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.

6 Gb/s Signal/Data Serial Interface – Electrical – Amendment 1

Published by: 2016-10-17 / 2016-10-17 / 2 pages
The purpose of this amendment is to change the Timing Jitter specification for the interface to correctly reflect the requirements and capabilities of 6G-SDI equipment. It also corrects arithmetic errors in the alignment jitter specification where the time representation of 0.3UI is inaccurately calculated in the standard.
