Allow me to go a little off-topic...
Could anybody please tell me, what do we mean by 'Reference Quality Picture and Audio' ?
I have read this term in most of the BluRay disc reviews, but never came to understand what exactly it indicates technically !!
That is a very good question....
As,
just4kix said it is a standard for checking the quality of audio & video in av devices.
I just wanted to add a few more points here.
In simple terms, the disc is mastered or written with data (audio & video) of the highest standards which can be used to check, any available av devices those permit these formats (Dolby TrueHD or DTS-HD MA for audio and MPEG4 AVC or VC-1 for video). Now these formats are of the highest quality, so the disc can be checked for output whether one is enjoying the same as meant to be presented.
Now, it does not mean that all the blu-ray movies have the same reference quality a/v in them even if they have the highest formats. The transfer from the source to the disc is the most important aspect in recording the data. And this is why certain movies on blu-ray are said to be of reference quality.
Some movies of reference quality in my opinion (what I've watched):
300 (Video & Audio)
Behind Enemy Lines (Audio)
Black Hawk Down (Audio)
District 9 (Video)
Fight Club (Audio)
Master and Commander - The Far Side of the World (Video & Audio)
Saving Private Ryan (Video & Audio)
The Dark Knight (Audio)
The Godfather Collection The Coppola Restoration (Video)
The Matrix Collection (Audio)
There are many more of the reference quality movies on Blu-ray which I've come across but not watched them.
More light can be given on this topic by likewise/senior members here in HiFiVision.
