Abstract
método de predição de movimento e método de codificação de vídeo. a invenção fornece um método de predição de movimento. primeiro, são obtidos diversos preditores de vetores de movimento para serem incluídos em um conjunto de candidatos para predição de movimento de uma unidade corrente de um quadro corrente. é em seguida determinado se o quadro corrente é um quadro sem referência que não é referido por outros quadros para predição de movimento. quando o quadro corrente não for o quadro sem referência, qualquer preditor de vetor de movimento correspondente a um quadro previamente codificado é removido do conjunto canditado, e é predito um vetor de movimento da unidade corrente de acordo com os preditores de vetores de movimento do conjunto de candidatos.
