Standard that defines reference synchronising signals for analogue or digital 525-line systems including recommendations for black burst.
Industry:Software
Standard for digital audio reference levels for digital VTRs. This is being revised into a studio standard.
Industry:Software
Standard for error detection and handling in serial digital component and composite systems.
Industry:Software
Binary time code denoting hours, minutes, seconds, and frames. See also Time Code.
Industry:Software
SMPTE’s vertical interval time code (VITC) format standard.
The term VITC, used alone, usually refers to SMPTE-VITC.

American standardising 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.
Industry:Software
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 judgement 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 programme producers as well as broadcasting organisations 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 programmes 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.
