摘要： Performing conferencing without requiring communication using a specific connection port. A software module receives a function call from a conferencing application. The function call may include high-level instructions to perform a basic conferencing function, such as the communication of data from a specified buffer area. The software module then performs all of the details necessary in order to establish and maintain a connection with a conferencing server (or with one or more other participants in the case of peer-to-peer conferencing). While the conferencing application may be configured to optionally perform teleconferencing using a particular conferencing protocol and a particular conferencing connection port without the use of the software module, the software module may also be optionally used to establish, maintain, and exchanging conferencing information over an entirely different port when, for example, the usual conferencing connection port is not available.

摘要： A system and process for highlighting the current speaker on an on-going basis in each frame of a low frame-rate video of an event having multiple people in attendance is presented. In general, this is accomplished by periodically identifying an attendee that is currently speaking at a rate substantially faster than the video frame rate, and updating each frame of the video to highlight the current speaker. More particularly, an A/V source provides a video stream to a client computing device that includes delta frames interspersed between the frames of the low frame-rate video. The full video frames act as keyframes, and the delta frames provide the changes needed to modify the last displayed version of the last keyframe to highlight just the region associated with the location of a current speaker. This allows the client device to operate as a standard A/V rendering and display unit.
