Abstract

um dispositivo exemplar para decodificar dados de vídeo inclui uma memória configurada para armazenar dados de vídeo e um ou mais processadores implementados em circuidade e configurados para determinar um valor máximo possível para um elemento de sintaxe de transformação secundária para um bloco de dados de vídeo, decodificação por entropia de um valor para o elemento de sintaxe de transformação secundária do bloco para formar um valor binarizado representativo da transformação secundária para o bloco, binarização reversa do valor para o elemento de sintaxe de transformação secundária usando um esquema de binarização comum, independentemente do valor máximo possível para determinar a transformação secundária para o bloco e coeficientes de transformada inversa do bloco usando a transformação secundária determinada.
