Study of development of transmission systems for terrestrial 4K UHD & HD convergence broadcasting

In this paper, the service scenario & requirements for providing 4K UHD & HD convergence broadcasting services through terrestrial single channel are analyzed by employing the latest transmission and A/V codec technologies. Optimized transmission parameters for 6 MHz & 8 MHz terrestrial bandwidths are drawn, and receiving performances are measured under Additive White Gaussian Noise (AWGN) and time-varying multipath channels.
