Broadcast company ARK Multicasting has tested edge caching of video content over next-gen TV standard ATSC 3.0.
ATSC 3.0 is the latest standard from the Advanced Television Systems Committee which determines how TV signals are broadcast and interpreted.
The benefits of ATSC 3.0 for consumers include improved reception, 4K UHD resolution, HDR, and Dolby Atmos support—all over-the-air.
Madeleine Noland, President of the ATSC, said:
“It’s very exciting to see new and innovative implementations of ATSC 3.0 come to life. Edge caching content in the home can serve a wide variety of purposes from relieving congestion on two-way IP networks to providing needed connectivity to rural or under-served populations.
For example, classroom content could be pre-loaded in students’ homes so that bandwidth isn’t an issue during remote classes, and I can envision many other applications of this feature of ATSC 3.0”
ARK’s demo showed caching of 4K video, PDFs, Word documents, Keynote, and PowerPoint files on a consumer edge device. The files were transmitted using a Low Power TV (LPTV) broadcast.
The consumer edge caching took place simultaneously with live linear TV seen on a Sony ATSC 3.0 TV separate from the caching device.
Joshua Weiss, CEO of ARK Multicasting, commented:
“This goes a long way in proving how ARK is the solution to the current congested networks across America, and the underserved who lack broadband.
We are now able to move the most popular videos, software, and gaming updates, and other data files all the way to the end user’s home making the home part of the larger cloud.”
ARK’s pilot was conducted in partnership with Hitachi-Comark and the Comark Digital Services integration team.
“By shifting the traditional ‘edge’ all the way to the consumer home, we relieve last-mile congestion and enhance the user experience,” concluded Weiss.
