This set was late 80's 4:3 CRT. Only saw one before it disappeared. I'd like to track down the model if someone can help.

QUOTE: Do you get any remuneration for any of the listed patents on your page?


Aside for a $300 reward per patent, all I got was bragging rights. No royalties, but I wouldn't know how to go about marketing them and getting such.

As for bragging rights, I had a list of my patents on my resume. Thus showing that i've invented stuff, and should be able to do that again at new jobs.

QUOTE: Philips could have used more exotic patents in the late 80s when they briefly launched a progressive scan TV that had no motion compensation. I stared at it in the store, its picture was a soft blur, the product was quickly withdrawn.


Figures, Philips management were idiots (worked there after RCA). That TV likely had a field delay, and building a motion detection and correction system would have been reasonably easy (one of my patents). You'd also meed a good chroma/luma separation method too.

I just sought more info regarding this TV on videokarma. A tech in New Orleans said he'd encountered them and Philips were soon offering free exchange for these bloopers Smile

So yes, there must have been good patents for deinterlacing at that time but Philips didn't want to pay up. One good deinterlacer I saw at that time was a Pro wunderbox from Faroudja Labs, but it might have cost $10k. I saw him running it at a convention booth, he was feeding a movie from a Pro component Betacam player (no problem with Y/C separation) through his processor to projection screen. The picture, though large, was sharp and looked like film with no annoying scan lines. Yves Faroudja himself was manning the display so I got to meet this amazing scientist!

I'd forgotten many early HD TVs simply repeated fields to avoid temporal blur Sad

But since the videokarma poster described this 80's Philips as "very soft, almost unfocused", matching my experience, leading me to suspect Philips went right ahead and blended both fields sans processing Sad

Thinking back again about Faroudja's landmark 1980s demo, I'm now suspecting that he had that movie scanned on a hopped-up telecine that was wired for Component source signal which he preserved on that Pro Betacam, all the better for his wunderbox to go to work on deinterlacing~~oops, now thinking further, his interlaced source would have been PsF fixing usual intraframe motion blur!

The projected picture was like 10 or 12'! and looked wunderbar!
