- This paper presents Internet protocol (IP)-based convergence of broadcast and broadband networks using Advanced Television Systems Committee (ATSC) 3.0-the next generation terrestrial broadcasting standard. In the broadcast network, the combination of Layered Division Multiplexing (LDM) and Scalable High Efficiency Video Codec (SHVC) is used, enabling efficient use of spectrum when mobile and fixed services are intended in a single radio frequency (RF) channel. The proposed use case of IP-based convergence is that a service is largely consumed through the high power high tower (HPHT) based broadcast network, and then alternative streams are requested via unicast for areas where broadcast signals are not receivable. The implementation details of broadcast and broadband convergence include MPEG Media Transport (MMT)/Real-time Objective delivery over Unidirectional Transport (ROUTE) description for broadcast useand Dynamic Adaptive Streaming over HTTP (DASH) for broadband use. To achieve seamless convergence between broadcast and broadband, transmission and reception systems based on ATSC 3.0 are hardware-developed and their implementation details are described. The proposed IP-based convergence use case of ATSC 3.0 broadcast and broadband is verified in a real-field environment using a public cellular network.
