1. An apparatus for receiving moving-image data from a part of a plurality of encoders that encodes captured moving image, and distributing the received moving-image data to a client terminal, the apparatus comprising: a moving-image-data acquiring unit that acquires, when a failure occurs in other moving-image distributing apparatus, a plurality of moving-image data transmitted from a part of the encoders to the other moving-image distributing apparatus; an imaging-target-information acquiring unit that acquires location information of an imaging target from a management server that manages the location information of the imaging target; and an encoder selecting unit that selects the encoder to take charge in place of the other moving-image distributing apparatus, based on encoder location information included in the moving-image data and the location information of the imaging target.
