Wzap has asked me to provide server resource specs for a previous broadcast due to the fact that apparently this is the #1 issue for most broadcast producers.
hope this helps:
Processor : 64 bit Celeron D
1 GB Ram
1300GB (4mbps) Bandwidth
160 GB Sata
Broadcasted at 640x480, 29.97 500 kbps / had about 300 viewers (maybe more) for 5 hours encoded h.264
Virtual server provided by CariNet. No problems with stream.
