Abstract

Individual adjustment of audio volume and video properties in a computer network conference environment is provided. For audio adjustment, a buffer collects incoming streams; a stream decoder decodes the buffered audio streams, a gain adjustment applies a gain increase or decrease to the individual audio stream, and a mixer combines each of the individual signals together. The gain adjustment module receives input from a user interface control associated with each participant, and adjusts the volume of that participant's stream accordingly. If a requested increase in gain would cause an overflow of the signal, only a gain increase that will avoid such overflow is applied. Video properties such as brightness, contrast and saturation are also adjustable. Properties of the user's transmitted audio and video streams are also adjustable.

Claims23

Dependent claims

A computer-implemented method comprising:

receiving, at a third device of a third participant, a first video stream from a first device of a first participant, the first video stream having an image attribute set at a first level;
determining a number of clipping events in an interval of the first video stream in which the image attribute of the first video stream overflows;
responsive to the number of clipping events exceeding a threshold:
determining a first multiplier that, responsive to application to the image attribute, prevents the image attribute from overflowing past an upper limit of values of the image attribute;
and
automatically adjusting the first level by the first multiplier;
receiving, at the third device of the third participant, a second video stream from a second device of a second participant, the second video stream having the image attribute set at a second level by adjusting a second multiplier, the second level adjusted to not exceed the upper limit and adjusted independent of the first level;
and
playing, by the third device of the third participant, the received first and second video streams, the first video stream being played having the image attribute at the adjusted first level, and the second audio stream being played having the image attribute at the second level.
