SMPTE 292M-1996

1 ScopeThis standard defines a bit-serial digital coaxial and fiber-optic interface for HDTV component signals operating at data rates in the range of 1.3 Gb/s to 1.5Gb/s. Bit-parallel data derived from a specified source format are multiplexed and serialized to form the serialdata stream. A common data format and channel coding are used based on modifications, if necessary,to the source format parallel data for a given high-definition television system. Coaxial cable interfaces are suitable for application where the signal loss does not exceed an amount specified by the receiver manu-facturer. Typical loss amounts would be in the range of up to 20 dB at one-half the clock frequency. Fiber optic interfaces are suitable for application at up to 2km of distance using single-mode fiber.Several source formats are referenced and others operating within the covered data rate range may be serialized based on the techniques defined by this standard. Revisions to this standard may add other source formats when approved documents are avail-able.2 Normative referencesThe 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 parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent edition of the standards indicated below.SMPTE 260M-1992, T elevision ---- Digital Repre-sentation and Bit-Parallel Interface ----1125/60 High-Definition Production SystemANSI/SMPTE 274M-1995, T elevision ---- 1920 × 1080Scanning and InterfaceANSI/SMPTE 291M-1996, Television ---- Ancillary Data Packet and Space FormattingSMPTE RP 184-1995, Measurement of Jitter in Bit-Serial Digital InterfacesIEC 169-8 (1978), Part 8: R.F .

Thislimits the serial data rate to 1.5 Gb/s although the source format parallel data may allowhigher data rates for RGB or Y, C b , Cr keytypeoperation.4.2Data for each television line are divided intofour areas: SAV (start of active video) timing reference, digital active line, EAV (end of activevideo) timing reference, and digital line blanking as shown in figure 1. The number of words anddefined data in each area are specified by the source format document.4.3Since not all bit-parallel digital televisiondata formats have the same timing reference data, a modification may be required prior tomultiplexing and serialization in order to meet the requirements of clause 5. Where additional words are required for EAV/SAV, data wordsfrom the adjacent digital blanking area shall beused. Modifications are typically made using a coprocessor in the parallel domain.4.4Parameters for referenced source formats are shown in table 1.5 Data format5.1Digital active line and digital line blankingconsist of 10-bit words as defined by the sourceformat document. Data values 000h to 003h and3FC h to 3FF h are excluded.5.2Timing references SAV, EAV, line-number,and CRCs for each of the two parallel data streamsshall be formatted as shown in figure 2 (see 4.3regarding possible modification of source data).5.3Timing reference codes shall be as shown intable 2.5.4Line number data are composed of two words and shall be as shown in table 3.5.5CRC (cyclic redundancy codes) are used to detect errors in the active digital line and the EAV. The error detection code consists of two words determined by the polynomial generator equation:CRC(X) = X 18 + X 5 + X 4 + 1Initial value of the CRC is set to zero. The calculation starts at the first active line word and ends at the final word of the line number, LN1. Two CRCs are calcu-lated, one for luminance data, YCR, and one for color difference data, CCR. CRC data shall be as shown in table 4.5.6Available ancillary data space is defined by the source format. The ancillary data header shall consist of the three words 000h , 3FF h , 3FF h with formatting of the ancillary data packet defined by ANSI/SMPTE 291M. Data values 000h to 003h and 3FC h to 3FF h are excluded from user ancillary data.6 Serial data format6.1The two source format parallel data streams, with EAV and SAV constructed as defined in 5.3 through 5.5, shall be interleaved as shown in figure 3.6.2Interleaved data shall be serialized with the LSB (least significant bit) of each data word transmitted first.7 Channel coding7.1The channel coding scheme shall be scram-bled NRZI (non-return to zero inverted). (See annex A.)7.2The generator polynomial for the scrambled NRZ shall be G 1(X) = X 9 + X 4 + 1. Polarity-free scrambled NRZI sequence data shall be pro-duced by G 2(X) = X + 1.

