Digital Video Media Duplication Or Transmission Quality Measurement

US Patent:
7522776, Apr 21, 2009
Filed:
Apr 18, 2008
Appl. No.:
12/105678
Inventors:
Joseph M. Kahan - Houston TX,
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06K 9/36
G06K 9/46
US Classification:
382233, 382236, 382250, 382251, 382190, 382305, 37524001, 37524018
Abstract:
A system and method for measuring video quality of a video image, wherein the system comprises a source device comprising an original video image; a receiver comprising a received video image; a storage device adapted to store video images from the source device and the receiver; a decoder connected to the receiver, wherein the decoder is adapted to compare display attributes of the received video image with creation attributes of the original video image; and a processor adapted to attribute an objective standard to the received video image based on the comparison between the display attributes and the creation attributes, wherein the objective standard comprises a video pixel size component, a video motion rating component, a video clarity rating component, and a pixel color rating component.

Sound Card Having Feedback Calibration Loop

US Patent:
8130981, Mar 6, 2012
Filed:
Mar 25, 2008
Appl. No.:
12/054494
Inventors:
Joseph M. Kahan - Houston TX,
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H03F 99/00
US Classification:
381120, 381121, 381104, 700 94
Abstract:
Disclosed are a sound card and a method for limiting inputs to and outputs from that computer sound card. Specifically, the voltage of a feedback connection between the input and output of a sound card amplifier is increased from minimum voltage until an over-saturation condition occurs. This finds the “output voltage limit. ” Thereafter, the output voltage of the amplifier is restricted to the output voltage limit. The feedback connection is then terminated and the voltage of the signal being supplied to the amplifier is increased from minimum voltage until the over-saturation condition again occurs. This finds the “input voltage limit. ” Thereafter, the input supplied to the amplifier is restricted to the input voltage limit.

Sound Card Having Feedback Calibration Loop

US Patent:
2006006, Mar 23, 2006
Filed:
Sep 22, 2004
Appl. No.:
10/947086
Inventors:
Joseph Kahan - Houston TX,
International Classification:
H03F 21/00
G06F 17/00
US Classification:
381120000, 700094000
Abstract:
A method of, and apparatus for, limiting inputs to and outputs from a computer sound card forms a feedback connection between the input and output of the sound card amplifier. The voltage of the feedback connection is increased from minimum voltage until an over-saturation condition occurs. This finds the “output voltage limit.” Thereafter, the output voltage of the amplifier is restricted to the output voltage limit. The feedback connection is then terminated and the voltage of the signal being supplied to the amplifier is increased from minimum voltage until the over-saturation condition again occurs. This finds the “input voltage limit.” Thereafter, the input supplied to the amplifier is restricted to the input voltage limit.
