Abstract
A method for pairing of shutter glasses (411-414) with a remote control unit (RCU) (461-464, 272-273) for use with a display device (220, 230) configured to display a plurality of video streams by time interleaving the frames of the video streams and sending synchronization signal to shutter glasses. The method comprises the steps of: generating at least one synchronization signal (911, 912; 921, 922; 913, 923) for the shutter glasses (411-414); receiving an IR signal (331B) from the RCU (461-464, 272-273); comparing the temporal correspondence of the received IR signal (331B) with the generated at least one synchronization signal (911, 912; 921, 922; 913, 923); and in case a temporal correspondence is found, pairing the RCU (461-464, 272-273) with the shutter glasses (411-414) for which the correspondent synchronization signal (911, 912; 921, 922; 913, 923) was found.
