  Abstract

8K UHD Signal generation system is essential for expanding 8K UHD broadcasting service. In particular, TV manufacturers are demanding a system that supports higher quality video than general broadcasting to promote new TV. The research on the 8K signal generation system is based on a method of parallelizing for processing data by 4 times the number of pixels compared to 4K. As a commercially available solution, a system that supports uncompressed video is capable of high video quality by linking 4K signal generation system to play 4 segmented uncompressed video and to output 4 HDMI 2.0 standard, but it is unsuitable as a promotional system that uses multiple videos due to excessive demand for storage space. A system that supports compressed video cannot support the high picture quality required by TV manufacturers because developed for 8K broadcasting service. Therefore, it is inevitable to implement a signal generation system that supports compressed video based on parallel processing and synchronization between multiple video streams and display output signal level synchronization are required. In this paper, We designed and implemented an 8K UHD signal generation system combining four 4K signal generation systems and one-chip FPGA capable of high-speed video processing. The system supports synchronous playback of four divided video and four HDMI 2.0 for output that is synchronized up to the signal level. Experimental results show that the proposed system supports more than 8 times higher bit-rate than the commercialized system, saves storage space to 1/20, and supports screen output up to 8K60p.
