Abstract

A presentation system having both video for projecting images for viewing by a user and audio for broadcasting sound in which both the audio and video are under central control, the presentation system comprises a digital projector having a wireless local area network connection for displaying the images external to the projector for viewing by the user, and for permitting connection to devices wirelessly connected to the local area network; a processor having a wireless local area network connection which processor includes digital images which are transmitted to the projector for display, and which said processor permits connection to devices wirelessly connected to the local area network; audio speakers having a wireless local area network connection for projecting audio associated with the images or audio from an individual, and for permitting connection to devices wirelessly connected to the local area network; and a central command processor having a wireless local area network connection for directing the display of images and audio being broadcast, and permitting connection to devices wireless connected to the local area network.

Claims

1. A presentation system having both video for projecting images for viewing by a user and audio for broadcasting sound in which both the audio and video are under central control over a wireless local area network, the presentation system comprising:

(a) a digital projector having a wireless local area network connection for displaying the images external to the projector for viewing by the user, and for permitting real-time connection to devices wirelessly connected to the local area network; and

(b) a central processor having a wireless local area network connection which processor includes digital images which are transmitted in real-time to the projector for display, and which said processor permits real-time connection to devices wirelessly connected to the local area network;

wherein the central processor further includes directing the display of images and audio being broadcast both in real-time, and for permitting real-time connection to devices wirelessly connected to the local area network.

2. The presentation system as in claim 1 further comprising a plurality of speakers having a wireless local area network connection for permitting connection to devices wireless connected to the local area network, and for permitting remote audio broadcasting.

3. The presentation system as in claim 1, wherein the local area network connections include real-time elements for permitting real-time audio broadcasting.

4. The presentation system as in claim 1 further comprising a camera having a wireless local area network connection for permitting connection to devices wireless connected to the local area network, and for permitting transmission of images from the camera to the projector for display.

5. The presentation system as in claim 1 further comprising a local area network access point connected to the local area network connections for permitting access to other local area networks.

6. The presentation system as in claim 1 further comprising a telephone interface having a local area network connection connected to the local area network connections for permitting telephone conferencing.

7. The presentation system as in claim 1 further comprising a remote control having a local area network connection for permitting remote control of other devices connected to the local area network.

8. The presentation system as in claim 1 further comprising presentation framework software having components that are respectively executed on all presentation processors and devices and allows for an ad-hoc discovery of devices as they enter the presentation environment, creates and destroys connections, and delivers the device control to the user.

9. The presentation system as in claim 1 further comprising lighting having a local area network connection for permitting selective dimming or brightening.

10. A presentation system having both video for projecting images for viewing by a user, and audio for broadcasting sound in which both the audio and video are under central control, the presentation system comprising:

(a) a digital projector having a wireless local area network connection for displaying the images external to the projector for viewing by the user, and for permitting real-time connection to devices wirelessly connected to the local area network, wherein the digital projector includes a processor having a wireless local area network connection, and having digital images for display; and

(b) a central command processor having a wireless local area network connection for directing the display of images and audio being broadcast both in real-time, and for permitting real-time connection to devices wireless connected to the local area network.

11. The presentation system as in claim 10 further comprising a plurality of speakers having a wireless local area network connection for permitting connection to devices wireless connected to the local area network, and for permitting remote audio broadcasting.

12. The presentation system as in claim 10, wherein the local area network connections include real-time elements for permitting real-time audio broadcasting.

13. The presentation system as in claim 10 further comprising a camera having a wireless local area network connection for permitting connection to devices wirelessly connected to the local area network, and for permitting transmission of images from the camera to the projector for display.

14. The presentation system as in claim 10 further comprising a local area network gateway connected to the local area network connections for permitting access to other local area networks.

15. The presentation system as in claim 10 further comprising a telephone interface having a local area network connection connected to the local area network connections for permitting telephone conferencing.

16. The presentation system as in claim 10 further comprising a remote control having a local area network connection for permitting remote control of other devices connected to the local area network.

17. The presentation system as in claim 10 further comprising presentation framework software having components that are respectively executed on all presentation processors and devices and allows for an ad-hoc dicovery of devices as they enter the presentation environment, creates and destroys connections, and delivers the device control to the user.

18. The presentation system as in claim 10 further comprising lighting having a local area network connection for permitting selective dimming or brightening.
