Catalog Index
A complete index of SMPTE's published ST, RP, EG, OV, and RDD documents, organised into 21 subject-matter families spanning the Society's full history — from 1950s film mechanical standards to 2025's Catena control-plane suite. Document titles are taken directly from SMPTE's own published catalog, with every document detailed in a standalone, self-contained entry.
Document type key:
ST Standard — normative, states criteria necessary for effective interchange
RP Recommended Practice — facilitates implementation
EG Engineering Guideline — informative, no conformance
RDD Registered Disclosure — vendor-submitted, registered not standardised
OV Overview — roadmap for a document suite

SDI — Serial Digital Interface · 108 documents
ℹ
This family spans every SDI generation from the original 1989 SD-SDI standard through the current 12G-SDI/UHD era, plus every supporting document: connectors, cables, fiber transmission, embedded audio, ancillary data carriage, and the compressed/SDTI-era formats that bridged SDI into early digital production. The 14-family verified Reference Guide already covers the core documents in depth (ST 259, 274, 291-1, 292-1, 296, 297, 304, 311, 318, 352, 2081-1, 2082-1/-12) — this index adds everything else in the family.

IP Media Transport — ST 2022 / ST 2059 / ST 2110 · 24 documents
ℹ
This family covers the complete ST 2022 IP transport suite, ST 2059 timing, and the core ST 2110 essence-separated media suite.
Family Overview & What's Genuinely New
▶ ST 2022 / ST 2059 / ST 2110 — Coverage Map
ST 2022-1 — Forward Error Correction for RTP
Goal: a generic FEC scheme (row/column parity) protecting any RTP-carried media against packet loss on best-effort IP networks — the loss-protection layer Branch A's compressed streams rely on.
→ ST 2022-1
→ ST 2022-1
ST 2022-2 — Unidirectional CBR MPEG-2 TS over IP
Goal: defines how a constant-bit-rate MPEG-2 Transport Stream (the format every legacy contribution encoder already produced) is packetised for one-way IP delivery — the simplest, first use case for IP contribution.
→ ST 2022-2
→ ST 2022-2
ST 2022-3 — Unidirectional VBR MPEG-2 TS over IP
Goal: extends -2 to variable-bit-rate streams (statistical multiplexing, multiple programmes sharing a circuit) — needed once IP contribution moved beyond fixed-rate single-programme feeds.
→ ST 2022-3
→ ST 2022-3
ST 2022-4 — Non-Piecewise-Constant VBR Streams
Goal: handles VBR streams whose rate changes are not simple step functions — covers real-world statmux output where bitrate varies continuously rather than in clean blocks.
→ ST 2022-4
→ ST 2022-4
ST 2022-5 — FEC for High Bit Rate Media (HBRMT)
Goal: applies the ST 2022-1 FEC concept to the much higher bit rates of uncompressed SDI-over-IP, where packet loss tolerance is far stricter than for compressed contribution feeds.
→ ST 2022-5
→ ST 2022-5
ST 2022-6 — Transport of HBRMT (SDI-over-IP)
Goal: the actual SDI-over-IP encapsulation — wraps an entire SDI signal (video+audio+ANC together, undivided) as RTP payload. Superseded in production by ST 2110's split-essence model, but still found in legacy/hybrid plants.
→ ST 2022-6
→ ST 2022-6
ST 2022-7 — Seamless Protection Switching
Goal: sends two identical copies of an RTP stream over physically diverse network paths; the receiver seamlessly selects whichever copy currently has no loss — zero-glitch failover with no switching transient. This exact mechanism reappears unchanged in ST 2110 deployments.

