Abstract
In encoding high-definition video signals, the method includes overlapping panels with a single row in the overlap, selecting the better-encoded one of the rows in the overlap, removing the unselected row, and merging bit streams from the panels. In deciding which one of the rows in the overlap is better encoded, a heuristic approach may be used, for example, a panel with the fewer bits, or with fewer errors or the panel as suggested by the motion vectors. Optionally, panels may be synchronized by copying the selected row in the overlap in place of the unselected row in the overlap.
