Note 1: The PD4D does not support IGMP, therefore static multicast routing needs to be configured on any switches to allow the multicast to flow to the PD4D
Note 2: The PD4D sends periodic gratuitous ARP, this may disturb unicast IP video playout on a Windows PC
Note 3: Each multicast IP stream should be on a separate multicast IP address
