Detailed Description
A class specially for coding the DC subband of Intra frames, using intra-band prediction of coefficients.
Constructor & Destructor Documentation

-
| bits_out | the 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 |
