Abstract: Reception buffer, transmission buffer, transmission-reception buffer, reception filter and transmission filter are provided. The reception filter determines where a received packet should be stored based on the contents of the received packet. Specifically, in executing a READ command, a response packet, which is returned in response to a data transmission packet, is detected by the reception filter. Received packets of the other types are stored on the reception buffer. In executing a WRITE command, a data request packet is transmitted from the transmission buffer. A data reception packet responding to the data request packet is stored by the reception filter on the transmission-reception buffer. Received packets of the other types are stored on the reception buffer. The capacity of the transmission-reception buffer is twice as large as the size of a maximum transferable packet. Thus, overhead can be reduced and yet data can be transferred at higher speeds.

Abstract: An authentication processing apparatus includes an authentication unit, having a circuit that performs authentication phases included in processing for authenticating an external device. A command holding unit holds a first command that indicates whether or not each of the authentication phases is performed by the authentication unit. An authentication controller causes the authentication unit to perform an authentication phase that is indicated, by the first command, to be performed by the authentication unit. A CPU performs software processing of an authentication phase that is indicated, by the first command, not to be performed by the authentication unit.

Abstract: An audio-video output apparatus of the present invention outputs at least one of audio data and video data to a receiving apparatus using High-Definition Multimedia Interface (HDMI) communications. The audio-video output apparatus includes a list holding unit, an authenticating unit, a list acquiring unit, an updating unit, and an apparatus verifying unit. The list holding unit holds an unauthorized apparatus list which shows information about unauthorized apparatuses. The authenticating unit performs first apparatus authentication to verify whether or not the receiving apparatus is an authorized apparatus using the unauthorized apparatus list held by the list holding unit, and performs second apparatus authentication at regular intervals to verify the receiving apparatus is an authorized apparatus. The list acquiring unit acquires another unauthorized apparatus list. When the unauthorized apparatus list acquired by the list acquiring unit is newer than the unauthorized apparatus list held by the list holding unit, the updating unit updates the unauthorized apparatus list held by the list holding unit to the unauthorized apparatus list acquired by the list acquiring unit. When the unauthorized apparatus list is updated by the updating unit, the apparatus verifying unit verifies whether or not the receiving apparatus is an authorized apparatus using the updated unauthorized apparatus list, the verification being performed in parallel with the second apparatus authentication performed by the authenticating unit.
