Problems solved by technology

However, the power requirements of the communication protocol will cause the battery to drain quickly, requiring frequent battery replacement
[0011] While the complexities associated with the synchronization required between the display and a single pair of 3D eyes can be efficiently handled, when multiple pairs of glasses are desired to view a display (such as a television), due to the need for each pair of glasses to simultaneously synchronize with the display operation, additional problems arise
However, the greater the number of glasses, the greater the bandwidth required to achieve it, which quickly makes such methods impractical

Embodiment Construction

[0049] figure 1 A television 2 is shown having a screen 4 showing alternating left and right views of scenes from a television program. The television comprises a transmitter 6 that propagates radio frequency signals represented by rays 8 and wavefronts 10 , and a control unit 12 in communication with the transmitter 6 . Control unit 12 contains a system clock (not shown). An observer 14 is located on the visual path to the screen 4 of the television 2 . Observer 14 wears stereoscopic (3D) shutter glasses 16 comprising left and right eyepieces 18 , 20 , a receiver 22 , and a controller 24 in communication with receiver 22 . Controller 24 also includes a clock (not shown). The left and right eyepieces 16 , 18 can be brought into a transparent state or an opaque state by a signal from the controller 24 .

[0050] The 3D glasses 16 allow the observer 14 to perceive a three-dimensional image on the screen 4 by allowing a left view through only the left eyepiece 18 and a right ...

Abstract

A stereoscopic viewing apparatus (16) is synchronized with a display (2). A signal(8) generated by or synchronised with the display (16) is transmitted. The signal (8) comprises a sequence of data packets (204), wherein each data packet (202a-e) in the sequence comprises an identifying portion of data. The stereoscopic viewing apparatus (16) receives a data packet (202b) from the sequence of data packets (204). A position of the data packet (202b) in the sequence of data packets (204)is identified using said identifying portion. Timing information related to the data packet (202b) is determined using said position. The timing information is used for synchronization of the stereoscopic viewing apparatus(16) with the display (2) and for determining when to activate a receiver(22) in the stereoscopic viewing apparatus (16) for receiving a subsequent packet.

Description

technical field [0001] The present invention relates generally to stereoscopic display systems, and in particular to robust power management systems and related methods for synchronized stereoscopic viewing devices with displays. Background technique [0002] It is known in the art to create a sense of viewing a three-dimensional image by providing two-dimensional images of left and right perspectives to left and right eyes, respectively. It is also known that moving a three-dimensional image can be achieved by providing a moving left and right perspective moving image. [0003] Various methods are known in the art to ensure that the left view is viewed by the left eye only and the right view by the right eye only, including complementary color filter glasses, linear or circular polarizing glasses, and shutter glasses. [0004] The limitations of complementary color filter eyewear, particularly their limited ability to provide true color images, are well recognized in the a...
