3-D TV on Mobile Phones
.

This is an interesting European funded research project which began January 2008 called MOBILE3DTV. The purpose of the project is to demonstrate the viability of the new technology of mobile 3DTV. The project develops a technology demonstration system for the creation and coding of 3D video content, its delivery over DVB-H (Digital Video Broadcasting - Handheld) and display on a mobile device.

Historical background
Despite the images it evokes of high-tech wizardry, rudimentary 3-D technologies have been around practically since the dawn of filmmaking. The first ever attempt came in 1890, when the British film pioneer William Friese-Greene invented a process in which two films were projected side by side on screen, and the viewer looked through a stereoscope to converge the two images. As early as 2003, Sharp launched a 3-D mobile phone in Japan and Korea’s SK Telecom launched a 3-D phone – from Samsung – in 2007, and Japan’s Hitachi just launched one in 2009. Apple’s iPhone also supports three-dimensional television, but can currently only be viewed with special glasses. Mobile3DTV is developing the core elements of the next generation of three-dimensional television for mobile devices.

Technical specifications
The major challenge has been choosing the optimal format for representing 3-D video for mobile delivery and for that reason, the project decided to build its system around the EU standard known as Digital Video Broadcasting – Handheld (DVB-H). Further challenges to provide comfortable and enjoyable 3-D viewing were overcome by employing what is being termed as the so-called "auto-stereoscopic displays". In essence the displays apparently remove the need to wear those awkward Blue Lense/Red Lense cardboard glass that are dished out in childrens magazines that gives the viewer of an image that look elevated and solid from off the page.

According to the research “Auto-stereoscopic displays use additional optical elements aligned on the surface of an LCD, to ensure that the observer sees different images with each eye.” Moreover, as mobile devices are normally watched "by a single observer, two independent views are sufficient for satisfactory 3-D perception.”
