Blu-ray allows two basic formats for titles. BD titles authored with menu support are in the BD-MV (Blu-ray Disc Movie) format. BD-MV discs contain audio, video, and other streams in Blu-ray's BD-AV (MPEG-2 TS) Container. In addition, BD-MV discs normally include interactive menus using BD-J (Blu-ray's Java implementation). BD-MV is the format intended to replace standard definition DVD.
Video and Audio FormatsBD-MV supports high definition video encoded according to MPEG-2, AVC (MPEG-4 Part 10), and VC-1 specifications. Supported audio formats are LPCM (uncompressed / mandatory), AC-3 (Dolby Digital / mandatory), DTS (mandatory), Dolby Digital Plus (optional), DTS-HD (optional), Dolby TrueHD (lossless / optional), and DTS-HD Master (lossless / optional). Audio formats listed as mandatory must be supported by every player. Due to the relatively small size of even uncompressed audio, compared to the total size of BD media, it's common to find uncompressed or losslessly compressed audio on many commercial discs.
ResolutionBD-MV supports both high definition (HD) and standard definition (SD) content. Typically main features are in high definition resolutions, while extras may all use SD or use a combination of HD and SD resolutions. Picture in Picture (PiP) video is all SD.
Supported resolutions for HD video are 720p (1280x720 Progressive), 1080i (1920x1080 Interlaced), and 1080p (1920x1080 Progressive).
FramerateStandard analog video framerates of 25fps (PAL) and 29.97fps (NTSC) are supported for SD video. For HD video, supported framerates are 25fps and 30fps for interlaced HD video as well as 24fps progressive. Video encoded in 720p may be at 24fps, 50fps, or 60fps.
ProfilesBD-MV has three distinct profiles associated with it. Different profiles support different features and require different hardware. The reason for multiple profiles was the lack of a finished specification at the time the first players were designed. Since hardware requirements for more advanced BD-MV profiles build on the requirements for earlier profiles, some first and second generation players may be capable of being upgraded to support the final BD-MV profile.
The three BD-MV profiles are Profile 1.0, also known as Grace Period Profile or Initial Standard Profile, Profile 1.1, also known as Final Standard Profile or Bonus View, and Profile 2.0, also called BD-Live.
