Abstract
A method includes intra-refresh encoding each picture of a first set of pictures such that a position of a refresh region for the picture is spatially shifted relative to the position of the refresh region for a previous picture of the first set responsive to determining global motion associated with the first does not exceed a specified threshold. The method further includes intra-refresh encoding each picture of a second set of pictures such that a position of a refresh region for each picture of the second set is fixed to be immediately adjacent to a picture edge that is in a direction of global motion associated with the second set responsive to determining the global motion associated with the second set exceeds the specified threshold.
