Apple seeded the iTunes 8.3 to Developers  earlier this week. Some folks over at AppleInsider & MacRumors Found for intresting hints in the reference with in the iTunes upgrade- the reference notes  ”CD, DVD, Blu-ray Disc, and music and video-related data from Gracenote.“

Apple on Tuesday equipped iPhone developers with a beta of iTunes 8.2 that appears to add full support for Gracenote’s video platform, which includes components for organizing, searching and managing both DVD and Blu-ray optical discs.

Hints to this end were noticed in the credits roll of the new jukebox software by both a MacRumors forum member and AppleInsider reader David. The specific reference reads, “CD, DVD, Blu-ray Disc, and music and video-related data from Gracenote.”

The current version of iTunes includes similar credits but without mention of DVD and Blu-ray, leading to speculation that iTunes 8.2 will ship with software support for recognizing and reading Blu-ray discs.

Once called Compact Disc Data Base (or CDDB), Gracenote is a firm that maintains and licenses the largest Internet-accessible database containing information about the contents of audio discs and digital music files. Applications like iTunes tap into the CDDB database to easily provide users with album names, song titles, and other information about their audio CDs, which don’t contain such descriptive information by default. 

“iTunes connects to this database to look up information about the CDs you own so you can easily select which songs to listen to and sort and view your music library,” Apple explains in a support document on its website dated August 2004.
