NHK working on Hybridcast interactive TV platform (video)
NHK is working on Hybridcast (an entirely different system to the Hybridcast 3D-delivery setup it demonstrated last year), a system that uses the internet to make vanilla TV broadcasts interactive. It works by pushing HTML5 overlays to your tablet and TV, so you can play along with quiz shows or follow a travelogue from the comfort of your couch. The company is planning to build a set-top-box with the technology ready for sale next year, with integrated TVs hoped to arrive from Sony, Toshiba, Panasonic, Sharp and Mitsubishi shortly afterward. You can see what the residents of Japan can expect by watching the video after the break.
NHK demos Hybridcast streaming, teams up internet and cable TV for superior 3D delivery
With all the hubbub surrounding competing 3DTV technology, it's easy to forget the all important delivery process: how is your TV getting its content, and what does it mean for the viewer? It may seem trivial, but the answer is all-too important to the folks at NHK, who are hoping to facilitate Full HD delivery for 3D content using a new hybrid broadcast system. Think you already have Full HD 3D? Think again: most broadcast 3D content is delivered via side by side transmission, forcing two images (one for each eye) into a single 1080p frame. This allows 3D content to pipe through existing HD channels, but when the separate images are reconstituted and upscaled, resolution and picture quality suffer. NHK hopes to resolve this by fusing broadcast transmission with broadband streaming, what it calls Hybridcast. In a recent dual-stream demo, NHK sent the image for one eye over standard HD TV broadcast pipes, and the other through those wondrous internet tubes, eventually reassembling the two streams into a single, Full HD image, ready for your hungry eyeballs. This prototype delivery system is little more than a demo right now, but with any luck, it'll be giving us a whole new reason to freak out about broadband bandwidth caps in the near future.