→ ST 2022-7
ST 2022-8 — Timing Bridge to ST 2110-10
Goal: defines how a legacy ST 2022-6 stream's timing relates to an ST 2110-10 PTP timing domain — letting a single facility run both simultaneously during a phased SDI-to-IP migration without a timing discontinuity.
→ ST 2022-8 · → ST 2110-10
→ ST 2022-8 · → ST 2110-10
ST 2059-1 — SMPTE Epoch Alignment
Goal: the absolute time reference (1 Jan 1970 TAI) and the mathematics for deriving any frame boundary from it. The network-timebase equivalent of ST 318's field-identification role.
→ ST 2059-1
→ ST 2059-1
ST 2059-2 — PTP Broadcast Profile
Goal: profiles generic IEEE 1588-2008 PTP for broadcast — replacing the blackburst/tri-level distribution cable with a network protocol carrying the same genlock function. The single most load-bearing timing standard in ST 2110.
→ ST 2059-2
→ ST 2059-2
EG 2059-10 — Introduction to the Synchronization System
Goal: a 2023 tutorial guideline (no conformance language) explaining how ST 2059 actually works in practice — written because ST 2059-1/-2's own normative prose assumes PTP familiarity that many broadcast engineers transitioning from blackburst genlock don't yet have.
→ EG 2059-10
→ EG 2059-10
RP 2059-15 — YANG Data Model for PTP Monitoring
Goal: standardises how PTP devices report monitoring data (lock status, offset, path delay) so one management tool can diagnose timing issues across a multi-vendor facility — solving the same "single pane of glass" problem that sync-generator status outputs solved for analogue genlock.
→ RP 2059-15
→ RP 2059-15
ST 2110-10 — System Timing & Definitions
Goal: the suite's foundation document — defines how every other part references a common PTP timebase (ST 2059), how RTP timestamps are calculated, and general SDP signalling rules every ST 2110 stream must follow. Revised 2023.
→ ST 2110-10
→ ST 2110-10
ST 2110-20 — Uncompressed Active Video
Goal: the video essence format itself (RFC 4175 payload) — active image only, no blanking, up to 32K×32K, Y'CbCr/RGB/XYZ/ICtCp, 4:1:1 through 4:4:4 at 8–16 bit. Extended colorimetry (PQ/HLG/Rec.2020) added 2023.
→ ST 2110-20
→ ST 2110-20
ST 2110-21 — Traffic Shaping & Delivery Timing
Goal: defines exactly how evenly a sender must space its packets — three profiles (N: rasterized/narrow, NL: narrow linear, W: wide/software) balancing network buffer requirements against sender implementation simplicity.
→ ST 2110-21
→ ST 2110-21
ST 2110-22 — Constant Bit-Rate Compressed Video
Goal: carries CBR-compressed video (JPEG XS, TICO) inside the same timing/SDP framework as uncompressed -20 — enables low-bandwidth IP video links without abandoning ST 2110's discovery and connection model.
→ ST 2110-22
→ ST 2110-22
ST 2110-30 — PCM Audio (built on AES67)
Goal: the audio essence format, built directly on AES67 — Levels A/B/C span 1–64 channels at 1 ms or 125 µs packet times. The published ST 2110-30:2017 document still normatively cites AES67-2015 — the only core part not yet revised in the 2023 wave of updates to the other parts; a revision is in progress.
→ ST 2110-30
→ ST 2110-30
ST 2110-41 — Fast Metadata Framework
Goal: based on RDD 53 — defines the low-latency RTP transport mechanism for timed metadata, carried independently of -40's ANC model. What actually rides inside this transport is defined separately, part by part: ST 2127-1/-2 for audio metadata (see next card), ST 2110-43 for captions, and ST 2110-42 (formatting) which has effectively stalled.
→ ST 2110-41
→ ST 2110-41
RP 2110-23 — Single Video Transport over Multiple Streams
Goal: a Recommended Practice (not a Standard) — splits one video essence across several parallel -20 streams, the mechanism that makes UHDTV2 (7680×4320) practical when it exceeds a single link's capacity. Published 2019, predating most of the -22/-24/-25 wave.
→ RP 2110-23
→ RP 2110-23
RP 2110-24 — SD Video over ST 2110-20
Goal: a Recommended Practice closing a gap in the original -20 design, which assumed HD/UHD rasters — adds the parameters needed for legacy SD format compatibility inside an otherwise IP-native facility.
→ RP 2110-24 · → ST 2110-20
→ RP 2110-24 · → ST 2110-20
RP 2110-25 — Measurement Practices
Goal: a Recommended Practice standardising how to test ST 2110 stream conformance — timing accuracy, traffic shaping compliance, common nomenclature and formulas — so test-and-measurement vendors and broadcasters validate equipment against the same criteria. Split out from ST 2110-21 after its one-year review.
→ RP 2110-25
→ RP 2110-25
Microservices & Security
OV 2110-0 — Roadmap for the 2110 Document Suite
Goal: SMPTE's own official roadmap diagram tying every ST 2110 part together — the same navigational role EG 2111-1/-2/-3 play for the SDI family.
→ OV 2110-0
→ OV 2110-0
ST 2126 — Microservice Status Reporting and Logging
Goal: a standardised status-reporting and logging framework for media microservices, originated by the Open Services Alliance with IETF/EBU input and brought to SMPTE in 2020 — aims to standardise status/logging interoperability across vendors, who previously each used their own incompatible job-status formats. Built around a job/log-entry/transaction-tracker model. ST 2125 (IMF Registration API) is its sibling document from the same OSA collaboration, not covered in this catalog excerpt.
→ ST 2126
→ ST 2126
RP 2129 — Inter-Entity Trust Boundary
Goal: as facilities migrate their final broadcast composite handoff from unidirectional SDI/ASI to bidirectional IP (often ST 2022/2110), new security and address-space risks emerge. RP 2129 (2023) defines a "Trust Boundary" — a media-specific firewall function at an entity's network edge with explicit trusted/untrusted interfaces, dropping all traffic by default except permitted flows. Net Insight has shipped commercial products built directly on this standard since 2023 (Trust Boundary Appliance) and announced "Facility Protect" at NAB 2025, citing RP 2129 by name in its own marketing materials — independent trade-press confirmation of real deployment, not merely a standards description.

