Abstract

CODIFICAçãO DE VIDEO ESCALONáVEL COM ENCODIFICAçãO DE DUAS CAMADAS E DECODIFICAçãO DE úNICA CAMADA. Algumas modalidades compreendem um método para decodificar um fluxo de bits de video que inclui receber uma primeira camada de dados e uma segunda camada de dados, combinar os dados recebidos da primeira camada e os dados da segunda camada recebida e decodificar os dados combinados. Além disso, um método para encodificar vídeo que inclui selecionar dados para encodificação em uma primeira camada e em uma segunda camada de modo a permitir a decodificaçào dos dados em uma única camada combinada, e encodificar os dados selecionados na primeira camada e na segunda camada mediante encodificação de um coeficiente na primeira camada e encodificação de um refinamento diferencial para o coeficiente da primeira camada na segunda camada.
