Display apparatus having object-oriented 3D sound coordinate indication

摘要

A display apparatus having an object-oriented 3D sound coordinate indication is disclosed, in which sounds are outputted from a speaker positioned matching with a coordinate of an object in a matrix speaker apparatus formed of a plurality of small size speakers disposed behind a display apparatus in cooperation with an object content displayed on a display apparatus screen. The display apparatus having an object-oriented 3D sound coordinate indication comprises a center channel decoder which receives an audio signal corresponding to a center channel speaker among the audio signals outputted from a decoder of the surround speaker system and separates into sound sources based on an object; a center channel matrix for setting the coordinates of sound sources based on the objects separated by the center channel decoder; a matrix amplifier for amplifying an output sound of a speaker matching with each coordinate value of the sound sources based on the object; and a plurality of speakers which are arranged in a matrix shape behind the display monitor, whereby sounds are outputted through the speakers corresponding to the coordinates of the objects displayed on the display monitor.

1. An encoding system for encoding audio using an authoring tool, the encoding system comprising:
an X-Y-Z coordinate panner for inputting an X bus parameter and a Y bus parameter for setting X and Y coordinates, the X and Y coordinates corresponding to a speaker channel among a plurality of speaker channels which are arranged in a matrix shape behind a screen for a sound source of an object, and inputting a Z depth parameter for setting Z depth values indicating far and near effects of the object along with a Z axis; and a channel encoder for storing the X bus parameter, the Y bus parameter and the Z depth parameter which are inputted for the sound source of the object as data to output the data through an export of the authoring tool; the authoring tool providing an overlay mode for displaying positions of the sound source of the object on a video which is synchronized with the audio according to the X bus parameter and the Y bus parameter; the authoring tool marking the positions of the sound source of the object on the video which is synchronized with the audio according to the X bus parameter and the Y bus parameter using markers; and the authoring tool visually displaying shaped objects based on attenuation parameters, and controlling a number of the speaker channels for outputting the audio for an audio source of the object near the speaker channel corresponding to the position of the object, based on sizes of the shaped objects.
