Signaling & Delivery server for ATSC 3.0 network

MediaCast is ENENSYS’s virtualized software designed to support the delivery of live content from HEVC encoders or of non-real-time content over ATSC 3.0 networks using ROUTE or MMTP protocols


  • Linear contents delivery over ROUTE or MMTP
  • App-based service delivery over ROUTE
  • Electronic Service Guide (ESG) delivery over ROUTE
  • Emergency Alert Information (AEA) delivery over ROUTE
  • ATSC 3.0 signaling tables generation


Delivery of live HEVC encoders

ATSC3.0 has defined HEVC as the video encoding format. The ATSC3.0 encoders generate either DASH or MPU segments containing all the audiovisual content. Then, MediaCast can interface with multiple encoders and aims at delivering DASH segments over a ROUTE IP stream and MPU segments over a MMTP IP stream.

Non-real time service delivery

Non-real Time (NRT) services are applications generated by data server for delivering Electronic Service Guide (ESG), Emergency Alert Service (AEA), interactive applications or any kind of content to be download into the receiver. The MediaCast is designed to deliver NRT services over ROUTE protocol.

Service signaling

Service Signaling provides service discovery and description information. The Service List Table (SLT) enables the receiver to build a basic service list and bootstrap the discovery of the SLS for each ATSC 3.0 service. The SLT can enable very rapid acquisition of basic service information. The Service Layer Signaling (SLS) enables the receiver to discover and access ATSC 3.0 services and their content components. The MediaCast aims at generating both SLT and SLS and delivering them over ROUTE and MMTP protocols.
