DDD Group PLC Awarded Key United States Patent Covering 2D To 3D Conversion

Patent Bolsters DDD's Portfolio Covering Core Processes for Conversion and Transmission of 3D content

SANTA MONICA, July 10, 2002 - DDD Group plc ("DDD") announces that it has received notification of allowance of a key U.S. patent covering "Dynamic Depth Cueing" ("DDC"), a core DDD technology that enables existing film or video images to be converted for display in stereo 3D.

The new US 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.

DDC is already available in solutions for the following applications:

	DDD's TriDef™ 3D Television system is already being successfully used at trade shows and promotional events displaying 3D presentations that have been converted from the customer's original 2D marketing materials;
	DDD's TriDef™ Transformer PC software tool allows end users to quickly and easily convert their 2D images for display in 3D with the TriDef™ 3D Television systems. The 3D images may also be composed into compelling Microsoft PowerPoint 3D presentations;
	DDD's TriDef™ PC 3D media player software delivers broadcast quality 3D images generated in real time by combining 2D content with embedded 3D depth information.

The addition of the DDC patent, brings to 7 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's growing patent portfolio covers the core methodologies for converting 2D content to 3D and for delivering 3D information along with an unchanged 2D image that is compatible with today's digital and analogue delivery systems including DVD discs and broadcast television. DDD has established an exceptionally strong patent position and, as part of its licensing program, is offering licensing terms to content creators, 3D display developers, as well as organizations seeking to enter the emerging mass markets for professional and consumer 3D viewing.

DDD CEO Chris Yewdall said "The notice of allowance of DDC in the United States establishes our leadership in the field of 3D conversion for our customers. Over the past several years we have developed an extensive patent library that uses these core DDC patents as their foundation. We are pleased to have received this critical patent coverage in this area and 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).
