摘要:
Techniques are provided which allow computers with relatively less computational power to perform dynamic conversion of video from inter-frame dependent format to an independent-frame format while playing the video as it is being converted. If the conversion operation is not keeping up with the arrival of the incoming video, the video is spooled within the computer system. The playback and conversion operations proceed as the spooling is performed. Thus, to a viewer of the video, the video may appear to slow, but the playback and conversion operation proceed without losing frames.
摘要:
In one aspect, audio summaries and transition audio segments are sequentially rendered with at least one transition audio segment rendered between each pair of sequential audio summaries. Each audio summary comprises digital content summarizing at least a portion of a respective associated audio piece. In another aspect, an original audio file is annotated by embedding therein information enabling rendering of at least one audio summary contained in the annotated audio file and comprising digital content summarizing at least a portion of the original audio file. In another aspect, an original audio file is annotated by providing at least one browsable link between the original audio file and at least one audio summary comprising digital content summarizing at least a portion of the original audio file, and storing the original audio file, the at least one browsable link, and the at least one audio summary on a common portable storage medium. In another aspect, an audio piece is divided into audio segments. Acoustical features are extracted from each audio segment. Audio segments are grouped into clusters based on the extracted features. A representative audio segment is identified in each cluster. A representative audio segment is selected as an audio summary of the audio piece.

Statistical information related to performing information searches based on search templates may be automatically generated and stored in statistical records. The statistical records may be automatically updated. The statistical records may be sorted to indicate which information searches are most efficient.

An electronic messaging tracking system and method is provided that tracks messages in a single or multiprotocol messaging environment. Tracking entries are collected, stored and updated. Queries may be made regarding the status, travel path, and other criteria of any message. Queries need not include a unique identifier of the message. Users may access the message tracking system from an internal or external network.

A system for interactive video playback includes a store for holding a set of video streams and an input device for obtaining a set of action inputs. The system includes a video processor that generates the interactive video playback by switching among the video streams in response to the action inputs.

摘要:
Systems and methods for defining attributes for one or more entries in a computer implemented directory structure. The method comprises grouping a set of non-schema attributes associated with a directory entry into a multivalue schema attribute, wherein the multivalue attribute comprises values associated with each of the corresponding non-schema attributes grouped into the multivalue attribute; encoding at least one of the non-schema attributes into a string having one or more parts; and performing computing operations on the non-schema attributes in the directory entries based on content of the encoded strings defined in the multivalue attribute in which the respective non-schema attributes are grouped.
摘要:
A method for estimating motion of each of a plurality of tessels in an intermediate image relative to a reference image, which includes searching the reference image to find points that lie along epipolar lines in the reference image corresponding to upper-left and lower-right vertices of the tessel, respectively, that result in a best-matching shape; estimating a depth of each of at least two of the vertices of the tessel; and using the depth estimates of the at least two vertices of the tessel to estimate the motion of the tessel relative to the best-matching shape.
