Information Processing Apparatus, Information Processing Method, and Computer Program
First Claim
1. An information processing apparatus for receiving broadcast data and outputting the received data to a client connected to a network, the information processing apparatus comprising:
- a broadcast receiving unit that receives broadcast data;
an encryption processor that performs encryption processing on the broadcast data received by the broadcast receiving unit;
a data accumulation unit that accumulates encrypted data generated by the encryption processor;
a data transmission unit that generates a communication packet in which encrypted data accumulated in the data accumulation unit is stored and outputs the generated communication packet; and
a transmission data controller that monitors a retained state of the encrypted data in the data accumulation unit and removes, if a state different from a predetermined allowable retained state is detected, at least part of the encrypted data accumulated in the data accumulation unit from transmission data.
