Abstract: The technology disclosed further relates to distribution of live streaming sources during a video collaboration session. In particular, it relates to receiving or placing an outside call from or to at least one remote limited participant to be joined with an ongoing video collaboration session on a display wall that combines multiple live streaming sources, locating a template that identifies at least one live streaming source selected from the ongoing video collaboration session to transmit to the remote limited participant, and causing a copy of the selected live streaming source to be directed to the remote limited participant upon connection to the ongoing video collaboration session.

Abstract: A method of licensing software to a particular instance of a virtual machine that is being run as part of an Active Directory domain. Since a virtual machine is a simulation of a physical machine, i.e. a computer, it can easily be cloned to produce an exact duplicate. This poses a problem when it is desired to license an instance of software for use only on a particular virtual machine. The technology disclosed allows for software to be licensed for execution only on a particular instance of a virtual machine that is being run as part of an Active Directory domain.

Abstract: A method and system for gracefully reducing demands for shared decompression resources required to present multiple video streams concurrently such that their streaming video content is simultaneously available for further processing or display. In particular, it relates to the use of presentation time stamps or incoming frames with reference to a time base dock and a threshold to determine if the decompression resources are falling behind in their ability to process incoming frames in real time. If this occurs then frames arc dropped, i.e. discarded without being decompressed, with preference given to dropping incremental frames rather than key frames.

Abstract: A method and system for gracefully reducing demands for shared decompression resources required to present multiple video streams concurrently such that their streaming video content is simultaneously available for further processing or display. In particular, it relates to the use of presentation time stamps for incoming frames with reference to a time base clock and a threshold to determine if the decompression resources are falling behind in their ability to process incoming frames in real time. If this occurs then frames are dropped, i.e. discarded without being decompressed, with preference given to dropping incremental frames rather than key frames.
