Hi William,
Annex I does do DC/AC prediction.  However Annex K is not data partitioning,
it is Slice Structure Mode which similar to MPEG slices.

  Hi,
    As far as I can remember, H.263++ also support
  DC/AC prediction (Annex I )
  data partitioning  (Annex K )

Hi Sudhakar,
    MPEG-4 is built over H.263. MPEG-4 has adopted the core compression
efficiency tools from H.263 like unrestricted motion vector, 4 MV etc.
The additional tools of MPEG-4 are adaptive AC/DC prediction, resync
markers, data partitioning, RVLC, non-linear quantization of DC
coefficients, supporting separate VLC table for Intra macroblocks etc.
These comparisons are between MPEG-4 simple profile and H.263 only.
