为了更详细的说明本申请实施例提供的会议设备320的应用场景，下面结合3个实例对本申请实施例提供的会议设备320进行举例说明。
实例1
可选的，该会议设备320还包括音响326和存储模块327，音响326和数据处理模块329 连接，存储模块327用于存储第一多媒体数据或第二多媒体数据，以便用户后续复查。数据处理模块329包括视频处理模块3292(video sub-system)、音频处理模块3291(audio)和USB模块3293(USB device/host)，数据采集模块328包括摄像头3282和麦克风3281，摄像头3282通过移动产业处理器接口(mobile industry processor interface，MIPI)线与视频处理模块3292连接，USB模块3293也通过MIPI线与视频处理模块3292连接，麦克风3281通过集成电路内置音频总线(Inter-IC Sound，I2S)和音频处理模块3291连接，音频处理模块3291通过I2S总线和音响326连接。
具体的，请一并参考图4和图5，数据处理模块329为中央处理器(central processing unit，CPU)，音响326用于播放第一多媒体数据或第二多媒体数据中的音频数据。音频处理模块3291包括音频输入模块401(audio in，AI)、音频输出模块404(audio output，AO)、前处理模块402和后处理模块403，音频数据通过音频输入模块401输入后，可以直接通过音频输出模块404输出，也可以输入至前处理模块402和后处理模块403进行混音和后处理等操作，然后通过音频输出模块404输出。视频处理模块3292包括视频输入模块501(video in，VI)、视频输出模块506(video output，VO)、图像信号处理模块502(image signal processing，ISP)、视频处理子系统模块503(video process sub-system，VPSS)、编码器504(encoder)和全景拼接模块505(any view stitching，AVS)，其中第一多媒体数据或第二多媒体数据中的视频数据通过视频输入模块501输入，视频输入模块501还可以对视频数据中的图像进行降噪处理，并输出多路不同分辨率的视频数据，图像信号处理模块502用于对输入的视频数据进行信号处理，可以匹配不同厂商的图像传感器。视频处理子系统模块503可以对视频数据中的图像进行增强和锐化等处理，并实现同源输出多路不同分辨率的视频数据，用于编码、预览或抓拍等，编码器504可以对视频数据进行编码，全景拼接模块505可以对视频数据中的图像进行多画面的拼接，视频输出模块506可以进行播放控制等处理，并按照用户配置的输出协议输出给外部，视频数据通过视频输入模块501输入后，可以通过视频输出模块506直接输出，也可以经过上述任意模块处理后，通过视频输出模块506输出。摄像头3282用于采集第二多媒体数据中的视频数据，麦克风3281用于采集第二多媒体数据中的音频数据。USB Type-C线和第一通信接口321还支持第三信号格式，第三信号格式为USB视频类(USB video class，UVC)信号格式和USB音频类(USB audio class，UAC)信号格式，USB模块3293用于给计算机设备310提供分配器(device)的功能。USB Type-C线采用USB3.0协议或USB3.1协议。
示例性的，数据采集模块328采集到第二多媒体数据后，将第二多媒体数据通过USB设备和第一通信接口321发送给计算机设备310，其中第二多媒体数据的信号格式为UAC和/或UVC，这样计算机设备310就使用到了会议设备320的功能。计算机设备310收到第二多媒体数据后，将第二多媒体数据作为会议软件的输入，供其他与会方观看。
计算机设备310通过网络或其他方式获取到其他与会方的多媒体数据。在这种场景下，计算机设备310可以展示其他与会方的多媒体数据，或者，除了展示其他与会方的多媒体数据之外，还展示上述的第二多媒体数据。
可以理解，计算机设备310自身也可以生成多媒体数据，例如计算机设备310的桌面数据，或计算机设备310自带的摄像头采集的多媒体数据。为便于描述，本实施例中，将其他与会方的多媒体数据，或者，其他与会方的多媒体数据和计算机设备310生成的多媒体数据称为第三多媒体数据。
通过前面描述可知，计算机设备310可以获取第二多媒体数据和第三多媒体数据。计算 机设备310将第二多媒体数据和第三多媒体数据进行转换和编码，得到第一多媒体数据，此时第一多媒体数据中包括第二多媒体数据、其他与会方的多媒体数据和/或计算机设备310自身产生的多媒体数据。计算机设备310将第一多媒体数据发送给会议设备320，信号转换模块323接收到第一多媒体数据信号转换模块323将DP信号格式的第一多媒体数据转换为HDMI信号格式后，将HDMI信号格式的第一多媒体数据发送给投屏设备330展示，示例性的，此时投屏设备330展示了计算机设备310的桌面，桌面中包括会议软件，会议软件中包括其他与会方的多媒体数据和第二多媒体数据。
示例性的，数据采集模块328采集到第二多媒体数据后，可以不将第二多媒体数据发送给计算机设备310，而直接将第二多媒体数据发送给投屏设备330进行展示，用户可以基于此进行会议设备的测试。
