Filed:

Oct 29, 2004

Appl. No.:

10/976729

Inventors:

Kenneth Abend - Huntingdon Valley PA, US
Alan Stein - Cherry Hill NJ, US

Assignee:

Allez Physionix LTD - Seattle WA

International Classification:

A61B 8/14

US Classification:

600454

Abstract:

A method and associated apparatus are disclosed for determining the location of an effective center of fluid flow in a vessel using an ultrasound apparatus. Ultrasound energy is propagated along an axis of propagation and projects upon the vessel. A Doppler-shifted signal reflected from the fluid in the vessel is received and a set of quantities expressed as a density is derived from the Doppler shifted signal for each of a set of coordinates, the density being a function of the Doppler shift in frequency associated with each of the coordinates. One of a mean, mode or median is calculated for each of the dimensions of the set of coordinates in conjunction with the density associated therewith. This calculation is repeated throughout the field of view of the vessel to define a centerline.

International Classification:

H04J 1/16
H04Q 7/24

US Classification:

370230, 370252, 370338, 370469

Abstract:

A method and apparatus are described including receiving a coded packet of content associated with a layer, receiving feedback information regarding channel conditions and applying hybrid automatic repeat request to deliver the packet based on said feedback information. The method and apparatus wherein applying hybrid automatic repeat request layer-wise further includes determining if a resource is exhausted, scheduling delivery of layered coded content packets for a layer, if the resource has not been exhausted, determining if all layered coded content packets for the layer have been transmitted, proceeding to the first determining step, if all layered coded content packets for a layer have not been transmitted, determining if an acknowledgement message has been received from a user device, determining if the resource is exhausted, if no acknowledgement has not been received and scheduling delivery of layered coded forward error correction packets, if the resource has not been exhausted.

International Classification:

H04N 7/12
H04N 9/475

US Classification:

37524001, 348731, 348518

Abstract:

A digital video apparatus provides reduced channel change times. According to an exemplary embodiment, the digital video apparatus includes at least one receiver for receiving first and second video streams representing the same program, wherein the first video stream has at least one characteristic different from the second video stream; a first signal processor for processing the first video stream to generate a first processed video stream; a second signal processor for processing the second video stream to generate a second processed video stream having a delay with respect to the first processed video stream; a renderer for rendering the second processed video stream responsive to a channel change command; and a switch for switching from the second processed video stream to the first processed video stream after the renderer begins rendering the second processed video stream, and thereby causing the renderer to begin rendering the first processed video stream.

Abstract:

A digital A/V apparatus provides reduced channel changes times and maintains synchronization between audio and video content during a channel change event. According to an exemplary embodiment, the digital A/V apparatus includes at least one signal receiver for receiving a first audio stream, a first video stream and a second video stream, wherein the first and second video streams represent the same program and the first video stream has at least one characteristic different from the second video stream; a first audio signal processor for processing the first audio stream to generate a first processed audio stream; a first video signal processor for processing the first video stream to generate a first processed video stream; a second video signal processor for processing the second video stream to generate a second processed video stream having a delay with respect to the first processed video stream; a first buffer for buffering the first processed audio stream to provide de-jittering; a renderer for rendering the first processed audio stream and the second processed video stream in response to a channel change command; a switch for switching from the second processed video stream to the first processed video stream after the renderer begins rendering the second processed video stream, and thereby causing the renderer to begin rendering the first processed video stream; and whereby synchronization between the first processed audio stream and the first processed video stream is maintained during a channel change event.

International Classification:

H04N 11/02

US Classification:

37524028, 375E0701

Abstract:

There are provided methods and apparatus for fast channel change for digital video. An apparatus includes at least one encoder for receiving normal video data and channel change video data and encoding the normal video data and the channel change video data in a normal video stream and a channel change video stream, respectively, using a common system clock to provide synchronization between the normal video stream and the channel change video stream. The normal video stream and the channel change video stream are encoded for transport separately at a transport level.