Video Codecs — VC-1 through VC-6 · 26 documents
ℹ
Six independent codec generations, each following the same documentation pattern: a bitstream/elementary-stream specification, a conformance or decoder-testing document, and transport/storage mapping documents.
VC-2 / VC-5 Core Specifications
ST 2042-1
VC-2 Core Coding (Dirac Pro) — standardises BBC R&D's open, royalty-free wavelet codec, an alternative to licensed codecs for public-service and royalty-sensitive broadcasters.
→ ST 2042-1
→ ST 2042-1
ST 2042-2 / RP 2042-3
VC-2 Level Definitions (-2) define conformance levels so decoders declare exactly which bitstream variants they support; the Conformance Specification (RP -3) provides the test specification.
→ ST 2042-2 · → RP 2042-3
→ ST 2042-2 · → RP 2042-3
ST 2073-1
VC-5 Compression, Part 1: Elementary Bitstream — standardises GoPro's CineForm codec (announced June 2015), an open, variable-bit-rate, wavelet-based intra-frame codec for acquisition/post.
→ ST 2073-1
→ ST 2073-1
ST 2073-3
VC-5 Part 3: Image Formats — defines the image-format tags VC-5 elementary bitstreams declare: sample structure, colour sampling, and similar image-format metadata.
→ ST 2073-3
→ ST 2073-3
ST 2073-7
VC-5 Part 7: Metadata — defines metadata carriage within a VC-5 elementary bitstream itself, distinct from the file-level/container metadata carried by MXF once VC-5 is wrapped via ST 2073-10.
→ ST 2073-7
→ ST 2073-7
RP 2073-2
VC-5 Conformance Specification — the reference encoder/decoder and bitstream test vectors verifying any VC-5 implementation against the standard.

VC-1 — ex-Microsoft WMV9 (ST 421, 2006)
ST 421
VC-1 compressed video bitstream format and decoding process — Microsoft's WMV9, standardised by SMPTE after a three-year approval process. Three profiles: Simple, Main, Advanced.

VC-4 — Scalable Layer Extension (ST 2058, 2011)
ST 2058-1
Goal: the SMPTE Layered Video Extension (LVE) — not a standalone codec. VC-4 defines enhancement layers that improve a base-layer picture decoded by another standard codec (VC-1, MPEG-2/H.262, MPEG-4 Part 2, or AVC/H.264), with the base and enhancement streams synchronised at the system layer. Outputs 8-16 bit samples in 4:2:0/4:2:2/4:4:4.
→ ST 2058-1
→ ST 2058-1
RP 2058-2 / RP 2058-3

→ RP 2058-2 · → RP 2058-3
→ RP 2058-2 · → RP 2058-3
RP 2058-4
VC-4 bitstream storage in the ISO Base Media File Format — explicitly extends whichever base-layer file format VC-4 is layered on top of (e.g. the AVC/HEVC NAL-unit storage format, ISO/IEC 14496-15), referencing VC-1's own RP 2025 storage document directly.

