Nice to see the new HD channels are on

I want my NASA-HD !

Fortunately, HDNET carried the Shuttle launch in HD. Awesome, and now, with this post, the newbie nag notice will go away.

Yeah that's true.. HDNet is still covering the Shuttle in HD.. I'm glad I'll have my 722 by then.. It's still in the mail.

People may hate the standard, but 1080ix1280 and 1440 are in the official standards in several places. Most obviously in satellite to home standards.
http://www.atsc.org/standards/a_81.pdf e.g see table 7.3
More important can be bit rate. Bit rate starved 1080x1920 can look awful.

And of course I don't think they added mpeg4, used in these new channels, to the atsc standards, yet.

1449 is a DBS COMPRESSION standard acceptable for use with one of the VIDEO STANDARDS, 1920x1080, 1280x720, 720x480.

1440 is not a video standard.

Clearly you didn't look at the official standard I pointed to. DirecTV and Dish may be the main parties who pushed it but the compression of 1920x1280 and 1920x1440 were accepted. True they must be converted to one of the output standards.

In fact I did. You didn't read what I said, which is the problem with most people who claim things that aren't true.

1440 is a COMPRESSION standard that is acceptable for the 1920x1080 VIDEO standard.

1440 is NOT A VIDEO STANDARD.

Never said it was but you had a typo in your earlier reply which is what I responded about. It is part of the ATSC standards as modified for DBS use.

But the point is that that dish is choicing to use this compression standard and is allowed to call the result HD. Even though many of us would rather they used the full 1920x1080i.

And many would rather they used 1920x1080i even though the PQ would be worse than ithe current 1440x1080i - all other parameters staying the same.
