Abstract

Para mejorar la eficiencia de codificación en la codificación y transmisión de datos de la imagen de una capa base y una capa mejora. Los datos de la imagen de cada imagen de la capa base se codifican para generar un primer flujo codificado. Los datos de la imagen de cada imagen de la capa de mejora se codifican para generar un segundo flujo codificado. Un contenedor que incluye los flujos se transmite. Una imagen de la capa base se puede utilizar como una imagen de referencia en la codificación de los datos de la imagen de cada imagen de la capa de mejora, y el procesamiento de la conversión para hacer que los datos de la imagen de la capa base se correspondan con los datos de la imagen de la capa de mejora se aplica a un bloque de la imagen de referencia para realizar el procesamiento de codificación de predicción de compensación de movimiento cuando la imagen de la capa base se utiliza como la imagen de referencia.
