S-VHS is an enhancement to regular VHS video tape decks.
S-VHS provides better resolution and less noise than VHS. S-VHS video tape decks support separate luma (Y') and chroma (C) video inputs and outputs, although this is not required. It does, however, improve the quality by not having to continuously merge and then separate the luma and chroma signals.

A) An improved version of the VHS tape format capable of recording better picture resolution (definition). A higher-density tape is required which provides a wider luminance bandwidth, resulting in sharper picture quality (>400 horizontal lines vs. 240 for standard VHS) and improved signal-to-noise ratio. Because the equipment is usually smaller and lighter than 3/4" equipment, it is ideally suited for ENG/EFP applications. b) Super VHS, a consumer videotape format offering horizontal resolution somewhat greater than that offered by NTSC broadcasting but allowing component recording and playback without cross-luminance or cross-color artefacts through a four-pin S-Video connection.

An improved version of the VHS-C tape format capable of recording better picture resolution (definition).

The standard for the way a signal is carried on the cable itself. The industry has settled on a 4-pin mini plug connector.
S-Video does not have any relation to the resolution or refresh rate of the signal. Do not confuse S-Video with S-VHS. S-VHS is a tape/signal standard.
S-Video is a hardware standard that defines the physical cable jacks.
S-Video allows you to bypass the comb philtre in a device. Generally, less processing of the signal results in a better picture. The comb philtre separates the chroma (color) and luma (brightness) components of a video signal into separate parts. This is also called Y/C, where Y represents brightness and C color. When colour and brightness are not separated, when they are combined in the signal, it is called a composite signal. S-Video cables have separate wires for the colour and brightness. That is, they carry a Y/C signal. The best picture comes when the colour and brightness is separate from the source. VCRs record this way, and DSS broadcasts this way too.
Laserdiscs store a composite picture rather than Y/C separated. Even when the signals have been combined at some point on their way to the monitor, different comb philtres perform to different degrees of quality, so one can pick how to connect one’s components to try to use the best comb filter.
Some older sets with S-Video input jacks may actually combine the Y/C in a crude way, making the S-Video input no better than a typical composite signal. Newer sets do not do this.

A set of specifications for multipoint communications and data sharing for PC platforms. T.120 is based on the H.320 broad-based PB platform standard for Personal Teleconferencing.

The T1Q1.5 Video Teleconferencing/Video Telephony (VTC/VT) ANSI Subworking Group (SWG) was formed to draught a performance standard for digital video. Important questions were asked, relating to video digital performance characteristics of video teleconferencing/video telephony: a) Is it possible to measure motion artefacts with VTC/VT digital transport? b) If it can be done by objective measurements, can they be matched to subjective tests? c) Is it possible to correlate the objective measurements of analogue and digital performance specification? The VTC/VT Subworking Group’s goal is to answer these questions. It has become a first step to the process of constructing the performance standard.
