This standard was developed under the auspices of the Consumer Electronics Association (CEA) R4.8DTV Interface Subcommittee.CEA-861-D supersedes CEA-861-C.CEA-861-D establishes protocols, requirements, and recommendations for the utilization ofuncompressed 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 notlimited 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 - suchas Digital Visual Interface (DVI) 1.0 [3], Open LVDS Display Interface (LDI) [7], and High-DefinitionMultimedia Interface (HDMI) [29] specifications. Protocols, requirements, and recommendations that aredefined include video formats and waveforms; colorimetry and quantization; transport of compressed anduncompressed, as well as Linear Pulse Code Modulation (LPCM), audio; carriage of auxiliary data; andimplementations of the Video Electronics Standards Association (VESA) Enhanced Extended DisplayIdentification Data Standard (E-EDID) [9], which is used by sink devices to declare display capabilitiesand 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 tobe 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 ahome network.
