| 20120082214 | Delay Aware Rate Control In The Context Of Hierarchical P Picture Coding - The present invention provides bit rate control techniques for a hybrid block based motion compensated predictive video encoder (e.g., H.264, as well as other video coding algorithms and standards). The techniques aim to reduce the picture-to-picture bit rate fluctuations within a prediction structure or over a short time interval that can lead to undesirable additional delay on links without over-provisioned capacity. In one embodiment of the present invention, the end to end delay is estimated. The end to end delay is used to determine limits on the modulation of the target coded picture size, with the goal of trading an acceptable amount of additional delay for a better coding efficiency. | 04-05-2012 |
| 20120072499 | SYSTEM AND METHOD FOR THE CONTROL AND MANAGEMENT OF MULTIPOINT CONFERENCE - Systems and methods for the control and management of multipoint conferences are disclosed herein, where endpoints can selectively and individually manage the streams that will be transmitted to them. Techniques are described that allow a transmitting endpoint to collect information from other receiving endpoints, or aggregated such information from servers, and process them into a single set of operating parameters that it then uses for its operation. Algorithms are described for performing conference-level show, on-demand show, show parameter aggregation and propagation, propagation of notifications. Parameters identified for describing sources in show requests include bit rate, window size, pixel rate, and frames per second. | 03-22-2012 |
| 20110292161 | Systems And Methods For Scalable Video Communication Using Multiple Cameras And Multiple Monitors - Systems and methods for performing videoconferencing using endpoints with multiple monitors and multiple cameras are disclosed herein. These endpoints are comprised of, where each node is comprised of a control unit and one or more node units, each connected to at least one monitor, camera, speaker, or microphone. Video is encoded using scalable coding, and endpoints are connected to each other over a network using an SVCS. Algorithms are described for layout management, tagging of individual streams, and use of tags for dynamic and prioritized layout management. | 12-01-2011 |
| 20110222545 | SYSTEM AND METHOD FOR RECOVERING THE DECODING ORDER OF LAYERED MEDIA IN PACKET-BASED COMMUNICATION - The present invention relates to the packet-based transmission of media that are coded using a layered representation. In particular, it relates to mechanisms for recovering the decoding order of the media packets when such media is transmitted with arbitrary ordering over one or more packet streams. | 09-15-2011 |