VC-6 — V-Nova Multiplanar Format (ST 2117, 2023)
ST 2117-1
VC-6 Part 1: Elementary Bitstream — first standardised 2020, developed with V-Nova; uses an AI-influenced hierarchical S-Tree structure rather than DCT or wavelet transforms, giving intrinsic full-resolution proxy access and region-of-interest decoding. Current edition 2023. Its MXF mapping (ST 2117-10) is covered in F02 MXF; an IMF application profile for VC-6 (ST 2067-71) exists but is outside this catalog excerpt's scope.

Identifiers, Metadata Dictionaries & Registers · 29 documents
ℹ
This family covers the dictionary/register infrastructure underlying SMPTE metadata generally, plus the identifier systems built on top of it: content/advertising/distribution-channel identifiers and the encoding/naming conventions supporting them. ST 395, ST 400, ST 2088, ST 2123, and ST 330 are detailed in full in F02 MXF, cross-referenced rather than duplicated below.
Dictionary/Register Infrastructure
ST 335
Metadata Element Dictionary Structure — the formal structure rules for how a metadata dictionary itself must be organised, the "dictionary of dictionaries" that ST 2123 and other metadata registries are built to comply with.

RDD — Registered Disclosure Documents: Vendor & Camera Formats · 23 documents
ℹ
An RDD is a vendor-submitted specification that SMPTE registers and publishes but does not standardise through the normal ST/RP process — useful for documenting a proprietary or de facto format without claiming consensus. This page covers all standalone RDDs not already absorbed into the MXF, D-Cinema, or Codecs families above (where ProRes/ARRIRAW/MGA-related RDDs are directly tied to those formats).

AES3 Non-PCM Audio & Compressed Audio Data Types · 19 documents
ℹ
AES3 is a two-channel linear PCM interface by design. ST 337 modifies its frame/subframe usage to carry non-PCM data instead — and every other document in this family registers exactly one "data type" that can ride inside that carrier. This is the same extensibility pattern MXF uses for essence mappings, just one layer down at the AES3 wire level.

Colour Bar & Monitor Alignment Lineage, Safe Areas, Display Reference
▶ Test Signals, Safe Areas & Display Reference White — NTSC through UHD
Test Signals & Monitor Alignment
EG 1
Alignment Color Bar Test Signal for Television Picture Monitors — first published 1990 as a revision of the earlier ECR 1-1978; lists first in the catalog by document number, not by publication date (ST 12-1's 1975 adoption predates it). Establishes the basic colour-bar test pattern concept that RP 219-1/-2 later extend to HD/UHD.

Safe Areas
RP 218 / ST 2046-1

RP 2046-2 / EG 2046-3
Safe Areas for Protection of Alternate Aspect Ratios (2046-2) — extends ST 2046-1's safe-area concept to handle content mastered for one aspect ratio but distributed in another; Safe Areas for Television, the companion engineering guideline (2046-3).

→ RP 2046-2 · → EG 2046-3
HDTV Display Reference
ST 2080-1 / RP 2080-2
Reference white luminance level and chromaticity for HDTV (2080-1) — the display reference point everything else in HDTV colour calibration is measured against; the corresponding measurement and calibration procedure (2080-2).
→ ST 2080-1 · → RP 2080-2
→ ST 2080-1 · → RP 2080-2

→ ST 2080-3
→ ST 2080-3
Camera-Specific Lighting Quality
RP 2093
Goal: the Television Lighting Consistency Index (TLCI) — developed because the generic lighting Color Rendering Index (CRI) was never designed for television camera/white-balance behaviour. TLCI mimics a complete television camera and display rather than the human eye, scored 0-100, and is mathematically identical to EBU Tech 3355. Optimised for ITU-R BT.709 but also useful for BT.2020/BT.1886 assessment.

