Abstract
Video send and receive capabilities of participants are determined by the respective machines determining available combinations, as well as preferences for the receivers. Receiver capabilities are forwarded to the source for computation of negotiated video capabilities through a logic intersection of the determined capabilities based on desired number of streams and resolutions. If a resolution of a send capability exists within the receive capability, the highest frame and/or bit rate may be selected for transmission.
