This was posted earlier in this thread from TWC:
"Time Warner has chosen not to carry WXIX-DT on its digital tier because all programming on WXIX-DT is distributed in the 480p (both 4:3 and 16:9) format. TWC does not consider 480p an HD format and therefore is not willing to give up channel space for a standard definition digital channel."
This seems to say that WXIX is sending out 480p and not 1080i. Am I missing something?
Yep, you are missing something
No, it is not considered HD unless the programming is actually produced(or transferred from film), and distributed in HD.
WXIX-DT is sending 1080i (unless something has changed recently, but it doesn't look like it from what I can tell) -- but NONE of the programming that airs on WXIX-DT is native HD (although at some point in their past I wouldn't be surprised if they aired some HD test loops/etc) -- it is all UPCONVERTED from its native resolution to 1080i by WXIX.
The Programming they air would have to be produced (or transferred from film) in HD, and distrubuted in HD (such as Fox HD will be) before they can actually send us HD. WKRC (local 12) news for example is sent as 1080i by WKRC-DT, but it isn't HD -- it is upconverted at the station from its native source(4x3 NTSC video - which is pretty close to 480i
SD). "CSI:Miami" on the other hand, is shot on Film and transferred to HD, and distributed in 1080i HD by CBS, and you "truly see" native HD when WKRC-DT airs it. If you watch PBS HD channel on WCVN-DT/KET4 or WCET-DT -- Some of that programming is HD, but much of it is Widescreen SD that is upconverted to 1080i at the network level and sent as 1080i by WCET-DT, or "sideconverted" to 720p in the case of WCVN-DT, as they choose to send PBS HD at 720p instead of 1080i.
As I mentioned before -- We often call "Fox widescreen" 480p, because that is what it is from the stations that are(most Fox affilates which were doing Fox Widescreen before the Fox HD upgrades at the affiliates began DID send 480p 16x9 ATSC format, although some sent 1080i, some sent 720p, some sent 480i 16x9) actually sending 480p ATSC format -- But, the programming is actually distrubuted by Fox as 480i anamorphic(another way of saying that which some think is more correct would be "16x9 NTSC video"), and the stations that are actually sending 480p deinterlace it(and I think 3:2 pulldown is added at the affiliate as well, or is "supposed to be" at least so your display doesn't necessarily have to support it) and send it as 480p ... In other words, "somewhat"(more or less) like a progressive scan DVD player.
Fox Widescreen(Which is also referred to as ED or "enhanced definition" but could actually also be called SD widescreen IMO) is, PQ wise, pretty much on par with "anamoprphic" Widescreen DVD, No matter WHICH ATSC format the affiliate is sending (480i 16x9, 480p 16x9, 720p, 1080i). Any differences in quality you would see between stations sending any of those formats would mostly have to do with either the upconversion equipment at the station(depending upon what format they are sending -- If they are sending 480i/p then they aren't upconverting the programming from its native resolution of course), or the viewer's equipment and how well it upconverts to the native scan rate your display is using.(1080i, 720p).
In other words, If you have a DVD player that has a scaler that outputs at 1080i, basically speaking you would be doing the same thing with DVD (which is "natively" 480i 4x3 NTSC video, or 16x9 NTSC video(latter also is more commonly called a "anamoprhic" DVD)as WXIX-DT is doing with Fox Widescreen, any other Fox programming presently, or WXIX local syndicated programming ....
What we are talking about here when we say WXIX is sending 1080i, is the acutal ATSC format they are sending us, not the "native" resolution of the programming or what Fox is sending THEM with Fox widescreen, whereas, The latter is what TW and WXIX's CE is reffering to. (I think they are calling it 480p for "short" rather than going into deinterlacing and upconverting and the like) ....
Hope that makes some sense ....
Update : Oh, btw, I meant to add the following link in my last post to this thread which has loads of great info on FOX HD, the upgrades to Fox's distribution system for HD, and info on the HD splicer upgrades for the affiliates :http://www.avsforum.com/avs-vb/showt...03#post3304603
