AN AUDIO DATA PROCESSING METHOD, AN AUDIO SOURCE DATA INPUT METHOD AND A METHOD FOR TRANSFERING UNIT SIGNAL FRAME TO AUDIO EXTRACTION UNIT FOR VIDEO CONFERENCING

摘要

PURPOSE: A method for processing audio data for a video conference, audio source data input method and a method for transmitting a unit signal frame to audio data extraction unit are provided to represent audio of a plurality of dialogists as a stereo channel, and to simultaneously extract only an audio signal of a specific dialogist. CONSTITUTION: The number of dialogists who participate in a video conference and an input signal of a mike are inputted as an audio source(S1). Each weight value to be multiplied by an audio signal of a specific dialogist is calculated according to a virtual position array(S2). The weight value is reflected and loaded to a right and a left transmission channel(S3). It is extracted whether the specific dialogist is speaking(S4). Each relevant weight value is multiplied by the audio signal of the dialogist inputted for a unit time(S5). An audio signal having a virtual audio phase is compounded with a plurality of positions(S6). Header information and audio signal information are compounded(S7). A unit signal frame is transmitted to an audio data extraction unit(S8). It is judged whether data inputted is the final data(S9).
