Claim 7:
8. The method of claim 1, further comprising performing an intra-prediction estimation search based on a first subset of modes within a full set of modes specified for intra-prediction,
wherein performing the intra-prediction estimation search includes:
intra-predicting a third block based on a first mode in the first subset of modes, wherein a cost associated with predicting the third block with the first mode is lower than predicting the third block with other modes in the first subset of modes;
intra-predicting the third block with a second subset of modes within a first angle from the first mode; and
selecting a mode with a lowest cost from the first mode and modes in the second subset as a prediction mode for the third block, wherein a number of modes in the first subset of modes is less than a number of modes in the full set of modes.
