1. A method comprising:

  • receiving barbell coded video data including at least one even-numbered frame of low-pass coefficients and at least one odd-numbered frame of high-pass coefficients;

    generating an even-numbered frame of decoded video data using inverse barbell lifting by generating a plurality of decoded pixels in the decoded even-number frame based at least in part on a sum of a low-pass coefficient in the even-numbered frame and a result of multiplication of a high-pass coefficient in an adjacent frame with a filtering parameter; and

    generating an odd-numbered frame of video data using inverse barbell lifting.
