With standardization for the transport layer in place and the number of systems being deployed growing, media over IP is now a viable option for our industry. 2019 is focused on usability, and once this becomes readily accessible we can truly move from an early adopter phase to mass market adoption.
So where do we stand today?
Interoperability has been proven. What’s missing is simplified and more secure integration. Part 1 of this blog series explained how JT-NM’s TR 1001-1 technical recommendation, which encompasses AMWA’s IS-04 and IS-05, is tackling the issue of simplifying connectivity. Part 2 will delve into other hot topics for media over IP trends in 2019, with a focus on compressed video delivery over IP, and where we stand on security.
Compressed Video Over IP is the Goal With SMTPTE ST 2110-22
If you’re not familiar with SMPTE ST 2110-22, it is because the standard is not yet a published part of the SMPTE ST 2110 suite of standards. Using video compression in conjunction with the rest of the SMPTE ST 2110 universe, the new standard will enable more effective use of network connectivity for real-time workflows where latency is an issue. It’s all about compressed video over IP, which will come in handy for carrying HD video over 1GigE connections and UHD over 10GigE connections.
The actual codec to be used is not specified. While not published yet, it will enable compressed video to be used in conjunction with the same timing, audio and data standards that make up the rest of the SMPTE ST 2110 suite of standards. The likely candidates for compression technology are JPEG-XS and VC-2.
What about Security Over IP?
In an all-IP world, network security is on everyone’s mind, and even more so if you want to add real-time uncompressed video, audio, and data to your network infrastructure. Whether protecting assets or access to real-time workflows, production and broadcast networks of the future will carry all forms of content. Protecting the network and assessing the vulnerability of devices on it will be an important topic with basic I/O and connection management tools in place. Best practices for media over IP are evolving, and we can expect to hear more on this topic throughout the year.
