This paper researches a next-generation ultrahigh-definition television (UHDTV) broadcasting system. The video parameters of UHDTV systems with 120 frame/sec signals are specified in the Recommendation of the International Telecommunications Union Radiocommunication Sector, broadcasting service (television) series 2020. In this study, a new mapping method was developed to transmit various UHDTV signals, including 120 frame/sec signals. A prototype interface for connecting UHDTV video devices was also developed. The method is to transform UHDTV signals into multilink 10 Gbit/sec streams. The number of 10 Gbit/sec streams differs according to the UHDTV format (frame frequency, pixel count, and sampling lattice). To realize a compact and low-power interface, the prototype using a parallel fiber-optic transceiver with a capacity of 10 Gbit/sec per channel was implemented. Finally, the practicality and feasibility of the multilink 10 Gbit/sec mapping method and the prototype interface was verified.
