The Consumer Electronics Show (CES) in Las Vegas last month was overrun with companies demonstrating 3D television systems for the home. But despite the impressive viewing experiences on offer, the spectre of a lengthy battle between competing formats hangs over the latest shiny offerings.
TV studios and hardware companies alike are now building on the public's rediscovered love of 3D movies. Satellite broadcaster Sky recently treated press to examples of soccer games and boxing matches filmed in 3D by strapping two regular cameras side-by side, and Panasonic last week started to make 3D Blu-ray video discs at its Hollywood factory.
However, anyone interested in a 3D system for the home must pick between three or more very different and incompatible technologies. At present, material designed for one system usually cannot be played on another.
