Filed:

Mar 6, 2003

Appl. No.:

10/384232

Inventors:

Mark Anthony Pereira - Livermore CA, US

Assignee:

NVIDIA Corporation - Santa Clara CA

International Classification:

G06F 15/16
G06F 15/167

US Classification:

709231, 709203, 709216, 709219

Abstract:

Method and system for broadcasting live data over a network are described. In one embodiment, live data is accessed. Next, a first client is authenticated. The live data is then broadcast to a first client, wherein the first client is capable of buffering and re-transmitting the live data. Next, a second client is authenticated. A list of clients receiving the live data is then sent to the second client. The second client then selects the first client from the list, contacts the first client, and then receives the live data from the first client.

NVIDIA Corporation - Santa Clara CA

International Classification:

G06F 17/00
H04B 3/00

US Classification:

700 94, 381 77, 381 81

Abstract:

A user can assign different audio data streams to different output channels of a single audio card using substantially conventional APIs, device drivers, and Audio Codec Interfaces (ACIs). An Application Processing Unit (APU) sequences audio data streams in accordance with a user's output channel assignment.

Appl. No.:

10/695684

Inventors:

Mark Pereira - Livermore CA, US

Assignee:

NVIDIA Corporation - Santa Clara CA

International Classification:

H04B 3/00

US Classification:

381 77, 381 79, 381387, 381 91, 381 92

Abstract:

Embodiments of the present invention provide an audio-based position tracking system. The position tracking systems comprises one or more speakers, an array of microphones and a computing device. The speaker is located at a fixed position and transmits an audio signal. The microphone array is mounted upon a moving object and receives the audio signal. The computing device determines a position of the moving object as a function of the delay of the audio signal received by each microphone in the array.

Appl. No.:

10/229605

Inventors:

Mark A. Pereira - Livermore CA, US

Assignee:

NVIDIA Corporation - Santa Clara CA

International Classification:

H04N 5/928

US Classification:

386339, 704500

Abstract:

A system and method are provided for time scaling playback of digital audio signals with associated digital video signals. Initially, the digital video signals and the digital audio signals are received. Next, the digital audio signals are processed for the time scaling thereof while substantially preserving the frequency pitch of the digital audio signals. The processed audio signals are then encoded. Such encoded audio signals are then outputted for accelerated playback with the associated digital video signals.

US Classification:

713323, 381 58, 381 59, 714450

Abstract:

One embodiment of the present invention sets forth a method for managing a power state of an audio device resident in a graphics processing unit. The method includes the steps of directing audio data originated from a client application via an audio path in an audio driver stack to the audio device, determining whether an active stream of audio data along the audio path is present in response to a notification of an attempt to shut down the graphics processing unit, and requesting a plug and play manager to disable the audio device, if no active stream of audio data is present along the audio path.
