Abstract

Systems and methods that facilitate dual view video display with dual beam sound projection. Video signal from independent input sources are simultaneously and separately viewable on a display by viewer wearing shutter glasses. The sound projector preferably comprises an array of speakers configurable to project beams of independent audio signals to separate targeted locations.

Claims

1. A television system comprising

a television comprising

audio and video input connections,

a video display screen, and

a control system coupled to the audio and video input connections and video display screen, wherein the control system is configured to combine input video signals from first and second input audio-video sources coupled to the video input connection and alternately display separate images from the combined signals on the video display screen, and

first and second shutter glasses operably coupled to the control system, wherein the shutters on each of the first and second glasses are configured to switch simultaneously enabling simultaneous full screen viewing of the input video signal from the first input audio-video source through the first shutter glasses and the input video signal from the second input audio-video source through the second shutter glasses.

2. The television system of claim 1 wherein the television further comprises an integral sound projector coupled to the control system.

3. The television system of claim 2 wherein the control system and integral sound projector are configured to project a first sound beam of a first input audio signal from the first input audio-video source in a first targeted direction and a second sound beam of a second input audio signal from the second input audio-video source in a second targeted direction.

4. The television system of claim 3 wherein the control system comprises a micro processor, non-volatile memory, system control software stored on the non-volatile memory and executable on the micro processor, an on screen display controller coupled to the micro processor and the video signal input connections, an image display engine coupled to the on screen display controller and the display screen.

5. The television system of claim 4 wherein the control system further comprises an audio processor coupled to the micro processor and the sound projector.

6. The television system of claim 5 wherein the audio processor is a digital sound processor.

7. The television system of claim 6 wherein the sound projector comprises an array of speakers configurable to inject sound beams into a room that the television is located.

8. The television system of claim 7 wherein the television further comprises a menu based user control system displayable on the screen of the television and generated by the control system software.

9. The television system of claim 8 wherein the television further comprises a menu based user control system includes a graphical user interface.

10. The television system of claim 9 wherein the television further comprises a synchronizing signal transmitter configured to transmit timing signals receivable by the first and second shutter glasses to synchronize the shutters of the first and second shutter glasses with a refresh rate of the video display screen as the video display screen alternately displays separate images corresponding to each of the combined signals received from the first and second audio-video input sources.

11. A method for simultaneous full screen viewing on the display screen of a television of separate video signals from first and second audio-video input sources coupled to the television, comprising the steps of

combining first and second video signals from first and second audio-video input sources coupled to the television,

displaying on the display screen of the television the combined first and seconde video signals,

simultaneously switching shutters on a first pair of shutter glasses and shutters on a second pair of shutter glasses enabling simultaneous full screen viewing of the input video signal from the first input audio-video source through the first pair of shutter glasses and the input video signal from the second input audio-video source through the second pair of shutter glasses.

12. The method of claim 11 further comprising the step of

injecting into a viewing space from a sound projector integral with the television first and second sound beams of first and second input audio signals from the first and second input audio-video sources toward first and second targeted locations.

13. The method of claim 12 further comprising the steps of

transmitting a synchronizing signal from the television, and

receiving the synchronizing signal and synchronizing the shutters of the first and second shutter glasses with a refresh rate of the video display screen as the video display screen alternately displays separate images corresponding to each of the combined signals received from the first and second audio-video input sources.

14. The method of claim 13 further comprising the step of adjusting the direction of the first and second targeted sound beams and displaying a graphical representation of the first and second targeted sound beams.
