Abstract

trata-se de um dispositivo de conversão de vídeo em código que inclui uma memória configurada para armazenar dados de vídeo e um processador (ou processadores) configurados para processar pelo menos uma porção dos dados de vídeo armazenados. o processador (ou processadores) é configurado para identificar um grupo de coeficientes (cg) que inclui um coeficiente de transformada atual dos dados de vídeo, sendo que o cg representa um subconjunto de coeficientes de transformada dentro de uma unidade de transformada. o processador (ou processadores) são configurados adicionalmente para determinar um tamanho do cg com base em uma combinação de um tamanho de transformada e um ou ambos dentre (i) um modo de conversão em código associado à unidade de transformada, ou (ii) uma matriz de transformada associada à unidade de transformada.
