- the MCU browser generates the GUI data interface, and the GUI interface can be designed through the HTML page. Not only can various GUI effects be realized, but also the interface can be previewed, and the dynamic page can also be realized through the WEB parser (Webserver). ;
- the AS sends the URL address of the page to be opened to the MCU browser.
- the browser requests the page from the Webserver.
- the Webserver obtains the basic information of the speaker from the service server, generates a web page, and the BW parses the WEB page and performs typesetting through the graphics engine interface.
- the GUI interface is generated, and then the data of the GUI interface of the graphics engine is superimposed by the MCU, and finally the video code stream superimposed with the GUI data is sent to the terminal.
- S507 Send the content of the speech with the current speaker identity information superimposed to the conference terminal; before sending the identity information to each conference terminal, the AS determines whether the user of each participant needs to obtain the identity information of the current speaker, for example, by storing in the AS.
- the identity field is set in the identity information database to mark whether the participant terminal user needs to receive the identity information of the current speaker, and the identity field of a participant terminal user. Set to "Yes” to indicate that the participant terminal user needs to receive the identity information of the current speaker. If the identity field of a participant terminal user is set to "No", the participant terminal user does not need to receive the identity of the current speaker.
- the MCU sends the content of the statement that does not carry the identity information to the participant terminal 121. Sending the content of the speech carrying the identity information to the participant terminal 122.
- the identity information of the person, and the identity information of the current speaker is added to the speech content of the current speaker and sent to the participant terminal of the remote conference, so that the participant knows the identity of the current speaker through the identity information received by the participant terminal, etc.
- the information has deepened the understanding of the contents of the current spokesperson's speech, and solved the problem that the participants in the prior art could not deeply understand the contents of the current speaker's speech due to the inability of the remote conference participants to obtain the current spokesperson's identity information in time.
