Development of a Multi-Link 10-Gbit/s Mapping Method and Interface Device for 120-fps UHDTV Signals
We are currently researching Super Hi-Vision (SHV) as a next-generation ultra high definition television (UHDTV) broadcasting system. The video parameters of UHDTV systems with 120 frames-per-second (fps) signals are specified in Recommendation ITU-R BT.2020. — In this study, we have developed a new mapping method to transmit various UHDTV signals, including 120-fps signals, and we have developed a prototype interface for connecting UHDTV video devices. — The method is to transform UHDTV signals into multi-link 10-Gbit/s streams. The number of 10-Gbit/s streams differs according to the UHDTV format (frame frequency, pixel count, and sampling lattice). To realize a compact and low-power interface, we implemented the prototype using a parallel fiber-optics transceiver with a capacity of 10-Gbit/s per channel. Finally, we verified the practicality and feasibility of the multi-link 10-Gbit/s mapping method and the prototype interface.
