One of the promises of ATSC 3.0 has been the potential for data offload. Separately, advances have been made over the last year in hybrid and IP channel rollouts on ATSC 3.0. We have taken advantage of this to combine the two in order to architect an implementation of that data offload system. In this paper, we will explore a practical hybrid delivery model for streaming video services, allowing the distribution of video over CDNs and simultaneously over 3.0, drastically decreasing the bandwidth needs of these CDNs in 3.0 markets, all while integrating into third party streaming apps to enable seamless streaming with no change to the viewer experience. Topics covered will include the methodology on synchronization, encoding needs for the CDN, airchain and signaling design, integration into a streaming application, and the results of the real world testing of this system.
