Overview

ISO 26428-19:2011 specifies requirements for serial digital interface (SDI) signal formatting in digital cinema (D-cinema) distribution masters, focusing on additional frame rate levels AFR2 and AFR4. This standard defines how the image pixel structure for these frame rates, as detailed in ISO 26428-11, should be formatted and transmitted over 1.485 Gb/s dual link SDI (SMPTE 372M) and 3 Gb/s SDI (SMPTE 424M) interfaces. By ensuring compatibility and correct formatting, ISO 26428-19:2011 plays a critical role in the digital cinema post-production and distribution process, promoting interoperability across global digital cinema workflows.

Key Topics

SDI Signal Formatting for AFR2 and AFR4: Defines the fixed SDI container size (2048 x 1080 pixel array) for both 25 fps and 30 fps progressive frame rates.

Pixel Structure Conformance: Outlines requirements for arranging image data and padding within the SDI container, ensuring the image center aligns with the SDI container center.

Padding and Data Coding: Specifies use of padding pixels and X’, Y’, Z’ color coding as defined in related standards, with explicit constraints on allowable code values.

Synchronization Sequences: Describes the structure and use of Start of Active Video (SAV) and End of Active Video (EAV) digital synchronizing sequences to ensure valid frame and line identification during transmission.

Progressive Segmented Frame (PsF) System: Includes provisions for transmitting progressive images over interfaces originally designed for interlaced video, facilitating backward compatibility in cinema workflows.

Normative References: Aligns closely with other ISO and SMPTE digital cinema standards to ensure comprehensive coverage of image, audio, and metadata requirements.

Applications

ISO 26428-19:2011 is widely implemented in the digital cinema industry for:

Digital Intermediate and Distribution Mastering: Ensuring D-cinema content is correctly formatted for both 25 fps and 30 fps delivery.

Post-Production Workflows: Standardizing SDI output for DCDM (Digital Cinema Distribution Master) across various mastering, editing, and quality control systems.

Cinema Content Distribution: Facilitating reliable transmission of high-fidelity digital cinema packages (DCPs) within and between studios, post facilities, and cinemas, especially when using diverse SDI-based networks.

Equipment Interoperability: Supporting seamless integration of playback servers, projectors, and display devices that rely on SMPTE 372M or 424M SDI interfaces.

Organizations relying on consistent, high-quality digital cinema distribution workflows benefit from implementing ISO 26428-19:2011 by ensuring equipment compatibility and maintaining image integrity across international markets.
