Abstract

resumo “parâmetros de decodificador de referência hipotético em codificação de vídeo” um dispositivo realiza uma operação de decodificador de referência hipotético (hrd) que determina a conformidade de um fluxo de bits a um padrão de codificação de vídeo ou determina a conformidade de um decodificador de vídeo com o padrão de codificação de vídeo. como parte de realizar a operação de hrd, o dispositivo determina um maior identificador temporal de um subconjunto de fluxo de bits associado com um ponto de operação selecionado do fluxo de bits. além disso, como parte da operação de hrd, o dispositivo determina, com base no maior identificador temporal, um elemento de sintaxe particular dentre uma matriz de elementos de sintaxe. o dispositivo, em seguida, usa o elemento de sintaxe particular na operação de hrd. 1/1
