Our friend Mari at the official Motorola Blog just got back from checking out the 3D demo at Cable-Tec and was able to dig up a few extra details in addition to sharing her impressions. Overall she said the circular polarized and active shutter demos both “looked good” but each was driven by a different set-top-box so it was hard to do a fair a to b comparison. This also makes us continue to wonder how compatible these two 3D display technologies are — we suspect they are compatible and that this was just to prove that both IPTV and QAM worked as delivery methods. The most interesting tidbit is the fact that, thanks to new Multiview Video Encoding techniques, the 3D stream only requires about 30 percent more throughput than the same image in 2D. This isn’t as much as Panasonic is claiming the new 3D Blu-ray spec will require, which is estimated at 50 precent. One other thing we’re left wondering is what the frame rate of the demo was, but earlier this week CableLabs did confirme that the demo is 1080p and that the SCTE has already added 1080p at 60 fps to its encoding standards. We assume the frame rate had to be at least 30 fps per eye though, because otherwise the flicker would probably be noticeably annoying.
