Blu-ray 3D also specifically calls for PlayStation 3 consoles to have full BD 3D content playback. According to CDRinfo:  “Additionally, the specification supports playback of 2D discs in forthcoming 3D players and can enable 2D playback of Blu-ray 3D discs on the large installed base of Blu-ray Disc players currently in homes around the world.”

“The Blu-ray 3D specification calls for encoding 3D video using the Multiview Video Coding (MVC) codec, an extension to the ITU-T H.264 Advanced Video Coding (AVC) codec currently supported by all Blu-ray Disc players. MPEG4-MVC compresses both left and right eye views with a typical 50% overhead compared to equivalent 2D content, and can provide full 1080p resolution backward compatibility with current 2D Blu-ray Disc players,” CDRinfo adds.

The specification also incorporates enhanced graphic features for 3D. These features provide a new experience for users, enabling navigation using 3D graphic menus and displaying 3D subtitles positioned in 3D video.

With Blu-ray the expectations of home cinema enthusiasts have been raised and on-line reviewers are becoming more and more eagle eyed and knowledgeable about the format and passionate about the titles they are reviewing.

For the real enthusiast, the purchase of a Blu-ray disc could be the fourth time they have purchased a title.  Blu-ray was preceded by VHS, Laserdisc and DVD with each new format promising the best picture and sound quality.

Sometimes, people’s expectations are unrealistic, but in most instances there is no reason why a properly mastered title should not equal the cinema experience in your home.

With the advent of DVD & Blu-ray review websites and forums, titles being released today are given almost an additional QC by the reviewer.

These things are regularly picked up in the reviews:

• The presence of film grain and the director’s intent
• DNR (Digital Noise Reduction), EE (Edge Enhancement) and the battle to educate the “Playstation 3″ generation that films in high definition shouldn’t always look like High Definition Sport shot on Video.
• The use of screen grabs to highlight issues and whether the saving of the image to a ‘lossy’ format like JPEG skews the validity of the image.
• The use of screen grabs in general to highlight an issue which may or may not occur for just 1/24th of a second.
