SMPTE’s vertical interval time code (VITC) format standard.
The term VITC, used alone, usually refers to SMPTE-VITC.

American standardizing body. SMPTE 240M is the first SMPTE HDEP standard, calling for 1125 scanning lines, 2:1 interlace, a 16:9 aspect ratio, and 60 fields per second, among other characteristics. It is identical to the HDEP standard approved by ATSC. It need not be SMPTE’s only HDEP standard, however. The Society has current standards for more than ten different videotape recording formats, with more pending. There are indications that members of SMPTE’s WG-HDEP are interested in a progressivelyscanned HDEP system, an evolution of the 1125-line interlace standard.

A consumer version of the AES/EBU digital audio interconnection standard. The format uses a 75-ohm coaxial cable with RCA connectors and has a nominal peak-topeak value of 0.5 V. The frame ordering differs slightly than that of AES/EBU, specifically in the channel status information. Refer to AES/EBU interface.

a) Approaches to the specification of a studio standard, HDTV have been in the context of present operations in 525/59.94 and 625/50: i.e., operations in the studio conform to the specifications for transmission and broadcast. The studio standard with its implication of no systems transform, therefore, might be described also as one of the distribution standards - expected to be one of the inputs to display, and to be evaluated by subjective judgment of the display.
b) As employed by CCIR Rep 801-4 and its annexes, the term studio standard loosely embraces everything from image capture through distribution. To illustrate the interpretation by examples from the document. (a) Sec 1, Introduction: A single standard could be beneficial to program producers as well as broadcasting organizations and viewers. (b) Sec 2, Technical Matters: This entire section is concerned with defining the system by reference to the subjective, visual appraisal of the final display. (c) Annex II, entitled Parameter Values for Signal Generation in HDTV Studios and For International Exchange of HDTV Programs. (d) Sec 1e explains that the advantages of a single HDTV worldwide standard includes lower HDTV equipment costs for broadcasters and viewers, easier exchange of programs and technical information, and encouragement to the ideal of international solutions to common technical problems. These concepts of a studio standard accordingly address only a small part of what the SMPTE Committee on Hybrid Technology considers production.

An ATV scheme proposed by Faroudja. It combines progressive scanning, pre-filtering, pre-combing, image enhancement, and gamma correction at the transmission end with complementary processing and line doubling at the receiver. It is both channel-compatible and receiver-compatible and is one of the few ATV schemes that keep an aspect ratio of 12:9.

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 artifacts through a four-pin S-Video connection.
