** Standardized compliance test data is used to perform the encoder and decoder compliance tests.**

There are two types of compliance test data which are used by the encoder compliance tests: source image test data and encoder reference test data.

Similarly, there are two types of compliance test data which are used by the decoder compliance tests: compressed test data and decoder reference test data.
