Claim Text:
1. Video device for processing a video signal, the device comprising: an input/interface unit to receive the video signal comprising video data representing either three dimensional video (3D) content formatted according to a 3D format or two dimensional video (3D) content formatted according to a 2D format, the video signal having a 2D frame and a control structure of a 2D format, the 3D format having at least two 3D subframes for constituting a single 3D frame and being one of a set of possible 3D formats, a processor for providing a 3D status signal indicative of the format of the video signal, the processor being arranged for determining respective format scores for a number of the possible 3D formats by processing the video data according to respective predetermined format properties for deriving and comparing the respective 3D subframes, which determining said respective format scores for said number of the possible 3D formats is arranged in a predetermined order, setting the 3D status signal based on an assessment of the respective format scores to indicate the format of the video signal, when the assessment of the format scores provides a predetermined level of confidence, and wherein at least one of the possible 3D formats comprises left and right 3D (L and R) subframes arranged in the 2D frame according to a left/right polarity, and the processor is arranged for, when determining the format score, determining a polarity score based on a predetermined distribution of depth occurring in the 3D frame, and setting the 3D status includes setting a left/right polarity status signal based on an assessment of the polarity score.
