John,I left a message for Jeremy Lansman, he wasn't in. If he returns my call I'll report what I find.But I did talk to Fred at KUSI-TV who tells me that they broadcast a single upconverted NTSC digital signal in 720p.
Since you receive San Diego stations, you should be able to reconfirm your 704x480i30 at 16x9 claim for them.

Actually, I can think of two broadcasters in Anchorage Alaska (one is my customer, KYES-DT) that use 704x480 video. KYES-DT has two 704x480 streams. At one time, they had three, until I bitched about 4:3 video in a 16:9 frame. I have no connection to the other broadcaster; I couldn't even name the chief engineer. I can provide screen captures from TS_reader with the particulars, if you wish. Also, at least one broadcaster in Los Angeles (KXLA, I think) offered, the last time I checked, at least one 704x480 stream. In San Diego, KUSI-DT offers a badly-stretched 4:3 picture in 704x480. So, I have problems with your predicate. The three markets that I know of all provide 704x480 video. If you had said "no broadcaster in the Lansing, Michigan market uses 704x480", I wouldn't be able to dispute that. But currently -- at this very moment -- I know of three broadcasters that use 704x480 video. At KYES-DT, we've also tried 720x480, but that breaks a few receivers, and my customer is concerned about that. (We've done much testing in this area.) I read the entire post, John. It was incorrect, and your caveat didn't work. John Willkie, who tries (or tends to think he tries) to avoid all-encompassing statements when he only has a few data points. P.S. And, I'm assuming that "practical use" means more than 0 broadcasters use it. -----Mensaje original----- De: opendtv-bounce@xxxxxxxxxxxxx [mailto:opendtv-bounce@xxxxxxxxxxxxx] En nombre de John Shutt Enviado el: Thursday, November 08, 2007 10:12 AM Para: opendtv@xxxxxxxxxxxxx Asunto: [opendtv] Re: News: Nielsen Gives Fuzzy Picture of HDTV Penetration John, Please re-read what I wrote. 704x480i in 16:9 is a valid ATSC format (yes I know table 3 was not adopted by the FCC) but it is not currently used by a single broadcaster in the United States. I said it would never be used. I said that perhaps 480p 16:9 would be used, but 480p is ED, not SD. I said that the only 16:9 native format IN PRACTICAL USE will be HD content. That includes 720p60, 1080i30, 1080p24, and 1080p30. For cable, that could also include 1080p60 using advanced codecs. Thank you for reading the entire post, not just what jumps out at you as wrong.
