US Patent:

43342442, Jun 8, 1982

Filed:

Jul 28, 1980

Appl. No.:

6/173005

Inventors:

James K. Chan - Cerritos CA
Curtis L. May - San Pedro CA
Allan Spooner - Cypress CA

Assignee:

Magnavox Government and Industrial Electronics Company - Fort Wayne IN

International Classification:

H04N 514

US Classification:

358166

Abstract:

An image enhancement system in which a running average of a group of digitized samples of a video signal and a median of a group of digitized samples are processed to form a gradient sample. The gradient sample is scaled in response to the noise level of the video signal. The gradient samples, average samples, and medium samples are combined by a processor which generates a corresponding sequence of output samples that are converted into an enhanced video signal from which an image is produced. The processor provides image edge enhancement for high gradients while providing increased noise filtering for low gradients.

Appl. No.:

6/133606

Inventors:

Curtis L. May - San Pedro CA

Assignee:

Magnavox Government & Industrial Electronics - Fort Wayne IN

International Classification:

H04N 521

US Classification:

358167

Abstract:

A noise reduction filter for a television receiver in which two running averages of video signal amplitude are generated over regions of the video picture where the brightness level is substantially constant. One or the other of the averages is used to control intensity to obtain a reduction of random noise in the video signal. In areas of the picture where rapid changes in intensity occur, the averages are not used in favor of the unmodified video signal.

International Classification:

H04N 21/242
H04L 65/60
H04N 21/234
H04N 21/2387

Abstract:

Methods, systems, and media for adjusting quality level during synchronized media content presentation are provided. In some embodiments, the method comprises: transmitting, from a server to a first user device, first media content data corresponding to a first stream of a media content item and from the server to a second user device, second media content data corresponding to a second stream of the media content item, wherein the first media content data is to be stored in a buffer of the first user device, and wherein the second media content data is to be stored in a buffer of the second user device; transmitting, from the server to the first user device and to the second user device, instructions that cause the first user device and the second user device to begin presenting the media content item simultaneously; determining, by the server, that the first media content data is being stored in the buffer of the first user device at a slower rate than the second media content data is being stored in the buffer of the second user device; in response to determining that the first media content data is being stored in the buffer of the first user device at a slower rate than the second media content data is being stored in the buffer of the second user device, selecting a third stream of the media content item corresponding to the first stream of the media content item, wherein the third stream of the media content item has a lower quality level than the first stream of the media content item; and transmitting third media content data corresponding to the third stream of the media content item to the first user device.
