Title: TIME SERIES DATA ENCODING APPARATUS, METHOD, AND PROGRAM, AND TIME SERIES DATA RE-ENCODING APPARATUS, METHOD, AND PROGRAM
Abstract:
 The present invention is provided with: a time series data encoding means (11) for compression-encoding time series data and generating an encoded bitstream; a virtual buffer (12) for calculating the change in the amount of data stored in the buffer of a virtual encoder specified according to an encoding method; a buffer use amount analysis means (13) for analyzing the change in the amount of stored data and resetting the parameters that represent the size of the buffer and the amount of stored data at a prescribed time in the buffer; an encoded bitstream generated by the time series data encoding means (11); and a multiplexing means (14) for multiplexing the parameters reset by the buffer use amount analysis means (13).
