Description
一种基于图像的视讯会议控制方法、 终端及*** 本申请要求于 2009 年 4 月 8 日提交中国专利局、 申请号为 200910038505.6, 发明名称为"一种基于图像的视讯会议控制方法、 终端及系 统"的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及网络通信技术领域, 尤其涉及一种基于图像的视讯会议控制 方法、 终端及***。
背景技术
目前视讯会议终端作为专业类视讯终端, 一直不能像消费类视讯终端般 那样提供友善、 便捷、 直观的人机交互界面。 修改会议配置或进行会议控制, 都需要逐级进入特定的菜单界面进行操作,不论是 WEB方式,还是鼠标方式, 都不可避免让用户花大量时间了解掌握复杂的交互界面的菜单意思。
同时, 各种各样的菜单操作界面, 包括透明界面、 隐藏界面、 界面小型 化、 各种快捷键、 界面单独输出, 无论设计好坏, 都在和会场图像争夺有限 的显示窗口, 占据显示屏较大显示面积。 这种在会议中必须频繁使用的菜单 操作界面, 也分散了人们的注意力, 可能会漏掉某个会议中需要关注的地方。 即使派专职人员维护会议控制, 也不能很好的解决上述存在的问题和不足。
目前视讯会议的控制方法主要包括两种: 方法一、 导演控制方法, 即从 ***中央控制操作台上进行广播会场、 观看会场、 声控切换、 多画面设置、 结束视讯会议等操作。 方法二、 ***终端控制方法, 即设置***终端, 从主 席终端上进行广播会场、 观看会场、 声控切换、 多画面设置、 结束视讯会议 等操作。
其中所述方法一, 通过***中央控制操作台上进行视讯会议控制, 由于 视讯会议用户感觉不到操作台的存在, 由参加视讯会议人员直接从操作台上 进行会议控制是不现实的。 必须配备操作人员在后台进行视讯会议控制, 且
视讯会议控制命令需由视讯会议主持人下发给操作人员, 再由操作人员根据 控制命令进行视讯^ i义控制。
所述方法二, 通过***终端实现视讯会议控制。 由参加会议的会议终端 申请成为***终端, 申请成功后, 通过在会议终端界面上的操作来完成控制 会议。 但通过***终端实现视讯会议控制时, 需要逐级进入特定的菜单界面 进行操作其控制操作很烦瑣, 为实现一个视讯会议控制操作如结束视讯会议 等往往需要进行多项选择、 进入多级菜单才能够找到相关的视讯会议控制操 作, 使用起来非常不方便; 而且控制菜单界面和会场图像争夺有限的显示窗 口, 会分散 义参加人员的注意力。
本发明人在实现本发明的过程中发现: 上述方法一必须配备操作人员在 后台进行视讯会议控制, 且视讯会议控制命令需由视讯会议主持人下发给操 作人员, 再由操作人员根据控制命令进行视讯会议控制, 不能根据会议要求 及时控制各个会场情况。 上述方法二需要逐级进入特定的菜单界面进行选择 操作, 其控制操作非常不方便, 而且控制菜单界面会占据显示屏上各个会场 图像显示窗口, 影响会议观看效果。

具体实施方式
为使本发明更加容易理解, 下面结合附图对本发明作进一步阐述, 但附 图中的实施例不构成对本发明的任何限制。
本发明实施例提供了一种基于图像的视讯 义控制方法及***, 支持在 远端和本端的会议终端上通过直接操作会场画面进行所有基本会场控制, 在 所有组合画面模式(包括单画面) 下控制是一样的, 会场控制操作的对象是
所有子画面所对应的会场音频源码流和视频源码流。
实施例一
如图 1所示,本发明实施例一提供了一种基于图像的视讯^ i义控制方法, 包括步骤:
101、 向网络侧发送控制请求消息。
通过会汉终端向网络侧的多点^ i义控制装置,即多点^ i义控制单元 MCU 发送控制请求消息, 所述控制请求消息包括维护设置本地会议终端的请求和 / 或远程视讯会议的控制请求。 具体的, 在没加入会议情况下, 通过会议终端 向网络侧的多点会议控制装置发送维护设置本地会议终端的请求; 在加入会 议情况下, 根据会议需要, 通过会议终端向网络侧的多点会议控制装置发送 各种远程视讯会议的控制请求。
