The JPEG Committee has finalized the JPEG XE standard (ISO/IEC 26112-1) as the first international standard for lossless coding of visual events from event-based vision sensors. The committee also advanced several other standards, including JPEG Trust, JPEG DNA, JPEG Pleno, JPEG XS, and JPEG AI, during its 112th meeting in Leiria, Portugal.
The finalization of the JPEG XE standard provides a critical technical bridge between sensor manufacturers and software developers in the emerging event-based vision market. By establishing a unified framework for lossless coding, the standard reduces fragmentation for automotive and industrial streaming applications that require high-precision visual data. This development aligns with broader industry shifts toward learning-based media coding, as seen in the committee's concurrent progress on JPEG AI and JPEG Trust. The integration with MIPI Alliance protocols suggests a rapid path to hardware adoption for low-latency vision systems. Watch for the publication of Part 5 metadata structures to see how atomic time synchronization impacts real-time industrial automation.
The JPEG Committee's finalization of JPEG XE builds on a multi-year standardization effort spanning three organizations. At the 111th meeting in April 2026, JPEG XE Part 1 reached the DIS stage while the committee converged on an ISOBMFF-based file format design for Part 5, supporting efficient storage, streaming, and precise event timestamping. The joint AHG between ITU-T SG21 and ISO/IEC JTC1/SC29/WG1 was reestablished at that meeting to continue development, and the standard will also be published as ITU-T Recommendation T.841.1, giving it dual recognition across both the telecom and ISO/IEC standards ecosystems.
The business and interoperability case for JPEG XE is anchored in its liaison with the MIPI Alliance. ISO/IEC 26112-2 includes the Embedded Lossless Constrained Profile, specifically designed to enable interoperability with the MIPI CSI-2 v4.2 Event Stream Protocol specification, representing the successful outcome of a close liaison between the MIPI Alliance and the JPEG Committee to promote industry-wide interoperability for event-based imaging systems. This profile gives sensor and SoC vendors a direct path to integrate JPEG XE into existing camera serial interface pipelines without requiring a new transport layer.
From a technical trajectory perspective, the JPEG Committee began assessing responses to its Call for Proposals on Lossless Coding of Visual Events at its 107th meeting in Brussels in May 2025, meaning the standard progressed from proposal evaluation to final International Standard text in roughly 14 months. The committee's next meeting, the 113th, is scheduled for Hangzhou, China in October 2026, where work on Part 4 compliance testing and Part 5 metadata structures is expected to continue. The broader JPEG portfolio also advanced at the 112th meeting, with JPEG Trust and JPEG DNA both reaching new milestones, signaling sustained institutional investment across the committee's full family of imaging standards.

JPEG XE (ISO/IEC 26112-1) is the first international standard for the lossless coding of visual events from event-based sensors, also published as ITU-T Recommendation T.841.1.
The standard includes an Embedded Lossless Constrained Profile designed to work with the MIPI CSI-2 v4.2 Event Stream Protocol, allowing vendors to integrate JPEG XE into existing camera serial interface pipelines.
It provides a critical technical bridge for the event-based vision market, reducing fragmentation for automotive and industrial streaming applications that require high-precision visual data.
Future work includes defining formal compliance testing in Part 4 and developing metadata structures in Part 5 to synchronize event timestamps with atomic time references.
