  • Publication number: 20090144805
    Abstract: According to one embodiment, when a power source of an information transfer apparatus is turned off, information indicating termination of authentication with an AV apparatus externally connected is stored and whether or not the AV apparatus is set in a disconnected state in a power-off period is detected. Then, in a case where it is detected that the AV apparatus is not set in the disconnected state in the power-off period when the power source is turned on, a digital signal is transferred with respect to the AV apparatus based on the stored information indicating termination of authentication.
