This paper presents Advanced Television Systems Committee (ATSC) 3.0 and 4th Generation (4G) Long-Term Evolution (LTE) cooperation trials for high-quality and reliable mobile broadcasting services. Given the ATSC 3.0 based Layered Division Multiplexing (LDM) and Scalable High Efficiency Video Codec (SHVC) configuration, which is the most spectral-efficient broadcast mode when mobile and fixed services are intended in a single radio frequency (RF) channel, the convergence of broadcast and broadband in the Internet protocol (IP) level is developed and field experimented. Service scenarios in a real field environment includes Base Layer (BL) and Enhancement Layer (EL) switching in a broadcast coverage, switching between broadcast and broadband networks, and hybrid services using both broadcast and broadband networks.
