SMPTE 2110 is a suite of standards from the Society of Motion Picture and Television Engineers (SMPTE) that describes how to send digital media over an IP network.[1]
SMPTE 2110 is intended to be used within broadcast production and distribution facilities where quality and flexibility are more important than bandwidth efficiency.[2]
SMPTE 2110 was based on the TR-03[3] and TR-04[4] work published by the Video Services Forum on 12 November 2015. The first four parts of SMPTE 2110, -10, -20, -21 and -30, were published by SMPTE on 27 November 2017. Other parts, including recommended practices, were added later, and several parts were updated in 2022.
SMPTE 2110 is specified in several parts:[5]
There are several important features of ST 2110-10:[11]
SMPTE 2110-20 defines the key requirements for transporting uncompressed video essence and is built on the IETF RFC 4175, RTP Payload Format for Uncompressed Video. [12]
SMPTE 2110-21 defines three classes of devices based on their transmission timing behavior: NL (for Narrow Linear), N (for Narrow), and W (for Wide). NL senders transmit at a constant bit rate. N senders may suspend transmission during the vertical blanking interval. W senders are intended to support software implementations of 2110 and adhere to less rigorous transmission timing requirements. A type W receiver should be able to receive from any type of sender.[13]
SMPTE 2110-22 defines the key requirements for transporting compressed video essence. The compression standard needs to provide a constant bitrate, a defined RTP payload and low latency to satisfy the needs of Live production. The majority of the SMPTE 2110-22 implementations uses the JPEG XS lightweight low latency compression standard [14] created by the Joint Photographic Experts Group to answer the requirements of the SMPTE 2110 standard. The JPEG XS codec has only a few video lines of latency in software and hardware implementations,[15] which is less than 1 millisecond. SMPTE 2110-22 is used as an alternative to uncompressed video (SMPTE 2110-20) in live production environment. SMPTE 2110-22 is indeed very suitable to use less bandwidth in local live IP production, remote production, contribution or cloud-based production.[16]
The 2110 suite also includes SMPTE Recommended Practices:
