Abstract

método de processamento de dados de vídeo, aparelho para processar dados de vídeo, meio de armazenamento e meio de gravação não transitórios legíveis por computador. um método para processar mídia visual inclui determinar, para uma conversão entre um primeiro bloco de vídeo de dados de mídia visual e uma representação de bitstream dos dados de mídia visual, uma disponibilidade de um segundo bloco de vídeo dos dados de mídia visual usando uma regra; e desempenhar a conversão com base na determinação, em que a regra é pelo menos baseada em um modo de codificação usado para codificar o primeiro bloco de vídeo na representação de bitstream, em que a regra especifica impossibilita que informações de movimento do segundo bloco de vídeo sejam usadas em uma construção de lista de fusão do primeiro bloco tratando o segundo bloco de vídeo como indisponível.
