Abstract:
A network of interreporting participant stations configured to monitor and analyze station movement such that activity levels of the individual stations can be determined and reported across the network to alert participant stations whenever the activity level of any one of the participant stations has dropped to a pre-determined level.

Abstract:
One embodiment of the present invention sets forth a technique for adapting playback bit rate in a content delivery system based on scene complexity of the video content as well as network conditions and other performance factors. A scene complexity map of the video content indicates the complexity levels of different scenes within the video content. Using the scene complexity map, a content player may download scenes of lower scene complexity levels from video streams encoded to lower bit rates to manage the bandwidth consumed to download the video content and allow for the downloading of scenes of higher complexity levels from video streams encoded to higher bit rates.
Abstract:
Embodiments of the present invention set forth techniques for a content player to stream a media file using multiple network connections. To stream the media file, the content player downloads metadata associated with a requested media file, establishes a network connection with multiple content servers (or multiple network connections with a single content server or both) and begins requesting portions of the media file. In response, the requested portions are transmitted to the content player. The content player may employ a predictive multi-connection scheduling approach to determine which network connection to use in downloading a given chunk.
Abstract:
One embodiment of the present invention sets forth a technique for selecting a content distribution network (CDN) comprising at least one content server, from a plurality of CDNs, and a playing digital content file from the CDN on a content player. Selecting the CDN is based on a rank order of CDNs, an assigned weight value for each CDN, and a bandwidth measured between the content player and each CDN. Advantageously, a given content player may select a CDN based on prevailing network and CDN loading conditions, thereby increasing overall robustness and reliability when downloading digital content file from a CDN.
Abstract:
A method for directly measuring the area of a topological surface with an arbitrary boundary shape lying in a fixed elevation different from a fixed surrounding surface elevation relies upon binocular stereo vision. Three stereo correlation measurements are made, one over a window entirely within the surface of interest, a second over a window outside the surface of interest and within the surrounding area, and a third over a window fully containing the surface of interest as well as some of the surrounding area. The correlation measured in the third case is the linear sum of the correlation value over each of the first two cases weighted by the proportion of the window that the two surfaces occupy.

Abstract:
One embodiment of the present invention sets forth a technique for providing a variation of digital content that is based on a client-specified context token. Localized digital assets, e.g., graphics resources, video resource, audio resources, and text string resources, are stored as a collection of records and are dynamically linked to a assemble a software system based on the client-specified context token to generate the variation of digital content. The client receives the assembled variation of the digital content including the localized digital assets specified by the client-provided context.

Abstract:
One embodiment of the present invention sets forth a technique for recommending digital content to a user of a digital content application based on continually learned patterns of behavior. Based on metrics collected from a current session of the digital content application, properties associated with one or more users interacting with the application are inferred. The inferred properties are matched against previously defined patterns of behavior to identify digital content that could be presented to the one or more users for optional selection.
