DDD Group plc Signs Agreement with Jamster; Conversion and Distribution of 3D Mobile Telephone Content.

SANTA MONICA, Calif. -- DDD Group plc (LSE:DDD), the 3D software and content company, today announces that it has signed a Memorandum of Understanding with Jamster! International Sarl ("Jamster"). The Memorandum permits Jamster to use DDD's offline 2D-to-3D content conversion solution to convert Jamster's 2D mobile content to 3D for publishing to 3D mobile telephone subscribers.

Under the terms of the agreement, Jamster will provide images from Jamster's content library for conversion to 3D using DDD's high quality offline conversion process. Jamster will then act as DDD's primary content aggregator for the converted 3D images in key markets, including Asia and Europe.

DDD will undertake the 2D-to-3D conversion at its own expense, and the two companies will share in the profits from the chargeable download of the converted images by 3D mobile telephone subscribers internationally. The companies expect that the 3D content libraries will be available from Jamster and Jamster's global affiliates in conjunction with the launch of the first handsets from DDD's DDD Mobile(TM) mobile telephone 3D content solution licensees.

Nigel Hawkes, Director of European Business Development of DDD, said, "The alliance with Jamster is a strong foundation for DDD's mobile telephone content strategy. Jamster has a well developed content library supported by a sizeable international distribution infrastructure. As DDD secures handset licensees for DDD Mobile, Jamster's existing distribution network should yield rapid and cost-effective access to the 3D mobile telephone subscribers from which DDD can expect to derive incremental content-based revenues."

Commenting on the agreement, Jamster said, "As the leading provider of mobile content, Jamster is continually seeking to deliver the most innovative entertainment to our customers. The new generation of 3D mobile telephone handsets delivers a very impressive viewing experience that we believe will drive incremental growth in the mobile content market. With DDD's high quality 2D-to-3D content conversion process, we can cost-effectively realize new revenue streams from our existing content investment."

Notes to Editors

About DDD

DDD, also known as Dynamic Digital Depth, is transforming the viewing experience with applications for glasses-free 3D displays. Its patented technologies enable 3D viewing without glasses, simple integration of computer graphics applications with 3D displays, 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 (LSE:DDD).

--A new category of flat screen LCD and plasma displays are being developed and marketed by major consumer electronics companies that provide stereoscopic 3D images without the need for the viewer to wear glasses. Stereoscopic 3D images appear to have natural in- and off-screen depth. 3D displays have already been included with mobile telephones in Japan and in desktop PC displays and notebook computers in North America and Japan.

--In 2003 and 2004, DoCoMo introduced two models of Sharp mobile telephone that included a 3D LCD display developed by Sharp Corporation. DoCoMo sold approximately 2.8 million 3D mobile telephones in Japan.

--DDD's solutions provide an important bridge between conventional two dimensional (2D) applications and content and the new 3D displays. Normal 2D pictures, video and computer graphics images are manipulated by DDD's patented software, enabling them to be displayed on 3D displays without requiring the content to be created specially for a 3D display. DDD recently announced the ability to automatically convert still photographs and DVD video to 3D without any preprocessing of the 2D image.

--DDD licenses these software applications, marketed under the TriDef(R) and DDD Mobile(TM) brand names, to manufacturers for inclusion with the 3D display products supplied to end users. DDD also licenses the software directly to end users who already own 3D displays and through an international sales channel. Sharp Corporation and DDD entered into a multiyear software licensing agreement in October 2003 that allows Sharp to include a bundle of five of DDD's 3D software applications with Sharp's Actius range of 3D notebook PCs sold in Japan and America.

--DDD expects to license the DDD Mobile software library to handset makers who wish to include 3D LCD displays in a variety of wireless devices, including next-generation smartphones and PDAs. The licensing arrangements are expected to yield a per unit royalty to DDD based on the number of wireless devices manufactured by the licensee. These projects may also yield one-time development and integration fees associated with assisting the manufacturer in the successful integration of the DDD software with the 3D wireless device.

--DDD also intends to generate income through the conversion of existing libraries of premium mobile content, including wallpaper, animations and movies. The company expects to participate in a share of the income paid by wireless subscribers who download 3D content that has been converted to 3D by DDD.

--DDD is currently expanding the product range to allow its content solutions to be used on future 3D display products, including consumer television.

--Jamster is a leading wireless content mediation company offering robust mobile services by providing access to more then 50,000 pieces of mobile content, including ringtones, images, games and community services.

--With support for a broad variety of handsets from industry-leading manufacturers, and the most flexible options for content delivery to the handset, Jamster enables carriers to generate new revenue from their existing subscriber base while promoting exciting new content offerings to aid subscriber acquisition.
