Profiles
The BD-ROM specification defines four profiles of Blu-ray players. All video-based profiles are required to have a full implementation of BD-J.
1.0
This is the basic profile that all current Blu-ray players (as of April 2007) are based on. Players based on this profile are only required to have 64 KB of application data area storage, which is typically used for bookmarks and other preference storage.[citation needed] Most players have more than the minimum required 64KB.[citation needed] After October 31, 2007 this profile will be superseded by profile 1.1 as the new minimum profile.
1.1 (mandatory November 2007)
What is typically referred to as "Profile 1.1" (but is more formally known as "Final Standard Profile") adds a secondary video decoder (typically used for picture in picture), secondary audio (typically used for interactive audio and commentary) and capability of supporting a minimum of 256MB of local storage (for storing audio/video and title updates). Compliance with this profile will be mandatory for player models introduced to the market after October 31, 2007[1], but existing products will be unaffected. No players compliant with this profile have been announced or released.
Some profile 1.0 players may be upgradeable via firmware update to profile 1.1 if they have the appropriate hardware, but no manufacturer has announced any such upgrade. When software authored with interactive features dependent on Profile 1.1 hardware capabilities are played on profile 1.0 players some features may not be available or may offer limited capability. Profile 1.0 players will still be able to play the main feature of the disc, however.
2.0 (BD-Live)
Profile 2, also known as BD-Live, adds network connectivity to the list of mandatory functions and increases mandatory local storage capability to 1 GB. No players have been announced as compatible with this profile. However it has been speculated that the PS3 could be upgradeable to this profile.
3 (audio only)
Profile 3 is meant for an audio-only player and does not require video decoding or BD-J.
