A method of encoding time series data into a sound file, a method of decoding time series data from an encoded sound file, and a time series data input / output system using these methods
A method of encoding time series data into a sound file, a method of decoding time series data from an encoded sound file, and a time series data input / output system using these methods
PURPOSE: A method for encoding time-varying data in a sound file and a method for decoding time-varying data from a sound file and a system for inputting/outputting time-varying data using the same are provided to simultaneously supply sound information, time-varying operation information, or haptic feedback information. CONSTITUTION: An encoding unit receives time-varying data from a time-varying data generating unit(S10). Header data is generated based on inputted time-varying data(S20). The generated header data is coupled with the time-varying data(S30). The header data and the time-varying data are binarized(S40). A data change operation is applied to original sound data of a fixed original sound file based on the header data and the time-varying data to change the original sound data(S50). A changed sound file with the same format as the format of the original sound file is generated by coupling the changed sound data with a sound header(S60).
