Abstract: Systems and methods for identifying and selecting a desired display device of one or more display devices for multimedia output are provided. In one embodiment, a respective identifying spatial orientation and one or more connectivity identifiers are associated with each of one or more display devices. A respective selecting spatial orientation is then received. The respective selecting spatial orientation is matched to the respective identifying spatial orientation to thereby determine the desired display device from the one or more display devices. Multimedia content is then routed from a source device to the desired display device via one of the one or more associated connectivity identifiers.

Abstract: A device for cooling a projector includes a plurality of air intakes positioned upstream from a suction fan having an integrated motor. A light source of the projector is disposed between a first air intake and the suction fan so that a first air flow, drawn by the fan through the first air intake, flows around and pulls heat away from the light source. A second air intake is positioned to admit a second air flow, also drawn by the fan, that passes through a duct positioned adjacent an upstream side of the suction fan to direct the second air flow against the fan motor. The second air flow, which has a temperature that is not substantially affected by the light source, cools the fan motor and forms an insulating air layer that protects the fan motor from being damaged by the high temperatures of the first air flow.

Abstract: An interactive and custom support kiosk is disclosed. In one embodiment, a kiosk is provided including a user attribute identification system and a region-specific linkage. The user attribute identification system may be a user language identification system where the user's preferred language may be detected. With detection of a user's preferred language, the kiosk may display a language-customized display with customized features based on the identified language. In some embodiments, the customized features may include a language-based experience format similar to a user's experience which would be expected in the user's home geography. In some examples, a second level of interaction may be provided wherein the user may be connected to a region-specific operator. The operator may provide immediate live help or assistance through the kiosk. In addition, security controls may be provided with the interactive language and custom support kiosk.

Abstract: The technology disclosed relates to enabling smooth transitioning between compressed video streams. In particular, it relates to scheduling transitions between compressed video streams to be shown in an area of a display such that while decoding, decompressing and buffering a first video stream for display, commencing decoding, decompressing and buffering of a second video stream at a predetermined time before a scheduled showing of the second video stream. It further relates to switching buffers between display of the first and second video streams at the scheduled showing of the second video stream, which results in immediate display of the second video stream without delay. In one implementation, switching between the buffers for the first and second video streams includes modifying z-ordering of display layers corresponding to the first and second video streams.

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.
