Leveraging layered division multiplexing (LDM) and real-time SHVC technology in an ATSC 3.0 environment, the joint solution offers increased bandwidth efficiency for broadcast content delivery over the air (OTA) and via broadband.

The demo featured a full chain of ATSC 3.0-compatible equipment including the Triveni Digital GuideBuilder XM metadata generator and MMTP/ROUTE encoder, a Titan encoder from Ateme, a broadcast gateway, a transmitter and the Samsung ATSC 3.0 television prototype for reception. Additionally, Triveni Digital’s StreamScope XM MT ATSC 3.0 analyser will be utilised to showcase the two layers of MMTP/ROUTE data.

“We are very proud to extend our partnership with Triveni Digital in this successful demonstration that will rise the movement toward a flexible ATSC 3.0 deployment,” said Mickaël Raulet, advanced research manager at Ateme. “Our Titan Live encoder provides an evolutive solution for ATSC 1.0 and ATSC 3.0 deployments.”

“In the past, broadcasters were required to use a significant amount of bandwidth to deliver content over the air and over broadband, which was very expensive,” added Ralph Bachofen, vice president of sales and marketing at Triveni Digital. “With GuideBuilder XM supporting SHVC for both OTA and broadband transmissions, this is no longer an issue. We’re excited to team up with Ateme on this innovative end-to-end solution, which is ready for real-world deployment.”
