Abstract

Se describe un mecanismo de codificación de video. El mecanismo incluye particionar una imagen en una pluralidad de mosaicos de primer nivel. Un subconjunto de los mosaicos del primer nivel se divide en una pluralidad de mosaicos de segundo nivel. Los mosaicos de primer nivel y los mosaicos de segundo nivel se asignan en uno o más grupos de mosaicos de modo que todos los mosaicos de segundo nivel creados a partir de un único mosaico de primer nivel se asignan a un mismo grupo de mosaicos. Los mosaicos de primer nivel y los mosaicos de segundo nivel se codifican en un flujo de bits. El flujo de bits se almacena para su comunicación con un decodificador.
