Sisvel Technology Shows New 3D Tile Format
At IFA 2010 Sisvel Technology is demonstrating the 3D Tile Format, the new solution to improve 3D broadcasting trough a creative way to format two stereoscopic images. This new technology enables delivery of HD 3D content with a higher quality than current solutions and allows broadcasters to transmit a single video service to 2D and 3D audiences. Backwards compatibility of the 3D Tile Format guarantees that consumers with a traditional 2D TV set can still enjoy the service in 2D format.
Current Issues in 3D Broadcasting
The idea behind 3D video is the transmission of two separate images (Left & Right), to reproduce human stereoscopic vision, packed in a single stream. The current systems squeeze the Left and Right images into a single High Definition frame and the service provider reuses part of the existing production and the entire distribution infrastructure. This approach not only causes a loss in the video quality, halving the vertical or horizontal resolution of the source image, but also makes the 3D transmission unsuitable for viewing on 2D TV receivers. The challenge was to avoid the drawbacks of the current frame packing techniques.
Sisvel Technology's Solution to Improve 3D Broadcasting
To overcome these drawbacks in 3D broadcasting, Sisvel Technology has created the 3D Tile Format, a solution allowing the integrated storage of two stereoscopic 720p frames into a single 1080p frame. The reconstructed Left and Right pictures keep their original resolution and will not be affected by the unbalance of the Vertical and Horizontal resolution. The layout of the images within the Tile Format, together with standard compliant technologies developed by Sisvel Technology, seamlessly allows the decoding of 2D video from the 3D transmission.
