Minimizing drift in motion-compensation fine granular scalable structures

An apparatus for coding video, the apparatus comprising:

• means for measuring motion activity within at least a portion a video;
• means for determining whether the measured motion activity is below a predetermined threshold value;
• means for coding the portion of the video with a fine granular scalable video coding scheme that utilizes motion compensation in an enhancement layer if the measured motion activity is below the predetermined threshold value;
• and
• means for coding the portion of the video with a fine granular scalable video coding that does not utilize motion compensation in an enhancement layer if the measured motion activity is above the predetermined threshold value.