- Industrial Applicability The conference control method, device, and conference system provided by the embodiments of the present invention obtain the identity information of the current speaker in the identity information database by acquiring the identity information of the current speaker, and send the identity information of the current speaker.

肯定会发生变化, 且大于阈值),或者发言终端采集到的声音信号之间的时间间隔大于 预设值时 (时间间隔是音频特征参数的一种, 其他的音频特征参数可以包括音频的基 音、分普等等)、或者发言终端采集到的视频画面的变化大于预设值时(画面变化是视 频特征参数的一种, 其主要应用于同一终端的发言人发生变化的情况, 其他的特征参 数可以包括视频的亮度值、 色谱等等), 确定当前发言人的步骤; 发言终端采集到的声音信号和视频信号的特征参数与前面相比发生变化时, 主要 如与会终端 12i对采集到的与会人员的声音信号和视频信号进行分析处理, 对相关特 征参数进行提取, 并与前面声音信号的特征参数进行比较, 并对声音和视频信号的各 特征参数进行综合分析, 当这些主要的特征参数发生变化时, 可以认为是发言人发生 了变化,此时主要应用于一个与会终端为二个及以上与会人员服务的情况,具体的如: 在发言的与会终端发生变化时, 主要如发言的与会终端由 121变化为 122, 此时 主要应用于一个与会终端为一个与会人员服务的情况; 发言终端采集到的声音信号之间的间隔大于预设值时, 主要如与会终端 12i对采 集到的与会人员的声音信号之间的时间间隔进行计算, 若一个人自己讲话时, 各语句 之间的停断时间一般为 2秒, 当某一时刻, 语句之间的停断大于 5秒, 可以认为是发 言人发生了变化, 此时主要应用于一个与会终端为二个及以上与会人员服务的情况; 发言终端采集到的视频画面的变化大于预设值时, 主要如与会终端 12i对采集到 的与会人员的人脸画面与背景画面之间的比例进行计算, 若一个人一直发言时, 其人 脸画面与背景画面之间的比例一般稳定, 当发言发生变化时, 在发言人换位 /摄像头调 整这一时刻, 背景画面的比例远远大于人脸画面, 因此, 当人脸画面与背景画面的比 例由稳定变化为突变再到稳定时, 可以认为是发言人发生了变化, 此时主要应用于一 个与会终端为二个及以上与会人员服务的情况。 在确定当前发言人之后, 将从采集到的当前发言人的音频或视音频中直接提取当 前发言人的身份识别信息; 或者通过其他采集设备获取当前发言人的身份识别信息; 进一步的, 身份识别信息包括当前发言人的特征信息和 /或标识信息; 特征信息包括当 前发言人的面部图像、声音信号(包括频率、振幅等标志性特征)、指纹中的至少一种, 标识信息包括当前发言人所使用的与会终端的标识; 具体的可以为: 当身份识别信息为当前发言人的面部图像、 声音信号时, 可以从与会终端采集到 的发言人的视音频码流中直接提取; 当身份识别信息为当前发言人的指纹时, 就需要 通过其他采集设备 (如指纹设备器) 来获取; 当身份识别信息为当前发言人所使用的
与会终端的标识时, 可以直接从其向远处会议控制装置发送的视音频码流中提取, 也 可以通过终端设备装置来获取各与会终端的标识等。
S302: 在远程会议的身份信息库中, 查找与身份识别信息匹配的身份信息; 较优的, 在步骤 S302之前还包括录入与会者身份信息的步骤; 该步骤可以由远程会议的控制者 (主持人) 将所有与会人员 (至少输入所有需要 发言的且与其他与会人员不熟悉的与会人员)的身份信息统一输入到会议控制装置 11 中, 并存储为身份信息库; 该步骤还可以由各与会人员在远程会议开始之前通过为其服务的与会终端输入, 与会终端将接收到的各自服务的与会人员的身份信息发送至会议控制装置 11, 并存储 为身份信息库; 较优的,在步骤 S302之前还包括建立身份信息库的步骤,该步骤的实现可以包括 两种方式: 自动建立及手动输入; 当采用自动建立的方式时, 建立身份信息库的步骤包括在远程会议启动前, 会议 控制装置获取各与会终端使用者的身份识别信息(如面部信息),将该身份识别信息与 该终端绑定的身份信息进行映射对应存储, 生成身份信息库, 该方案适用于一个与会 终端仅服务于一个与会发言者的情况; 当采用手动输入的方式时, 需要该远程与会控制者 /主持人将各与会人员的身份识 别信息与身份信息进行对应存储形成身份信息库之后, 输入到会议控制装置中, 为后 续操作提供基础。 S303 : 将查找到的身份信息发送给至少一个其他与会终端; 较优的, 在给至少一个其他与会终端发送身份信息之前还包括: 确定参与远程会 议的与会终端中需要获取当前发言人的身份信息的所有目的与会终端的步骤; 至少一 个其他与会终端包括所有目的与会终端; 较优的, 确定所有目标与会终端的步骤包括: 判断各与会终端使用者是否需要获 取当前发言人的身份信息, 将需要获取当前发言人的身份信息的与会终端设定为目的 与会终端, 将不需要获取当前发言人的身份信息的与会终端设定为非目的终端; 该步骤的实现可以通过在会议控制装置中设置标识字段来实现, 如使用与会终端 121的与会人员不需要接收发言人的身份信息, 则将其标识字段设置为 "否", 使用与
