    摘要: The invention is directed to a method and apparatus for providing temporal scaling frames for use in digital multimedia. The method involves using a removable unidirectional predicted temporal scaling frame communication along with intra-coded frames and/or inter-coded frames. The method involves the ability to selectively remove the temporal scaling frame(s) from being transmitted or decoded in order to satisfy, for example, power limits, data rate limits, computational limits or channel conditions. Examples presented include encoders, transcoders and decoders where the decision to drop the removable temporal scaling frames could be made.

    摘要: In general, this disclosure describes encoding and decoding techniques that facilitate more accurate interpolation of skipped video frames. In particular, techniques are described for obtaining motion information that indicates motion for skipped video frames based on translational motion and at least one other motion parameter and applying the motion information to interpolate the skipped video frames. The motion information may, for example, indicate motion based on a motion model that models three or more motion parameters as opposed to conventional two parameter translational motion vectors. The more accurate motion information may either be generated within the decoder performing the interpolation or be transmitted by an encoder in one or more frames. Either way, the techniques reduce the amount of visual artifacts in the interpolated frame.

    摘要: 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.
