View Full Version : Dts - Omg
Finally got a chance to wire up my Crimbo pressie over the weekend (Christmas Tree had to come down first) - a shiney new DTS (Dolby Theatre Sound) home cinema amp. O.M.G. I didn.t think there'd be that much of a difference between prologic & 5.1/DTS. I'm never leaving the sofa again. Need to buy a detached house now though. Just found out next door is expecting.
Difference between DPL and 5.1 = HUGE!!
Good to hear you have been blown away - also, call me pedantic, but DTS = Digital Theater System.
Enjoy!

When you go to the movies, you may be wondering what all those letters mean associated with a film. In addition to ratings (G, PG, PG-13, R, NC-17), there are the sound systems with their own monikers appearing before the movie. Two of the most famous are DTS and THX. But did you know that these are not competing sound systems? That's correct -- DTS and THX often work together in the world's finest theaters to deliver the very best digital sound experience possible.
Simply put, a theater's digital sound system is made up of two areas. The first (Area 1)consists mainly of projection equipment and actually "reads" the soundtrack of the film, decodes it, and processes it. The signal that results is fed to the second area (Area 2), the theater's amplification and loudspeaker system.
DTS technology is utilized in Area 1, where cinema sound processors convert the analog and digital sound information through CD-rom into top-quality audio. THX is involved in Area 2, especially for loudspeaker placement and the acoustics of the theater auditorium. To obtain THX certification, a theater must comply with their standards and also make use of equipment from THX-approved manufacturers. All DTS equipment is approved for usage in a THX certified theater.
Both DTS and THX can exist on their own, but often do go together. When they do, the result is digital sound that is nearly identical to what the filmmaker intended. And for you, the moviegoer, that means a sonic movie going experience to remember.
quicky question:
what about Sony's SDDS? what is it exactly? How does it compare to the other two and can we get it in home cinema setups yet???
Tut, tut, zerocool. Stealing other people's hard work! http://www.dtsonline.com/thx.html

Sony are "distancing themselves" from THX and don't seem that keen on DTS-ES either, so this is their own attempt...
any good?
any techy specs somewhere to read???
SDDS is simply adding more speakers to a system/theater to make the sound more fuller/together. They used SDDS in a film I went to see recently. (can't remember which)
In a theater showing a film with SDDS they might add 2 further speakers to the front making a center speaker and 4 main speakers. They also add surround speakers at the sides and back so you could end up having a total of around 10 speakers plus a subwoofer or two :D

SDDS is a 7.1 system developed by Sony for cinema use (no surprise that they aren't that interested in DTS then).
According to Sony, they have no plans to make SDDS available for home cinema use.
For more info, go to www.sdds.com
thanks for the link:) very interesting

Also :
THX is a lucas company, and you need to pay them for the use of the moniker.
This is why you wont see yamaha THX certified amps (etc) because they refuse to pay THX and they say their own system is better.
DTS is used in cinemas much more than DD because its cheaper and better.
DTS uses seperate CD rom type things synced to the film to store the audio.
DD uses information on the reels in between the sprokets. This is expensive to read and probe to scratches/dropouts.
DTS uses 2 bitrates.
So does DD ( R1 disks get a higher bitrate than uk I think).
DTS higer bit rate is accepted as better than DD.
DTS lower bit rate ( 720kbps?) is roughly equal to DD ( 384kpbs?)
I say roughly because DD compression is superiour and DTS have been caught cheeting with their encoders ( adding 3db - humans tend to hear louder as better).
nice info, i just got Rush Hour 2 dvd and it is in DTS-ES 6.1 so whats that all about then?
in cinemas b4 the film starts how come there is never a DTS test track played? its always Dolby Digital, so i thought that the films were shown in Dolby Digital and not DTS...

Dts has two trailers for cinema, the Yamaha Piano 'Sonic Landscape' (to give it its official dts title), and the very poor and very old flying cd with words flying all over the place, accompanied by, as you mentioned, smashing glass!
Dolby have 7 trailers and the dvd containing these can be bought from http://www.dolby.com Go to the online store (ensuring you select Euro Order Form), and its there for your delectation. It's short, but to show off your system, the Train trailer wins every time :-)
SDDS is good, but so it should be with 8 channels of sound-this smacks of Sony just trying to be the pretentious show off schoolkid! Would you really want 5 speakers and a sub surrounding the tv?! Overkill here we go!
Personally, the custom THX trailers for Toy Story 1&2, Terminator 2 on dvd, and the ones for Waynes World at the flicks all those years ago were absolute quality! Anyone remember this?

Last one i saw was JP3. Shockingly good, but you know its only going to be a one off. Projectionists are lazy and don't really care about quality. My friends sister is the manager at UCI in Cardiff, and says most of the projectionists just do their job and go home! All the prints come with the neccesary soundtrack options, but the guy in the booth just won't make the effort. Shame...

Apologies for nit-picking but...
DTS does have two rates, but these are 1509kbps (full-rate) and 754.5kbps (half-rate). All new DTS discs (save a few Jap ones) will have a half-rate track because that's the current accepted standard. Basically, there isn't room for a full-rate DTS track AND a DD5.1 equivalent, so they always use the economy version of the format these days (even Super-Bit titles).
DD5.1 has two rates also, 448kbps and 384kbps. While it's true that R1 discs use the full-rate version as standard, the trend of using the cut-rate version for R2's has died down dramatically of late. The majority of new releases will have a proper 448kbps track and only a few multi-lingual back-catalogue releases will use the inferior version.
I say roughly because DD compression is superiour and DTS have been caught cheeting with their encoders ( adding 3db - humans tend to hear louder as better).
There's more to it than that though. Don't forget that DD5.1 tracks are designed to down-mix into plain 2-channel affairs for TV playback. That's why so many R1 discs offer an additional Surround track in order to avoid this compromise.
DTS tracks DO get special treatment in terms of directional effects and sub usage, but that's not really 'cheating' or in any way unfair. There's nothing to stop the DD producers from boosting certain elements of their offerings or making the soundstage more lively. In fairness to Dolby, their work is often much warmer and subtle, providing terrific ambience. The only things that people seem to remember are the bass usage and active/sweeping effects though and by using that criteria alone, DTS will always come out on top.
