Abstract

Multicast stereoscopic video synchronization includes generating synchronizing information correlated to an image sequence that includes a series of left eye images and a series of right eye images, and transmitting a radio frequency communication signal that includes the synchronizing information.

Claims

1. A method comprising:

generating synchronizing information correlated to an image sequence that includes a series of left eye images and a series of right eye images; and

transmitting a radio frequency communication signal that includes the synchronizing information.

2. A method according to claim 1, including:

receiving the communication signal in a device having first and second shutters that each have mutually exclusive first and second operational modes, wherein each of the shutters is transmissive to radiation in the first operational mode thereof and substantially blocks transmission of radiation therethrough in the second operational mode thereof; and

switching each of the first and second shutters between the first and second operational modes thereof as a function of the synchronizing information.

3. A method according to claim 2, wherein the synchronizing information causes each of the shutters to be in the second operational mode for a time period that is longer than each of the shutters is in the first operational mode.

4. A method according to claim 1, including displaying the image sequence.

5. A method according to claim 1, including generating the synchronizing information so that it is correlated to a further image sequence that includes a further series of left eye images and a further series of right eye images, wherein the image sequences are different from each other.

6. A method according to claim 5, including separately displaying each of the image sequences.

7. A method according to claim 1, including:

generating further synchronizing information correlated to the image sequence; and

transmitting a further radio frequency communication signal that includes the further synchronizing information, the synchronizing information in one of the communication signals being different from the synchronizing information in the other of the communication signals.

8. A method according to claim 7, wherein the transmitting of the radio frequency communication signals includes transmitting the radio frequency communication signals at respective frequencies that are different from each other.

9. An apparatus comprising an information handling system that includes:

a processor that executes a synchronizing program to generate synchronizing information correlated to an image sequence that includes a series of left eye images and a series of right eye images; and

a radio frequency transmitter that transmits a wireless communication signal that includes the synchronizing information.

10. An apparatus according to claim 9, including a display device that displays the image sequence.

11. An apparatus according to claim 9, wherein the synchronizing program causes the processor to generate the synchronizing information as a function of display characteristics for a plurality of different display devices.

12. An apparatus according to claim 11, wherein the synchronizing program causes the processor to generate the synchronizing information so that it is correlated to a further image sequence that includes a further series of left eye images and a further series of right eye images and wherein two of the plurality of display devices each display a respective one of the image sequences.

13. An apparatus according to claim 9, wherein the synchronizing program causes the processor to generate the synchronizing information so that it is correlated to a further image sequence that includes a further series of left eye images and a further series of right eye images, the image sequences being different from each other.

14. An apparatus according to claim 9, wherein the information handling system includes a radio frequency receiver receiving a wireless communication signal that includes viewer device status information.

15. An apparatus according to claim 14, wherein the synchronizing program generates the synchronizing information as a function of the status information.

16. An apparatus according to claim 9, wherein the transmitter transmits a further wireless communication signal that includes the synchronizing information, wherein the communication signals are transmitted at respective frequencies that are different.

17. An apparatus according to claim 9, wherein the transmitter transmits a further wireless communication signal that includes further synchronizing information correlated to a further image sequence that includes a further series of left eye images and a further series of right eye images, the synchronizing information in one of the communication signals being different from the synchronizing information in the other of the communication signals, and both communication signals being correlated to both image sequences.

18. An apparatus according to claim 9, wherein the transmitter transmits a further wireless communication signal that includes further synchronizing information correlated to the image sequence, wherein the wireless communication signals are different from one another.

19. An apparatus comprising a viewing device that includes:

a first shutter having mutually exclusive first and second operational modes, wherein in the first operational mode the first shutter is transmissive to radiation and in the second operational mode the first shutter substantially blocks transmission of radiation therethrough;

a second shutter having mutually exclusive first and second operational modes, wherein in the first operational mode the second shutter is transmissive to radiation and in the second operational mode the second shutter substantially blocks transmission of radiation therethrough; and

a circuit that includes a communication receiver that receives radio frequency (RF) communication signals, the circuit causing each of the first and second shutters to switch between the first and second operational modes thereof in response to received communication signals.

20. An apparatus according to claim 19, including a frame supporting the first shutter, the second shutter and the circuit.

21. An apparatus according to claim 19, wherein the first shutter and the second shutter are liquid crystal display (LCD) devices.

22. An apparatus according to claim 19, wherein the circuit also includes a communication transmitter that transmits wireless viewing device communication signals.

23. An apparatus according to claim 22, wherein the communication transmitter transmits the viewing device communication signals at a frequency range within a radio frequency (RF) spectrum.

24. An apparatus according to claim 22, wherein the viewing device communication signals include information relating to one of shutter pulse rate, battery life, image brightness and speed of switching between the first and second operational modes for the first and second shutters.
