Abstract: A system for recording a video session includes a video server and a client coupled to the video server using a communication path. The video server communicates a start record command. The client determines the processing capacity of the client and establishes a recording interval in response to the determined processing capacity. The recording interval indicates a time between a first recording time and a second recording time. The client records a first video frame at the first recording time in response to the start record command, and records a second video frame at the second recording time. The first video frame includes first video data and the second video frame includes second video data. The client generates a video sub-frame comprising the second video data that is different from the first video data.

Abstract translation: 用于记录视频会话的系统包括使用通信路径耦合到视频服务器的视频服务器和客户机。 视频服务器通信启动记录命令。 客户端确定客户端的处理能力并响应于确定的处理能力建立记录间隔。 记录间隔表示第一记录时间和第二记录时间之间的时间。 客户端响应于开始记录命令在第一记录时间记录第一视频帧，并在第二记录时间记录第二视频帧。 第一视频帧包括第一视频数据，第二视频帧包括第二视频数据。 客户端生成包括与第一视频数据不同的第二视频数据的视频子帧。
