Abstract

Un método de codificación de video con respecto al formato de submuestreo de croma 4:2:2 comprende dividir los datos de imagen en unidades de transformación; en el caso de una unidad de transformación no cuadrada, dividir la unidad de transformación no cuadrada en bloques cuadrados antes de aplicar la transformación de frecuencia espacial; y aplicar la transformación de frecuencia espacial a los bloques cuadrados para generar conjuntos de coeficientes de frecuencia espacial.
