Controlling video display mode in a video conferencing system
First Claim
1. A method, comprising:
- receiving an audio signal from each of a plurality of video conferencing system locations;
determining an accumulated amount of the audio signal from each of one or more of the audio signals; and
determining a display mode for at least one of the video conferencing system locations based on said determining, wherein the display mode is determined from two or more possible display modes.

Abstract
System and method for controlling video display modes in a video conferencing system. An audio signal from each of a plurality of video conferencing system locations may be received. An accumulated amount of audio signal may be determined from each of one or more of the audio signals. Subsequently, a display mode of two or more possible display modes may be determined for at least one of the video conferencing system locations based on the determined accumulated audio signal. Determining the accumulated audio signal may comprise determining a signal metric for each of one or more of the audio signals using an integrated form of the signal. The method may include comparing accumulated amounts of audio signal from one or more audio signals with at least one accumulation threshold. The display mode may also be determined based on the comparison between the accumulated audio signal and at least one accumulation threshold.

17. A method for automatically determining a display mode for a display device comprising the steps of:
-
(a) receiving a signal from each of multiple endpoints;
(b) monitoring an amount of audio signal from each of the multiple endpoints;
(c) comparing the amount of audio signal from each of the multiple endpoints with predefined parameters; and
(d) determining a display mode from available display modes, wherein available display modes are single-window display and multiple-window display, based on step (c);

23. A system, comprising:
-
a plurality of video conferencing systems, wherein the plurality of video conferencing systems are coupled through a network and wherein the plurality of video conferencing systems provide video and audio signals of participants using the respective systems;
a signal integrator, wherein the signal integrator determines an amount of accumulated audio signal for each of the plurality of video conferencing systems; and
a mode switch coupled to the signal integrator and operable to select a display mode based on the amount of accumulated audio signal for each of the plurality of video conferencing systems - View Dependent Claims (24, 25, 26)

27. A switching system for automatically determining a display mode for a video display device comprising:
-
an integrator configured to determine an amount of audio signal of each of a plurality of audio signals, the signals being from a source at each of multiple endpoints; and
a switching processor coupled to the integrator and to a video switching module, configured to determine an appropriate display mode from the available display modes, wherein available display modes are single-window display and multiple-window display, based upon a comparison of the integrated audio signal energy of each of the signals with at least one predefined parameter. - View Dependent Claims (28)
