Method of estimating coded block pattern and method of determining block mode using the same for moving picture encoder

摘要

Provided are a coded block pattern (CBP) estimating method which is performed using an average value and a dispersion value between blocks of CBPs in a moving picture encoder for IP-TVs (Internet Protocol-Televisions), and a block mode decision method, which can determine all block modes with only the first 16x16 block. Accordingly, since an additional operation for mode determination is not necessary, an amount of calculation and thus a calculation time can be remarkably reduced.
