Abstract

MÉTODO E APARELHO DE PROCESSAMENTO DE VÍDEO, MÉTODO PARA ARMAZENAR O FLUXO CONTÍNUO DE BITS DE UM VÍDEO, MÍDIA LEGÍVEL POR COMPUTADOR, E, FLUXO CONTÍNUO DE BITS. Um exemplo de método de processamento de vídeo inclui realizar uma conversão entre um bloco de um vídeo e um fluxo contínuo de bits do vídeo. O fluxo contínuo de bits se conforma com uma regra de formatação que especifica que um tamanho de uma região de estimativa de mescla (MER) é indicado no fluxo contínuo de bits e o tamanho da MER é com base em uma dimensão de uma unidade de vídeo. A MER compreende uma região usada para derivar um candidato de movimento para a conversão.
