Abstract:
The apparatus and method described herein provides for creating multiple spatial patterns, such as magnetic patterns on credit cards. The invention includes storage of information from which patterns may be created, a pattern creation device for creating the spatial patterns, and control whereby the information which is stored is selectively utilized to cause the pattern creation. This allows multiple desired patterns to be simulated, allowing convenient replacement of a number of separate pattern carrying devices.
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.
Abstract:
Measurement of the relative timing between images and associated information, for example video and audio. Image mutual event characteristics are recognized in the images and associated mutual event characteristics are recognized in the associated information. The image mutual events and associated mutual events are compared to determine their occurrences, one relative to the other as a measure of relative timing. Particular operation with audio and video signals is described.

Abstract:
Method, system, and program product for measuring audio video synchronization. This is done by first acquiring audio video information into an audio video synchronization system. The step of data acquisition is followed by analyzing the audio information, and analyzing the video information. In this phase audio and video information is analyzed, decision boundaries for Audio and Video MuEv-s are determined, and related Audio and Video MuEv-s are correlated. In Analysis Phase Audio and Video MuEv-s are calculated from the audio and video information, and the audio and video information is classified into vowel sounds including AA, EE, OO, silence, and unclassified phonemes This information is used to determine and associate a dominant audio class in a video frame. Matching locations are determined, and the offset of video and audio is determined.
Abstract:
The present disclosure teaches a method and apparatus for allowing a user to select and view one or multiple programs at random whenever he desires and to suspend viewing in the middle of a program to accommodate an interruption and to continue viewing after the interruption without missing any of the program. In addition, previously stored programs may be viewed at accelerated or decelerated speed, or repeated or portions reviewed, to allow the user to review such in other than real time.
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.
Abstract:
An apparatus and method is disclosed for converting an input signal having frequency related information sustained over a first duration of time into an output signal sustained over a second duration of time at substantially the same first frequency by adding or subtracting to the effective wave length of the output signal. Preferably, the signals are converted in digital form with samples added or subtracted to frequency convert the signal.
