If no one else sends the memos (3) to you, I can repost them but not e-mail them. Jim Winer ..!lzfme!jwi I believe in absolute freedom of the press. Pax Probiscus! Please do not email anything that requires a response outside AT&T. I receive email okay, but can rarely send a reply sucessfully. The opinions expressed here are not necessarily Those persons who advocate censorship offend my religion. -----------------------end end end--------------------------------------------- >Charles A.

This is a plea for contributions which could convince the HDTV standards community to adopt square pixels for 1125-line HDTV. The current proposal calls for pixels that are 4% narrower than they are high. This fact is of little significance for traditional television but I believe it would severely limit the appeal of the standard to commercial, industrial, scientific, and medical applications, and in particular to computer graphics. ----- HDTV STANDARDIZATION -- NAMES AND ADDRESSES SMPTE COMMITTEES Richard J.
