These days, i2CAT is sending live contents using Videolan (4Mbps) and DVTS (30Mbps) from Barcelona (Spain) . They are different because Videolan content is the final program and the DVTS is a fixed camera. Today (Friday), we transmit live content : from 4:30 p.m. CET/11:30 a.m. EST/10:30 a.m CST to 6:30 p.m. CET/13:30 a.m. EST/12:30 a.m CST
Videolan: 233.50.241.2 port 1234 DVTS: 233.50.241.1 port 8000.
