OT: Play regular MPEG on a DVD Player?

[Joerg]

Yeah, like I said, we got the Tascam CDSSR-1, but then the old product
idea went thinking....

The only hits I did see were for TI DSP software, so I guess that no
one is doing this in chip form, then.

Back to the drawing board...

Ok, but don't saddle the wrong horse there. I don't think it would be
possible to recoup the NRE of a MP3 encoder chip design. When I was
young everybody recorded stuff. Nowadays the kids just download iPod
tunes and the only ones left to record anything are secret services,
rock bands and churches. Digital voice recorders don't really count
because they use rock-bottom quality sound.

I'd just take a $5-$10 DSP and be done with it WRT hardware. The
remained is "just software"

I coasted most of the way from Springerville, AZ, down the mountain to
Socorro, NM, one time in the middle of the night... seems gas stations
in Springerville closed at 9PM :-(

I did that one night into Wilkes Barre PA, except that it was the
fan belt that let go. The good news was that it was -10F. The bad
news was that it was -10F at 4:00AM.

Only time I ever threw a belt was westbound from Austin, TX, heading
to Phoenix, after dropping daughter #2 off at Baylor in Waco... in my
'83 280ZX... A/C belt... made a helluva noise and dented the
splash-guard :-( but didn't sever the oil cooler tubes ;-)

Found a parts house in Fredericksburg, TX, with the right belt
sizes... bought a complete set of belts, dropped the car off at a gas
station (they did repairs in those days), then went and had a
marvelous meal at a German restaurant ;-)

Fredericksburg, TX, was settled by German immigrants, and has many
German restaurants and antique and hand-made furniture places... nice
place to stop.

And the guys at the gas station didn't say "Ve could haff told ya dat
dis wud happen wid a Japanees cah"?

Texans are red necks, _irrespective_ of ancestry ;-)

That's what some Germans say of me, too ...

What part of "you're nuts" don't you get?

Oh, maybe, the part where you can't back it up. James Arthur has
displayed it all rather nicely. It is much better work than i could
have done. Lots of links, and everything he has posted checks out.

 

[JosephKK]

Ok, here is my take on this...

As I understand it, there are like, 24 different companies here in
California that are working on developing an electric car, with Tesla
just being the one that gets the media attention. So, what if the
government gave each of them a billion dollars (or, say, the top 10)
and then said - "The first one to produce 10,000 viable cars that
meets this specification gets two billion dollars!" and let them go. I
am sure that there are companies in Mass. and Michigan that could get
in on the competition.

Heck, I would love to get in on something like that. I have two
friends who are car designers, and with the guys on this newsgroup, we
could hack out the power electronics in a few weeks. We would create
millions of jobs, these new companies could then buy the car factories
GM and Ford are closing for pennies on the dollar, and the country
would see a new revival of entreupenarial spirit!

Kind of like the DARPA desert challenge. Producing more qualifying
designs in two years that is typically achieved in ten years the usual
way.

Ok, but don't saddle the wrong horse there. I don't think it would be
possible to recoup the NRE of a MP3 encoder chip design. When I was
young everybody recorded stuff. Nowadays the kids just download iPod
tunes and the only ones left to record anything are secret services,
rock bands and churches. Digital voice recorders don't really count
because they use rock-bottom quality sound.

I'd just take a $5-$10 DSP and be done with it WRT hardware. The
remained is "just software"

Yeah, that 'just software' can drive you bananas! I am presently
trying to do a couple of 'simple' things on a Pic, and can't get
anything to work. I so prefer hardware!

That is most of the show. There is a bit more, the system describes
the decoder behavior in excruciating detail. Encoders though are
required to produce output streams that are correctly decoded, and
other than that, can be arbitrarily complex. Thus specialty encoders
that reproduce a more accurate signal on the standard decoder are very
expensive.
BTW both JPEG images and MPEG video is specified similarly.

I had changed the alternator the night before we were leaving for
the mid west for Christmas and evidently I overtightened the belt.
As I usually do, I left all the tools in the trunk (sockets still
on drives) so all I had to do was find a all-night gas station that
also did repairs. I bought a belt and changed it myself by the
pumps. Didn't help the cold though.

Wilkes Barre, PA. has none of that. In fact, it has *nothing*.

Look at the bright side: If you forget the WDT or something and it runs
into the wall there is no smoke and you don't need to swap out a fried
48-TQFP.

Good point! but it just drives me nuts when I am trying to step
through the program, and it just suddenly jumps back to the beginning.
I don't know if there is a WDT that is getting triggered, or some
other fault in there... :-(

Or, as has happened, after three weeks of pulling your hair out the
manufacturer pops an errata sheet along the lines of "Whoops, sorry
'bout that".

Oh, I had that a few years back working on a small Moto MCU. I had
one pin that I was using to activate a relay, and it never worked.
Finally, after about a week of head-wall-bashing, I contacted Moto and
they said "Well, did you look in the Errata?" Seems that pin only
worked as input only. Swapped a couple of pins around, and I was
fine.
