5.2 Terms & Definitions
●RCA: Connector used primarily in consumer AV equipment for both audio and video. The RCA connector
was developed by the Radio Corporation of America.
● BNC :Stands for Bayonet Neill-Concelman. A cable connector used extensively in television (named for its inventors). A
cylindrical bayonet connector that operates with a twist-locking motion.
●CVBS: C VBS or Composite video, is an analog video signal without audio. Most commonly CVBS is used for
transmission of standard definition signals. In consumer applications the connector is typically RCA type, while in
professional applications the connector is BNC type.
●YPbPr: Used to describe the colour space for progressive-scan. Otherwise known as component video.
●VGA: Video Graphics Array. VGA is an analog signal typically used on earlier computers. The signal is non-interlaced in
modes 1, 2, and 3 and interlaced when using in mode.
●DVI: Digital Visual Interface. The digital video connectivity standard that was developed by DDWG (Digital Display
Work Group). This connection standard offers two different connectors: one with 24 pins that handles digital
video signals only, and one with 29 pins that handles both digital and analog video.
●SDI: Serial Digital Interface. Standard definition video is carried on this 270 Mbps data transfer rate. Video pixels are
characterized with a 10-bit depth and 4:2:2 color quantization. Ancillary data is included on this interface and typically
includes audio or other metadata. Up to sixteen audio channels can be transmitted. Audio is organised into blocks of 4
stereo pairs. Connector is BNC.
●HD-SDI: High-definition serial digital interface (HD-SDI), is standardized in SMPTE 292M this provides a nominal data

Stream Compression 1.2 (DSC), DSC is a "visually lossless" encoding technique with up to a 3:1 compression ratio. Using
DSC with HBR3 transmission rates, DisplayPort 1.4 can support 8K UHD (7680 × 4320) at 60 Hz or 4K UHD (3840 × 2160)
at 120 Hz with 30 bit/px RGB color and HDR. 4K at 60 Hz 30 bit/px RGB/HDR can be achieved without the need for DSC.
●Multi-mode Fiber: Fibers that support many propagation paths or transverse modes are called multi-mode fibers,
generally have a wider core diameter and are used for short-distance communication links and for applications where
high power must be transmitted.
●Single-mode Fiber: Fiber that support a single mode are called single-mode fibers. Single-mode fibers are used for
most communication links longer than 1,000 meters (3,300 ft).
●SFP: Small form-factor pluggable, is a compact, hot-pluggable network interface module used for
both telecommunication and data communications applications.
●Optical Fiber Connector:Terminates the end of an optical fiber, and enables quicker connection and disconnection
than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. 4 most common types
of optical fiber connectors are SC, FC, LC,ST.
●SC: (Subscriber Connector), also known as the square connector was also created by the Japanese company – Nippon
Telegraph and Telephone. SC is a push-pull coupling type of connector and has a 2.5mm diameter. Nowadays, it is used
mostly in single mode fiber optic patch cords, analog, GBIC, and CATV. SC is one of the most popular options, as its
simplicity in design comes along with great durability and affordable prices.
●LC：(Lucent Connector) is a small factor connector (uses only a 1.25mm ferrule diameter) that has a snap coupling
mechanism. Because of its small dimensions, it is the perfect fit for high-density connections, XFP, SFP, and SFP+
transceivers.
●FC: (Ferrule Connector) is a screw type connector with a 2.5mm ferrule. FC is a round shaped threaded fiber optic
connector,mostly used on Datacom, telecom, measurement equipment, single-mode laser.
●ST: (Straight Tip) was invented by AT&T and uses a bayonet mount along with a long spring-loaded ferrule to support
the fiber.
●USB: Universal Serial Bus is a standard that was developed in the mid-1990s that defines cables, connectors and
communication protocols. This technology is designed to allow a connection, communication and power supply for
peripheral devices and computers.
●USB 1.1: Full–Bandwidth USB, specification was the first release to be widely adopted by the consumer market. This
specification allowed for a maximum bandwidth of 12Mbps.
●USB 2.0: Or Hi–Speed USB, specification made many improvements over USB 1.1. The main improvement was an
increase in bandwidth to a maximum of 480Mbps.
