    • 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。
