New ITU-R Question 128/6: Digital three-dimensional (3D) TV broadcasting 1)What are the user requirements for digital 3D TV broadcasting systems? 2)What are the requirements for image viewing and sound listening conditions for 3D TV? 3)What 3D TV broadcasting systems currently exist or are being developed for the purposes of TV programme production, post-production, television recording, archiving, distribution and transmission for realization of 3D TV broadcasting? 4)What new methods of image capture and recording would be suitable for the effective representation of three-dimensional scenes? 5)What are the possible solutions (and their limitations) for the broadcasting of 3D TV digital signals via the existing terrestrial 6, 7 and 8 MHz bandwidth channels or broadcast satellite services, for fixed and mobile reception?

New ITU-R Question 128/6: Digital three-dimensional (3D) TV broadcasting 6)What methods for providing 3D TV broadcasts would be compatible with existing television systems? 7)What are the digital signal compression and modulation methods that may be recommended for 3D TV broadcasting? 8)What are the requirements for the 3D TV studio digital interfaces? 9)What are appropriate picture and sound quality levels for various broadcast applications of 3D TV? 10)What methodologies of subjective and objective assessment of picture and sound quality may be used in 3D TV broadcasting?

Difference betweeen 2D and 3D viewing conditions Viewer perceived disparity (horizontal/vertical): Range of disparity, type of disparity Autostereoscopic displays split the resolution into multiple views, in part the resolution is a function of the disparity Crosstalk leads to ghosting images

Characterization of 3D Content Measurement of average disparity, like TI/SI indicators Objective measurement of the quality of the depth information, e.g. 2D → 3D conversion contains a lot of artifacts

Technology Issues Problem: Different technologies for transmission: 2D+Depth, Left+Right, Multiview Different display technologies: Autostereoscopic, Shutter/Polarized/Anaglyph-Glasses Options: Set a standard with requirements (for example the displayed depth range should not interfere with actual room situations) Define a set of measurements, e.g. depth resolution, crosstalk

Subjective experiment setup Which measurement to use for which application? Example: Paired comparison with split-screen for small differences How can we measure/include the “added value of depth”?
