stereoscopic viewing apparatus and display synchronization

摘要

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.

1. A method for synchronizing a stereoscopic viewing apparatus with a display, the method comprising:
transmitting a signal generated by or synchronised with the display comprising a sequence of data packets, wherein each data packet in the sequence comprises an identifying portion of data; the stereoscopic viewing apparatus receiving a data packet from the sequence of data packets; identifying a position of the data packet in the sequence of data packets using said identifying portion; determining timing information related to the data packet using said position; and using the timing information for synchronization of the stereoscopic viewing apparatus with the display and for determining when to activate a receiver in the stereoscopic viewing apparatus for receiving a subsequent packet.
