Is ATSC 3.0 really a Trojan Horse for next-generation AV and Collaboration?

Is ATSC 3.0 really a Trojan Horse for next-generation AV and Collaboration?

You may have seen the latest headline coming out of CES in Las Vegas last week about the Advanced Television Systems Committee (ATSC) release of ATSC 3.0, or more accurately stated the standards suite of protocols. How does this release impact the Audiovisual and Integrated Experience Association (AVIXA) members and the design of AV systems in general?

Gigabit Multimedia Serial Link (GMSL)

Gigabit Multimedia Serial Link (GMSL) serializer and deserializer (SerDes)

Right now this is a sort of standard built around Maxim's chips.
It seems to be used almost exclusively in the self driving car / automotive industry.

power and data is carried over a single Coax cable to a GMSL camera.





Maxim Integrated’s MAX9272A and MAX9275 gigabit multimedia serial link (GMSL) serializers and deserializers (SerDes) used in the Surround View Kit are designed primarily for automotive video applications such as ADAS & Infotainment. Maxim’s GMSL SerDes technology provides a compression-free alternative to Ethernet, delivering 10x faster data rates, 50% lower cabling costs, and better EMC. The ADAS Starter Kit comes with coax cables having a length of 20cm, but they can be exchanged to longer ones as Maxim's GMSL chipsets drive 15 meters of coax or shielded twisted-pair (STP) cabling, thereby providing the margin required for robust and versatile designs
