7、:2012 Page 2 of 26 pages Foreword SMPTE (the Society of Motion Picture and Television Engineers) is an internationally-recognized standards developing organization. Headquartered and incorporated in the United States of America, SMPTE has members in over 80 countries on six continents. SMPTEs Engine

8、ering Documents, including Standards, Recommended Practices and Engineering Guidelines, are prepared by SMPTEs Technology Committees. Participation in these Committees is open to all with a bona fide interest in their work. SMPTE cooperates closely with other standards-developing organizations, incl

9、uding ISO, IEC and ITU. SMPTE Engineering Documents are drafted in accordance with the rules given in Part XIII of its Operations Manual. SMPTE ST 435-2 was prepared by Technology Committee 32NF. Intellectual Property SMPTE draws attention to the fact that it is claimed that compliance with this Sta

10、ndard may involve the use of one or more patents or other intellectual property rights (collectively, “IPR“). The Society takes no position concerning the evidence, validity, or scope of this IPR. Each holder of claimed IPR has assured the Society that it is willing to License all IPR it owns, and a

11、ny third party IPR it has the right to sublicense, that is essential to the implementation of this Standard to those (Members and non-Members alike) desiring to implement this Standard under reasonable terms and conditions, demonstrably free of discrimination. Each holder of claimed IPR has filed a

12、statement to such effect with SMPTE. Information may be obtained from the Director, Standards or that a certain course of action is preferred but not necessarily required; or that (in the negative form) a certain possibility or course of action is deprecated but not prohibited. The keywords “may“ an

13、d “need not“ indicate courses of action permissible within the limits of the document. The keyword “reserved” indicates a provision that is not defined at this time, shall not be used, and may be defined in the future. The keyword “forbidden” indicates “reserved” and, in addition, indicates that the

14、 provision will never be defined in the future. A conformant implementation according to this document is one that includes all mandatory provisions (“shall“) and, if implemented, all recommended provisions (“should“) as described. A conformant implementation need not implement optional provisions (

15、“may“) and need not implement them as described. 3 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and

16、parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent edition of the standards indicated below.

Figure 1 shows

22、the overall block diagram of the 10.692 Gb/s interface which can carry 40962160/24P/4:4:4, 38402160/30P/4:4:4 or up to four pairs of 20481080/24P/4:4:4 or 19201080/60I/4:4:4 signals. The outline of the data mapping process shall be as follows: The 10-bit Basic Streams shall be packed into arrays of

23、8 bit words. The generated byte array shall be channel coded as 8B/10B encoded data. The blocks of encoded data shall be interleaved and serialized into the 10.692 Gb/s serial stream. HANC Data in some of the Basic Streams are not interleaved into 10.692 Gb/s stream in the case of mapping Mode B, C

24、or D. Details are defined in Section 6.2, Section 6.3, and Section 6.4. Figure 1 illustrates the signal processing involved at the TX and RX ends of the transport. Default data values (040h for Y data and 200h for CB/CRdata) shall be inserted into unused HANC Data area of a Basic Stream if it has no

25、t been mapped onto the 10.692 Gb/s stream. SMPTE ST 435-2:2012 Page 5 of 26 pages Figure 1 Overall Block Diagram 6 Basic Stream Data Mapping This section defines 4 data mapping structures. Mode A and Mode B shall be used for System 1.1 through System 4.3 images. Mode C shall be used for System 8.6 i

26、mage exclusively. Mode D shall be used for System 8.2 through System 8.7 images, up to four pairs of System 2.2 through System 2.6 images or up to two pairs of System 4.1 through System 4.3 images. Transmission of up to 5 Basic Streams as defined in SMPTE ST 435-1 is possible in Mode A, up to 6 Basi

27、c Streams is possible in Mode B and up to 8 Basic Streams is possible in Mode D. All Basic Streams that are mapped together onto a 10.692 Gb/s stream shall have the same frame rate and the same number of horizontal samples per line. The placement of the ancillary data including the payload identifie

28、r as defined in SMPTE ST 352 shall be immediately following SAV of the line(s) specified in the Basic Stream interface document for Mode B, Mode C and Mode D. The word clock frequency of each Basic Stream, as defined by SMPTE ST 435-1, shall be 148.5 MHz or 148.5/1.001 MHz. The word clock frequency

29、shall be locked to the serial clock frequency (10.692 GHz or 10.692/1.001 GHz). 6.1 5-Channel Mode (Mode A) Up to 5 Basic Streams may be embedded into the 10.692 Gb/s stream using mapping Mode A. The mapping shall maintain all the information included in each of the 5 Basic Streams. The 8B/10B encod

30、ed 50-bit data block data from each Basic Stream shall be multiplexed into a single stream by the 50-bit block interleaving. The detail of the 50-bit block packing is defined in Section 6.1.1. The Channel 1 Basic Stream data shall always be present for encoder and decoder synchronization. Other chan

31、nels, when not used for image data, shall be filled with Stuffing Data.

33、 and 8B/10B Encoding 4-word (40-bit) data blocks of the source Basic Stream data starting from the first SAV data shall be used for the blocking process. Each 40-bit data block shall be packed into five 8-bit words and then shall be 8B/10B coded as defined in Section 11 of ANSI INCITS 230. Consequen

34、tly a 50-bit encoded data block shall be generated from a 40-bit source data block. Figure 3 defines the blocking process. Encoding disparity in a 10.692 Gb/s stream shall be alternated at every 10-bit word. Initial value of negative disparity shall be assigned to CH 1 first SAV word of each line. F
