Abstract

método e sistema escalonável para extração de fluxo de bits é fornecido um sistema de compressão de vídeo escalonável (100) tendo um codificador (120), um extrator de bit (140), e decodificador (160) para codificar e decodificar com eficiência um fluxo de bits embutido escalonável ( 13 o) em velocidade de quadro, diferentes resoluções de vídeo, e níveis de qualidade de vídeo. os bits podem ser extraídos em ordem de camada de refinamento (136), seguido pelo nível temporal (132), seguido pela camada espacial (134), em que cada bit extraído fornece um melhoramento incremental na qualidade da decodificação do vídeo. a extração de bit pode ser truncada em uma posição no fluxo de bits embutido correspondente a uma camada de refinamento máximo, um nível temporal máximo, e uma camada espacial máxima. para uma camada de refinamento dada, os bits são extraídos de todas as camadas espaciais em um nível temporal mais baixo antes de extrair bits de camadas espaciais em um nível temporal mais alto para priorizar o ganho de codificação para aumentar a qualidade da decodificação do vídeo, e antes de passar para uma próxima camada de refinamento.
