Abstract:
1. An information processing apparatus comprising: a receiver configured to receive a request message indicating a requested content identifier and a requested data range of a requested digital content, wherein the requested data range corresponds to a part of the requested digital content; a determiner configured to determine whether a digital content corresponding to the requested content identifier includes the requested data range; a decider configured to decide a content identifier and a data range of a digital content to be used when responding to the request message, based on a determination by the determiner; and a transmitter configured to transmit a reply message to the request message based on a decision by the decider, wherein, in a case where it is determined that the digital content corresponding to the requested content identifier does not include the requested data range, the decider decides an alternative content identifier different from the requested content identifier and an alternative data range indicating a segment of a digital content having the alternative content identifier, and the segment corresponds to the part of the requested digital content, and wherein at least one of the receiver, the determiner, the decider, and the transmitter is implemented using a processor.