102、 根据网络侧反馈的控制消息, 动态显示图像信息。
会议终端根据网络侧的多点会议控制装置反馈的控制消息, 动态显示本 地^ i义终端视频源图像信息, 或各个 义终端对应的会场视频源图像信息。
103、 据所述图像信息, 对图像进行编辑, 完成视讯^ i义控制。
在没加入^ i义情况下, 通过^ i义终端, 当控制人员根据显示的所述本地 会议终端视频源的地址本信息, 选择会场浏览模式时, 可以进行浏览、 新增、 修改、 删除地址本内容和召集会议的操作; 或者当控制人员根据显示的所述 本地会议终端视频源配置图像信息, 选择非会场浏览模式时, 可以在所述本 地会议终端相应子画面位置分别设置主流或辅流视频源。
在加入到^ i义情况下, 通过^ i义终端, 当控制人员根据显示的所述各个 会议终端对应的会场视频源图像信息, 选择会场浏览模式时, 通过对所述各 个对应的会场视频源图像的点击编辑, 完成视讯会议控制操作; 或者当控制
浏览模式时, 选择切换^ i义中的主流或辅流视频源图像。
视频源显示所述会议终端对应的会场人员插播的静态画面或动态画面, 其中 所述静态画面包括演示的电子文档或电子图片, 所述动态画面包括播放的视 频文件或外接摄像头的输入图像。
本发明实施例提供的方法支持在所有组合画面模式下进行会场控制操 作, 各个会场的人员可以在会议终端上选择浏览模式, 其中浏览模式包括会 场浏览模式和非会场浏览模式。 所述会场浏览模式和非会场浏览模式的主要 区别为, 在会场浏览模式下, ***自动显示所有会场的情况, 可以浏览并控 制会议中的所有会场对应的视频源图像; 而在非会场浏览模式下, ***不能 自动显示所有会场的情况, 会场控制对象和会场控制对象的数目, 受限于具 体的组合画面模式, 例如在单画面情况下, 只能针对一个视频源进行会场控 制操作。
会场浏览模式也是一种虚拟场景模式, 会场浏览模式支持的组合画面形 式有单画面、 二画面、 四画面、 九画面和十六画面。 点对点呼叫情况下默认 四画面, 多点呼叫情况下默认十六画面。 根据多点会议控制单元反馈的控制 信息, 会议终端动态显示各个会场图像信息组成的会议列表。
为实现本发明的方法, 参加^ i义人员根据显示的 义列表中相关会场子 画面图像信息, 可在会议终端上直接按键操作, 或通过相关遥控器功能按键 完成对应的会场控制操作。 例如可控制进行观看会场、 声控切换、 多画面设 置、 切换、 请求发言、 结束视讯会议等操作, 具体操作在下面的实施例中描 述。
如图 2所示, 当在会场浏览模式下动态浏览^ i义列表的流程如下: 1、会议终端申请加入远程视讯会议后, 比如在遥控器上按 DIRECTORY 键(该按键可复用其他遥控器按键或新定义)使会议终端直接进入会场浏览 模式, 并向多点会议控制装置请求浏览所有会场, 作为一种实施方式, 该多 点会议控制装置可以是远程会议***的多点会议控制服务器。
2、 多点会议控制服务器根据会场列表信息, 依次将来自各个会场的视
频源的码流数据发送给所述请求进行会场浏览的会议终端, 多点会议控制服 务器控制循环的发送相应会场的码流数据, 循环更新各个会场的图像。
3、 所述会议终端收到控制信令和相应会场的码流数据后, 依次在显示 屏对应的子画面位置显示出来, 保存并维持上一码流截屏, 维护会场索引信 息。 维持的各个码流的静止图像, 可用于下一次会场浏览, 也可用于地址本、 群组本、 呼叫记录、 日志等, 作为辅助信息一并记录。 远端会场视频源多画 面一般是一路码流, 会议终端需要自己区分识别出不同会场视频源在多画面 中的位置。 一方面多点会议控制服务器在设置多画面时, 将各个会议终端在 多画面中的对应子画面位置信息通过信令发送给各个会议终端; 另一方面各 个会议终端在申请加入远程视讯会议时, 通过向多点会议控制服务器询问各 个^ i义终端在自己屏幕多画面中的对应子画面位置信息。 若会场视频源过多, 在当前会场浏览模式下无空白子画面位置显示时, 则不显示相应会场的视频, 但依然正常解码, 等待有无其它会场退出会议释放会议资源后再显示。
