I would agree that using E-VSB for video is a brutal trade. But using E-VSB for backup audio would pull less than 150 kbps from the 19.3 Mbps (it could probably be made even less) and would allow marginal viewers to continue with programming they'd otherwise have to dump.

E-VSB is a really brutal trade of primary stream data rate, just to improve C/N threshold on a secondary stream. ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
