    Abstract: One embodiment of the present invention sets forth a technique for deferring license retrieval when streaming digital media content. The perceived delay between the time a user selects the protected digital media content to when playback of the protected digital media content begins is reduced because retrieval and playback of an unprotected version of a portion of the digital media content starts before the license and protected version of the digital media content is received. The unprotected version includes fast start streams of audio and video data that may encoded at a lower bit rate than the protected version in order to quickly transfer the fast start streams from the content server to the playback device.

    Abstract: One embodiment of the present invention sets forth a technique for starting playback of an audio portion of digital media content before a video portion of the digital media content is received. An advantage of the disclosed technique is that the perceived delay from the time when a user selects the digital media content to when playback of the digital media content begins is reduced. The audio may be faded-in and one or more still frames of video data may be displayed while the video stream is retrieved. Additionally, a license for DRM (Digital Rights Management) encryption of the title content may be retrieved before starting playback of the video stream, so that the digital media content that is retrieved is also protected.

    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.
