I'm not saying you need the whole 19mbps (though, remember here, we are not talking about "Additional Carriage"; we are talking about *being the only way people can see that game* -- and my example was the Super Bowl).. but unless MPEG algorithms have gotten *much* better than I'm aware of, 5mb/s is probably not enough for the Super Bowl. And you'd really be better off with some FEC, too, even if it costs you a couple frames extra delay.
For broadcast networks, what we're seeing they like is that unlike satellite transmissions, there is more flexibility for them on IP (IPTv), which would let them lift compression rates and pack more data into a stream. But because most of them are primarily satellite broadcasting houses, only starting to roll-out IPTv, they need to maintain parity on both transmission media. Whatever the case, 5Mbps would be too low. At 1080i, we have a customer pushing HD channels at about 13Mbps a piece, give or take. Mark.
