In the transition to transporting video over IP (Internet Protocol) infrastructures, it is essential that broadcasters maintain a common, ubiquitous set of protocols and practices for transmission of video and audio over IP. The same level of interoperability must remain in order to ensure the same plug-and-play compatibility among various manufacturers' products.
Substantial progress has been made by standards-making bodies like SMPTE and the EBU in insuring a high level of compatibility between IP devices. Introduced in 2007, SMPTE 2022 is a universal, global standard to move video signals over IP networks. Covering both compressed and uncompressed standard and high definition video, the 2022 standard allows equipment from multiple manufacturers to work together seamlessly.
The ongoing, widespread adoption of SMPTE 2022, a series of standards based on work from the SMPTE and Video Services Forum (VSF), has enabled broadcasters to transport error free video throughout the studio and across managed IP networks. Today, the SMPTE standard has been expanded to cover uncompressed video, audio, and data at speeds up to 3 Gbps and beyond.
Today, having a cost-effective, single converged infrastructure for many different types of signals is encouraging the migration towards IP-based technologies on many level from video contribution, the process of transmitting HD video from a remote source (such as a sports arena) to a broadcast facility for production and distribution, to distributing a fully produced linear video channel (such as from a local broadcast affiliate) via backhaul and sending it to a national or regional television delivery provider, such as a satellite TV, CATV or OTT operator.
Contribution and backhaul links can involve long distances and tend to focus on low-delay, high-quality video signal formats. Long distance IP networks have become more cost-effective due to bandwidth-saving compression using JPEG 2000 and other compression solutions. More broadcasters are migrating their contribution and backhaul video circuits towards managed IP networks. This trend is particularly apparent in terrestrial point-to-point services that replace dedicated satellite circuits.
