ABSTRACT

    Presented herein is a technique to retain a previous active speaker while a new active speaker is speaking. Both the previous and current active speakers can be displayed simultaneously side-by-side, with deliberately designed proportions. The proportions of the previous and current active speakers are dynamically adjusted over time.

DETAILED DESCRIPTION

     In normal online video conference, when active speaker changes from attendee A to attendee B, the video content changes from A's video stream to B's video stream. There is a drawback in that the other attendees have no idea who was the previous speaker if he/she has just joined the online conference for a period of time, for example, 10 seconds.

    A similar drawback occurs in the following scenario. Often, two or more attendees in an online video conference have a debate during which the active speaker may rapidly change from one to another as shown in Figure 1 below. The video content switches from one attendee's video stream to the video stream of another rapidly as well. However, there is no visual context. For example, attendee A has just expressed his point of view and now attendee B is expressing an opposite point of view and pointing out what is wrong in A's point of view. It would be much better if the video streams of both A and B can be displayed, for example side by side, so that other attendees can see clearly not only B's video but also A's video in order see A's emotion when B is defending his point of view. Attendee A may be calm, angry, or maybe eager to disagree.

    With contextual video of the previous speaker, the user experience in an online video conference will be much more natural and immersive. Attendees can derive much more information in a contextual video conference.

time. With the previous active speaker's video stream displayed in appropriate proportions, online video conference attendees will be able to perceive more subtle information and have a better video conference experience. In the example of Figure 1, the simultaneous rendering of both current and previous active speakers may be like that shown in Figure 2.
