NHK has been developing Super Hi-Vision (SHV), an ultrahigh-definition TV system that has a 7,680 x 4,320 pixel video image and a 22.2 multichannel three-dimensional sound system. A loudspeaker array frame (LAF) integrated into a flat panel display can synthesize wavefront of frontal sound source and localize sound images on the display and back of the viewer by using technology to simulate sound propagation characteristics. This makes it possible to listen to 22.2 multichannel sound without installing 24 discrete loudspeakers surrounding the listener in the room. In this paper we describe the prototype of the LAF and its performance focusing on frontal sound reproduction.
