multiple hosts are sending traffic to same vlan

hi All,

two hosts are connected 3560 and sending multicast traffic.

1. both hosts send traffic to same multicast group / udp port (e.g.
239.1.1.1:150)
    which traffic flow will be received by far away multicast client (when
client is subscribed to 239.1.1.1:150)
2. is there anyway ... so second host does not start multicasting if HOST1
is active for same group address
