A method and apparatus to process erroneous bi-directionally predicted
multimedia data is described. The method includes determining temporal
prediction data for the erroneous multimedia data, and estimating the
erroneous multimedia data based on the determined temporal prediction
data. The temporal prediction data includes data that was used to predict
a forward reference section and/or a backward reference section. In some
aspects, the temporal prediction data comprises motion vector data of the
reference frames which is scaled to correspond to a frame containing the
erroneous data.
