Abstract

Un aparato para codificar datos de video de acuerdo con ciertos aspectos incluye una memoria para almacenar los datos de video y un procesador. La memoria incluye un búfer. El procesador está configurado para recibir los datos de video a ser codificados. El procesador además está configurado para determinar un parámetro de cuantificación (QP) de un bloque actual de los datos de video sin consideración de un tipo de contenido de los datos de video y un modelo de tasadistorsión asociado con el tipo de contenido. El procesador también está configurado para codificar el bloque actual en un flujo de bits utilizando el QP determinado.
