Abstract

MÉTODO DE PROCESSAMENTO DE VÍDEO, APARELHO PARA PROCESSAMENTO DE DADOS DE VÍDEO, E, MEIOS DE ARMAZENAMENTO E DE GRAVAÇÃO LEGÍVEIS POR COMPUTADOR NÃO TRANSITÓRIOS. Dispositivos, sistemas e métodos para codificação de vídeo digital, que incluem métodos de interprevisão com base em sub-bloco, são descritos. Um método exemplar para processamento de vídeo inclui determinar, para uma conversão entre um bloco de vídeo atual e uma representação do fluxo contínuo de bits do vídeo, um máximo número de candidatos em uma lista de candidato de mescla com base em sub-bloco e/ou se adicionam-se candidatos de previsão do vetor de movimento temporal com base em sub-bloco (SbTMVP) na lista de candidato de mescla com base em sub-bloco com base em se a previsão do vetor de movimento temporal (TMVP) é habilitada para uso durante a conversão ou se um modo de codificação de referência de figura atual (CPR) é usado para a conversão, e realizar, com base na determinação, a conversão.
