Embodiments are directed towards providing extended Advanced Television Systems Committee (ATSC) 3.0 compliant content. An ATSC 3.0 extension device receives ATSC 3.0 compliant content and other data via a broadband communication. The ATSC 3.0 extension device broadcasts the ATSC 3.0 compliant content via ATSC 3.0 data signals and broadcasts the other data via 5G data signals. A user device receives the ATSC 3.0 compliant content via the ATSC 3.0 data signals and receives the other data via the 5G data signals. The user device combines and outputs the ATSC 3.0 compliant content with the other data for presentation to a user.
