There was a Q/A session about the new splicer/IRD system and the following caught my eye:23) Can I have more than one HD service through the splicer?
A. While the splicer is capable of passing multiple program streams, the ATSC bit rate of 19.39Mb/s cannot support more than one HD program.
Someone needs to tell the idiot managers of stations that forced their engineering staff to do just that, resulting in both HD 720p streams to look like crap.
And obviously the answer is incorrect. You could place 10 HD streams into that transport streams, but you wouldn't able to see much
This gets into the argument as to what constitutes HD. Is it just the fact that it is 1280x720 or 1920x1080, or is there a level of image quality to go along with it.
