Abstract

A fast block-based motion frame interpolation (FMCI) and an adaptive frame skipping scheme (AFS) are proposed for the H.263/H.263+ decoder and encoder, respectively, in this research. The proposed FMCI decoder can successfully interpolate non-coded frames so that a video clip with skipped frames can be played without jerkiness. In the FMCI decoder, the block-based motion fields from the encoder are directly utilized to generate interpolated frames without performing further motion search. Thus, the computational complexity of the interpolation operation is significantly saved. With AFS, the encoder can adaptively choose the frame skip number based on the prediction result of the embedded FMCI. AFS generates a bit stream with a variable frame rate, which can increase the coding efficiency and enhance the performance of the FMCI interpolation at the decoder. FMCI works with any bit stream generated by the standard H.263/H.263+ encoder with or without incorporating AFS.
