Document Type and Number:
WIPO Patent Application WO/2022/259356
Kind Code:
A1
Abstract:
A transmission device 10 includes an SDI input unit 11 that receives multiple subpictures obtained by dividing a picture via multiple SDI links, a mapping management unit 12 that selects an ST2110 mapping method for mapping pixel data to a packet on the basis of combinations of SDI mapping methods for pixel data in SDI and RP2110-23 compliance indicators, and an ST2110 output unit 13 that stores the pixel data of the picture in the packet according to the ST2110 mapping method and outputs the packet. A reception device 30 includes an ST2110 input unit 31 that receives the packet containing the pixel data, a mapping management unit 32 that selects an SDI mapping method for mapping the pixel data to the multiple SDI links on the basis of the combination of the ST2110 mapping method and the RP2110-23 compliance indicator for the pixel data in the packet, and an SDI output unit 33 that outputs the pixel data of the picture via the multiple SDI links according to the SDI mapping method.
