6.2 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
：
CVBS 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 ascomponent 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 rate of 1.485 Gbit/s.
●
3G-SDI
: standardized in SMPTE 424M, consists of a single 2.970 Gbit/s serial link that allows replacing
dual link HD-SDI.
●
6G-SDI:
s
tandardized in SMPTE ST-2081 released in 2015, 6Gbit/s bitrate and able to support
2160p@30.
●
12G-SDI
:standardized in SMPTE ST-2082 released in 2015, 12Gbit/s bitrate and able to support
2160p@60.
●
U-SDI
:
Technology for transmitting large-volume 8K signals over a single cable. a signal interface called
the ultra high definition signal/data interface (U-SDI) for transmitting 4K and 8K signals using a single
optical cable. The interface was standardized as the SMPTE ST 2036-4.