如图 3所示, 义建立之后, 会场人员可通过遥控器上下左右的方向键 查看会场列表, 即移动闪烁的会场子画面框查看会场列表, 对于会议中的未 入会会场和纯音频会场, 使用默认图片替代显示。
会议***终端可以观看整个会场列表, 根据各个会议终端显示的图像信 息, 通过遥控器功能按键操作完成视讯会议中相关会场的控制。 如图 4所示, 当有新的会议终端需要加入会议时, 具体控制步骤如下:
( 1 ) 需要加入会议的新会议终端通过遥控器按键向多点会议控制服务 器发送入会申请信号;
( 2 ) 多点会议控制服务器将该入会申请信号转发给会议***终端, 在 显示屏的会场状态栏中显示新会议终端的相关信息, 包括会场名称、 号码、 线路类型、 速率、 IP地址等;
( 3 )会议***终端进入会场浏览模式, 观看所有会场列表, 通过遥控 器方向键上下左右选择选择一个空白子画面位置, 添加新会议终端的相关信
息, 包括叠加字幕标识会场名、 选择视频源等操作, 最后在该确定的空白子 画面位置显示新会议终端的视频。
如图 5所示, 如果会议中的会场数目较多, 比如有十八个会场, 一屏显 示不完, 则可以通过上、 下键回卷显示, 或者 PAGE UP、 PAGE DOWN键翻 页显示, 进行相关的视音频源的选择切换操作。
下面再具体以操作方式说明在该会议终端***中基于图像进行会议控 制过程。 本发明实施例结合会议终端用户使用遥控器来说明具体操作过程, 本发明实施例所需要的遥控器按键功能不做具体定义和限定, 可以理解的是 会议终端用户也可以采用其他控制方式来控制视讯会议。
一、 设置本地输入视频源步骤如下:
( 1 )没开会情况下, 选择非会场浏览模式, 设置定义子画面位置 1 显 示本地主流视频源, 定义子画面位置 2显示本地辅流视频源;
( 2 )选择子画面位置 1或者子画面位置 2, 双击图像框激活, 进行选择 视频源匹配添加到对应子画面的操作。 这时子画面位置 1 显示的图像视频源 即为当前设置的本地主流视频源; 子画面位置 2显示的图像视频源即为当前 设置的本地辅流视频源。
二、 如图 6所示, 在非会场浏览模式下, 选择画面显示视频源的控制步 骤如下:
( 1 )在非会场浏览模式下, 选择一个或多个画面双击;
( 2 )按遥控器的 DISPLAY键切换该画面显示的视频源;
( 3 )所有视频源按照默认顺序依次切换, 按键一次, 切换一次; ( 4 )在没开会情况下, 通过所述会议终端在相应子画面位置选择切换 本地主流或辅流视频源, 例如选择切换本地会场视音频信号、 本地会场输入 的摄像头信号、 本地会场外接电脑输入的演示电子文档; 在开会情况下, 根 据会议需要,通过所述会议终端选择切换会议中的主流或辅流视频源,比如 A 会场人员发言时, ***将录制 A会场情况的的主流视频源广播给会议中每个
会议终端,如果 A会场人员需要演示一个外接电脑的 WORD文档, 就可以切 换成辅流视频源显示 WORD文档。
三、 如图 7所示, 在会场浏览模式下, 选择画面显示视频源的控制步骤 如下:
( 1 )在会场浏览模式下, 选择一个开始浏览的子画面双击;
( 2 )按遥控器的 DISPLAY键切换各个画面显示的视频源;
( 3 )所有视频源按照默认顺序从所述开始浏览的子画面依次切换显示, 显示效果类似 VCD/DVD的九画面预览效果, 如图 7所示, 比如点对点呼叫 时, 选择会场浏览模式, 则进入四画面, 依次显示本地主流、 本地辅流、 远 端主流、 远端辅流。 整个会议显示大屏幕中, 多点会议中共有 9个视频源, MCU当前正在发送更新码流 7的图像, 码流 1、 2、 3、 4、 5、 6、 8、 9子画 面位置维持显示上一次更新后的静止图像, 下一个将要更新的码流是码流 8。
