Adjustable depth and full HD quality could be available to 3D TV viewers from 2012 in a new set of broadcasting formats.
The DVB Group, which sets the standards for digital TV in Europe and many other countries, is working on proposals to improve the current 3D TV experience.
Top of the list for the Phase Two 3DTV standard are Depth Range Control and how to upgrade to Full HD detail from today's half-HD 3D.
David Wood, chairman of the DVB commercial module, said he hopes to make the new standard available to broadcasters in the middle of 2012.
Depth Range Control would allow viewers to adjust the intensity of the 3D effect, to make it comfortable for their eyesight and the room they're in.
Wood said: 'Young people like more depth in the ir pictures than old people do. They like 'poke your eyes out', but older consumers like flatter images.'
An upgrade to 1920x1080p Full HD 3D from today's 960x1080i side-by-side 3D TV could follow two routes, Wood told visitors to the International Broadcasting Conference.
Broadcasters could use the MVC format adopted by Blu-ray, which would need new set-top boxes or TVs. This broadcasts a Full HD picture for the left eye, which can also be watched in 2D, plus extra information which the receiver uses to build the 3D pciture for the right eye.
Alternatively, they could stick with half-HD side-by-side 3D that today's SkyHD, Freesat HD and Freeview HD boxes can receive, but add a second signal with more picture detail that a next-generation receiver could use to create a Full HD 3D signal.
