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 Television 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 popularly 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. Fortunately, 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 compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a
digital replacement for existing analog video standards.

Trusted Device List (TDL)
The Goal of the TDL is to maintain timely and accurate information on participating auditoriums so that
participating subscribers can obtain information needed to issue KDMs. The TDL has several data sources:
Device manufacturers, Exhibitors, Deployment Entities, Integrators, Service Providers (interacting with
Exhibitors), regional authorities and Support.
Public Key Infrastructure (PKI)
PKI is a framework for creating a secure method for exchanging information based on public key
cryptography. The foundation of a PKI is the certificate authority (
CA
), which issues digital certificates that
authenticate the identity of organizations and individuals over a public system such as the Internet. The
certificates are also used to sign messages, which ensures that messages have not been tampered with.

Key Delivery Message (KDM)
The security key for each movie is delivered in a unique KDM for each digital cinema server. The security key
is encrypted within the KDM, which means that the delivery of a KDM to the wrong server or wrong location
will not work, and thus such errors cannot compromise the security of the movie. The KDM is a small file, and
is typically emailed to the exhibitor. To create the correct set of KDMs for a site requires knowledge of the
digital certificate in the projection system´s media block.
