Abstract:
1. A method comprising: receiving wavelet information associated with encoded frames of a multimedia sequence; decoding the encoded frames of the multimedia sequence; and interpolating additional frames between the decoded frames based on the wavelet information; wherein the wavelet information comprises low frequency wavelet information, high frequency wavelet information and motion information, wherein the motion information comprises a plurality of motion fields, at least one of the motion fields being derived from another of the motion fields, wherein decoding the encoded frames comprises decoding a low frequency frame associated with the low frequency wavelet information and a high frequency frame associated with the high frequency wavelet information into two decoded low frequency frames, and wherein interpolating additional frames between the decoded frames comprises interpolating two or more low frequency frames based on the two decoded low frequency frames and linear motion trajectories representing motion between the two decoded low frequency frames.
