The video predictive encoding device according to the present invention is equipped with an input means that inputs a plurality of images that constitute a video, and an encoding means that encodes the plur­ ality of images using either an intra prediction meth­ od or an inter prediction method, generates com­ pressed image data, and packetizes the compressed image data together with packet header information. The packet header information includes picture type. The encoding means determines the picture type to uniquely show whether an encoded picture data is used as a reference when decoding another picture.
