摘要： In accordance with the present invention, a source content clip having a multiple constituent tracks of information is processed so that each constituent track is processed independently, and operations to be performed for each track can be independently selected. An optimal combination of the processed tracks for the clip (the prepped content) can be selected at transport time in accordance with current network conditions for efficient transport and to maximize the quality-of-service experienced at the receiving device. In this way, when the processed content is to be provided to a receiving device across the network, the constituent processed tracks can be selected and composed into a completed clip at the time of transport such that desired quality-of- service parameters can be satisfied while best utilizing the network resources available.

摘要： A method for graphics rendering adaptation by a server that includes a graphics rendering engine that generates graphic video data and provides the video data via a communication resource to a client. The method includes monitoring one or both of communication and computation constraint conditions associated with the graphics rendering engine and the communication resource. At least one rendering parameter used by the graphics rendering engine is set based upon a level of communication constraint or computation constraint. Monitoring and setting are repeated to adapt rendering based upon changes in one or both of communication and computation constraints. In preferred embodiments, encoding adaptation also responds to bit rate constraints and rendering is optimized based upon a given bit rate. Rendering parameters and their effect on communication and computation costs have been determined and optimized. A preferred application is for a gaming processor running on a cloud based or data center server that services mobile clients over a wireless network for graphics intensive applications, such as massively multi-player online role playing games, or augmented reality.

摘要： A method for monitoring a wireless channel or wireless network. Preferably, the method and system monitors a web-based network. Active data probing is used to estimate bandwidth availability when no a-priori knowledge of the current channel or network condition is available, and passive monitoring is used to track ongoing web traffic in estimating the current bandwidth available. Data probes are selected that are dynamically customized based on application requirements and the network variability observed in view of a balancing between accuracy of the bandwidth estimation and the potential overhead in terms of time consumed and additional traffic used. In this way, under specified limits of overhead, the active probing attempts to achieve best-effort network bandwidth estimation, and the passive monitoring tracks ongoing web traffic in estimating the current bandwidth available.
