C (Normative) Descriptor scheme definitions p. 110

C.1 Introduction p. 110

This Annex defines descriptors that are defined in the present document. In particular the following descriptors are defined

3D Video disparity range descriptor scheme in clause C.4.
3D Video display information descriptor scheme in clause C.5.

C.4 3D Video Disparity Range description scheme |R12| p. 110

The 3D Video Disparity Range description scheme may only be signalled in SupplementalProperty element with SupplementalProperty@schemeIdUri set to urn:3GPP:dash:3dVideoDisparityRange:2013. When present the 3D Video Disparity Range description scheme shall be on the Adaptation Set level. The SupplementalProperty@value of 3D Video Disparity Range description scheme shall be present and is defined below using ABNF RFC 5234:

@value="disparityRange"
disparityRange = disparityMinValue disparityMaxValue
disparityMinValue = [%x2D]1*3DIGIT
disparityMaxValue = [%x2D]1*3DIGIT

disparityMinValue and disparityMaxValue are expressed as the minimum and the maximum disparity, in units of pixels, divided by the width of the 3D video content, in units of pixels, multiplied by one hundred. disparityMinValue and disparityMaxValue shall be the same for all Representations included in an Adaptation Set containing this descriptor scheme.

C.5 3D Video Display Information description scheme |R12| p. 111

The 3D Video Display Information description scheme may only be signalled in SupplementalProperty element with SupplementalProperty@schemeIdUri urn:3GPP:dash:3dVideoDisplayInformation:2013. When present the 3D Video Display Information description scheme shall be present on the Adaptation Set level. The SupplementalProperty@value of 3D Video Display Information description scheme shall be present and is defined below using ABNF RFC 5234:

@value="displayInformation"
displayInformation = displayWidth [viewingDistance]
displayWidth = 1*5DIGIT
viewingDistance = 1*5DIGIT

displayWidth and viewingDistance provide actual values for which the stereoscopic 3D video content is optimized and are expressed in millimetres. The displayWidth defines the width of the part of the screen actually used for displaying the 3D video content.
