Abstract

1/1 resumo "controle de faixadinâmico de dados intermediários no processo de nova amostragem" um aparelho para codificação de informação de vídeo de acordo com determinados aspectos inclui uma memória e um processador. a unidade de memória é configurada para armazenar informação de vídeo. o processador é configurado para obter informação de vídeo de camada de referência; amostrar ascendentemente a informação de vídeo de camada de referência em uma primeira dimensão para gerar uma saída intermediária; restringir a saída intermediária a uma profundidade de bit predeterminada; e amostrar ascendentemente a saída intermediária restringida em uma segunda dimensão, onde a segunda dimensão é ortogonal à primeira dimensão.
