摘要： A method and computing system for receiving an indication of a first user participating in a videoconference. A determination is made concerning whether bandwidth compression is preferable for the first user of the videoconference. If bandwidth compression is preferable for the first user of the videoconference: an unprocessed video stream associated with the first user is processed to generate a reduced bandwidth video stream, and the reduced bandwidth video stream is provided to a video encoder. Processing the unprocessed video stream includes performing an edge detection procedure on the unprocessed video stream.

摘要： Embodiments generally relate to presenter control during a video conference. In one embodiment, a method includes providing a user interface of a video conference between at least a first user and a second user, where the user interface displays a first user video stream in a current presenter position and displays a second user video stream in a secondary presenter position. The method also includes detecting at least one gesture from the second user, where the detecting of the at least one gesture indicates that the second user intends to be a current presenter. The method also includes causing the user interface to display the second user video stream in the current presenter position and to display the first user video stream in the secondary presenter position in response to the detecting.
