1. A non-transitory computer readable storage medium comprising instructions that cause a processor to pair shutter glasses with a remote control unit (RCU) for use with a display device configured to display a plurality of video streams by time interleaving the frames of the video streams and sending synchronization signal to the shutter glasses, by performing the following steps when such instructions are executed by the processor, the steps comprising:
generating at least one synchronization signal for the shutter glasses;
transmitting, by the RCU, an infrared (IR) signal for receipt by the display device, such that the IR signal passes through at least one lens of the shutter glasses prior to receipt of the IR signal by the display device, wherein the shutter glasses are separate from the RCU and operate, by alternating the at least one lens of the shutter glasses between a transparent state and an opaque state, according to the generated at least one synchronization signal;
receiving, by the display device, the IR signal from the RCU after the IR signal passes through the at least one lens of the shutter glasses;
comparing the temporal correspondence of the received IR signal with the generated at least one synchronization signal; and
in case a temporal correspondence is found, pairing the RCU with the shutter glasses for which the correspondent synchronization signal was found, wherein the shutter glasses for which the correspondent synchronization signal was found is a first shutter glasses of a plurality of shutter glasses, and wherein the RCU that is paired with the first shutter glasses is a first RCU of a plurality of RCUs, and wherein the correspondent synchronization signal is a first synchronization signal of the generated at least one synchronization signal, and wherein the steps further comprise:
transmitting, by a second RCU of the plurality of RCUs, a second IR signal for receipt by the display device, such that the IR signal passes through at least one lens of a second shutter glasses of the plurality of shutter glasses prior to receipt of the second IR signal by the display device, wherein the second shutter glasses operate, by alternating the at least one lens of the second shutter glasses between a transparent state and an opaque state, according to a second synchronization signal of the generated at least one synchronization signal;
receiving, by the display device, the second IR signal from the second RCU after the second IR signal passes having passed through the at least one lens of the second shutter glasses;
comparing the temporal correspondence of the received second IR signal with the generated at least one synchronization signal; and
pairing the second RCU with the second shutter glasses in response to temporal correspondence between the received second IR signal and the second synchronization signal.
