The protocol, device discovery, connection management, and device-control procedures used to facilitate interoperability between audio- and video-based end stations that use IEEE 1722-based streams on IEEE 802-based networks are specified.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
P1722
Standard for a Transport Protocol for Time-Sensitive Applications in Bridged Local Area Networks
This standard specifies extensions to IEEE Std 1722™ to add support for ITU-T (Telecommunication Standardization Sector of ITU) Recommendation H.265 v7 (11/2019) -- High efficiency video coding -- and AOMedia Video 1 video compression format (AV1), support for various image sensors using Generic Image Sensors Format (GISF), and Audio/Video Transport Protocol (AVTP) Control Format (ACF) for additional data types including Inter-Integrated Circuit (I2C), Serial Peripheral Interface (SPI), Controller Area Network extended data-field length (CAN_XL) and others. This standard helps to improve the Clock Reference Format (CRF) format, the CAN (Controller Area Network) and LIN (Local Interconnect Network) formats, and support for tracking Grandmaster Clock (as defined in IEEE Std 802.1AS-2020™) changes supporting longer presentation time intervals and Grandmaster Identity. This standard adds AVTP version 1 optional headers. Use case specific annexes are added to support ACF types where needed. This project also fixes various bugs found in the previous revision of the standard.
P1722b
Standard for a Transport Protocol for Time-Sensitive Applications in Bridged Local Area Networks - Amendment: New and Extended Streaming Formats
This project specifies extensions to IEEE Std 1722 to add support for ITU-T (Telecommunication Standardization Sector of ITU) Recommendation H.265 v7 (11/2019) - High efficiency video coding and AOMedia Video 1 video compression format (AV1), and a new audio format that supports temporal redundancy. This project improves the Clock Reference Stream (CRS) format, enlarges the Audio/Video Transport Protocol (AVTP) sequence number, improves the CAN (Controller Area Network) and LIN (Local Interconnect Network) formats, improves support for tracking grandmaster changes, supports longer presentation time intervals, clarifies clock stability indicators, and provides guidance on how to handle out-of-order arrival of AVTP Protocol Data Unit (PDUs).
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
1722-2016/Cor 1-2016
IEEE Approved Draft Standard for a Transport Protocol for Time Sensitive Applications in a Bridged Local Area Network- Corrigendum 1
Correct additional fields text in AES3 Stream Format section of Annex I. (NOTE: This corrigendum was not published as a separate document, but was incorporated in IEEE Std 1722-2016)
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
1722-2011
IEEE Standard for Layer 2 Transport Protocol for Time Sensitive Applications in a Bridged Local Area Network
The protocol, data encapsulations, and presentation time procedures used to ensure interoperability between audio- and video-based end stations that use standard networking services provided by all IEEE 802 networks meeting quality-of-service requirements for time-sensitive applications by leveraging concepts of IEC 61883 are specified in this standard.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
