What is Multicast?¶
The multicast function allows you to transmit the screen contents including sound from one device via a paired transmitter to multiple displays simultaneously.
Extensive Touch-Back Support with QuattroPod USB and Multicast
Demonstration: Extensive Touch-Back Support with QuattroPod USB and Multicast
Multiple participants have the option to transmit their screen contents to multiple displays at the push of a button. However, only one participant can perform this function at a time.
Note
