摘要：A method and an apparatus for encoding media data and metadata thereof are provided to increase the range that a data region having limited space inside metadata is able to indicate. A metadata coding apparatus generates a scale indicator inside metadata(210), and the scale indicator is an indicator which defines the scale of information that a data region of current metadata. The metadata coding apparatus allocates field classifiers which classifies the scale indicator and the boundary of the data region(220). The metadata coding device determines a data region which has values different from each other according to the scale indicator(230).
