Full title and description

IEEE Std 1857.4-2018 — IEEE Standard for Second-Generation IEEE 1857 Video Coding. This standard specifies a set of efficient video coding tools (intra/inter prediction, transform, quantization and entropy coding) and the corresponding decoding procedures for advanced video compression and delivery applications.

Abstract

IEEE 1857.4-2018 defines a second‑generation video coding toolset intended to provide improved coding efficiency over the earlier IEEE 1857 family. Key techniques include directional intra prediction, variable block‑size inter prediction, context adaptive binary arithmetic coding (CABAC), transform and quantization methods, and their decoding counterparts. Target applications include UHDTV, IP‑based video surveillance, Internet video, video conferencing, IPTV and other video/audio-enabled services.

Scope

This standard specifies a complete set of coding and decoding tools for second‑generation IEEE 1857 video compression, including intra prediction, inter prediction with variable block sizes, transform and quantization, entropy coding (including CABAC), and the associated bitstream/decoder procedures needed to implement compliant encoders and decoders. It is intended for use across broadcasting, streaming, surveillance, conferencing, storage and related video delivery systems.

Key topics and requirements

• Directional intra prediction modes and mechanisms for improved spatial prediction.
• Variable block‑size inter prediction with motion compensation to support diverse content and resolutions.
• Context Adaptive Binary Arithmetic Coding (CABAC) or equivalent entropy coding schemes for efficient bitstream compression.
• Transform and quantization definitions and constraints needed for encoder/decoder interoperability.
• Bitstream syntax and decoding procedures required to produce compliant decoders and ensure interworking.
• Support considerations for target applications including UHDTV, IP surveillance, IPTV, and internet video delivery.

These topics form the normative requirements implementers must follow to achieve compliance with IEEE 1857.4-2018.

Typical use and users

Typical users include codec designers and implementers, SoC and device manufacturers, streaming platform engineers, broadcast system architects, video surveillance system vendors, multimedia software developers, and standards/deployment testers. The standard is used to guide encoder/decoder implementations, interoperability testing, product development and integration into media delivery chains.

Related standards

IEEE 1857.4-2018 is part of the IEEE 1857 family (which includes IEEE 1857, 1857.2, 1857.3, 1857.5, 1857.6, 1857.7, 1857.8, 1857.9, 1857.10, etc.). Newer and related projects (for example later 1857 system, third‑generation video efforts and other 1857 parts) reference or build on 1857.4. Implementers commonly consider IEEE 1857.3 (system/packaging), 1857.2 (audio), and other 1857 parts when integrating codecs into complete solutions.
