In a system for playing back a moving image constructed by a set of objects, each object is efficiency verified, and a problem of omission of a played back image due to delay time associated with verification processing is solved. On the transmission side, an MUX (201) generates an MPEG-4 bit stream obtained by coding a plurality of object and data streams constructing a moving image and IPMP (Intellectual Property Management and Protection) streams containing source information and use permission information into one stream. On the reception side, a DMUX (206) identifies and separates each stream from the MPEG-4 bit stream and separates them into a plurality of object data and source information/use permission information corresponding to each object data. On the basis of the separated source information/use permission information, an IPMP System (207) requests a corresponding server (202-204) to execute verification to access each object using a back-channel 1 (205) using an upstream or back-channel 2 (213) such as a telephone line. An access control point (212) is controlled to permit only access to object data for which an access permission signal has been received from the server. A signal for requesting resending objects is transmitted to the distribution server (202-204) of objects for which verification is requested, using the back-channel 1 (205) or 2 (213), together with the source information of the request destination server and information representing the verification result.