会终端 122的与会人员需要接收发言人的身份信息, 则将其标识字段设置为"是", 在 执行步骤 S303时, 向与会终端 121发送不携带身份信息的视频画面, 向与会终端 122 发送携带有身份信息的视频画面; 较优的, 当远程会议为视频会议时, 添加身份信息到当前发言人的发言内容中的 步骤包括: 利用 GUI界面将身份信息添加到当前发言人的视频画面中, 并发送给至少 一个其他与会终端。 下面结合具体应用实例对本发明做进一步的诠释说明, 在该应用实例中, 做如下 假设: 远程会议为视频会议, 获取到的身份识别信息为发言人的面部图像, 身份信息 为发言人的职务, 一个与会终端为一个与会人员服务, 现结合图 4及 5进行说明。 图 4为本发明第四实施例提供的远程会议系统的示意图, 由图 4可知, 在本实施 例中,本发明提供的远程会议系统 1包括 AS13、多个 MCU14 ( 141、……、 14i、……、 及 14n)、 多个与会终端 12 ( 121、 ……、 12i、 ……、 R 12η), 图 4中的 AS13、 多个 MCU14相互配合, 实现图 1中会议控制装置 11的功能; 与会终端 12设置为采集其使 用者的视音频, 获得视音频码流, 并传送至与其连接的 MCU, 并接收 MCU发送的视 音频码流, 展示给其使用者。 图 5为本发明第五实施例提供的会议控制方法的示意图, 由图 5可知, 在本实施 例中, 本发明提供的会议控制方法包括以下步骤:
S501 : 输入各与会终端使用者的身份信息; 该步骤可以由视频会议的主持人输入到 MCU中,如与会终端 12i使用者为与会人 员 Ri的职务信息的编号为 Vi。
S502: 获取各与会终端使用者的身份识别信息; 在视频会议初始化时, 各与会终端对其使用者的面部图像进行采集, 并将确定的 身份识别信息发送至 MCU, 如与会终端 12i采集到的其使用者与会人员 Ri的面部图 像的编号为 Li; 与会终端可以通过人脸识别技术来采集并确定其使用者的面部图像, 具体过程并非本发明所关注的重点, 不再赘述。
S503 : 建立身份信息库;
MCU将接收到的职务信息与面部图像根据其所属的与会人员进行对应存储生成 身份信息库, 如在身份信息库中, 编号为 Vi的职务信息与编号为 Li的面部图像对应 存储。
S504: 确定发言终端当前发言人, 获取其身份识别信息; 在视频会议开始, 某一与会终端使用者开始发言时, 或在视频会议进行中发言的 与会终端发送变化时, 执行确定当前发言人的步骤, 将当前讲话的与会终端所对应的 与会人员作为当前发言人; 获取其身份识别信息的方式为直接从发言的与会终端所采 集到的视音频码流中其他发言人的面部图像。
S505 : 在身份信息库中, 查找与当前发言人的身份识别信息对应的身份信息; 如, 步骤 S504在获取到该面部图像之后, MCU根据图像之间的匹配度, 来查找 与会者数据库中存储的与该面部图像匹配度最高的面部图像的编号 Li, 根据与会者数 据库中的面部图像与职务信息的对应关系,将编号为 Vi的职务信息作为查找到的当前 发言人的身份信息。
S506: 将查找到的身份信息添加到当前发言人的发言内容中; 由于本实施例的应用场景是视频会议,可以采用 GUI界面将查找到的身份信息添 加到采集的当前发言人的视频画面中; 具体的可以为 MCU将查找到的身份信息转换 为 GUI数据, 并将 GUI数据叠加到视频码流中, 在一个实施例中, 该方案包括:
MCU浏览器生成 GUI的数据界面, 可以通过 HTML页面来设计 GUI界面, 不但 可以实现各种 GUI效果, 而且界面的所见所得是可以预览的, 另外通过 WEB解析器 (Webserver) 还可以实现动态页面;
AS向 MCU浏览器发送需要打开的页面的 URL地址, 浏览器向 Webserver请求 页面, Webserver从业务服务器那里那里获取发言人的基本信息, 生成 web页面, BW 解析 WEB页面并进行排版,通过图形引擎接口生成 GUI界面,然后将图形引擎的 GUI 界面的数据由 MCU进行视频叠加, 最后将叠加了 GUI数据的视频码流发送给终端。
S507: 向与会终端发送叠加有当前发言人身份信息的发言内容; 在向各会议终端发送身份信息之前, AS判断各与会终端使用者是否需要获取当前 发言人的身份信息, 例如, 通过在 AS存储的身份信息库中设置标识字段来标记各与 会终端使用者是否需要接收当前发言人的身份信息, 某一与会终端使用者的标识字段
设置为 "是"则代表该与会终端使用者需要接收当前发言人的身份信息, 某一与会终 端使用者的标识字段设置为 "否"则代表该与会终端使用者不需要接收当前发言人的 身份信息; 如使用与会终端 121的与会人员的其标识字段设置为"否", 使用与会终端 122的与会人员的标识字段设置为 "是", 则 MCU向与会终端 121发送不携带身份信 息的发言内容, 向与会终端 122发送携带有身份信息的发言内容。 综上可知, 通过本发明的实施, 至少存在以下有益效果: 通过在发言人发生变化时, 确定当前发言人, 获取其身份识别信息, 根据获取到 的身份识别信息在身份信息库中查找当前发言人的身份信息, 并将当前发言人的身份 信息添加到当前发言人的发言内容中一起发送至该远程会议的与会终端, 使得与会人 员通过与会终端接收到的身份信息了解当前发言人的身份等信息, 加深了对当前发言 人发言内容的理解, 解决了现有技术存在的因远程会议与会人员无法及时获取当前发 言人身份信息所导致的与会人员无法深刻理解当前发言人发言内容的问题, 增强了用 户的使用体验。 工业实用性 本发明实施例提供的会议控制方法、 装置及会议系统, 通过获取当前发言人的身 份识别信息, 在身份信息库中查找当前发言人的身份信息, 并将当前发言人的身份信 息发送给至少一个其他与会终端, 使得与会人员通过与会终端接收到的身份信息了解 当前发言人的身份等信息, 加深了对当前发言人发言内容的理解, 解决了现有技术中 当与会人员过多时存在的因与会人员无法及时获取当前发言人身份信息所导致的与会 人员无法深刻理解当前发言人发言内容的问题, 增强了用户的使用体验。 以上仅是本发明的具体实施方式而已, 并非对本发明做任何形式上的限制, 凡是 依据本发明的技术实质对以上实施方式所做的任意简单修改、等同变化、结合或修饰, 均仍属于本发明技术方案的保护范围。
