Abstract
In order to enable efficient utilization of an available bandwidth by properly estimating the available bandwidth under conditions in which the available bandwidth significantly changes upon occurrence of communication path switching, an available bandwidth estimation is performed by estimating a current available bandwidth based on historical communication state information i.e. information on a past communication state stored in a storage to control a code amount used in encoding an image; upon occurrence of communication path switching (handover), acquiring a temporary available bandwidth value corresponding to a new (post-handover) communication path; generating new communication state information corresponding to a new communication state based on the temporary available bandwidth value; replacing the historical communication state information stored in the storage with the new communication state information; and estimating a new available bandwidth based on the new communication state information stored in the storage.
