FRONT WAVE FIELD SYNTHESIS (WFS) SYSTEM AND METHOD FOR PROVIDING SURROUND SOUND USING 7.1 CHANNEL CODEC

摘要

Provided is a system and method for front wave field synthesis (WFS) to provide a surround sound with a reduced number of loudspeakers. An apparatus for encoding a front WFS signal in the front WFS system may include a content receiving unit to receive WFS content including the first channels corresponding to a front array speaker and the second channels corresponding to a rear surround sound speaker, and an encoding unit to encode the first channels and the second channels using a multichannel encoder corresponding to the number of the channels included in the WFS content.