Digital Control Interface & Remote Equipment Control · 12 documents
ℹ
The Digital Control Interface (DCI) is the RS-422-era predecessor to today's NMOS/Catena device-control standards — a general-purpose channel and device architecture for interconnecting programmable and non-programmable production equipment, designed for both fixed-plant and field use, supporting rapid reconfiguration into different operational functions. ESbus/ESlan is a separate, parallel broadcast-automation bus sharing only a virtual-machine-number registry with the rest of this family.

HDR & Colour Volume Metadata — Remaining Catalog Entries · 9 documents
ℹ
This family covers the ST 2084 PQ transfer function, the six-part ST 2094 dynamic HDR metadata suite, the suite roadmap, and a specialised colour-difference standard. Note: ST 2087 ("Depth Map Representation") was initially grouped into this family by keyword matching on "metadata," but is in fact a stereoscopic-3D document directly related to ST 2066's Disparity Map Representation — it is covered in F16 Stereoscopic 3D instead, not here.
HDR Core Specifications
ST 2084
Perceptual Quantizer (PQ) — an EOTF mapping code values to absolute luminance up to 10,000 cd/m², solving the problem that gamma curves derived for ~100 nit CRT displays couldn't represent HDR's wider range. The foundation transfer function for HDR10 and Dolby Vision.

Time Code & Synchronisation — Legacy Catalog Entries · 9 documents
ℹ
ST 12-1/-2/-3 (the core timecode standard family) are detailed in full in F07 Ancillary Data above. This page covers the binary-group ("user bits") extension ecosystem — the 32 spare bits every SMPTE timecode frame carries, and the competing/companion ways different standards have used them since.
ST 12-1's 32 User Bits — Two Different Ways to Use Them
▶ ST 262's Directory System vs. ST 309's Date/Time-Zone Encoding
Binary Group Directory & Date/Time Encoding
ST 262
Goal: Binary Groups of Time and Control Codes — defines a self-identifying page-line directory index, located in binary groups 7 and 8, that classifies what data the remaining user-bit groups carry. Applies to both linear and vertical-interval timecode.
→ ST 262
→ ST 262
ST 309
Goal: Transmission of Date and Time Zone Information in Binary Groups of Time and Control Code — an alternative way of using the same 32 user bits, carrying date, UTC time-zone offset, and DST flag directly rather than through ST 262's directory system. The two approaches are alternatives, not companions: a given timecode stream uses one or the other.
→ ST 309

ST 2087 ("Depth Map Representation") was redirected here from F13, where it had been misclassified by keyword matching — it is in fact directly related to ST 2066 below. Several stereoscopic transport/packaging documents (ST 292-2, ST 425-2/-4/-6 in F01; ST 429-10 in F05) are tightly integrated into their respective transport/packaging families and are cross-referenced here rather than duplicated.
ST 2068 — The Signaling Document Tying the Whole Family Together
▶ Stereoscopic 3D: Signaling, Depth/Disparity, Contribution & Production Guidance
Frame-Compatible Signaling & Its SDI/D-Cinema Dependencies
ST 2068
Goal: defines a 3D Frame Compatible (3DFC) ancillary data packet, carried in VANC, that enumerates the frame-packing method (side-by-side, top-bottom, line-by-line, checkerboard, etc.) used for a sub-sampled stereoscopic image pair — compatible with the ITU-T H.264/MPEG-4 AVC Frame Packing Arrangement SEI message. Depends directly on ST 291-1 (VANC carriage), ST 424/292-2/425-2/-4/-6 (the dual/quad-link stereoscopic SDI transports, all in F01).

Other Engineering Standards — Long Tail · 105 documents
ℹ
The final 105 catalog entries don't share a common architecture, transport, or signaling system the way every other family in this index does — each genuinely stands alone, typically addressing a narrow mechanical, recording-format, or measurement problem specific to its era. Several items originally swept into this bucket by keyword matching were redirected to their proper homes during this audit: ST 2052-1/RP 2052-10/OV 2052-0 (captions, F07), ST 2080-3/RP 2046-2/EG 2046-3 (colour science/safe areas, F11), ST 2034-1 (AXF, F10), and OV 2112-0/EG 2112-2/ST 2021-1/OV 2021-0/RP 2021-1 (OBID/BXF roadmaps, F06/F10). ST 2071-1/-3 (Media Device Control) are detailed below.
Media Device Control
ST 2071-1
Media Device Control Framework — defines media (not the device that holds it) as the first-class object to be controlled, a deliberate inversion of traditional device-control thinking. Devices and services are modelled as sets of independently identified "capabilities" that can be combined and changed dynamically at runtime, intended to address the same heterogeneous-device control problem that Catena/ST 2138 addresses a decade later.
→ ST 2071-1
→ ST 2071-1

