Abstract
To provide a packet transmitter apparatus which can transmit contents protected by a content protection technique such as DTCP or the like, using packets such as IP packets which have become widespread. The packet transmitter apparatus includes a transmitting condition setting management unit () which extracts at least one of charge information, playback control information and copy control information of AV data from the inputted non-AV data or AV data and generates, based on the extracted information, encryption mode information indicating an encryption mode which becomes a condition at the time of transmitting the AV data; an encrypted data generation unit () which generates encrypted data by encrypting, based on the transmitting condition, the inputted AV data and adding encryption information headers based on the encryption mode information to the encrypted AV data; and a packet generation unit () which generates packets by adding packet headers to the generated encrypted data. The transmitting condition is to be determined as a combination of input terminal information, data format information and attribute information.
