Abstract

derivação de contexto para codificação de última posição para codificação de vídeo. em um exemplo, um dispositivo inclui um codificador de vídeo configurado para determinar um contexto para codificação por entropia de um compartimento de um valor indicativo de um último coeficiente significante de um bloco de dados de vídeo utilizando uma função de um índice do compartimento, e codificar o compartimento utilizando o contexto determinado. o codificador de vídeo pode codificar ou decodificar o compartimento utilizando codificação aritmética binária adaptativa de contexto (cabac). a função também pode depender do tamanho do bloco. dessa forma, uma tabela indicando os índices de contexto para os contextos não precisa ser armazenada pelo dispositivo.
