Patent Compliments Recently Issued US Patent Covering Core Processes for Conversion and Transmission of 3D content
SANTA MONICA, January 6th, 2003 – DDD Group plc (“DDD”) announces that it has received notification of allowance of its key “Dynamic Depth Cueing” (“DDC”) patent in Europe. DDC is a core DDD technology that enables existing film or video images to be converted for display in stereo 3D.
The new European patent extends DDD’s coverage of technologies that allow the conversion of existing 2D content libraries to 3D and their delivery in a format that remains compatible with today’s 2D televisions. The DDC patents have important ramifications for enabling a range of mass market 3D applications including the conversion of existing film and video libraries for viewing on the emerging generation of 3D ‘without glasses’ LCD and plasma televisions via a single DVD or television broadcast.
Dynamic Depth Cueing encompasses the recreation of 3D depth data from existing 2D material, in essence regenerating 3D information that is not recorded when a conventional film or video camera is used. Once the 3D data is recreated, it is then used to manipulate the underlying 2D image, allowing 2D images to be transformed to 3D for a wide variety of 3D display formats ranging from large format IMAX® films to the latest generation of 3D displays.
The addition of the DDC patent brings to 8 the total number of issued patents held by DDD and its subsidiaries. In addition to the 3D conversion patent, DDD has other core patents relating to efficient delivery of 3D data along with an unaltered 2D image and the tracking of a viewer’s head for 3D display systems. DDD’s 3D conversion, transmission and display technologies are marketed under the brand name TriDef™.
DDD CEO Chris Yewdall said “The notice of allowance of DDC in the Europe complements our US patent for DDC that was issued under US Patent Number 6,477,267 in the United States in November 2002. We are pleased to have received this critical patent coverage in both Europe and the United States we are looking forward to building upon this both commercially and technically in the future.”
DDD is transforming television with glasses-free 3D TV. Its patented technologies enable 3D viewing without glasses; supply of 3D content through 2D to 3D conversion; and 3D transmission over existing networks. DDD is quoted on the London Stock Exchange’s Alternative Investment Market (AIM:DDD).
