Abstract
em uma implementação particular, um decodificador de vídeo pode refinar um preditor de vetor de movimento inicial decodificado a partir do fluxo de bits para um bloco atual. a fim de reduzir o overhead de sinalização, o decodificador pode determinar se refinamento de movimento é usado ou não com base na informação que já está disponível, por exemplo, com base em se o campo de movimento é uniforme ao redor do bloco atual, e se existe um certo nível de textureness em blocos adjacentes. a diferença de vetor de movimento decodificada a partir do fluxo de bits pode ser usada para automaticamente ativar ou desativar o refinamento de movimento sem receber sinalização explícita no fluxo de bits. por exemplo, quando a diferença de vetor de movimento é menor do que um limite, o refinamento de movimento é automaticamente ativado, e quando a diferença de vetor de movimento é maior do que outro limite, refinamento de movimento é automaticamente desativado. um codificador de vídeo correspondente pode escolher se usar e sinalizar refinamento de movimento com base em decisões do codificador.
