Detailed Description

A class specially for coding the DC subband of Intra frames, using intra-band prediction of coefficients. It uses the abstract ArithCodec class


Constructor & Destructor Documentation

dirac::IntraDCBandCodec::IntraDCBandCodec ( SubbandByteIO subband_byteio,
size_t  number_of_contexts,
const SubbandList band_list
