Broadcaster's Guide to SMPTE 2022 by Artel
Introduction
Proprietary systems for transporting video have existed since the dawn of the television age. It’s difficult to walk into a broadcast facility more than ten years old that doesn’t have some piece of proprietary video transport equipment tucked away in a corner. Many of these units are single vendor solutions, which become obsolete as soon as the supplier stops supporting them or moves on to a new generation.
SMPTE 2022 standard
SMPTE 2022 is a global standard that has been deployed by broadcasters around the world. It supports video formats from all of the different television systems, including 525 and 625 line SD systems, 50 Hz and 60 Hz progressive and interlaced HD signals, and compressed signals employing the MPEG-2 TS (Transport Stream) container format.
Typical application
*Long haul contribution and backhaul Video contribution is the process of transmitting high-quality video from a remote source (such as a sports arena) to a broadcast facility for production and distribution. Backhaul is the process of taking a fully produced linear video channel (such as from a local broadcast affiliate) and sending it to a national or regional television delivery provider, such as a satellite TV, CATV, or OTT operator. Typically, backhaul and contribution links are relatively few in number, can sometimes cover long distances, and tend to focus on lowdelay, high-quality video signal formats.
