Abstract: Systems and methods for error resilient transmission and for random access in video communication systems are provided. The video communication systems are based on single-layer, scalable video, or simulcast video coding with temporal scalability, which may be used in video communication systems. A set of video frames or pictures in a video signal transmission is designated for reliable or guaranteed delivery to receivers using secure or high reliability links, or by retransmission techniques. The reliably-delivered video frames are used as reference pictures for resynchronization of receivers with the transmitted video signal after error incidence and for random access.

Abstract: 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.

Abstract: An autodiscovery feature with an easy-to-use interface is provided to automatically collect metadata about electronic services for use within a business enterprise and to store that metadata in a metadata repository. The autodiscovery feature is used to create autodiscovery queries that are sent to electronic services to collect from the services' digests specified metadata useful for identifying the functionality of those services and integrating the services into business processes. Digests, such as RSS feeds and Atom feeds, are typically created by services to include useful metadata, such as the title of a service, the URL link to a description of the service, a brief description of the service, the publication date of the service, and other data. Autodiscovery queries can thus collect services' relevant metadata and store it in a business enterprise's metadata repository, so that the services' functionality can be quickly identified and used for business processes.

Abstract: A method and apparatus to employ a service proxy to personalize service messages by automatically supplying the interface parameters used for communications between a Service provider and its client businesses. The service proxy does this according to context parameters that the client businesses specify during configuration of the messages used to communicate with one or more services. For simpler administration, the context variables may be organized in multiple kinds of hierarchies by which communications parameters specified at a higher level are automatically applied to categories at a lower level, although parameters specified directly for a lower-level category will override parameters from a higher category.
