I remember seeing a video back before blu-ray/HD-DVD came out from someone at Dolby saying that Dolby Digital was as transparent as the master and that they did not see a need for higher bit rates. I remember that just after HD-DVD came out Dolby Digital Pus was being mostly used for HD-DVD titles. A number of Blu-rays had some uncompressed PCM tracks, some titles where using the old lossy Dolby Digital and as time went on more and more titles had Dolby True HD. At some point the studios moved away from Dolby True HD and adobted DTS-HD Master Audio for Blu-ray releases. I do not have any links to the video but I distinctly remember feeling that while Dolby Digital Plus was a definant improvement over the original Dolby Digital. But I still back then prefered DTS to even Dolby Digital plus even though I had many HD-DVD titles that had Dolby Digital Plus as the primary audio track. Back then when Blu-ray came out I decided that after the first few titles that I would no longer purchase any Blu-ray with Dolby Digital and that may have been around the time that Toshiba pulled the plug on HD-DVD right before CES that year.
DTS got lucky with Blu-ray 5.1/7.1. Looks like that luck has run out with object-based audio.
Dolby was first to market with there lossy 5.1 and DTS came along and made a better lossy codex IMHO. I have over the year's had many components using Dolby technology and they have led the way and have been leading the way for most of that time. So after that we know that Dolby beat DTS to market and put out there lossless format first again but even with a problem or two DTS still was able to come out after with there lossless codex. We can argue about what caused Dolby to loose the support of the most studios but the fact is more titles where released on Blu-ray in DTS's DTS-HD Master Audio and so far more 4K UHD discs have DTS tracks than Dolby tracks. Now DTS is having some kind of issue getting out new firmware and the intergration of DTS-X seems to be an issue. At this same time Dolby doesn't seem to be having any issues with there Dolby Atmos even though once again I believe the where first to market again. I do love the DTS company but I have grown up with Dolby and while I did have issues with the Dolby Digital product and got to a point where I avoided it. I can say that now that we have DTS-HD Master Audio and Dolby True HD and that they both sound great. For myself I can say that I can purchase a movie and as long as the audio track is ether one of those I can be very happy with ether one. I have been a DTS supporter but at the same time I do not hate Dolby, I just did not care for Dolby Digital. If DTS-X fails and goes away then that will be on DTS for failing because in the home video market moving forward beyond DVD, DTS achieved overtaking Dolby in Blu-ray's and 4K UHD discs. It is hard to say if DTS will continue with just there lossless codex for Blu-ray and 4K but if Dolby's Atmos gets more support from the studios that may pave the way for more Dolby True HD tracks as well. My upgrade plan currently includes both Atmos and X decoding as well as full 4K path from source to display. All I need is a new receiver with 4K switching and HDCP 2.2 and I will be in good shape. So far I am leaning towards a Marantz reciever but that will be sometime next year and I might even get Auro 3D if it is available just to have the capability and just incase a 4K UHD title becomes available overseas and the domestic version only has standard lossless, depending on the title in question.
Dolby may still have total dominance of the market in general but DTS came around and effectively took the HD blu-ray market from them. Who is to say if another company could not come around and challange Dolby again? Dolby could very well take advantage of DTS's screw up and take back the blu-ray market. Ether way I just want to see lossless tracks included as IMHO they are the best way to reproduce the audio tracks for the movies we love. I can totally live with DTS-HD Master Audio or Dolby True HD and be more than happy with ether one. If I ever can come up with a link to the interview in question I will post it.
I just want the best presentation when watching movies at home and some day my goal is to have a 4K UHD projector with a 120" - 160" screen. It seems like a waste of money to upgrade the audio side just to go back to Dolby Digital and or Dolby Digital Plus with things moving towards a internet based digital delivery system. Trust me the studios will be alienating a large number of customers that not only think 480p DVD is good enough but those who do not have computers, do not have internet and many that still do not subscribe to cable.
"Similar claims come from Dolby Labs, namely that when Dolby Digital is encoded at the maximum 640 kbits/s defined by this standard, it is capable of achieving similar audio perceptual transparency results, in that the listener would not be able to distinguish between the original un-coded source and the output from a coded soundtrack. Yet, in real life implementation, things are somewhat different..."
"DVD-video format limits Dolby Digital sound tracks to a bit rate of 448 kbits/s. At this reduced bit rate, perceptual audio transparency is lost. On some DVD releases, this is even further limited to a bit rate of 384 kbits/s. In either case however, these bit rates are higher than that used in moviehouse applications."
I do not care for how perceptual coding works and even though I was a big fan of DTS over Dolby Digital. Any DTS DVD that I have not replaced with a Blu-ray version at this time is in no way safe from being replaced. Lossy DTS is in no way as good as the lossless Dolby True HD or DTS-HD Master Audio or even uncompressed PCM. I still have a number of DVD's that have not been upgraded because of the limitation of my finances. But sooner or later many of those titles will be ether upgraded to 1080p Blu-ray or 4K UHD Blu-ray with lossless audio tracks. I also do not care for mp3 or wma and am not a fan of digital downloaded music! Doesn't matter if I am listening to that music on my main home theater or my pc that uses a 5.1 reciever and a 2.1 speaker configuration or the former 2.1 pc speaker configuration. I prefer having the CD and or even the LP vs purchasing an inferior digital download that relies on a hard drive that has a short life span. And if you loose your internet try streaming music or movies or re downloading anything if your hard drive dies with no internet, sorry not me.
