Start with what can

provide high quality streaming. In my book, that *usually* means a firewire connection (generally miniDV tape based camcorders) to a computer with a *very* high speed internet connection. It can also mean a HDMI or RBG (+ audio) or composite video connection to a Tricaster box that provides the streaming.

But just a camcorder? I don't think there is a way to do that.

Step 1: set a budget.
Step 2: see what fits.
Step 3: learn how that camcorder *might* provide video streaming (based on the video quality desired).
Step 4: revisit the budget.
