Abstract
There is provided a processing apparatus which increments and thereby restores a lendable number upon receiving a content returned from a portable device, and which confirms the return of the content and increments the lendable number even when the portable device does not have or deletes the content borrowed from the processing apparatus before returning the content.
Claims4
An information processing apparatus, comprising:
- transmitting means for transmitting content and necessary information for the content to a recording apparatus for storage, said necessary information including a key used to decipher the content;
- storing means for storing an initial allowable number of transmissions corresponding to the content;
- managing means for managing the transmission of the content based on the initial allowable number of transmissions, and, decrementing the initial allowable number upon transmission;
- wherein the managing means manages the decrementing of the initial allowable number of transmissions when the content and the necessary information are transmitted to the recording apparatus, and, after confirming that the necessary information has been deleted by the recording apparatus, increments an allowable number of transmissions.
