Apparatus And Method For Maintaining Synchronization Of Multiple Delayed Signals

View page
US Patent:
6392707, May 21, 2002
Filed:
Jul 28, 2000
Appl. No.:
09/627618
Inventors:
J. Carl Cooper - Monte Sereno CA
Howard Loveless - Ben Lomond CA
David Wallen - San Francisco CA
Mirko Vojnovic - Santa Clara CA
Assignee:
Pixel Instruments Corp. - Los Gatos CA
International Classification:
H04N 9475
US Classification:
348515, 348512
Abstract:
This invention is a method and apparatus for delaying video type signals along with one or more secondary signals having a timing relationship to the video type signal. The delay maintains the timing relationship between the video type signal nd secondary signals. Operation to mute or otherwise modify the secondary signals upon the loss or corruption of the video type signal is shown. The selection of one of a plurality of reference signal candidates is shown along with the use of the input signal to provide a fixed delay.

Apparatus And Method For Processing Television Signals

US Patent:
6469741, Oct 22, 2002
Filed:
May 2, 2001
Appl. No.:
09/848582
Inventors:
J. Carl Cooper - Monte Sereno CA
Howard Loveless - Ben Lomond CA
David Wallen - San Francisco CA
Mirko Vojnovic - Santa Clara CA
Assignee:
Pixel Instruments Corp. - Los Gatos CA
International Classification:
H04N 701
US Classification:
348441, 348571
Abstract:
This invention is an apparatus and method for processing television signals and in particular high quality video type signals in analog or digital form. The preferred embodiments utilizes digital storage along with oversampling, interpolation and various filtering in recursive and nonrecursive form to provide fixed or variably delayed output video signals wherein the artifacts and distortion of the video is kept to low levels.

Apparatus And Method For Digital Processing Of Analog Television Signals

US Patent:
6989869, Jan 24, 2006
Filed:
Jul 24, 2002
Appl. No.:
10/205648
Inventors:
J. Carl Cooper - Monte Sereno CA, US
Howard Loveless - Ben Lomond CA, US
David Wallen - San Francisco CA, US
Mirko Vojnovic - Santa Clara CA, US
Assignee:
Pixel Instruments Corp. - Los Gatos CA
International Classification:
H04N 7/01
H04N 11/20
US Classification:
348441, 347571
Abstract:
This invention is an apparatus and method for digital processing of television like signals and in particular the use of oversampling and interpolation to achieve improved resolution of the digital version of such signals as compared to a digital version obtained by the use of simple A/D conversion or processing at the desired sample rate. The preferred embodiment utilizes oversampling, interpolation and various filtering in recursive and nonrecursive form to provide output video signals wherein the artifacts and distortion of the video are kept to low levels.

Apparatus And Method For Digital Processing Of Analog Television Signals

US Patent:
8072539, Dec 6, 2011
Filed:
Oct 21, 2005
Appl. No.:
11/256502
Inventors:
J. Carl Cooper - Incline Village NV, US
Howard Loveless - Ben Lomond CA, US
David Wallen - San Francisco CA, US
Mirko Vojnovic - Santa Clara CA, US
International Classification:
H04N 7/01

Tile Content-Based Image Search

US Patent:
20140012831, Jan 9, 2014
Filed:
Jul 5, 2013
Appl. No.:
13/936133
Inventors:
David Whitney Wallen - Windsor CA, US
Richard Cary Dice - San Francisco CA, US
International Classification:
G06F 17/30
US Classification:
707709, 707743
Abstract:
Images are processed by extracting a number of small, fixed size pixel arrays, here called tiles. The image is thus represented as a collection of small parts in almost cookie cutter fashion. For storage, the tile data are added to a database and indexed for fast recall. Stored images can be rescaled, possibly rotated, and inserted again for more robustness. A sample image for recall is likewise processed, the extracted tiles serving as keys to find their stored counterparts. The original image can thus be recognized from even a small portion of the original image, if the sample offers enough tiles for lookup. The invention includes an image collection module, an image processing module, a storage module, a recall module and an interactive module by which a user can query a sample image or sub-image against the stored information.

Apparatus And Method For Synchronizing Multiple Asynchronous Signals

US Patent:
59460490, Aug 31, 1999
Filed:
Dec 15, 1995
Appl. No.:
8/573468
Inventors:
J. Carl Cooper - Monte Sereno CA
Howard Loveless - Ben Lomond CA
David Wallen - San Francisco CA
Mirko Vojnovic - Santa Clara CA
Assignee:
Pixel Instruments Corp. - Los Gatos CA
International Classification:
H04N 9475
US Classification:
348513
Abstract:
This invention is a method and apparatus for synchronization high quality video like signals. The preferred embodiment is described to synchronize a plurality of mutually unsynchronized video signals as well as passing one or more associated secondary signal with each video signal with a corresponding delay. The selection of one of a plurality of reference signal candidates is shown along with the use of the input signal to provide a fixed delay.

US Patent:
55505945, Aug 27, 1996
Filed:
Jul 26, 1993
Appl. No.:
8/096240
Inventors:
J. Carl Cooper - Monte Sereno CA
David Wallen - San Francisco CA
Mirko Vojnovic - Santa Clara CA
Howard Loveless - Ben Lomond CA
Assignee:
Pixel Instruments Corp. - Los Gatos CA
International Classification:
H04N 9475
US Classification:
348513
Abstract:
This invention is a method and apparatus for synchronization of high quality video like signals. Full sync tip to peak white video is digitized in the preferred embodiment along with oversampling and interpolation so that errors are kept to unexpected low levels. The preferred embodiment is described to pass one or more secondary signal with the video signal in a separate parallel but time related path. The use of the input signal for a reference to allow a fixed delay is also shown.
