CEA-861-D标准文件

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. CEA-861-D标准文件是消费电子协会(CEA)制定的一种针对未压缩数字接口的高清电视（DTV）配置文件。这个标准由CEA的R4.8DTV接口子委员会开发，目的是规范消费者电子设备如数字电视、数字有线、卫星或地面机顶盒（STBs）以及相关外设如DVD播放器/录像机等之间的未压缩数字接口的使用。CEA-861-D取代了之前的CEA-861-C标准。 该标准适用于各种标准的高清数字物理接口，包括数字视觉接口（DVI）1.0、开放低压差分信号显示接口（LDI）和高清晰度多媒体接口（HDMI）规范。CEA-861-D定义了视频格式和波形、色度学和量化、压缩与未压缩音频、线性脉冲编码调制（LPCM）音频的传输、辅助数据的承载，以及视频电子标准协会（VESA）增强型扩展显示识别数据标准（E-EDID）的实现。E-EDID是接收设备用于声明显示能力及特性的标准。 CEA-861-D强烈建议实施高带宽数字内容保护（HDCP）技术，这是由数字内容保护公司（DCP）定义的内容保护方法，以确保与47 C.F.R. § 76.602和47 C.F.R. §76.640授权的数字有线STBs兼容。HDCP允许在家庭网络中从其他视频源观看高价值内容。 此标准的实施旨在消除制造商和购买者之间的误解，促进互换性和产品改进，并帮助购买者迅速选择并获取适合其特定需求的产品。CEA标准并不阻止其成员或非成员制造或销售不遵循这些标准的产品，同时，这些标准也可供CEA成员以外的个人或公司在国内外自愿使用。 需要注意的是，遵循此标准可能涉及使用受专利权保护的发明。CEA发布标准时不承担对任何专利所有者的责任，也不对采用标准的各方承担任何义务。不过，专利持有人已提交愿意根据这些权利授予许可的声明。这表明，虽然标准的发布不涉及对相关专利权有效性的立场，但使用者应意识到可能存在的专利问题，并自行处理与之相关的许可事宜。
