Note• During the multicast, if the connection bandwidth drops, the sending bandwidth will drop as well,lowering the resolution and/or the frame rate.• The quality of the multicast video and audio is affected by packet round trip time (RTT), the packet lossratio, and the number of packets re-sent. Terminals store approximately 1 second of data for resending,but if sending/receiving is delayed beyond this, the image may become corrupted. For details onnetwork design that takes into account issues such as round trip time and the packet loss ratio, contactyour dealer.Setting the SystemSetting Multicast1.
