Abstract: A method for delivering video data from a server in a content delivery network (CDN). Video preferences of active users of a cell are determined. Video data is cached at one or more base station nodes disposed in a radio access network (RAN), wherein the video data is cached in one or more micro-caches according to a caching policy that is based on the determined video preferences. A request is received for video data. If the cached video data includes the requested video data, the cached video data is served from the RAN cache. If the cached video data does not include the requested video data, the requested video is fetched from the CDN according to a scheduling approach that considers Quality of Experience (QoE).

Abstract: A method and system are provided for wireless multimedia customization for different access networks with variable network conditions and device types. In one aspect, when a multimedia content clip is available, the clip is processed for transport by processing it in accordance with different options for the content clip in an optimized way that helps dynamic customization. For example, instead of preparing a version of the entire content clip, targeted for a particular network condition and target device characteristics, or creating a separate processed clip for each compression parameter available, a set of content ingredients are generated that can address a wide range of network conditions even through dynamic fluctuations in conditions and device characteristics.

Abstract: 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.

Abstract: Digital video content is processed for delivery over a communications channel by segmenting the digital video content into one or more regions of interest (ROI) in accordance with content signature of the video content and encoding the digital video content in accordance with the ROI segmentation and the communications channel.

Abstract: A method and system for wireless data communication. A request is accepted for communication of a data collection including a plurality of data objects. For each of the plurality of data objects, content importance and error resilience properties are evaluated. A transmission order of the data objects is determined based upon evaluated content importance, error resilience properties, past channel conditions and predicted channel conditions, and one or more data objects are selected based on the determined order. An error control level is selected for transmission of data packets for communicating the selected data objects based upon error resilience properties and current channel conditions to achieve communication of the data collection.

Abstract: 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.

Abstract: Apparatus and method suitable for improving reliability of collected sensor data over a network. One or more transient errors are predicted and corrected using correlation of collected data. For example, sensor data can be collected from one or more sensor nodes in a network. A device other than a sensor node can use the data to develop a predictive model based upon inherent redundancy in the sensor data, and correct one or more later-received values deemed unreliable.

Content, such as advertising customized to user profile and user location, may be conveniently inserted into the live content. Source-to-screen delay from sources to receiving devices is reduced and channel switching is supported.
