ITU-R BT.2024 1 RECOMMENDATION ITU-R BT.2024 HDTV digital image systems for the production1and international exchange of 3DTV2programmes for broadcasting (2012) Scope This Recommendation spec

9、ifies the digital image systems that should be used worldwide for the production and international exchange of 3DTV programmes for broadcasting. This Recommendation does not define image acquisition parameters such as camera shutter angle or camera image synchronization. The ITU Radiocommunication A

10、ssembly, considering a) that since programme producers and broadcasters are producing 3DTV programmes for domestic broadcasting and for international programme exchange, there is a need to develop a set of ITU-R Recommendations to be used worldwide in the production of 3DTV programmes for broadcasti

11、ng, in order to facilitate their international exchange; b) that 3DTV broadcasters, programme producers and distributors need to preserve the value and quality of their programmes for television broadcast use and therefore they have an interest in protecting their programmes from technical obsolesce

12、nce; c) that, consequently, the 3DTV image systems to be used worldwide, now and in the foreseeable future, for the production and international exchange of 3DTV programmes for broadcasting should provide the best technical and perceptual picture quality that current systems already widely implement

13、ed in the world can achieve; d) that the 1 920 1 080 HDTV systems specified in Part 2 of Recommendation ITU-R BT.709 Parameter values for the HDTV standards for production and international programme exchange are the television imaging systems that provide the highest picture quality, recommends 1 t

14、hat, for the production and international exchange of 3DTV programmes, the 1 920 1 080 HDTV systems specified in Part 2 of Recommendation ITU-R BT.709 should be used3; 1This Recommendation uses the term “production” in the same way as Recommendation ITU-R BT.1662, which indicates that the production

15、 section of the total television broadcasting chain includes the functions of acquisition and post-production and ends with the finished programme master. 2In the context of this Recommendation, the term 3DTV is used to convey a stereoscopic image or image pair. 3The 60/P and 50/P HDTV systems will

16、ultimately be used for this purpose. 2 Rec. ITU-R BT.2024 2 that the sampling lattice normally used for the 3DTV programme master for broadcasting should be 4:2:2, and the sampling lattice of 4:4:4 (R.G.B.) may be used during the production process involving complex processing; 3 that the preferred

17、bit depth used for 3DTV should be 10 bits/sample4; 4 that the Le and Re images5of a 3DTV image pair should be internationally exchanged as two full-resolution 1 920 1 080 images having the same pixel structure and picture repetition rate6; 5 that the relative timing between the Le and Re images at t

18、he point of exchange needs to be sufficiently accurate to allow downstream devices to resynchronize the frames for display; 6 that the choice of the image parameter values among those specified in this Recommendation should be included in the metadata that accompanies the images. 4In some cases 8, bits may be used. 5Le and Re are abbreviations for Left eye, and Right eye, respectively. 6In some particular circumstances, a broadcaster may choose to depart from the provisions in this recommends.
