ATSC 3.0 IP.. ATSC 3.0. ATSC 3.0 UHD. Abstract UHD broadcasting based on ATSC 3.0 is being implemented in Korea, and discussion on mobile broadcasting based on ATSC 3.0 is underway. The ATSC 3.0 standard introduces internet protocol based standards in order to facilitate the implementation of conventional broadcasting services as well as broadcasting and communication convergence services interlocking with communication services. In this process, various requirements for the receiver have been derived, and factors to consider for developing the receiver product have also increased. ATSC 3.0 broadcasting is currently in the introduction stage of the service, and additional technology development and product implementation related to the receiver should proceed until the full-scale market is formed. In this regard, this paper describes the considerations for developing UHD receiver based on ATSC 3.0 and the test procedure for verifying developed receiver.
