According to a report from Advanced Television, DirecTV is working on plans regarding upgrades to an Ultra HDTV signal. A 1080p HD signal offers 1080 horizontal lines of vertical resolution, and DirecTV’s Ultra HDTV will have both “4000-line and 8000-line services” according to the company.
The massive upgrade in resolution with both 4K and 8K technologies would enable television manufacturers like Toshiba and Sony to create glasses-free 3D images at multiple viewing angles. For example, Toshiba’s 55-inch glasses-free 3D TV offers 4K resolution, but the 3D mode is limited to 720p. Designed to accommodate multiple viewers within nine different regions, the television utilizes extremely small lenses to split the video feed up into two views at different angles. The user calibrates the views using face-tracking software that is built into the TV set. Toshiba has already released the television in Japan and Europe, but it comes with a hefty $10,000 price tag.
