We are developing a satellite broadcasting system with layered division multiplexing (LDM) transmission that multiplexes multiple modulation signals with different power levels in the same channel for providing services flexibly in accordance with the receiving quality. We developed wideband modulator and demodulator implementing the LDM for 21-GHz-band satellite broadcasting, and evaluated its transmission performance to compare with a computer simulation.
Moreover, a spatial scalable coding of the versatile video coding (VVC) combined with the LDM enable to provide multiple signals with different receiving characteristics and transmission parameter in the same channel, and switch image resolution dynamically in accordance with the receiving quality. In this report, we conducted a laboratory experiment transmitting 4K/8K video encoded hierarchically by the spatial scalable coding using the modem. |
