This standard defines the electrical and physical representation of a television color reference pattern. It also specifies colorimetry, geometry, and related parameters.

This standard defines a family of progressive image sampling systems for the representation of stationary or moving two-dimensional images sampled temporally at a constant frame rate and having an image format of 1280 pixels by 720 lines and an aspect ratio of 16:9.

(1.1) This standard defines the digital representation of stationary or moving two-dimensional images for television production. The representation is sampled linearly in the spatial domain and sampled temporally at a constant frame rate.

This standard defines two alternatives for bit-serial interfaces for the 720 × 483 active line at 59.94-Hz progressive scan digital signal for production, defined in ANSI/SMPTE 293M. Interfaces for coaxial cable are defined, each having a high degree of commonality with interfaces operating in accordance with ANSI/SMPTE 259M (BTA Report T-1004 contains additional information regarding the application of these interfaces in practical systems): (a) Dual-link interface (4:2:2P): Each link operating at 270 Mb/s, in which the active data in the Y', C'B, C'R format (equivalent to 8:4:4) are transparently divided, line sequentially, into two data streams, each equivalent to the 4:2:2 component signal of ANSI/SMPTE 259M. (b) Single-link interface (4:2:0P): Operating at 360 Mb/s, in which the active data representing the colordifference components in the Y', C'B, C'R format (equivalent to 8:4:4) are field quincunx down-converted by a factor of two, prior to reformatting with the full luminance data, into a single data stream equivalent to the component signal of ANSI/SMPTE 259M (but at a higher data rate, conceptually 8:4:0). — NOTES (1) The data rate of 360 Mb/s is related by a factor of 4/3 to the basic data rate of 270 Mb/s specified for 4:2:2 component signals in ANSI/SMPTE 259M. (2) The down-conversion of the color-difference components results in an equivalent spatial sampling grid for each that is similar in the horizontal and vertical dimension. (3) The term line in this standard refers to the digital line in the 483-line frame raster as described in ANSI/SMPTE 293M.

This standard defines a family of raster scanning systems for the representation of stationary or moving two-dimensional images sampled temporally at a constant frame rate and having an image format of 1920 × 1080 and an aspect ratio of 16:9 as given in table 1. This standard specifies: – R'G'B' color encoding; – R'G'B' analog and digital interfaces; – Y'P'BP'R color encoding and analog interface; and – Y'C'BC'R color encoding and digital interface. — An auxiliary component A may optionally accompany Y'C'BC'R; this interface is denoted Y'C'BC'RA.

This standard defines a means of transporting stereoscopic images (Left eye and Right eye images) using an interface consisting of two streams based on the SMPTE ST 292-1 data structure. The Left eye images are carried on one stream of the interface and the Right eye images are carried on the other stream. The stereoscopic image formats to be transported using this standard are the 4:2:2/10-bit image formats defined by SMPTE ST 274, SMPTE ST 2048-2 and SMPTE ST 296, which can be transported by a single SMPTE ST 292-1 serial interface. Audio and other associated ancillary data may also be transported. This standard also defines a payload identifier.

The SMPTE 292 suite of documents defines the mapping of various source image formats onto serial digital interfaces operating at a nominal rate of 1.5 Gb/s. This informative “roadmap” describes the documents in the 292 suite.

This standard specifies the digital representation of the signal parameters of the 1125/60 high-definition production system as given in their analog form by ANSI/SMPTE 240M. — This standard also specifies the signal format and the mechanical and electrical characteristics of the bit-parallel digital interface for the interconnection of digital television equipment operating in the 1125/60 high-definition production system.

This standard defines the component analog video interface for studio applications using three primary color signals carried on parallel channels for the interconnection of television equipment. The signals carried across the interface have a typical scanning structure of 525 lines, 59.94 fields/s, 2:1 interlace, and 4:3 or 16:9 aspect ratio. The signals have a vertical blanking interval that is divided into an active line period and a horizontal blanking interval. Signal characteristics are defined by a gamma-corrected set of red, green, and blue R'G'B' (hereafter defined as RGB) primary video signals. — In addition to general interconnection of television equipment at the RGB component analog level of operation, the signals defined by this standard are suitable as inputs to analog-to-digital conversion systems in compliance with ANSI/SMPTE 125M and ANSI/SMPTE 267M or as inputs to NTSC composite encoders in compliance with ANSI/SMPTE 170M. — The three-channel interface defined by this standard (sync on green) is the preferred implementation. Some applications may require a four-channel interface (with sync carried separately). Such an implementation is described in annex A.

(1.1) This standard describes a bit-parallel composite video digital interface for systems operating according to the 525-line, 59.94-Hz NTSC standard, as described by SMPTE 170M, sampled at four times color subcarrier frequency. Sampling parameters for the digital representation of encoded video signals, the relationship between sampling phase and color subcarrier, and the digital levels of the video signal are defined. (1.2) This standard has application for use with shielded twisted 12-pair cable of conventional design over distances up to 50 m, without transmission equalization or any special equalization of the receiver. Longer cable lengths may be used, but with rapidly increasing requirement for care in the cable selection and possible receiver equalization or the use of active repeaters or both. (1.3) Digital composite video signals, as defined by this standard, are the signals conveyed by the composite implementation of the serial digital interface. It should be noted that additional information to that described by this standard is also carried by the serial digital interface. — The serial digital interface is the preferred method for the interconnection of composite digital equipments when cable lengths exceed 50 m.
