Abstract:
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 16×16 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.
