This part of ISO/IEC 14496 specifies how tests can be designed to verify whether compressed data and

decoders meet requirements specified by ISO/IEC 14496-3. In this part of ISO/IEC 14496, encoders are not

addressed specifically. An encoder may be said to be an ISO/IEC 14496 encoder if it generates compressed

data compliant with the syntactic and semantic bitstream payload requirements specified in ISO/IEC 14496-3.
