《CTA-861-G-FINAL-revised-2017（EDID）.pdf》是一份视频图像标准说明文档，包括了EDID的相关说明。该文档是由CTA（消费技术协会）发布的，旨在为未压缩高速数字接口（DTV）提供一个配置文件。此通告主要是向用户、实施者和参考CTA‐861的标准制定组织发送的，通知他们最新修订的CTA‐861‐G版本。通告中提到，之所以向已经获取CTA‐861‐E、ANSI/CTA‐861‐F或ANSI/CTA‐861‐G副本的人发送该通知，是因为这些文件已经从原版中删除了对Adobe的引用。这个变动是根据一家公司的要求进行的，该公司认为其商标被使用了。虽然通告中没有具体提及该公司的名称，但可以推测该公司与Adobe有某种关联。 CTA-861是一项关键的视频图像标准，提供了一种在数字设备之间传输高质量视频和音频的方法。该标准定义了视频和音频数据格式、时序参数以及相关的控制信号。通过遵循这个标准，不同厂家生产的设备可以实现互操作性，从而实现高品质的数字视频和音频传输。在原始版本中，CTA‐861中包含了与Adobe有关的引用。例如，它可能提到了使用Adobe的工具或技术来处理相关的视频和图像文件。然而，根据该公司的要求，这些引用已经从修订版本中删除，并且通告中强调了这一点。这样的变动可能是因为版权或商标问题。一些公司可能会要求删除对其商标的引用，以保护其品牌权益。此外，通过从标准中删除对特定厂商的引用，可以提高标准的中立性和客观性，以确保不会对任何供应商造成偏好。对于那些已经获取了CTA‐861‐E、ANSI/CTA‐861‐F或ANSI/CTA‐861‐G副本的用户来说，他们需要注意这些修订的变化。特别是那些与Adobe相关的工具或技术在其业务中发挥重要作用的用户，可能需要重新考虑其设备配置和操作流程。总之，该通告通知了接收者最新修订的CTA‐861‐G版本。这个通告解释了为什么从原始版本中删除了对Adobe的引用，并强调了这个变动的原因。对于那些与Adobe相关的用户来说，这可能导致一些设备配置和操作流程上的变化。该通告强调了遵循最新标准的重要性，以实现高质量的数字视频和音频传输。

CTA-861-G

A DTV Profile for Uncompressed High Speed Digital Interfaces

1 Scope

CTA-861 establishes protocols, requirements, and recommendations for the utilization of uncompressed

digital interfaces by consumer electronics devices such as Digital Televisions (DTVs), digital cable,

satellite or terrestrial set-top boxes (STBs), and related peripheral devices including, but not limited to

DVD players/recorders, and other related Sources or Sinks.

CTA-861 is applicable to a variety of standard DTV-related high-speed digital physical interfaces - such

as Digital Visual Interface (DVI) 1.0 [4], Open LVDS Display Interface (LDI) [8], and High-Definition

Multimedia Interface (HDMI) [71] specifications. Protocols, requirements, and recommendations that are

defined include Video Formats and waveforms; colorimetry and quantization; transport of compressed

and uncompressed, as well as Linear Pulse Code Modulation (L-PCM), audio; carriage of auxiliary data;

and implementations of the Video Electronics Standards Association (VESA) Enhanced Extended Display

Identification Data Standard (E-EDID) [9], which is used by Sinks to declare display capabilities and

characteristics.

CTA-861 adopters are strongly encouraged to implement High-bandwidth Digital Content Protection

(HDCP) [3] content protection, defined by the Digital Content Protection, LLC (DCP) method, in order to

be compatible with digital cable STBs as authorized by 47 C.F.R. § 76.602 [69] and 47 C.F.R. §76.640

[70]. HDCP [3] permits viewing of high-value content that may be available from other video Sources in a

home network.

2 General

2.1 References

CTA-861 includes mechanisms that allow a digital video Source (such as a cable, satellite or terrestrial

STB, digital VCR, or DVD player) to supply displayable, baseband, digital video to High Definition

Television (HDTV) devices, as well as peripheral devices such as repeaters, switchers, and recorders, as

defined in CTA Expands Definitions for Digital Television Products [64].
