Abstract

DECODIFICADOR DE VÍDEO, CODIFICADOR DE VÍDEO, MÉTODO DE DECODIFICAÇÃO DE VÍDEO E MÉTODO DE CODIFICAÇÃO DE VÍDEO. Trata-se de um decodificador de vídeo que decodifica um fluxo codificado, que inclui uma parte de decodificação paralela por entropia para decodificar por entropia o fluxo de blocos nas linhas de blocos em paralelo, uma parte de previsão paralela de QP para computar valores de previsão dos blocos nas linhas de blocos em paralelo e uma parte de processamento de decodificação em paralelo para gerar pixels decodificados dos blocos nas linhas de blocos em paralelo, sendo que o pixel decodificado é obtido mediante a utilização de dados decodificados pela parte de decodificação paralela por entropia e o valor de previsão. Ao desempenhar o processamento de computação em paralelo por unidade de N linhas de blocos, o processamento é desempenhado em um bloco de processamento em uma linha de bloco (K-1)ésima, que precede um bloco de processamento em uma linha de bloco Késima em pelo menos um bloco em uma posição horizontal para computar o valor de previsão do bloco de processamento através da referência a um bloco já processado correspondente ao bloco de processamento.
