ISO 26428-9:2009 defines the formatting and constraints of the level 3 image pixel structure as defined in ISO 26428-1, for transmission over the 1,485 Gb/s dual link serial digital interface in accordance with SMPTE 372M or the 3 Gb/s interface in accordance with SMPTE 424M.

Overview

ISO 26428-9:2009 (equivalent to SMPTE 428-9-2008) is part of the D‑Cinema Distribution Master (DCDM) suite. It specifies the level 3 image pixel structure formatting and constraints for transmission over Serial Digital Interface (SDI) links - specifically the 1.485 Gb/s dual‑link SDI (SMPTE 372M) and the single 3 Gb/s SDI (SMPTE 424M). The standard defines how a 2048 × 1080 DCDM image is packed into an SDI container, synchronization signaling, ancillary data use, and constraints on pixel code values and blanking.

Key topics and requirements

SDI container and pixel array

Fixed SDI container sized for a 2048 × 1080 pixel array (DCDM Level 3).
Active image centered in the container; unused pixels are padding and shall be set to 0x010 (black).
Sampling parameters include 24 Hz frame rate and a reference sampling frequency (fs) of 74.25 MHz for the specified mapping.

Pixel coding

Image channels are three parallel data channels X′, Y′, Z′ following the DCDM image pixel structure as defined in SMPTE 428‑1.
Payload shall avoid certain reserved code ranges (the standard prohibits ranges such as 0x000–0x00F and 0xFF0–0xFFF in the payload).
Values outside defined limits in the source signal must be clipped.

Serial line framing and sync

Use of standard SDI digital synchronizing sequences: SAV (Start of Active Video) and EAV (End of Active Video) - each is a 4‑word sequence (all‑ones, two all‑zeros, then a timing word with F/V/H/P bits).
The interface frame contains 1125 total lines, with the 1080 active image lines mapped to lines 42–1121.
Special handling for Progressive Segmented Frame (PsF) systems is specified (line numbering and F/V bit assignment).

Ancillary data (ANC)

ANC packets may be carried in blanking intervals (HANC/VANC) per SMPTE 291M.
ANC words use the 10 most significant bits of the 12‑bit sample (LSB 2 bits set to zero).
Unused blanking intervals shall carry the black codeword (0x010).

Applications and users

Post‑production and digital cinema mastering facilities creating DCDM packages for theatrical distribution.

Manufacturers of SDI encoders/decoders, video servers, routers, and digital cinema playback servers/projectors.

Systems integrators and QA engineers validating SDI transport compliance for D‑cinema workflows.

Broadcast and mastering engineers implementing 2K/2048×1080 DCP (distribution master) ingest/export over SDI.
