Here is the opening snippet:

In 2004, the Institute of Electrical and Electronics Engineers (IEEE) started an Ethernet study group for AV streaming. This became the Audio Video Bridging (AVB) Task Group that now serves four industries – professional AV, consumer electronics, automotive, and most recently the industrial control industry. At the end of 2012 this task group was renamed Time Sensitive Networking (TSN) to reflect a more accurate focus for the expanded scope of their work.

To understand why TSN is important to pro AV, we have to take a step back and look at key companies – like Intel, Cisco, General Electric (GE), and National Instruments (NI) – whose job it is to support the development of products belonging to IoT (Internet of Things), and understand that TSN is viewed as enabling the technology that will be part of the ‘next big thing’ or the technological evolution for IoT.
