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 de primer nivel se particionan en una pluralidad de mosaicos de segundo nivel. Cada mosaico de segundo nivel contiene un solo segmento rectangular de datos de imagen. 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 comunicación hacia un decodificador.
