True 3-D capability on Blu-ray Disc...

[DaViD Boulet]

Since BD allows the second video stream (what is only a PIP function on HD DVD) to be encoded in full 1080p24 resolution, this stream could be used to encode the alternate left/right eye-angle of a 3-D film.

Standard BD players would play the movie normally in 2-D with the secondary video stream accessible as a normal PIP function.

However, 3-D-capable BD players could be designed to access the secondary video stream and output it via a second HDMI interface for a second projector simultaneously, or to "matrix" the two video streams together via one of several means, such as by alternating each frame from each stream to create a Left, Right, Left, Right, Left, Right cadence with a 48 kHz signal that could then be synched with LCD shutter glasses.

These later enhancements to BD hardware capability would be *** Cheap and Easy *** and would only require a minor modification to BD-J specs.

What do you guys think? IMO, now is the time to start a conversation about this while BD-J is still in the early stages and players are still undergoing lots of flux with implimentation of BD-J. It should not be necessary to debate the inferior alternatives available with retro-fitting 3-D software into existing specs via interlacing and color-filters. Dual 1080p24 video streams would be the first time TRUE FULL-FIDELITY 3-D would be available via consumer media: and it would enable full backwards compatibility with 2-D viewers so one Disc solution would work for everyone.
