=46or broadcast networks, what we're seeing they like is that=20
unlike satellite transmissions, there is more flexibility=20
for them on IP (IPTv), which would let them lift compression=20
rates and pack more data into a stream.
But because most of them are primarily satellite=20
broadcasting houses, only starting to roll-out IPTv, they=20
need to maintain parity on both transmission media.
Whatever the case, 5Mbps would be too low. At 1080i, we have=20
a customer pushing HD channels at about 13Mbps a piece, give=20
or take.
