Abstract
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.
Claims17
An apparatus for encoding a front wave field synthesis (WFS) signal, the apparatus comprising:
- 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.
An apparatus for decoding a front wave field synthesis (WFS) signal, the apparatus comprising:
- a decoding unit to decode multiple channels in a WFS signal using a multichannel decoder;
- a channel classifying unit to classify the decoded channels into the first channels corresponding to a front array speaker and the second channels corresponding to a rear surround sound speaker;
- and
- a channel transmitting unit to transmit each of the channels to the speaker corresponding to the channel based on the classified result.
A front wave field synthesis (WFS) system comprising:
- an encoding apparatus to encode six the first channels corresponding to a front array speaker including six loudspeakers and two the second channels corresponding to a rear surround sound speaker including two discrete loudspeakers, using a 7.1 channel encoder;
- and
- a decoding apparatus to decode the first channels and the second channels in a received signal using a 7.1 channel decoder and to transmit each of the channels to the speaker corresponding to the channel.
A method for encoding a front wave field synthesis (WFS) signal, the method comprising:
- receiving WFS content including the first channels corresponding to a front array speaker and the second channels corresponding to a rear surround sound speaker;
- and
- encoding the first channels and the second channels using a multichannel encoder corresponding to the number of the channels included in the WFS content.
