[opendtv] Re: Food for thought

Bert,
I give up. You have no data suggesting what MPEG-2 HD data rate would have been acceptable to the BBC, nor do you have any data suggesting what MPEG-4 HD data rate would equal MPEG-2 image impairment.
Again, you don't know if the BBC would have deemed 40 Mbps, displacing 9 or 10 SD channels, to be the minimum required for MPEG-2 HD, since they didn't even test MPEG-2 HD. How you can jump to the conclusion that MPEG-2 and MPEG-4 are essentially equal in bitrate requirements when use in HD is beyond me, beyond logic, and not supported by any data.

"More efficient" can mean anything you like. The fact that you need to
displace 3 to 4 SDTV programs to make room for one H.264 program is a
real tough elephant to miss in the room, John.
