Abstract

Patente de Invenção: <B>"APARELHO E MéTODO PARA CODIFICAçãO DE ENTROPIA DE áRVORE ZERO DE MULTIESCALA"<D>. Um aparelho (100) e um método concomitante são revelados para codificar árvores ondas pequenas para gerar fluxos de bits com graus flexíveis de qualidade e complexidade de escalabilidade espacial. O método de codificação por entropia de árvore zero (ZTE) é estendido para alcançar um método de codificação totalmente escalonável por implementar um esquema de codificação de árvore zero multiescala.