可选的，如图6所示，计算机设备310自带计算机摄像头312和计算机麦克风311，此时计算机设备310可以采集自身所在的会议现场的多媒体数据。计算机设备310可以将采集到的多媒体数据通过会议设备320发送给投屏设备330进行投屏。具体实现中，该多媒体数据作为DP信号通过USB Type-C线发送给会议设备320的第一通信接口321，经过管脚转换模块325后，会议设备320的信号转换模块323将该多媒体数据的第一信号格式转换为第二信号格式，得到HDMI信号的多媒体数据，输出切换模块325将HDMI信号的多媒体数据通过第二通信接口322发送给投屏设备330进行展示，即展示计算机设备310采集到的会议现场的多媒体数据。
或者，计算机设备310将计算机摄像头312和计算机麦克风311采集到的多媒体数据和会议设备320采集到的第二多媒体数据处理得到第一多媒体数据，并将第一多媒体数据通过会议设备320发送给投屏设备330进行展示。示例性的，计算机摄像头312和数据采集模块328的摄像头3282分别采集会议现场内不同角度的视频，计算机麦克风311和数据采集模块328的麦克风3281分别采集会议现场内不同位置的音频，计算机设备310将计算机摄像头312采集的视频和第二多媒体数据中摄像头3282采集的视频进行拼接，得到第一多媒体数据中的视频数据，计算机设备310还将计算机麦克风311采集的音频和第二多媒体数据中麦克风3281采集的音频分别作为不同声道进行融合，得到第一多媒体数据中的音频数据，此时投屏设备330展示的第一多媒体数据包括了更完整的会议现场视频和多声道的会议现场的音频，提升了用户体验。
需要说明的是，由于计算设备310或者会议设备320可能使能的只有麦克风，或者只有摄像头，又或者同时使能了麦克风和摄像头，第一多媒体数据和第二多媒体数据中可以只为音频数据，也可以只为视频数据，还可以包括音频数据和视频数据。
实例2
在实例1的基础上，可知计算机设备310和会议设备320在USB Type-C线的传输中可能存在同时传输DP信号格式的数据和UAC和/或UVC信号格式的数据，UAC和/或UVC信号格式的数据支持USB Type-C线的正反插，但DP信号格式的数据不支持，因此管脚转换模块324用于在USB Type-C线反插时将USB Type-C线的管脚的输入进行转换。
具体的，如图7A和图7B所示，对于作为母头来说的第一通信接口321中，UAC和/或UVC信号格式走TX1+、TX1-、RX1+和RX1-的管脚，DP信号格式走DP0+、DP0-、DP1+和DP1-的管脚，即TX2+、TX2-、RX2+和RX2-的管脚，管脚转换模块324(sw)可以实现数据选择器(multiplexer，MUX)功能，实现管脚的复用和交换，在USB Type-C线反插时将USB Type-C线的管脚的输入进行交换。
实例3
在实例1的基础上，由于会议设备320的音响326和麦克风3281都位于会议会场内，当计算机设备310通过网络或其他方式获取到其他与会方的多媒体数据后，将其作为第三多媒体数据与接收到的会议设备320中的数据采集模块328采集的会议现场的第二多媒体数据一起进行转换，得到第一多媒体数据。并将所述第一多媒体数据发送给会议设备320的音响326播放。此时，数据收集模块328的麦克风3281会重新采集到第一多媒体数据的音频数据。此时的第二多媒体数据经过转换后被重复播放后会产生回声问题。
当数据处理模块329中的音频处理模块3291接收数据采集模块328发送的第二多媒体数据后，音频处理模块3291利用从第一通信接口321接收的计算机设备310发送的第一媒体数据对所述第二多媒体数据进行回声抵消。具体可以是将其中的音频数据作为参考音，把第二多媒体数据中麦克风3281重新采集到第一多媒体数据中重复的音频数据抵消掉，完成回声消除处理，避免了回声问题。
其中，第一多媒体数据可以作为UAC信号格式通过第一通信接口321、USB模块3293发送给音频处理模块3291，也可以作为DP信号格式通过第一通信接口321、管脚转换模块324发送给音频处理模块3291，音频处理模块3291可以将这两种信号格式的第一多媒体数据都作为参考音，提升回声处理效果。在进行回声消除处理时，音频处理模块3291具体使第二多媒体数据中的音频数据与参考音的时钟尽可能同步对齐，并保证及其他如波束和声源定位时音频数据的相位一致，在软件上采用时钟同源算法，同时结合AI残留回声处理，提升回声抵消效果。
还需要说明的是，若存在其他场景中不存在回声问题，例如麦克风3281不采集音频数据，则不进行回声消除处理，即不需要将第一多媒体数据发送给数据处理模块329中的音频处理模块3291。
实例4
在实例1的基础上，计算机设备310默认不开启会议软件功能，会议设备320和投屏设备330默认连接，当第一通信接口321与计算机设备310断开时，即计算机设备310没有通过USB线和会议设备320的第一通信接口321连接，或者计算机设备310没有开启会议软件功能时，输出切换模块325控制第二通信接口322输出第二多媒体数据，即投屏设备330上展示会议设备320采集的第二多媒体数据，其中输出切换模块325相当于一个切换开关，此时输出切换模块325使投屏设备330与数据处理模块329导通，与信号转换模块323断开。
当第一通信接口321与计算机设备310连接时，或第一通信接口321与计算机设备310连接且计算机设备310开启会议软件功能时，输出切换模块325控制第二通信接口322输出第一多媒体数据，此时输出切换模块325使投屏设备330与数据处理模块329断开，与信号转换模块323导通。
总结上述各个实施例可见，本申请实施例带来的有益效果包括而不限于下述(1)至(4)。
(1)降低了会议部署的连线复杂程度。

(3)对音频数据进行回声消除。
