US Patent:

6496221, Dec 17, 2002

Filed:

Nov 1, 1999

Appl. No.:

09/431160

Inventors:

Stephen Wolf - Longmont CO
Margaret H. Pinson - Boulder CO

Assignee:

The United States of America as represented by the Secretary of Commerce - Washington DC

International Classification:

H04N 1700

US Classification:

348192, 348193

Abstract:

An apparatus for measuring the quality of a video transmission or storage system when the input and output of the system may be spatially separated, when the apparatus might not have a priori knowledge of the input video, and when there exists an ancillary data channel that can be used by the apparatus. The apparatus makes continuous quality measurements by extracting features from sequences of processed input and output video frames, communicating the extracted features between the input and the output ends using an ancillary data channel of arbitrary and possible variable bandwidth, computing individual video quality parameters from the communicated features that are indicative of the various perceptual dimensions of video quality (e. g. , spatial, temporal, color), and finally calculating a composite video quality score by combining the individual video quality parameters. The accuracy of the composite video quality score generated by the apparatus depends on the bandwidth of the ancillary data channel used to communicate the extracted features, with higher capacity ancillary data channels producing greater accuracies than lower capacity ancillary data channels.

Assignee:

Sun Microsystems, Inc. - Santa Clara CA

International Classification:

G09G005/00

US Classification:

715769, 715761, 715788, 715798

Abstract:

Apparatus and methods for segmenting sets of distinct entities into groups with associated boundaries, wherein the associated boundaries have an associated logic are disclosed. The interaction of an object, a set of objects, another group, or combinations thereof with a group's associated boundary is accounted for by the logic of the invention such that the group and its associated boundary are modified with respect to the interaction.

10/084314

Inventors:

Stephen Talley - Boulder CO, US
Stephen Wolf - Superior CO, US

Assignee:

Sun Microsystems, Inc.

International Classification:

G09G005/00

US Classification:

345/703000, 345/765000, 345/778000

Abstract:

Systems and methods consistent with principles of the present invention allow localized text and user interface components to be dynamically displayed in a user interface layout. Resource strings may be used to represent localized data. The localized data may contain parameters that are associated with components of a user interface. The parameters may be integrated into a syntactical structure associated with the data. At run-time, the resource strings may be replaced with the data and the parameters may be replaced with the components. The data and components could be arranged in a user interface layout and presented to a user.

Appl. No.:

11/545801

Inventors:

Stephen Wolf - Longmont CO, US

International Classification:

G01N 37/00

US Classification:

702081000

Abstract:

A new reduced reference (RR) video calibration and quality monitoring system utilizes less than 10 kilobits/second of reference information from the source video stream. This new video calibration and quality monitoring system utilizes feature extraction techniques similar to those found in the NTIA General Video Quality Model (VQM) recently standardized by the American National Standards Institute (ANSI) and the International Telecommunication Union (ITU). Objective to subjective correlation results are presented for 18 subjectively rated data sets that include more than 2500 video clips from a wide range of video scenes and systems. The method is being implemented in a new end-to-end video-quality monitoring tool that utilizes the Internet to communicate the low bandwidth features between the source and destination ends.
