Conversion question

post #1 of 4
Thread Starter 
Just a quick query regarding the future of 3d and the competing formats. As I understand it, most existing 3d "ready" displays will take either field-sequential 3d (i.e. the optoma hd66) or checkerboard (i.e. most lcds). Is there currently in existence, or in development, a piece of external equipment that can convert between the two formats. Specifically, if I purchase an hd66 now, is it likely that down the road if the world sticks to a checkerboard 3d format, that there will be a relatively inexpensive converter/adapter?

My guess is that there will at some point be a software checkerboard to field sequential and vice versa solution (tell me if I'm wrong on this point), so that graphics running through my video card can be converted. What I'm wondering about is a converter that would take cable/satellite tv and do the same as I'll presumably be able to do with web/blu-ray 3d dvd content on my pc via software?

Both field sequential (with the IR transmitter for the glasses in the player, not the TV) and checkerboard are legacy "3D Ready" formats. Current 3D displays and players support the common HDMI 1.4a standard, which uses Frame Packing, Side-by-Side and Top-and-Bottom formats.

There are some converter boxes available and announced to convert from a HDMI 1.4a signal to checkerboard, but I'm not sure right now about frame sequential.

I think you are confusing things. Field-sequential is an old legacy format that was used for 3D DVDs and many systems from the late 90's/early 2000 that worked on CRT displays. The format encoded each eye's view in an interlaced fashion. Although there are still interlaced format monitors (like the Zalman Trimon I own) they are generally known as line-interleaved LCDs. Checkerboard is TI's 3D standard for DLP, not LCD. Checkerboard is mainly used in rear-projection DLP systems like those from Mitsubishi. Both of these formats are considered legacy and it is doubtful they will make a comeback.

Field Sequential is the way all 3D displays or TVs that use Active glases actually are displayed. It is also the way Nviidia 3D vision sends it's signal to 3D capable displays. The new Blu-ray 3D output format is sent to 3D TVs in packed field sequential format where each buffer actually conatins both the full right right eye field and the full left eye field.
