Abstract

MODO DE ATUALIZAçãO DE RESOLUçãO REDUZIDA PARA CODIFICAçãO AVANçADA DE VìDEO é fornecido um codificador de vídeo, decodificador de vídeo e métodos de codificação e decodificação correspondentes para respectivamente codificar e decodificar dados de sinais de vídeo para uma fatia de imagem. O codificador de vídeo inclui um amostrador com menor taxa de amostragem de residual de previsão de fatia (645) para amostrar com menor taxa de amostragem um residual de previsão de pelo menos uma porção da fatia de imagem antes da transformação e quantização do residual de previsão. O decodificador de vídeo inclui um amostrador com maior taxa de amostragem de residual de previsão (715) para amostragem com maior taxa de amostragem um residual de previsão da fatia de imagem.
