Apparatus and method for presenting audio in a video teleconference
View Patent ↗An advanced video teleconferencing (AVTC) system uniquely combines a number of features to promote a realistic “same room” experience for meeting participants. These features include an autodirector to select audio and video sources and to compose shots, a collaboration interface for each participant to communicate nonverbal information, directional LEDs to privately alert participants, audio reflected from the main display, and a collaborative table to share a video of objects or papers on a table. When implemented with sufficient bandwidth for take advantage of these features and to keep latency time low, this AVTC system results in a highly realistic and productive teleconferencing experience.
1. An apparatus for presenting audio in a video teleconference comprising:
a display means viewable by at least one participant;
at least one audio source; and
a horizontal support for said display means;
wherein said at least one audio source is recessed beneath a surface of said support so that said support substantially obstructs direct transmission of said sound from said at least one audio source to said at least one participant;
wherein said at least one audio source is positioned so that sound emanating from said at least one audio source is reflected from a surface of said display means towards said at least one participant.
2. The apparatus of claim 1 , wherein said at least one audio source comprises a directional audio speaker.
3. The apparatus of claim 1 , wherein said surface of said display means comprises any of:
a front surface of a monitor;
a surface of a wall;
a projection screen; and
a beam splitter.
4. The apparatus of claim 1 , wherein said horizontal support comprises a table at which said at least one participant is seated.
5. The apparatus of claim 1 , wherein said surface of said display means is forwardly inclined so that the angle between said surface of said display means and said surface of said horizontal support is less than 90 degrees.
6. The apparatus of claim 5 , wherein
said angle between said surface of said display means and said surface of said horizontal support is selected to create an illusion that said sound originates from said surface of said display means.
7. A method of presenting audio in a video teleconference comprising the steps of:
providing a display means viewable by at least one conference participant;
and a horizontal support for said display means;
recessing at least one audio source beneath a surface of said horizontal support so that said support substantially obstructs direct transmission of said sound from said at least one audio source to said at least one participant;
positioning said at least one audio source so that sound emanating from said at least one audio source is reflected from a surface of said display means towards said at least one participant.
8. The method of claim 7 , wherein said at least one audio source comprises a directional audio speaker.
9. The method of claim 7 , wherein said surface of said display means comprises any of:
a front surface of a monitor;
a surface of a wall;
a projection screen; and
a beam splitter.
10. The method of claim 7 , wherein said support comprises a table at which said at least one participant is seated.
11. The method of claim 7 , further comprising the step of: inclining said surface of said display means in a forward manner relative to said surface of said support so that the angle between said surface of said display means and said surface of said support is less than 90 degrees.
12. The method of claim 11 , further comprising the step of:
selecting said angle between said surface of said display means and said surface of said horizontal support to create an illusion that said sound originates from said surface of said display means.
