(reproduced without permission from page 64 of Video, September issue): "Toshiba has a major innovation in its CZ-2697 monitor/receiver, which essentially uses digital "non-interlace" technology to double the number of visible lines in the NTSC standard. The result is not more picture information, but more lines to convey the same picture information. Reportedly, the picture looks better. Availability and price were not known at presstime. . ." It is not obvious from this fairly braindamaged press report whether it's done by saving entire frames or just single scan lines. Also, I'd guess it's done with the ITT chip set, which contains (I think) 3 (RG&B) 6 bit flash converters run at about 10.5 Mhz (I wonder if they can be pushed to 14.14 Mhz?).

I happen to know some of the team members who developed the chip set in ITT Intermetal, Freiburg West Germany. I have data sheeteets on the chips. They were originally developed for the European TV standard using 625 line 50Hz PAL color. NTSC and other versions followed. The flash converters run at 4 times color burst which is 14.3 MHz for NTSC and 17.7MHz for PAL. Mike Gingell ....decvax!mcnc!ecsvax!mjg
