About Blu ray

Blu-ray Profiles

  • Profile 1 Version 1.0 — The basic Blu-ray profile. All Blu-ray players released into this profile before November 1, 2007.
  • Profile 1 Version 1.1 — Adds secondary audio and video decoders for BonusView (picture-in-picture) support. This can be used for things like director's commentary. The player displays the movie in its original, full-screen form while also playing video commentary from the film director on a smaller, inset screen. In this profile, players must include 256MB of local storage for audio/video and title updates. This can be built into the player or available through a removable memory card or USB drive.
  • Profile 2.0 (also known as BD-Live) — includes all of the functions of Profile 1 Version 1.1, but increases local storage capacity to 1GB. Players in this profile must also include an Internet connection. It allows you to connect the player directly to the Internet to access bonus material available on some Blu-ray movies. Some movie studios also use this capability for things like online games and chat.
