I'm setting up a conference and am planning on streaming one of the rooms. My basic hardware list is an HMC150(rent)into a blackmagic intensity pro to your software on a Win 7 pro I7 860 8 gig machine.
The goal is an HD stream to a few select sites for viewing gatherings - computer hooked up to a projector with sound at the other end (it is a sold out scientific conference with a general audience appeal)
I can change/swap out upgrade equipment as needed.
As described you can do that with Standard.
IP Camera support.
Soon Teradek Cube and LiveU support
Audio Inspector (mixing board like level control and sync adjust).
I don't think you'll need any of the above as described.
HD is supported in the standard version.
If your source were HDV you'd need to buy the plugin in the standard version but other HD sources such as HD webcams, HDMI, HD-SDI don't need it. Your camera is HDMI out so you don't need anything extra (beyond the bandwidth, the cpu, the viewer's bandwidth) to stream HD frame sizes and data rates.
