DisplayPort
Digital display interface developed by the Video Electronics Standards Association (VESA). This royalty-free interface
is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used
to transmit audio, USB, and other forms of data. VESA designed it to replace VGA, DVI, and FPD-Link. Backward
compatibility to VGA and DVI by using active adapter dongles enables users to use DisplayPort fitted video sources
without replacing existing display devices.
HDCP
High-bandwidth Digital Content Protection is a form of digital copy protection developed by Intel Corporation to prevent
copying of digital audio and video content as it travels across DisplayPort, Digital Visual Interface (DVI), High-Definition
Multimedia Interface (HDMI), Gigabit Video Interface (GVIF), or Unified Display Interface (UDI) connections, even if
such copying would be permitted by fair use laws. The specification is proprietary, and implementing HDCP requires
a license.
3G-SDI
Serial Digital Interface (SDI) is a serial link standardized by ITU-R BT.656 and the Society of Motion Picture and Tele-
vision Engineers (SMPTE). SDI transmits uncompressed digital video over 75-ohm coaxial cable within studios, and
is seen on most professional video infrastructure equipment. The first revision of the standard, SMPTE 259M, was
defined to carry digital representation of analog video such as NTSC and PAL over a serial interface and is more pop-
ularly known as standard-definition (SD) SDI. The data rate required to transmit SD SDI is 270 Mbps. With the advent
of high-definition (HD) video standards such as 1080i and 720p, the interface was scaled to handle higher data rates
of 1.485 Gbps. The 1.485-Gbps serial interface is commonly called the HD SDI interface and is defined by SMPTE
292M, using the same 75-ohm coaxial cable. Studios and other video production facilities have invested heavily on
the hardware infrastructure for coaxial cable and have a vested interest in extending the life of their infrastructure. For-
tunately, SMPTE recently ratified a new standard called SMPTE 424M that doubles the SDI data rates to 2.97 Gbps
using the same 75-ohm coaxial cable. This new standard, also called 3-Gbps (3G)-SDI, enables higher resolution of
picture quality required for 1080p and digital cinema.
HDMI
HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video
data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a com-
patible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for
existing analog video standards.
