Patent ID: 7995649

Claim:
In a video encoder, a method comprising: identifying a current smooth region of a current video picture in a video picture sequence, the video picture sequence having a display order in which display of plural previous pictures occurs before display of the current video picture in the display order and display of plural future pictures occurs after the display of the current video picture in the display order; performing temporal analysis on the current smooth region, wherein the temporal analysis comprises determining whether a corresponding region in at least one of the plural previous and/or future pictures is smooth wherein the temporal analysis attributes greater weight to smoothness in a corresponding region of a future picture that is temporally nearer to the current video picture than to smoothness in a corresponding region of a future picture that is temporally more distant from the current video picture; based at least in part on the temporal analysis, adjusting quantization in the current smooth region; and outputting encoded data for the current video picture.
