  • Patent number: 8793391
    Abstract: The described system and method provide joint rate control and scalable stream adaptation for multiple clients concurrently competing for the same access networks. For each such client, an optimization problem is constructed and solved to determine the streaming rate over each access network, the video packets to be transmitted, and the access network over which each video packet is sent. The rate control and stream adaptation problem is constructed as an integer program in an embodiment of the invention, with an objective to minimize a cost function of the expected video distortion. Randomized packet scheduling is accounted for in an embodiment of the invention by relaxing the integer program into real-valued optimization programs and deriving convex programming approximations.

  • Patent number: 8352832
    Abstract: An error correction code includes a separate error code portion for each of two or more separate burst erasure durations (or burst error durations). For each burst erasure duration, the code can be employed to recover from the burst erasure with a different delay time. Each error code portion has a particular parameter for burst duration (B) and delay (T), meaning that the code can be used to recover from a burst erasure of duration B with delay T. Each error code portion is based on separating the source symbols into sub-symbols and diagonally interleaving the sub-symbols based on the (B,T) parameters for the error code portion. Accordingly, different burst erasures are recovered from with different delays.

  • Patent number: 8310394
    Abstract: A method and apparatus for communicating over a network is provided. The method includes selecting between location-sensing methods for an LBA, such as between GPS and network triangulation. For each location-sensing method, a dynamic determination is made as to whether the accuracy of the location-sensing method, in the current environment, meets the application requirements. If two or more location-sensing methods meet the application requirements, then, location-sensing method selected is the location-sensing method that, from among the location-sensing methods that meet the application requirement, consumes the least power. Otherwise, the location-sensing method that is most accurate for the current environment is selected.
