Abstract

"CONTROLE DE TAXA DE VìDEO MULTIPASSE PARA CASAR RESTRIçõES DE CANAL DE JANELA DESLIZANTE". São revelados um codificador (100) e método correspondente (200) para realizar controle de taxa de vídeo para atender restrições do modelo de tráfego de rede, incluindo pré-codificar a seqüência de imagens para cada um de uma pluralidade de valores de parâmetros de quantização, selecionar, para cada imagem da seqüência, um da pluralidade de valores de parâmetros de quantização responsivos aos valores de parâmetros de quantização e pontos operacionais de taxa de bits das imagens vizinhas na janela de tempo deslizante, e codificar cada imagem da seqüência usando o valor de parâmetro de quantização selecionado para essa imagem.
