Abstract

The invention discloses a method and equipment for multi-channel digital sound playback. The user can enjoy multi-channel music calibrated to properly match the user's location. The apparatus includes a sound signal generation unit for generating a digital sound signal from multi-channel sound resource data, and a channel calibration unit for storing a channel calibration matrix set by a control signal generated based on user's position information, using the The stored matrix calibrates the multi-channel sound signal and carries the calibrated sound signal to a plurality of speakers. A multi-channel digital sound playback method includes generating a multi-channel sound signal from multi-channel sound resource data, and setting a channel calibration matrix based on user's position information input by a user and calibrating the multi-channel sound signal using the set matrix Then carry the calibrated multi-channel sound signal to multiple speakers.

Description

technical field [0001] The present invention relates to a method and apparatus for playing multi-channel digital sound, and more particularly, to a method and apparatus for playing multi-channel digital sound that can change characteristics of a speaker based on a user's position. Background technique [0002] Recently, home theater systems have become popular. Home theater systems include television and video equipment designed to reproduce in the home what is then seen in a movie theater. The term "home theater" was used even before digital versatile disk (DVD) players became common, but it has become popular when DVD players have become more common. DVD players provide users with more ambient sound than traditional audio systems such as Laser Disc (LD) players, Video Home Systems (VHS), and Video Compact Disc (VCD) players. For example, when a scene from the movie "Saving Private Ryan, 1998" in which a bullet is fired forward is played on the scr...
