摘要:
Techniques to generate a visual composition for a multimedia conference event are described. An apparatus may comprise a visual composition component operative to generate a visual composition for a multimedia conference event. The visual composition component may comprise a video decoder module operative to decode multiple media streams for a multimedia conference event, an active speaker detector module operative to detect a participant in a decoded media stream as an active speaker, a media stream manager module operative to map the decoded media stream with the active speaker to an active display frame and the other decoded media streams to non-active display frames, and a visual composition generator module operative to generate a visual composition with a participant roster having the active and non-active display frames positioned in a predetermined order. Other embodiments are described and claimed.
