Abstract

3D TV technology has matured much and has been commercially available for several years. However, its use has not been high in comparison to 2D viewing. Herein disclosed is a system which allows for a viewer to watch 2D TV in 3D without affecting the other viewers from watching the 2D TV as normal. This is acheived by the viewer wishing to watch in 3D using augmented reality glasses that superimpose the second necessary image for each frame to produce the 3D effect.

Augmented 3D TV

The majority of households own a TV, with a minor subset of these being 3D TVs. Whilst 3D television and 3D media consumption has seen a renaissance, the uptake of 3D TV is still limited by the simple fact that 3D technology is expensive and results in comparable TV screen sizes being disproportionately priced. The reason that 3D TV systems are expensive is simply down to the fact that the production cost involved are higher: for "passive" systems provide circular polarisation at an increased hardware expense; "active" systems provide linear polarisation and require expensive glasses to match them, but will provide a diminished user experience through tilting their head.

    This idea removes the requirement of a 3D TV to consume 3D media through the combination of augmented reality and a traditional 2D television. We propose a system which turns ordinary 2D TV viewing into 3D TV viewing by the use of augmented reality (AR). We assume that a user has:


 A TV displaying in 2D.


 A media system (such as a BLU-RAY player) that is capable of reading 3D media.


 AR glasses.

The media system sends one data frame to the TV and the companion data

frame is sent to the AR glasses. The companion data frame is overlaid on the TV in one eye by the AR glasses such that the user is able to observe both data frames simultaneously to form 3D image.

  The advantages include:
 Not preventing anyone who does not have the AR glasses from watching the media on the 2D TV, a limitation of current 3D TVs.


 Enabling the use of an existing 2D TV (cheaper than 3D TVs) to observe 3D media.


 The media player would be comparatively cheap compared to a 3D TV system.


 No polarisation mechanism is required which will eliminate the "head-tilt" problem with active polarisation glasses.


 Not requiring fast screen refresh rates only available on high-end expensive TVs.


 The system being adapted to be used in cinemas which would avoidance of costly 3D projector and enable the cinema screen to be used simultaneously for 2D and 3D film screenings.

A media player that is capable of reading or producing 3D content is

assumed. This may be from a storage medium such as a BLU-RAY disc or dynamically generated 3D data that is provided by the media device as a result of inferring 3D content. It is assumed that this data is such that image pair frames are produced which when observed by separate eyes at the same time will provide the illusion of 3D objects.

    Figure A illustrates from the media player, one of data frames being sent to the 2D TV and the other being sent to the AR glasses that a user is wearing. The 2D TV is agnostic of the existence of the AR glasses, it wi...
