NHK has developed a 22.2 multichannel sound system for 8K Super Hi-Vision (SHV), an ultra high-definition TV. The system consists of 24 spatially arranged audio channels including two low frequency effect channels for reproducing three-dimensional spatial sound. To respond to various viewing circumstances of SHV in homes, we have also developed several reproduction methods to virtually reproduce 22.2 multichannel sound with fewer loudspeakers. In this paper, we propose binaural reproduction of 22.2 multichannel sound with multiple loudspeakers integrated into a flat panel display, which makes it possible for us to experience 22.2 multichannel sound without installing 24 discrete loudspeakers.
