GOST R 56152-2014 PDF

Full title and description

GOST R 56152-2014 — Digital Video Broadcasting. Modulator Interface (T2‑MI) for a second generation digital terrestrial television broadcasting system (DVB‑T2). Basic parameters. The standard specifies the T2‑MI packet formats, protocol stack, timing/timestamping, encapsulation (MPEG‑2 TS and IP/RTP) and essential operational parameters required by a DVB‑T2 modulator.

Abstract

This national GOST R standard defines the interface between a T2‑gateway (or other equipment generating T2 data) and a DVB‑T2 modulator — commonly called T2‑MI. It covers packet structures, required packet types (base frames, L1 signalling, timestamps, FEF, auxiliary streams), encapsulation into MPEG‑2 TS and options for carriage over IP, and timing requirements to support MFN/SFN operation. The content aligns with the ETSI T2‑MI specification used in DVB‑T2 deployments.

Scope

The standard specifies the basic parameters of the T2‑MI between a T2 gateway (or other source of T2 data) and a DVB‑T2 modulator. It defines T2‑MI packet types and formats, ordering and timing constraints (so packets arrive at the modulator with required lead times), the T2‑MIP transport packet format, rules for encapsulation into MPEG‑2 Transport Streams and for multicast/IP carriage, and provisions for SFN synchronization using DVB‑T2 timestamps. It is intended to ensure interoperable implementation of T2‑MI for DVB‑T2 transmit chains.

Key topics and requirements

• Definition of the T2‑MI protocol stack and packet formats (header, payload, padding, CRC) and the list of packet types (base frame, L1 current/upcoming, timestamp, auxiliary streams, FEF, individual addressing, etc.).
• Timing and arrival constraints so T2‑MI packets reach the modulator with defined lead times relative to T2 frame transmission (supports MFN/SFN operation and accurate emission timing).
• Encapsulation rules: packaging T2‑MI packets into MPEG‑2 TS (data‑piping) and optional encapsulation for carriage over IP/RTP; specified PID and transport packet details for T2‑MIP.
• Fields and semantics for L1 signalling, DVB‑T2 timestamps (including null timestamp rules), PLP identification, aux stream IQ vectors, and FEF handling.
• Individual transmitter addressing and functions for per‑transmitter configuration (time/frequency offsets, power, cell ID, private data, DVB‑T2 specific addressing functions).

Typical use and users

Primary users are broadcast system designers, manufacturers of DVB‑T2 modulators and gateways, network integrators deploying MFN/SFN TV networks, and national/regional broadcast operators and regulators who require interoperable modulator interfaces. Equipment testing labs and software developers implementing T2‑MI generators or ingesters also use this standard as a technical reference.

Related standards

The GOST R 56152‑2014 document is aligned with and references the ETSI T2‑MI specification (ETSI TS 102 773) and related DVB/DVB‑T2 normative documents (e.g., baseband frame definitions and MPEG‑TS carriage rules). It also lists national GOST references used in the digital broadcasting family (examples cited in the national document include GOST R 52210‑2004, GOST R 52591‑2006 and GOST R 53528‑2009).
