Ah-oh! tisk-tisk Phil ! Giving away DTS secrets! ;-)

Yes, a new DTS player is due out this summer, and yes, it will have a hard drive. When its info makes it to our site, I'll let you guys know.

I have got 4 of hese DTS 6AD's under my care up here, these things were installed and other than routine tweaking, they have never skipped a beat, which is more than can be said for the 4 CP500 in the same building. Steve's right, there are some clever wee touches in there, copying eq from channel to channel for example, that can save a heck of a lot of time, and result in a better overall eq. I notice the the CP650 software can do this too now though. It's a shame that the theatre can't get discs, they are intending to replace the DTS's with CP650 as soon as funds allow, because they advertise that they have digital sound in all theatres, which is true, but if your in one of the DTS theatres, there's a 99.9% chance that you are hearing analogue, which leaves the owners open to all sorts of flak, trades descriptions etc.

Oh Karen, you've REALLY screwed up now! Now you simply must tell us the one nagging question...

Will the new dts unit have enough hard drive space to hold at least TWO full length movies and a couple of trailer discs worth of trailer audio files so that double-ups in one auditorium do not require constant handling of the discs between every show?

(Ideally I would want 30gig or larger drives to store EVERYTHING in the average sized complex, with the option to upgrade to larger file storage for those big 30 plexes.)

Brad,

I believe that hard drive in the new player will be 20GB minimum. Where do you can found 10gb disk right now?

Bye

Antonio is right, it's really hard to find a hard drive that doesn't have the space to do what Brad suggests. But the question is "will the DTS system ALLOW you to do this?" Personally I don't see why not. Without the timecode the data would be useless anyway. Maybe the trailers will be the main thing residing on the hard drive? We'll see. Can't wait until the info is available. Let's get our hopes up now so we can complain later!

Splice Caching:
Throughout each reel of film, there are "bogus" blocks, which are in essence, extra blocks. With this extra data, we utilize the "dynamic load" feature (which can upgrade the DA20 portion of your processor), and the splice cache feature. It takes only several minutes to build up enough data to encompass 2 to 4 feet around the splice. We repeat the "several minute cycle" throughout the reel to ensure that it all gets read into memory.

yours for happy reel splices,
ken

"Excuse me while I whip this out..." Sorry, watching Blazing Saddles.

It would defeat the purpose of the "other two digital systems" to have to include a disc with each print to load a hard drive. Their claim to fame is they are self-contained on the film. A single system whereas the DTS is a double sound system. Both systems have respective advantages (and disadvantages).

So, Karen, where is my royalty check for suggesting the "DTS unit with built-in hard disk" concept in the first place? (check the film-tech archives--it's there!)

Seriously, though, that sounds like a great idea that should solve many (most?) of the complaints about the DTS hardware. I'm sure that many of us are looking forward to seeing it.

Mark,

I can't claim to have a lot of DTS-6ADs in my service but I don't seem to be having problems. Perhaps air in your part of the country doesn't allow for integrated analog/digital processors.

You two should be so lucky as to breath the quality of air that we have out here!

Bumping this up since the subject of high SR-D error rates came up in the SDDS thread. [Big Grin]

I remember sometime last fall, one of our SRD houses was constantly doing this 'blip' and reading F on the processor. Eventually, it got to the point where it was dropping out of digital all the time. Of course, this was the only thing that got anyone to notice. All we did was put in a new bulb inside the Cat. 700 reader and boom: it was reading 1's and 2's. It has been fine ever since.

Recently, our other SRD house is beginning to do this. We are gonna try the same thing again, but I was told we have to order the bulbs. Anyone ever try this?

Eventually the lamp degrades the reflector flacks and the fialment sags (just like the obslete excitor lamps for optical sound)
When this happens either the illumination is too uneven to grap the complete block or two low to get sufficient level
