    • Embodiments of the invention provide a screen sharing technology including a local computing device and a remote computing device. The local computing device compresses pixel data captured from a frame buffer of the local computing device into a video stream. When the local computing device determines that a video visual component is to be displayed, it obtains compressed data for the video visual component, location information and temporal information. The remote computing device decodes the compressed data and the video stream in different decoder and displays the video stream and compressed data on its monitor according to the temporal information and location information. As such, the embodiment described above leads to better coding efficiency, better coding quality, and lower bit rate.
    • 本发明的实施例提供一种包括本地计算设备和远程计算设备的屏幕共享技术。 本地计算设备将从本地计算设备的帧缓冲器捕获的像素数据压缩成视频流。 当本地计算设备确定要显示视频可视组件时,它获得用于视频可视组件,位置信息和时间信息的压缩数据。 远程计算设备对不同解码器中的压缩数据和视频流进行解码,并根据时间信息和位置信息在监视器上显示视频流和压缩数据。 因此,上述实施例导致更好的编码效率,更好的编码质量和较低的比特率。

    • A framework for a screen content sharing system with generalized screen descriptions is described. In one approach, a screen content update message is sent from a client device to a control plane where the client device wishes to share its screen content with a remote device. The remote device sends a message indicating an interest in receiving said update. The control plane subsequently retrieves a detailed description from the client device. Based on the computational context of the remote device, the detailed description may be trimmed to a more compatible format. In some embodiments, the detailed description is sent to the remote device and includes a screen description and a content description. The content of the shared screen is described and the content is subsequently retrieved from a service router. A shared screen content is assembled based on the screen description and the content retrieved from the service router.
    • 描述了具有广义屏幕描述的屏幕内容共享系统的框架。 在一种方法中,屏幕内容更新消息从客户端设备发送到控制平面,在该控制平面上,客户端设备希望与远程设备共享其屏幕内容。 远程设备发送指示接收所述更新的兴趣的消息。 控制平面随后从客户端设备检索详细描述。 基于远程设备的计算上下文,可以将详细描述修剪成更兼容的格式。 在一些实施例中,详细描述被发送到远程设备,并且包括屏幕描述和内容描述。 描述共享屏幕的内容,随后从服务路由器检索内容。 基于屏幕描述和从服务路由器检索的内容来组合共享屏幕内容。
