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 
) [inline]

Creates a IntraDCBandCodec object to encode subband data, based on parameters

Parameters:
subband_byteio input/output for the encoded bits
number_of_contexts the number of contexts used in the encoding process
band_list the set of all the subbands