Film Mechanical & Photographic Standards · 122 documents
ℹ
These are physical-geometry standards — perforation patterns, sprocket dimensions, splice specifications, camera apertures, and similar mechanical/photographic tolerances for 35mm, 16mm, 8mm, and other film gauges. Unlike SDI, MXF, or IP-media families, there is no signal, transport, or container architecture connecting them; each is an independent dimensional or photographic specification for a specific film format and era.

ST 2138 — Catena Control Plane · 7 documents
ℹ
Catena is a unified, open, secure, vendor-agnostic control plane for media systems, originated in SMPTE's Rapid Industry Solutions Open Services Alliance (RIS-OSA) to solve a real, named problem: hundreds of incompatible proprietary control protocols across on-premises, cloud, and hybrid media environments. The initial document suite entered formal SMPTE standardisation via Technology Committee 34CS (Media Systems Control and Services) in June 2025, and as of this index is still progressing through Public Committee Draft review — every ST 2138 part below is a draft, not yet a published Standard.
Catena's Model, Connection Types & Cross-Cutting Parts
▶ ST 2138 — Model, Connections, Protocol Objects & Security
Core Model & Roadmap
OV 2138-0
Roadmap for the 2138 Document Suite — the official overview tying every Catena part together. Listed by SMPTE as "Document pending" / availability pending at time of writing.
→ ST 2138 Standards Page
→ ST 2138 Standards Page
ST 2138-10
Goal: Catena Model — specifies the schema for plug-and-play communication and control of media services and devices across cloud, on-premises, and hybrid cloud/on-premises platforms. Also defines a number of Access Scopes reflecting how media production equipment is used across different use cases. Currently a Public Committee Draft.
→ GitHub PCD
→ GitHub PCD
Connection Types
ST 2138-11
Goal: gRPC Connection Type — defines the use of a gRPC connection manager with Catena: Protobuf serialisation over HTTP/2, for high-performance, schema-strict control. Currently a Public Committee Draft.
→ GitHub PCD
→ GitHub PCD
ST 2138-12
Goal: REST Connection Type — specifies the use of a REST connection manager with Catena: Protobuf or JSON over HTTP/1.1, for simpler HTTP-based integration. Currently a Public Committee Draft. Note: the Catena Model also documents a WSS (WebSocket Secure) connection option using the same Protobuf-or-JSON/HTTP/1.1 pairing as REST, but WSS does not yet have its own dedicated ST 2138 part.
→ GitHub PCD
→ GitHub PCD
Protocol Objects & Security
ST 2138-19
Goal: Protocol Objects — defines the objects that are exchanged between participants using the ST 2138 protocol, independent of which connection type (gRPC/REST/WSS) carries them. Currently a Public Committee Draft.
→ GitHub PCD
→ GitHub PCD
ST 2138-50
Goal: Authenticity, Integrity, Access Control, Confidentiality and Availability — specifies how to securely use the Catena control protocol, addressing security-by-design for the control plane (a gap NMOS BCP-003 leaves for discovery but no prior SMPTE document addressed for device control specifically). Covers client/device mutual verification, OAuth2 access-token flows and revocation, Policy Enforcement Point responsibilities (optionally split between devices and gateways), transit confidentiality, and using JWS (rather than opaque tokens) so devices avoid round-trips to an Authorization server for introspection. Currently a Public Committee Draft.

Reference Implementation
ST 2138-a
Elements Repository for SMPTE ST 2138 Catena API Implementation — an API implementation applicable to all parts of the ST 2138 document suite. A separate, vendor-built reference implementation (the Ross Video Catena SDK) is also publicly available, unaffiliated with this repository.
