Abstract

resumo método de determinação de palavras de código binárias para coeficientes de transformada um sistema é fornecido para a criação de parâmetro de nível atualizando palavras de código para transformar coeficientes utilizados para relacionar unidades de transformada (tus) que dividem unidades de codificação (cus) em um sistema de codificação de vídeo de alta eficiência (hevc). o sistema fornece binarização das palavras de código e remove operações desnecessárias para reduzir a complexidade do sistema e aumentar o desempenho de compressão. o sistema gera coeficientes de transformada que relacionam as tus e começa por fornecer uma variável de parâmetro (criceparam) definida para um valor inicial de zero. a variável de parâmetro é então convertida em uma palavra de código binária com base no valor atual da variável de parâmetro e o valor de um símbolo e, em seguida atualizada com um novo valor atual depois de cada símbolo ter sido convertido. a atualização pode ser fornecida com referência aos valores de tabela ou os valores podem ser fornecidos a partir de lógica de combinação.