Specifications at the output of equipment located at other places in an all-serial digital chain are not addressed by this standard.8.1.1The output of the generator shall be measured across a 75-ohm resistive load connected through a 1-m coaxial cable. Figure 4 depicts the m e a s u r e m e n t d i m e n s i o n s f o r a m p l i t u d e, risetime, and overshoot.8.1.2The generator shall have an unbalanced output circuit with a source impedance of 75 ohms and a return loss of at least [15 dB] over a frequency range of 5 MHz to the clock frequencyof the signal being transmitted.8.1.3The peak-to-peak signal amplitude shall be 800 mV ± 10% measured as specified in 8.1.1.8.1.4The dc offset, as defined by the mid-amplitude point of the signal, shall be nominally 0.0 V ± 0.5 V.8.1.5The rise and fall times, determined be-tween the 20% and 80% amplitude points shall be no greater than 270 ps and shall not differ by more than 100 ps.8.1.6Overshoot of the rising and falling edges of the waveform shall not exceed 10% of the amplitude.8.1.7Output amplitude excursions due to sig-nals with a significant dc component occurring for a horizontal line (pathological signals) shall not exceed 50 mV above or below the average peak-to-peak signal envelope. (In effect, this specification defines a minimum output coupling time constant.)8.1.8The jitter in the timing of the transitions of the data signal shall be measured in accordance with SMPTE RP 184. Measurement parametersare defined in SMPTE RP 184 and shall have the values shown in table 5 for compliance with this standard.8.1.9The receiver of the serial interface signal shall present an impedance of 75 ohms with a return loss of at least [15 dB] over a frequency range of 5 MHz to the clock frequency of the signal being transmitted.8.1.10Receivers operating with input cable losses in the range of up to 20 dB at one-half the clock frequency are nominal; however,receivers designed to work with greater or lesser signal attenuation are acceptable.8.1.11When connected to a line driver operating at the lower limit of voltage permitted by 8.1.3,the receiver must sense correctly the binary data in the presence of the superimposed interfering signal at the following levels:dc ± 2.5 V Below 5 kHz < 2.5 V p-p 5 kHz to 27 MHz < 100 mV p-p Above 27 MHz < 40 mV p-pB110 Hz Timing jitter lower band edge B2100 kHzAlignment jitter lower band edge B3> 1/10 the clock rate Upper band edgeA11 UITiming jitter (Note 1) A2.2 UIAlignment jitter (UI = unit interval) Test signal Color bar test signal(Note 2) n ≠ 10 (preferred)Serial clock divided (Note 3)NOTES1 Designers are cautioned that parallel signals conforming to interconnection standards, such as SMPTE 260M, may contain jitter up to2 ns p-p. Direct conversion of such signals from parallel to serial could result in excessive serial signal jitter.2 Color bars are chosen as a nonstressing test signal for jitter measurements. Use of a stressing signal with long runs of zeros may give misleading results.3 Use of a serial clock divider value of 10 may mask word correlated jitter components.4 See SMPTE RP 184 for definition of terms.Table 5 -- Jitter specificationsANSI/SMPTE 292M-1996Page 6 of 9 pagesNOTE -- Receivers intended for use in environments with minimum interfering signal levels do not need to meet the low frequency interference specifications of 8.1.11(see annex B).8.2 Connector and cable types8.2.1The connector shall have the mechanical characteristics conforming to the 50-ohm BNC type. Mechanical dimensions of the connector may produce either a nominal 50-ohm or nominal 75-ohm impedance and shall be usable at frequencies up to 2.4 GHz based on a return loss of 1.5 GHz that is greater than [15 dB]. However,the electrical characteristics of the connector and its associated interface circuitry shall provide a resistive impedance of 75 ohms.Where a 75-ohm connector is used, its mechani-cal characteristics must reliably interface with the nominal 50-ohm BNC type defined by IEC 169-8.8.2.2Application of this standard does not require a particular type of coax. It is necessary for the frequency response of the coax loss, indecibels, to be approximately proportional to 1/√f from 1 MHz to the clock frequency of the signal being transmitted to ensure correct opera-tion of automatic cable equalizers over moderate to maximum lengths.8.2.3Return loss of the correctly terminated transmission line shall be greater than 15 dB over a frequency range of 5 MHz to the clock frequency of the signal being transmitted.9 Optical fiber interfaceThe interface consists of one transmitter and one receiver in a point-to-point connection.9.1Source characteristics shall be as shown in table 6.9.2Optical fiber characteristics shall be as shown in table 7.9.3Receiver characteristics shall be as shown in table 8.Optical wavelength1310 nm ± 40 nm Maximum spectral line width between half-power points 10 nm Output power maximum -- 7.5 dBm Output power minimum -- 12 dBmRise and fall times < 270 ps (20% to 80%) Extinction ratio 5:1 min, 30:1 max Jitter[0.2 UI] Maximum reflected power4%NOTES1 Power is average power measured with an average-reading power meter.2 Rise and fall times in the electrical domain must meet the requirements of 8.1.5.Table 6 -- Optical source characteristicsANSI/SMPTE 292M-1996Page 7 of 9 pagesAnnex A (informative) Channel codeWhen scrambled NRZI channel coding is applied to certain video signals (informally called pathological signals), repeated long strings of 19 or 20 zeros may occur during the period of one horizontal television line. A stressing test signal (SDI checkfield, SMPTE RP 178) that produces this effect has been defined for 525- and 625-line component digital systems conforming to ANSI/SMPTE 259M. An equivalent test signal is being developed by SMPTE for the serial HDTV system defined in this standard. Additional SMPTE work is in process to recommend methods that may be used to avoid the occurrence of patho-logical signals in normal television operations.Annex B (informative) Receiver typeReceivers conforming to the specifications of 8.1.11 should be labeled ‘‘Type A.’’ Receivers that may not conform to the specifications of 8.1.11 should be labeled ‘‘Type B.’’Annex C (informative) BibliographyANSI/SMPTE 259M-1993, Television ---- 10-Bit 4:2:2 Component and 4f sc NTSC Composite Digital Signals ----Serial Digital Interface SMPTE RP 178-1996, Serial Digital Interface Checkfield for 10-Bit 4:2:2 Component and 4f sc Composite Digital SignalsANSI/SMPTE 292M-1996Page 9 of 9 pages。

