We would consider doing non SFN and non diversity and believe even then we would have an acceptable offering at decent bit rates. But we don't have to do that. We can do both diversity broadcast and reception. They will do that in Japan even with cell phones and presumably a better modulation. Then there is DMB-T which claims to be far better than DVB-T or ISDB-T for mobile. Our little test in NYC with DVB-T is not what would be deployed today. You cannot judge what a network would look like based on this test we did. A bit of extrapolation is in order. But for what it was it is amazing. We know that we can build such a network at over 18 Mbps that will work flawlessly mobile or fixed. >We also remember the hype from the Far East with their SFN and TV on busses: >they had to go to much higher powers >to make it work, if I recall right.

The market should determine the resolution of the video. That is the way the law reads and that is the way it will play out.
