By default, the video extenders mirror to multiple receivers but can be configured into a multipoint-to-multipoint configuration with multiple transmitters and many receivers. Multiple transmitters require a managed network switch with VLAN/IGMP support. Each VLAN acts as a separate HDMI over IP Channel on the network. When you use a single transmitter with many receivers, you should use IGMP to prevent other network devices from being flooded with multicast frames. Point-to-point is the most basic configuration of the video extender. To connect point-to-point, use an Ethernet cable to connect a transmitter directly to a receiver. You can use a switch that is not managed with a number of receivers, but you will only be able to mirror the HDMI input to the receivers.
