Abstract
Described herein is a system and method for encoding video data with motion estimation. The system and method can optimize memory usage and enhance the perceptual quality of an encoded picture by combining the processes in adaptive frame/field coding.
Claims12
A method for video encoding, said method comprising:
- selecting a candidate picture set from a set of reference pictures, wherein the selection is based on a field motion estimation of a current picture;
- determining a cost for field motion estimation in the current picture with respect to the candidate picture set;
- determining a cost for frame motion estimation in the current picture with respect to the candidate picture set;
- and
- selecting a preferred motion estimation mode based on the cost for field motion estimation and the cost for frame motion estimation.
2 more elements
A video encoder with motion estimation, said video encoder comprising:
- a coarse motion estimator for selecting a plurality of candidate pictures for motion estimation of a field in a current macroblock;
- a fine motion estimator for computing two or more motion vectors for the current macroblock with respect to the plurality of candidate pictures, wherein the motion vectors comprise at least one field mode motion vector and at least one frame mode motion vector;
- and
- a classification engine for selecting a motion estimation mode based on the motion vectors, wherein the motion estimation mode is selected from a set containing a frame mode and a field mode.
1 more element
A integrated circuit for video encoding with motion estimation, said integrated circuit comprising:
- arithmetic logic operable to select a plurality of candidate pictures, wherein said plurality of candidate pictures is used to generate one or more frame mode motion vectors and one or more field mode motion vectors;
- and
- memory for storing the plurality of candidate pictures.
