ATSC 3.0 and TV 3.0 in the Cloud 

The transition to ATSC 3.0 and TV 3.0 enables broadcasters to leverage cloud infrastructure for traditional broadcast workflow. This paper presents a comprehensive reference architecture for implementing ATSC 3.0 and TV 3.0 systems on Amazon Web Services (AWS). The architecture addresses key challenges in networking and high availability requirements for broadcast operations. We demonstrate solutions for multicast routing in Virtual Private Clouds using AWS Transit Gateway, reliable Studio-to-Transmitter Link Transport Protocol (STLTP) delivery over public internet using Automatic Repeat reQuest (ARQ) protocols, and hybrid delivery optimization using Content Delivery Networks. Our implementation achieved zero packet loss during multiple tests ranging from 5 to 13 days between different AWS regions using Secure Reliable Transport (SRT) and Reliable Internet Stream Transport (RIST) protocols. Maximum round-trip times averaged 153 ms across continental distances. The architecture supported the continuous operation of commercial broadcast software, including encoders, ROUTE servers, and ATSC 3.0 gateways, while maintaining broadcast-grade reliability. Results from field testing validate the feasibility of cloud-based ATSC 3.0 implementations, providing broadcasters a blueprint for migration from traditional infrastructure while optimizing operational costs and maintaining security compliance for 24/7 broadcast operations.
