Abstract:
1. A transmitting apparatus connected to a communication medium for determining whether to transmit a predetermined content to a reception apparatus, said transmitting apparatus comprising: generation means for generating authentication data; measurement command transmission means for transmitting a command via the communication medium to the reception apparatus for authentication of the reception apparatus, the transmitted command including at least a portion of the authentication data generated by the generation means; measurement response reception means for receiving a response to the transmitted command, the response received from the reception apparatus and including response data having a number of authentication retry times; measuring means for measuring a round trip response time to the command; authentication means for authenticating the reception apparatus in accordance with the round trip response time and the response data, the reception apparatus authenticated upon determination that the round trip response time minus a generation time for the reception apparatus to generate the response to the command is below a predetermined interval; control command transmission means for transmitting, upon authentication of the reception apparatus by the authentication means, a confirmation command request requesting the reception apparatus to transmit confirmation data related to the authentication data contained in the command and the response data contained in the response to the command; and determination means for determining whether to transmit the predetermined content to the reception apparatus based on the confirmation data from the reception apparatus, wherein transmission of the command for authentication of the reception apparatus according to the round trip response time minus the generation time to generate the response command is automatically repeated without manual input upon determination that the reception apparatus is unauthenticated and the command has been transmitted less than the number of authentication retry times.
