摘要： A system and method for creating a virtual round table videoconference is described. An embodiment of the system comprises a plurality of displays arranged in an configuration with a table to create a virtual round table. Cameras are arranged around the plurality of displays such that when a participant looks at a display with a image of a remote participant, the camera associated with the display captures an image of the participant's gaze, making eye contact with the camera. The image is displayed at the remote participant's endpoint creating the effect of eye contact between the participants. Images of participants are scaled such that those displayed at the left and right sides appear visually closer than those displayed in the center. In another embodiment, audio speakers are arranged to provide directional sound that the video source for a display and the audio source for the associated speaker are from the same endpoint.

摘要： A system and method for reducing blurred video caused by intra-coded IDR- frames sent in response to when a destination endpoint in a multipoint videoconference switches to a new video source. An embodiment according to the invention comprises using inter-coded temporal predictive referencing a long term reference frame (LTRF) instead of EDR-frames in a multipoint videoconference system.

摘要： Techniques are provided for managing long-term reference frames (LTRFs) for two or more video sources. A first video source is selected from a plurality of video sources. The first video source is encoded to produce an encoded video stream, where a reference frame message identifies a recent video frame as long-term reference frame (LTRF) associated with the first video stream. The process is repeated for other video streams. The LTRF associated with the first video stream is used as a reference for temporal predictive coding upon receiving a signal that the first video source has been re-selected.
摘要翻译：提供了用于管理两个或多个视频源的长期参考帧（LTRF）的技术。从多个视频源中选择第一视频源。第一视频源被编码以产生编码视频流，其中参考帧消息将最近的视频帧标识为与第一视频流相关联的长期参考帧（LTRF）。对其他视频流重复该过程。与第一视频流相关联的LTRF在接收到已经重新选择第一视频源的信号时用作时间预测编码的参考。