SMPTE标准最新信息

SMPTE标准最新信息电影电视工程师协会（sMPTE）于2014年12月举行技术委员会（TC）季会，SMPTE 9个技术委员会和12个小组聚会加利福尼亚伯班克的迪士尼影城。

来自全世界逾100位SMPTE会员与会，而相同数量的会员远程参与。

这些技术委员会会议产生了许多显著的进展。

会议亮点：高动态范围（HDR）视频项目由于意识到超越HDTV的下一步必须在像素数之外取得进展，HDR主题得到了重视。

对如色域、显示动态范围、帧率和电光传递函数这样的参赛的改进都有助于改善证明推出新服务是有理由的观看体验。

SMPTE现在有一个编写HDR生态系统报告的研究小组（SG），并且有一新项目定义HDR和更广色域图像彩色转换的动态元数据。

两个SMPTE HDR项目最近公布了两个新标准：“标准（sT）2084――母带制作参考显示器高动态范围电光传递函数”和“ST 2086――支持高亮度和广色域图像的母带制作显示器彩色量”。

该标准集的第三个文件“ST 2080――高亮度和广色域图像色差”现正在制定中。

高帧率（HFR）项目从这些SMPTE会议出现一个将制定规定HFR时间地址及其在辅助数据空间内的数据结构之标准的新项目。

此标准将扩充到覆盖最高960fps的帧率。

视频压缩（VC）标准SMPTE标准化了5个VC标准：VC-1到VC-5。

当前的VC标准工作包括以下：一制定一系列定义VC-5压缩系统（从一种GoPro系统发展而来）的文件。

此系列文件的两部分已经公布，还有两个即将公布。

当前工作已转到一个定义素材交换格式（MxF）通用容器内VC-5映射的标准。

此系列的3个附加文件已有计划。

通过修tST 2019-1以及在操作规程建议（RP）2019-2内包含一致性测试新位模式，向VC-3功能增加“图像分辨率独立性”。

增加的这些内容向后兼容，当前的功能都不弃用。

这是一个新推出的项目，等待形成一个起草小组。

此项目倡议者解释该修正将通过对12位、推荐（Rec）的ITU-R BT.2020彩色空间的支持，允许从1×1到16384×16384的像素分辨率。

SMPTE标准更新

SMPTE标准更新作者：来源：《电影中国》2015年第08期巴黎TC会议的一些重要内容：“更好的像素”项目人们越来越认识到，超高清电视下一步需要改善的不仅仅是像素数。

改进参数包括色域、显示的动态范围、帧速率和电光特性等等，这些都有助于提高观看体验，从而启动新的服务。

高动态范围（HDR）/宽色域（WCG）/电光传递函数（EOTF）SMPTE有一个研究组（SG），其正在编制HDR生态系统的报告，并计划及时完成SMPTE 2015年度技术研讨会暨展览会（SMPTE2015）。

SMPTE有另一个项目定义动态元数据，针对高亮度和广色域图像的色量转换。

成套文档准备好了，组成部分包括核心部件、系统排列和载体，以及四个或更多记录个人应用的方案。

最近发布的三个SMPTE HDR/ WCG：·ST2084 - 母带制作参考显示器高动态范围电光传递函数·ST2086 - 支持高亮度和广色域图像的母带制作显示器彩色量·ST2085 - 针对高亮度和广色域图像的色分差更高的帧率（HFR）100和120 fps已增加到SMPTE的ST2036-1 UHDTV标准中。

相关传输文件也被引入，以应付额外的带宽需求。

项目延伸SMPTE ST 12时间码，涵盖HFR进展顺利。

互操作母带格式（IMF）预期全球的专业应用，IMF基于文件的框架设计，代表媒体内容高质量的最终版本，可跨多渠道，包括广播和互联网进行分发。

在过去的四年中，该工作组（WG）一直在开发一套大型文档，界定控制那些基于文件的元素，这些元素可用于创建下游分发，可使用多种组合的播放列表。

共有11个 IMF文档公布。

该组织还在进行的工作包括中间层电影格式，Sample Material Interchange （SMI）组织已经举办IMF兼容性测试。

有人提议在本次会议上新一轮的IMF项目需长期存档。

针对专业广播环境的基于网络的同步两个定义在数据网络上发送同步数据包的文件在四月发布。
