Abstract

En general, esta divulgación describe técnicas para codificar bloques de video utilizando un proceso de conversión de color-espacio; un codificador de video, tal como un codificador de video o un decodificador de video, puede determinar una profundidad de bit de un componente de luminancia de los datos de video y una profundidad de bit de un componente de crominancia de los datos de video; en respuesta a que la profundidad de bit del componente de luminancia es diferente de la profundidad de bit del componente de crominancia, el codificador de video puede modificar una o ambas de la profundidad de bit del componente de luminancia y la profundidad de bit del componente de crominancia de manera que las profundidades de bit son iguales; el codificador de video además puede aplicar el proceso de transformada de color-espacio en la codificación de los datos de video.
