Abstract
A digital video encode system, method and computer program product are described wherein a picture is divided into multiple active areas that are parallel encoded using multiple encoders. The encoders associated with adjoining active areas of the picture are configured to exchange reference data to facilitate avoiding appearance of a seam between the adjoining active areas of a subsequent picture in a sequence of pictures due to separate encoding thereof by the multiple encoders. The reference data transferred from one encoder to an adjoining encoder is an encoded and decoded section of the picture and is used by the adjoining encoder as an expanded reference area for motion estimation when encoding the subsequent picture.
