USING THE LOCATION OF A NEAR-END USER IN A VIDEO STREAM TO ADJUST AUDIO SETTINGS OF A FAR-END SYSTEM
First Claim
1. A method for adjusting sound emitted by a far-end system, comprising:
- receiving, by the far-end system, a video stream and an audio stream captured by a near-end system;
determining an amount of area in a first frame of the video stream occupied by a near-end audio source;
determining a first set of audio parameters to apply to the audio stream based on the determined amount of area in the first frame of the video stream occupied by the near-end audio source; and
playing the audio stream using the first set of audio parameters to emit sound through one or more transducers in a speaker system of the far-end system.

Abstract
A video conferencing system is described that includes a near-end and a far-end system. The near-end system records both audio and video of one or more users proximate to the near-end system. This recorded audio and video is transmitted to the far-end system through the data connection. The video stream and/or one or more settings of the recording camera are analyzed to determine the amount of a video frame occupied by the recorded user(s). The video conferencing system may directly analyze the video frames themselves and/or a zoom setting of the recording camera to determine a ratio or percentage of the video frame occupied by the recorded user(s). By analyzing video frames associated with an audio stream, the video conferencing system may drive a speaker array of the far-end system to more accurately reproduce sound content based on the position of the recorded user in a video frame.

11. An article of manufacture, comprising:
-
a non-transitory machine-readable storage medium that stores instructions which, when executed by a processor in a computer, determining an amount of area in a first frame of a video stream occupied by a near-end audio source, wherein the video stream is captured by a near-end system along with a corresponding audio stream; determine a first set of audio parameters to apply to the audio stream based on the determined amount of area in the first frame of the video stream occupied by the near-end audio source; and playing the audio stream using the first set of audio parameters to emit sound through one or more transducers in a speaker system of a far-end system. - View Dependent Claims (12, 13, 14, 15, 16, 17)
