A method is provided for upsampling a received YCbCr signal. The method generates the missing chrominance coefficients for each individual pixel, with a view to converting the data in the RGB color space. The method takes into account the values of the chrominance coefficients actually received for a neighboring pixel, the values of the luminance of the pixel, and of the saturation value for chrominance coefficients, as dictated by the RGB boundaries at that value of the luminance of the pixel.

Um método é fornecido upsampling um sinal recebido de YCbCr. O método gera os coeficientes faltantes do chrominance para cada pixel individual, com uma vista a converter os dados no espaço de cor do RGB. O método faz exame no cliente dos valores dos coeficientes do chrominance recebidos realmente para um pixel neighboring, os valores do luminance do pixel, e do saturation avalie para coeficientes do chrominance, como ditado pelos limites do RGB nesse valor do luminance do pixel.
