RGB S

RGB signal with composite sync. which is transmitted by a 4 wires coaxial cable. Sometimes called RGB sync.

RS232

A worldwide serial digital interface standard used for the remote control of many devices usually used in the Audio and Video Industrial, fields.

see UV.

S
S/PDIF

Sony/Philips Digital Interconnect Format. S/PDIF is a digital audio interconnect used in consumer audio equipment over relatively short distances. The signal is transmitted over either a coaxial cable with RCA connectors or a fiber optic cable with TOSLINK connectors. S/PDIF interconnects components in home theaters and other digital high fidelity systems. S/PDIF is based on the professional AES3 interconnect standard. S/PDIF can carry two channels of PCM audio or a multi-channel compressed surround sound format such as Dolby Digital or DTS.

SCALER

Device that changes the effective resolution of a TV/Video image into a native match standard high-resolution computer format such as WUXGA+, UXGA, S.XGA, XGA, SVGA or VGA. It’s a “combination” of a Line Doubler, Tripler & Quadrupler. Usually dedicated to DATA displays and projectors, to improve the resolution, increase the brightness and to decrease the flickering of the picture.

SCAN CONVERTER

Device that converts a Computer scan rate into a TV/Video signal allowing computer images to be displayed or recorded on any video support. The Horizontal and the Vertical scanning rate are changed.

SCAN DOUBLER

see Line Doubler.

SDI

Serial Digital Interface, especially present in Broadcast Scan Converters with a Digital Output.

SDTV

Standard Definition TV (15 kHz), in opposition with HDTV. It means analog or digital signals.

SEAMLESS

Term used to define clean, fast switching between 2 sources. This new way of switching operates without any loss of synchronization and is glitch-free on the display. See SEAMLESS SWITCHER ® section.

SECAM

SEquentiel Couleur Avec Mémoire (Sequential Color With Memory). Television standard used in France, Africa, Russia and Eastern Europe. Like the PAL system, a SECAM picture consists of 625 horizontal lines refreshed at 50 Hz interlaced, but the color is coded in a different way (Frequency modulation, 1 line U & 1 line V).

SFP

The small form-factor pluggable (SFP) or Mini-GBIC is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. It interfaces a network device mother board to a fiber optic or copper networking cable. It is a popular industry format supported by many network component vendors.

SEGMENTED FRAME

HDTV standard proposed by SONY®: 1080 sF 24*, where the 1080 progressive lines at 24 frames/sec are interlaced in 2x540 at 48 fields/sec. (In fact, it’s more exactly 23,97 and 47,95 Hz for Color).

SHARPNESS

Definition of a picture's edges.

SMPTE 424M

This HD standard defines a full bandwidth, 4:4:4 RGB color space and bandwidth up to 2.97 Gbps on a single coaxial cable. SMPTE 424M is known as 3G-SDI, a term used to describe 2.970 Gigabits per second digital video over a single-link coaxial cable. 3G-SDI is capable of supporting HDTV 1080p video at 50 or 60 frames per second.
