3D testing is on. This will allow TV manufactures and cable companies to begin having their equipment tested for 3D interoperability. Along the way CableLabs has also confirmed that many of the existing set-top boxes will work with "frame-compatible" 3D formats -- like side by side pictured above. This is exactly what DirecTV announced it would use and is the very same standards that HDMI added to the spec. Basically it allows providers to dedicate the same amount of bandwidth to 3D as it was to 2D. Of course this means that the resolution is cut in half (horizontally in the case of side by side) but we're told that sharpness isn't as perceivable in 3D as it is in 2D and after seeing the DirecTV 3D demo at CES, we believe it. Unlike the adoption of HD, it doesn't look like the cable industry is going to let the satellite companies run away with the new technology unchallenged like last time.
