VESA,EIA,CEA,SMPTE,ITU-R组织之间有什么联系？
比如720P格式，EIA-CEA-861-E和SMPTE 296M中Timing时序内容是相同的、不冲突的，但两者有什么本质的区别？
到底是谁制定了视频标准？他们到底都在干嘛？

假如需要读取HDMI接口电视的EDID，那么应该以哪个文档为标准？

This standard was developed under the auspices of the Consumer Electronics Association (CEA) R4.8 DTV Interface Subcommittee. CEA-861-D supersedes CEA-861-C. CEA-861-D 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 source or sink devices. CEA-861-D is applicable to a variety of standard DTV-related high-speed digital physical interfaces - such as Digital Visual Interface (DVI) 1.0 [3], Open LVDS Display Interface (LDI) [7], and High-Definition Multimedia Interface (HDMI) [29] 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 (LPCM), 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 sink devices to declare display capabilities and characteristics. CEA-861-D adopters are strongly encouraged to implement High-bandwidth Digital Content Protection (HDCP) [2] content protection defined by the Digital Content Protection (DCP), LLC) method, in order to be compatible with digital cable STBs as authorized by 47 C.F.R. § 76.602 [27] and 47 C.F.R. §76.640 [28]. HDCP [29] permits viewing of high-value content that may be available from other video sources in a home network.
