The drumbeat for HD 3D continues to pick up the pace, and with broadcasters around the globe pushing forward 2010 plans to bring 3D home HDMI has updated the course of its latest 1.4 spec to ensure compatibility between displays and boxes. Quite simply, existing cable and satellite hardware isn't going to be held to the same requirements as Blu-ray and videogame equipment rocking the 3D sticker and expecting compatibility with displays on the way, since they won't be passing the same high quality, high bandwidth dual-stream 1080p images anyway. Additionally, some broadcasters are pushing for HDMI to officially support "Top/Bottom" 3D transmissions they plan to use, which sacrifice resolution while saving bandwidth by shoving left/right images into a single frame. While that should add an entirely new angle to the line counting and claims of "HDLite" (get ready for 3DLite) all viewers can do is wait to hear when or if their hardware will get a software upgrade to 3D (like the one we expect will allow the PS3 to play 3D Blu-ray discs) in the months and years to come, once there's a standard everyone can adhere to of course.
