9、r production and international exchange of HDTV 3DTV programmes. The ITU Radiocommunication Assembly, considering a) that 3DTV programmes are already being produced in several countries; b) that the high-definition common image format of 1920 1080 pixels at 60, 50, 30, 25 and 24 frames a second has
10、already been agreed as the international exchange format for HDTV programmes; c) that the parameters of the two HDTV 3DTV signals (Le and Re)2exactly match the parameters for HDTV specified in Recommendation ITU-R BT.709; d) that the parameters specified in Recommendation ITU-R BT.709 meet the quali
11、ty goals set for HDTV 3DTV; e) that programmes produced and archived using the parameters specified in Recommendation ITU-R BT.709 will have long-term reusability; f) that the relative timing between the Le and Re data streams at the point of exchange needs to be sufficiently accurate to allow downs
12、tream devices to resynchronize the frames for display, recommends 1 that the serial digital interface parameters defined in Annex 1 should be used for production and international exchange of HDTV 3DTV programmes; 2 that Note 1 be considered part of the Recommendation. NOTE 1 Compliance with this Re
13、commendation is voluntary. However, the Recommendation may contain certain mandatory provisions (e.g. to ensure interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall” or some other obligatory language su
14、ch as “must” and the negative equivalents are used to express requirements. 1In the context of this Recommendation, the term 3DTV is used to convey a stereoscopic image or image pair. 2Le and Re are abbreviations for Left eye and Right eye, respectively. 2 Rec. ITU-R BT.2027 Annex 1 This Recommendat
15、ion covers interfaces for the 4:2:2 sampling lattice at the frame rates of 24, 24/1.001, 25, 30 and 30/1.001 with 8 and 10-bit depth. These interfaces for 3DTV images shall carry the Le and the Re images as two full resolution images along with audio and other data. The Le image and the Re image sha
16、ll have the same image format structure. The electrical or optical characteristics of each link of the interface shall be in conformance with Recommendations ITU-R BT.1120 and BT.1367. 1 Dual 1.5 Gbit/s interface One link of this interface shall carry an Le image and the other link shall carry an Re
17、 image, and shall be identified by the payload identifier. Each Le and Re image of the stereoscopic image pair shall be of the same format and structure and shall be constructed as an individual 10-bit interface in accordance with Recommendation ITU-R BT.1120. NOTE Each link can be treated as a 2D s
18、tream and can be processed with existing 2D equipment. The timing difference between the serial digital clocks and EAV / SAV of the Le link and the Re link shall not exceed 400 ns at the source. This difference should be taken into consideration when designing systems and destination equipment input
19、 stages. The 10-bit interfaces so constructed shall contain timing reference code words (SAV/EAV), line numbers and line-based CRCs as defined in Recommendation ITU-R BT.1120. Each parallel 10-bit interface shall be frame-, line- and word-aligned, having an interface clock frequency of 148.5 MHz or
