过接收MCU单元上报的某个终端已发生切换消息，并根据当前终端角色，决定是否换终端为主席终端、正在发言终端、广播源终端；
数字矩阵210(即图2中的矩阵)：把同一个摄像头和麦克风(对应于前述多媒体数据输入设备)的视频码率和音频码流输出分为两路分别作为主、备两个终端的输入；
切换器212：同时接受主、备两个终端的输出，并根据终端的控制，选择其中一个终端的音视频码率输出到电视设备214(对应于前述显示器)上展示给用户；
电视机214：通过切换器显示不同终端的音视频输出；
交换机216：设置为信号转发的网络设备，实现多个终端之间的信息信息交换。
各功能单元协作关系说明如下：
1)首先部署两套独立网络系统，连接到ASC业务控制单元、MCU单元；
2)每个会议室部署主、备两个终端(对应于前述第一终端、第二终端)，加入到同一个会中；
3)每个会议室部署一套电视设备(对应于前述显示器)、摄像头、麦克风、切换器、数字矩阵；
4)数字矩阵能把一路摄像头和麦克风的输出的音视频码流分为两路相同的音视频码流输出到主、备两个终端上；
5)切换器能分别接受主、备终端的音视频码流输出，并默认选择主用终端的输出码流传输到电视设备上；
6)主、备终端分别通过串口连接切换器，通过串口命令控制切换器的输出；
需要说明的是，该系统中，总是由备用终端控制切换器进行输出切换；
7)主、备终端之间通过网络建立心跳连接，当备用终端通过该连接检测到主用终端故障时，可以通知切换器切换自己的输出到电视设备；
8)备用终端切换后，通知MCU设备该会议室的工作终端发送了切换；MCU设备把该消息转发到ASC控制单元，ASC根据切换终端当前角色决定是否通知会议中其他终端进行切换；如果当前终端时广播源、主席、发言终端则需要通知会议中其他终端切换，反之则不需要。
在本公开实施例中还提供一种会议系统的终端备份方法，图3是根据本公开实施例的会议系统的终端备份方法流程图，如图3所示，该流程包括如下步骤：
步骤201：用户通过ASC业务控制单元，配置主、备终端，并加入到会议配置中；
步骤202：ASC业务控制单元、MCU多点控制单元配合召集终端开会；
步骤203：会议成功召开后，ASC业务控制单元要记录主用终端的各种角色，如广播源、辅视频源、主席、喇叭、麦克状态；
步骤204：备用系统的终端实时监测主用终端的工作状态；
步骤205：备用终端根据实时监测信息，判断主用终端是否发生故障；
步骤206：如果主用终端发生故障，备用终端通知切换器，把自己的音视频码流切换到电视设备(对应于前述显示器)上，如果无故障，则继续监测；
步骤207：切换器根据备用终端指令，执行把备用终端的音视频码流输出到电视设备的动作；
步骤208：备用终端通知MCU单元，自己已变为工作终端；
步骤209：MCU通知ASC业务控制单元，有一个会议室的工作终端发生了切换；
步骤210：ASC业务控制单元，检查当前发生切换的终端的角色；
步骤211：ASC业务控制单元判断发生切换的终端角色是否是广播员、辅视频源、主席；
步骤212：如果当前发生切换的终端是广播员或主席或发言终端，ASC控制单元要通知MCU单元控制备用终端都做工作状态的切换操作、并把备用终端角色设置为广播员、辅视频源、主席；
步骤213：ASC业务单元通知MCU单元控制备用终端的喇叭、麦克状态和原主要终端一致；
步骤214：备用终端把自己的状态设置为主用工作终端状态；
步骤215：ASC业务控制单元通知之前的主用工作终端，状态切换为备用终端；
终端备份结束。
在上述实施例中，检测主用终端故障的方式，是由备用终端来进行的；主用系统服务端要把所有操作同步给备用系统服务端；备用系统根据终端在会议中的角色来采用不同的切换策略，通过上述实施例，根据视频会议的场景，主、备系统之间实时同步了终端在会议中的角色(包括广播源、辅视频源、主席，在视频会议中这些角色终端图像和声音码流是要推送给所有终端的)；备用终端主动探测主用终端状态，当备用终端转为主用终端时，主动通知备用系统服务端，服务端根据备用终端的角色来确定其他终端的切换策略。通过这种方式，实现了当备用终端是广播源、辅视频源、主席等角色时，系统的全网切换，且对用户基本无感知。本公开实施例可应用于政府、运营商等对会议质量、稳定性要求严格的高规格视频会议中。
以上所述仅为本公开的优选实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开可以有各种更改和变化。凡在本公开的原则之内，所作的任何修改、等同替换、 改进等，均应包含在本公开的保护范围之内。
