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.{{cite magazine |title=SMPTE ST 2110-21: Taming the Torrents |url=https://www.tvtechnology.com/opinions/smpte-st-211021-taming-the-torrents |magazine=TV Technology |author=Wes Simpson |date=February 9, 2018}} |

===ST 2110-22: Constant bit-rate compressed video transport=== |

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 {{citation |url=http://www.ipshowcase.org/wp-content/uploads/2019/05/1230-Jean-Baptiste-Lorent-IPShowcase-NAB-2019-JPEG-XS-and-ST2110_intoPIX_JeanBaptisteLorent.pdf |title=JPEG XS and ST 2110 |date=12 April 2019 |publisher=AIMS Alliance}} 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,[http://ds.jpeg.org/whitepapers/jpeg-xs-whitepaper.pdf JPEG XS White Paper], which is less than 1 millisecond. SMPTE 2110-22 is used as an alternative to uncompressed video (SMPTE 2110-20) in a live production environment. SMPTE 2110-22 is indeed very suitable for using less bandwidth in local live IP production, remote production, contribution or cloud-based production.{{Cite web|url=https://www.smpte.org/webcast/JPEGXSLIVEIP|title=Understanding JPEG XS for Live IP and Remote Production|access-date=2021-08-06|archive-date=2021-08-06|archive-url=https://web.archive.org/web/20210806074747/https://www.smpte.org/webcast/JPEGXSLIVEIP|url-status=dead}} |
