Archive eXchange Format (AXF) – Part 1: Structure & Semantics

Published by: 2017-03-01 / 2017-03-01
This standard is Part 1 of a series of documents that specify a general-purpose format for the storage and/or communication of information in bulk form. The format is named the Archive eXchange Format (AXF). The format described is intended both for interchange between systems and to serve as a native format within systems.

This standard identifies two major categories of data storage media and specifies the basic structures of data stored on those Storage Media Types. It specifies a number of structural elements for use in constructing the appropriate structures for use on each of the Storage Media Types. It defines the semantics of data contained within fields specified for use in the structural elements. The structural elements themselves are documents coded in the eXtensible Markup Language (XML), and this document defines an XML Schema Description (XSD) file for use in formulating the XML documents to be used for the structural elements of AXF Objects.

Interoperable Master Format – Overview for the SMPTE ST 2067 Document Suite

Published by: 2017-02-01 / 2017-02-01 / 3 pages
The IMF is a file-based framework for the exchange and processing of multiple content versions (airline edits, special edition, languages…) of the same high-quality finished work (feature, episode, trailer, advertisement, etc.) destined for distribution channels worldwide. Specialization of the IMF Framework designed to meet the requirements of specific domains is achieved through the definition of IMF Applications.

Ruggedized Fiber-Optic Connectors for HDTV and UHDTV SDI

Published by: 2017-01-06 / 2017-01-06 / 37 pages
This document specifies ruggedized fiber-optic connectors based on standardized fiber-optic connectors, intended for use in HDTV and UHDTV broadcasting and video equipment where robust and reliable solutions are required.

The connectors are intended to be used for optical fiber systems such as defined in SMPTE ST 297-1, SMPTE ST 435-3 and SMPTE ST 2036-3.

This standard defines dimensional requirements related to reference planes of the underlying connector interfaces as standardized in IEC 61754-7 and IEC 61754-20. Furthermore structural and performance requirements are included considering optical and mechanical specifications.

Multi-Link and Multi-Channel 1.5G, 3G, 6G and 12G-SDI Using CWDM

Published by: 2017-01-06 / 2017-01-06 / 15 pages
This standard defines the transport of Multi-Link (ML) or Multi-Channel (MC) SDI data streams over a single fiber using Coarse Wavelength Division Multiplexing (CWDM).

Specifically, this standard specifies a CWDM optical interface for Multi-Link 12G-SDI, Multi-Link 6G-SDI, Multi-Link 3G-SDI and Multi-Link 1.5G-SDI, as well as Multi-Channel 12G-SDI, 6G-SDI, 3G-SDI and/or 1.5G-SDI.

To conform to this standard, It is not necessary for implementations to include support for both Multi-Link and Multi-Channel modes, nor is it necessary to support all interface data rates defined in Table 1. Implementers should indicate supported interface rates and operating modes in commercial publications.

D-Cinema Operations – Key Delivery Message

Published by: 2017-01-12 / 2017-01-12 / 18 pages
This specification defines a “Key Delivery Message” (KDM) for use in Digital Cinema (D-Cinema) systems.
The KDM has been designed to deliver security parameters and usage rights between D-Cinema content
processing centers (e.g. from post production to distribution, or from distribution to exhibition). The KDM
carries fundamentally three information types:

  • Content keys for a specified Composition Play List (CPL).
  • Content key parameters — primarily the permitted key usage date/time window.
  • The Trusted Device List (TDL) which identifies equipment permitted to use the content keys.

The KDM is based on the D-Cinema generic Extra-Theater Message (ETM) format [ETM]. It uses XML to
represent the information about the content decryption keys and TDLs, and provides security using
standardized XML encryption and signature primitives. The KDM message uses X.509 digital certificates,
specified in [D-Cinema Digital Certificate], to provide authentication and trust.

D-Cinema Operations – Digital Certificate

Published by: 2017-01-12 / 2017-01-12 / 21 pages
This standard presents a specification for Digital Certificates. The standard defines the Digital Certificate format and associated processing rules in sufficient detail to enable vendors to develop and implement interoperable security solutions.

The Digital Certificate standard is based on a constrained form of the X.509v3 [X.509] format and processing rules. Only the most widely supported features of X.509v3 are used in order to give vendors a large selection of X.509v3 development toolkits and certificate issuing products. The constraints also avoid the complexity and ambiguity that often occurs in systems that use X.509v3 certificates.

In the D-Cinema environment, certificates have these primary applications:

  • Establishing identity of security devices
  • Supporting secure communications at the network layer (e.g. TLS) or application-messaging layer (e.g., Extra Theater Messages [ETM])
  • Authentication and integrity requirements for Composition Play Lists (CPL) and Packing Lists (PL)

Dynamic Metadata for Color Volume Transform – KLV Encoding and MXF Mapping

Published by: 2017-01-06 / 2017-01-06 / 26 pages
The SMPTE ST 2094 suite of documents defines metadata for use in color volume transforms of content.

SMPTE ST 2094-2 specifies Key-Length-Value (KLV) representations of metadata sets defined in SMPTE ST 2094-10, SMPTE ST 2094-20, SMPTE ST 2094-30, and SMPTE ST 2094-40.

SMPTE ST 2094-2 specifies frame-based mapping of KLV-encoded SMPTE ST 2094 metadata sets into the MXF generic container. SMPTE ST 2094-2 specifies the key and value fields of the essence elements, the essence container label and the essence descriptor.

Essence-independent IP Live Networked Media Transport

Published by: 2016-10-11 / 2016-10-11 / 22 pages
Introduction

Although network systems have become common in file-based applications, until recently it has been difficult to apply networking technologies to live production applications in which there is a strong requirement for real-time processing.

However, with the continuing rapid evolution of networking technologies, there is now a trend towards the use of networked systems for live production applications.

This RDD describes an IP-based transport mechanism (referred to hereafter as `IP mapping’) intended mainly for live production applications.

1 Scope

This RDD defines the IP mapping which includes the following main characteristics:

1. Essence-independent mapping

Each essence (video, audio and ancillary data) can be dealt with independently.

2. Packet protection using FEC and/or hitless failover

Appropriate protection can be chosen according to application requirements.

3. Frame-boundary-aware mapping for both essence and FEC

Frame accurate processing can be performed in both essence and FEC.

4. Support for up to 4K uncompressed and compressed video

Either uncompressed video or compressed video can be chosen up to 4K video seamlessly according to
application requirements.
