. System characteristic 5) Supports Dynamic IP

a. Can connect various internet media (LAN. WAN. x-DSL. coaxial cable and so forth) Whether it uses Permanent IP (fixed IP) or dynamic IP, it is perfect solution for sending and receiving Streaming Service. b. Can Broadcast where media station has dynamic IP. c. Remote control Media Station that has dynamic IP is possible 6) Supports Uni-casting and Multi-Casting a. The server can reception up to 500 units of clients at maximum (according to our own test). b. If more than 500 units of NM-Station are required with increasing numbers of local agents for broadcasting, they can be divided into more than 2 groups for operation. c. NM-Station can choose any server for access. d. NM- Station added to a group chooses the added server for access to share the load for one NM-4000 Server.
