So who had a trick-play DVR available when TiVo filed its patent in the middle of 1998?
Here is the most notable electronic disk trick play video recorder that I happen to remember seeing in widespread use. Of course tape-based products, or even rapidly developed FILM products, were used from the 1950's. Ampex's Instant Replay device was commercially available by 1967. It's not digital.
Of course computers have been processing digital video for a
long time before Tivo existed. Tivo did not invent the DVR. Tivo did not invent trick play. Tivo did not invent a device to watch one program while viewing another. Any old VCR could allow that since they had their own tuners.
The only innovation I see in the Tivo patent is the indexing feature for
smooth trick play. This existed in my 501 and I enjoyed it's excellence for a few months before Dish eviscerated it from the firmware. No Dish receiver I have used since then, including my 501, my 625, my 722 nor my 612's, smoothly perform trick play. Hit one of the skip buttons? You really don't know how far forward or backward you're going to go, because Dish no longer has an index to do this accurately. There is not a doubt in
my mind that Dish has successfully designed around the Tivo patent.
And here we are arguing about whether Dish can use PID parsing, something that
every DTV tuner in creation has been doing for as long as there has been DTV. It's as though Tivo's claim #1 is "take one step forward", and Judge Folsom has suddenly found "taking one step forward" is Tivo IP. These argument about PID parsing are just that stupid. Note to moderators: I'm not calling Greg stupid. I'm thinking that about Judge Folsom, who must either be an idiot or on the take.
So, Greg, you have been aggressive in your defense of Tivo's and Judge Folsom's positions, crazy though they may seem
to me. Do you honestly believe Dish didn't succeed in their design-around? Do you think forcing Dish to recall receivers, or shut off all DVR functionality, is a remedy proportionate to the crime (which I believe is
accidental duplication of Tivo's IP)? Tivo's real contribution here is so narrow as to be evident to engineers on a moment's reflection. I would say the fine is more than adequate by itself. But telling Dish to destroy itself, in addition to this big fine, is not. That's my opinion.
