Abstract: Methods for the deployment of an image servicing platform over a mobile wireless network ate described. A mobile multimedia service controller (MMSC) includes a video gateway that is capable of transcoding among different video formats supported by an imaging service platform. The MMSC can be connected over a network to a download server that provides updates to a transcoder application and a video image application.

Abstract: Systems and methods for video communication services are presented herein. In particular, systems and methods in which multiple participants can simultaneously create and share video in real-time are presented herein. Other systems and methods are also presented herein.

Abstract: Systems, methods, and apparatuses of providing and processing video data for delivery to mobile devices.

Abstract: A system, method and computer program product provide finer rate control in data compression by processing a data stream through a plurality of parallel subbands, wherein a first subband processes the data differently than a second subband. Separate shift quantization parameters for each separate run-of-zeros compressed storage area or pile can be provided, instead of a single common shift parameter for every coefficient as in the prior art. The parameter value for each such area or pile can be recorded in the compressed output file. The separate shift quantization parameters can also be adjusted dynamically as data is being compressed.

Abstract: Scalable techniques for rendering emissions represented using segments of streaming data, the emissions being potentially perceivable from many points of perception and the emissions and the points of perception having relationships that vary in real time. The techniques filter the segments by determining for a time slice whether a given emission is perceptible to a given point of perception. If it is not, the segments of streaming data representing the emission are not used to render the emissions as perceived from the given point of perception. The techniques are used in networked virtual environments to render audio emissions at clients in a networked virtual reality system. With audio emissions, one determinant of whether a given emission is perceivable at a given point of perception is whether psychoacoustic properties of other emissions mask the given emission.
