I've been doing a lot of research on high definition formats lately and the majority of what I can find on the internet is marketing based.
One place in particular I found "marketing based" information relating to XDCAM HD. It stated that HDV has been agreed on as not a good enough recording format for broadcast. XDCAM HD being based on similar mpeg technology with higher bit rates does make it into broadcast acceptance levels.
It's all totally understandable until I find that XDCAM HD can record at 18, 25 and 35Mbps. 18 of course being lower than HDV's 25.
Does anyone know anything about this, or where I could perhaps find more? I can't seem to find anything else similar.
