TDVision Systems, a developer of 3D digital infrastructures and visualization systems, will use CES this week to showcase its encoding/decoding system for hi-def 3D streaming that supports Blu-Ray (1080p) and the same for broadcast content up to 1920x1080 (per eye). TDVision calls it "Stereoscopic HD3D."
Since showing a prototype of the 3D system at The NAB Show last spring, the Irvine, Calif.-based company said it has optimized its systems and will demo at CES how “this can be in your home today, working over existing pipelines, running on every existing and future 3D display at the best native resolution, even in 2D HD for backwards compatibility.”
How does it work? TDVision said its patented technology has been implemented as special coding in the MVC MPEG-4 H.264 extension recommendation initiative by comparing the difference between left and right channels. This process “eliminates redundant information and optimizes the bandwidth” required for a given infrastructure (i.e., DBS, cable, ATSC 1.0/2.0, and Blu-ray).
TDVision said its codec (“TDVCodec”) can deploy HD 3D with no loss in color, quality, fps, or resolution. It said it does not work like other existing 3D technologies such as “spatial squeezing,” which the firm said “defeats the purpose of realistic 3D imagery by cutting resolution [by] more than half and at times showing only 25 percent of the original pixels after formatting and presenting to a 3D-ready display.”
One eye-catching element does remain from the good old days of 3D about half a century ago: Viewers must still wear special glasses (dubbed “XpanD”) to appreciate the 1080 3D.
