Data Movement Reduction In Video Compression Systems

A method for construction of motion estimation area comprising of steps:

• replacing the non-overlapped search area between the new MB and old MB belonging to the old motion estimation area, by the non-overlapped search area between the new MB and old MB belonging to the new motion estimation area;
• keeping the overlapped-search area between the old MB and new MB intact.

A method for construction of motion estimation area comprising of steps:

• partially replacing the non-overlapped search area between the new MB and old MB belonging to the old motion estimation area, by the non-overlapped search area between the new MB and old MB belonging to the new motion estimation area;
• keeping the overlapped-search area between the old MB and new MB intact.

A method for construction of motion estimation area for consecutive horizontal MBs in which the non-overlapped search area, between the old MB and new MB, belonging to the new MB partially replaces the non-overlapped search area, between the old MB and new MB, belonging to the old MB.

A method for construction of motion estimation area for consecutive horizontal macroblocks (MBs) in which the non-overlapped search area, between the old MB and new MB, belonging to new MB completely replaces the non-overlapped search area, between the old MB and new MB, belonging to the old MB in which a cyclic memory structure is used.

A method for construction of motion estimation area for consecutive horizontal MBs in which when transitioning from the motion estimation area of one target MB to the motion estimation area of next target MB, the starting point in the search area is changed.

A technique for which the motion estimation search area is used for multiple target MBs.

A method for construction of pattern matching area comprising of steps:

• replacing the non-overlapped pattern matching area between the new target pattern and old target pattern belonging to the old pattern matching area, by the non-overlapped pattern matching area between the new target pattern and old target pattern belonging to the new pattern matching area;
• keeping the overlapped-search area between the old target pattern and new target pattern intact.

A method for construction pattern matching area comprising of steps:

• partially replacing the non-overlapped pattern matching area between the new target pattern and old target pattern belonging to the old pattern matching area, by the non-overlapped pattern matching area between the new target pattern and old target pattern belonging to the new pattern matching area;
• keeping the overlapped-search area between the old target pattern and new target pattern intact.

A method for pattern matching of consecutive horizontal patterns in which overlapped search area of previous frame for new target pattern with the search area of old target pattern, is not removed.

A method for pattern matching of consecutive horizontal patterns in which the non-overlapped search area of new pattern completely replaces the non-overlapped search area of the old pattern and a cyclic memory structure is used.

A method for pattern matching of consecutive horizontal patterns in which when transitioning from one target pattern to the next target pattern, the starting point in the search area is changed.

A technique for which a search area is used for multiple target patterns.