四、 设置本地及会场观看视频源步骤如下:
( 1 )在会场浏览模式下, 多点会议中, 选择一个或先后选择两个画面 按键 SOURCE键双击激活;
( 2 )若只有一个画面被激活, 规定设置本地会场观看视频源, 设置的 观看视频源为被选择画面的显示视频源;
如图 8所示, 比如在当前本地会场观看画面 (如选择四画面), 设置本 地会场的观看视频源。 进入会场列表选择预观看的会场图像, 可以是一个或 更多, 如果选择 4个会场, 按键 SOURCE键后, 会场列表中被选中的会场, 会以多画面的组合形式显示在本地会场中, 即在本地会场视频源 1 的观看画 面中显示会场 4、 7、 13、 16的图像;
( 3 )若有两个画面被激活, 规定第一个画面所对应会场的观看视频源 为第二个画面所对应会场的视频源。 (仅针对拥有对会场码流设置权限的会 场)
如图 9所示, 会场一〜四对应视频源 1~4。 以本端显示四画面为例, 使能
会场一、 会场三, 会场一所观看的会场(其他会场)被切换为会场三的画面; 如果被观看会场 (如会场三) 同时发送辅流, 会场一观看的远端辅流画面切 换显示会场三的辅流。
五、 对会议中发言的控制过程。
比如如果有另外的会场想发言, 则通过遥控器上 "申请发言" 键向多点 会议控制服务器发送申请信号, 所述多点会议控制服务器则控制在各个会议 终端显示屏上闪烁需要发言的会场对应的子画面视屏图像, 提示哪个会场需 要发言, 请发言完毕的会议终端结束发言后释放会议资源给申请发言的会议 终端。
下面再具体说明对子画面的各种操作方式。
一、 高亮框显示当前用户所选的子画面。
如图 10所示, 用户选择的组合画面中的当前子画面会有高亮框, 即闪 烁框提示用户, 当用户在某时间段内没有对当前子画面进行视频源切换操作, 高亮框将自动消失。 在图 10中, 组合画面左上角的子画面会场一表示当前选 中的子画面, 用户可以对该子画面进行操作。
二、 擦除画面的操作如图 11所示
( 1 )在非会场浏览模式下, 选择一个或多个画面点击激活该画面;
( 2 )按键 BACKSPACE键擦除画面, 被选择的子画面位置就无显示图 像.
三、 自动填充画面的操作如图 12所示
( 1 )在非会场浏览模式下, 选择一个或多个空白画面双击激活;
( 2 )按键 DISPLAY键, 使用当前视频源填充显示所有被选择的空白画 面。
四、 缩 /放画面的操作如图 13所示
( 1 )在会场浏览模式或非会场浏览模式下, 选择一个或多个画面双击 激活;
( 2 )按键 ZOOM IN/ZOOM OUT键后, 被选择的画面被缩 /放;
(3)若选择画面对应本地会场视频源, 则进行本地摄像机控制或者本 地编解码缩 /放;
(4)若选择画面对应远端会场视频源, 则请求远端摄像机控制; 五、 观看 /取消全屏的操作如图 14所示
(1)在会场浏览模式或非会场浏览模式下, 选择一个画面双击激活;
(2)按键 RESIZE键, 若画面焦点为多画面中的子画面, 则该子画面被 切换到单画面模式下显示; 若画面焦点为单画面, 则画面被切换到原多画面 模式下显示; 若原多画面模式不存在, 则不处理;
六、 选择成为主子画面
(1)在非会场浏览模式下, 选择一个画面双击激活;
(2)按键 SWAP键后, ***判断出只有一个画面双击激活, 自动将被 选择画面视频源与当前主子画面视频对换, 成为新的主子画面;
七、 交换画面显示位置的操作如图 15所示
(1)在会场浏览模式或非会场浏览模式下, 选择两个画面双击激活;
(2)按键 SWAP键, 交换两个画面位置的显示视频源.
下面再具体说明 义控制操作的过程
1、 设置本地多画面显示, 如图 16所示
