SMPTE 2059
SMPTE 2059 is a standard from the Society of Motion Picture and Television Engineers (SMPTE) that describes how to synchronize video equipment over an IP network.[1] The standard is based on IEEE 1588-2008. SMPTE 2059 is published in two parts on 9 April 2015:
- SMPTE 2059-1 – Defines signal generation based on time information delivered by the IEEE 1588 protocol.[2]
- SMPTE 2059-2 – Defines an operating profile for the IEEE protocol optimized to the needs of media synchronization.[3]
SMPTE 2059 is an integral part of emerging professional IP video broadcast technology and standards.[4][5]
In May 2016, the Audio Engineering Society published a report describing synchronization interoperability between AES67 and SMPTE 2059-2.[6]
