Foreword

SMPTE (the Society of Motion Picture and Television Engineers) is an internationally-recognized standards

developing organization. Headquartered and incorporated in the United States of America, SMPTE has

members in over 80 countries on six continents. SMPTE’s Engineering Documents, including Standards,

Recommended Practices, and Engineering Guidelines, are prepared by SMPTE’s Technology Committees.

Participation in these Committees is open to all with a bona fide interest in their work. SMPTE cooperates

closely with other standards-developing organizations, including ISO, IEC and ITU.

SMPTE Engineering Documents are drafted in accordance with the rules given in its Standards Operation

Manual.

SMPTE ST 2082-1 was prepared by Technology Committee 32NF.

Intellectual Property

At the time of publication no notice had been received by SMPTE claiming patent rights essential to the

implementation of this Standard. However, attention is drawn to the possibility that some of the elements of

this document may be the subject of patent rights. SMPTE shall not be held responsible for identifying any

or all such patent rights.

Introduction

This section is entirely informative and does not form an integral part of this Engineering Document.

SMPTE ST 2082-1 defines a bit-serial data interface for the transport of 12 Gb/s [nominal] component

digital signals or packetized data. The mapping of various source image formats to the bit-serial data

structure defined here in this document are described in additional SMPTE ST 2082 document parts.

SMPTE ST 2082-0 contains an informative roadmap for the 12 Gb/s Signal/Data Serial Interfaces.

End users are cautioned that they should work with Serial Digital Interface equipment vendors to ensure

the electrical and mechanical capabilities of cables and connectors — whether existing or new — in

support of this interface meet their requirements.

1 Scope

This standard describes the electrical and physical characteristics of a 12G-SDI coaxial cable interface

suitable for applications where the signal loss does not exceed an amount specified by the receiver

manufacturer. Typical loss amounts would be in the range of up to 40 dB at one-half the clock frequency.

2 Conformance Notation

Normative text is text that describes elements of the design that are indispensable or contains the

conformance language keywords: "shall", "should", or "may". Informative text is text that is potentially

helpful to the user, but not indispensable, and can be removed, changed, or added editorially without

affecting interoperability. Informative text does not contain any conformance keywords.

All text in this document is, by default, normative, except: the Introduction, any section explicitly labeled as

"Informative" or individual paragraphs that start with "Note:”

The keywords "shall" and "shall not" indicate requirements strictly to be followed in order to conform to the

document and from which no deviation is permitted.

The keywords, "should" and "should not" indicate that, among several possibilities, one is recommended as

particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred

but not necessarily required; or that (in the negative form) a certain possibility or course of action is

deprecated but not prohibited.

The keywords "may" and "need not" indicate courses of action permissible within the limits of the document.

The keyword “reserved” indicates a provision that is not defined at this time, shall not be used, and may be

defined in the future. The keyword “forbidden” indicates “reserved” and in addition indicates that the

provision will never be defined in the future.

A conformant implementation according to this document is one that includes all mandatory provisions

("shall") and, if implemented, all recommended provisions ("should") as described. A conformant

implementation need not implement optional provisions ("may") and need not implement them as described.

Unless otherwise specified, the order of precedence of the types of normative information in this document

shall be as follows: Normative prose shall be the authoritative definition; Tables shall be next; followed by

formal languages; then figures; and then any other language forms.

3 Normative References

The following standards contain provisions that, through reference in this text, constitute provisions of this

standard. At the time of publication, the editions indicated were valid. All standards are subject to revision,

and parties to agreements based on this standard are encouraged to investigate the possibility of applying

the most recent edition of the standards indicated below.
