![]() ![]() Blu-ray 3D uses MVC video encoding, which provides for very high picture quality with an overhead (versus standard Blu-ray) of 50%. A new video codec was developed, based on the Advanced Video Codec (AVC, also known as H.264), called Multi-View Codec (MVC). The video encoding experts in the Motion Picture Experts Group (MPEG) have taken advantage of this fact to reduce the overall bit rate and file sizes for stereoscopic 3D. Since each eye is seeing a slightly different perspective of the same scene, there are many similarities in the frames of video for the left and right eyes. While it would be reasonable to expect that the video file size and bit rate would double (since the number of decoded frames doubles), there are some efficiencies in a 3D video that can be taken advantage of. Decoding a Blu-ray 3D is comparable to decoding two standard Blu-ray movies at the same time. Blu-ray 3D players can be configured to operate in either 2D or 3D (stereoscopic) mode, allowing consumers to upgrade their player and disc collection before they upgrade their TV or display to 3D.īlu-ray 3D movie titles will contain two full Blu-ray quality video streams, one for each eye. In addition, the Blu-ray 3D format allows for Blu-ray 3D titles to be created in such a way that they can be played by a legacy Blu-ray player as a standard 2D Blu-ray movie. ![]() Fortunately, all but the first generation of BD-ROM and BD-R drives are 2x or faster.īlu-ray players capable of playing Blu-ray 3D are backward-compatible, supporting standard (two-dimensional) Blu-ray movies. Blu-ray 3D player software will require a Blu-ray drive that is capable of 2x or faster read speeds. While set-top Blu-ray players will need to be replaced, PC-based Blu-ray player software can be upgraded. ![]() Earlier Blu-ray players will not be able to play Blu-ray 3D titles. The logical format is based on the current Blu-ray audio/video format, but has been extended to provide for stereo 3D video and 3D menus. The physical format for Blu-ray 3D is identical to all other forms of Blu-ray disc. ![]()
