A DTV Profile for Uncompressed High Speed Digital Interfaces
|Publication Date:||1 July 2006|
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 , Open LVDS Display Interface (LDI) , and High-Definition Multimedia Interface (HDMI)  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) , 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)  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  and 47 C.F.R. §76.640 . HDCP  permits viewing of high-value content that may be available from other video sources in a home network.
