Patent ID: 8874895

Claim:
A data transmitting apparatus comprising: a first encryption unit that encrypts image information of input content with a first encryption scheme; a wireless communication unit that transmits, by wireless communication, the image information encrypted by the first encryption unit; a second encryption unit that encrypts image information of input content with a second encryption scheme; a wire communication unit that transmits, by wire communication, the image information encrypted by the second encryption unit; a device information obtaining unit that obtains device information of a connected device; an authentication unit that authenticates validity of the data receiving apparatus, based on the device information obtained by the device information obtaining unit; and a control unit that performs control as to obtain the device information through the wireless communication unit, and transmit the image information encrypted by the first encryption unit from the wireless communication unit when the validity of the data receiving apparatus is authenticated by the authentication unit, and as to obtain the device information through the wire communication unit, and transmit the image information encrypted by the second encryption unit from the wire communication unit when the validity of the data receiving apparatus is authenticated by the authentication unit, wherein transmission of the image information via wireless communication is conditioned on authentication of the receiving device using wire-input security information to conduct a High-bandwidth Digital Content Protection system (HDCP) revocation process, and wherein the control unit performs control as to transmit the image information from the wireless communication unit or the wire communication unit, such that when the image information is transmitted from the wireless communication unit the image information is transmitted as encrypted according to the first encryption scheme, and when the image information is transmitted from the wire communication unit the image information is transmitted as encrypted according to the second encryption scheme.
