VEHICLE-MOUNTED DEVICE AND DEVICE AUTHENTICATION METHOD

摘要

A vehicle-mounted device includes a first authentication unit for performing first authentication processing in which, when a first device is connected to an output unit, the vehicle-mounted device is authenticated as a source device and the first device is authenticated as a sink device; a second authentication unit for performing second authentication processing in which, when a second device is connected to the input unit while a digital content is being output to the first device from the output unit, the vehicle-mounted device is authenticated as the sink device and the second device is authenticated as the source device; a determination unit; and a third authentication unit for performing third authentication processing in which the vehicle-mounted device is authenticated as a repeater device when a condition for providing the digital content from the second device to the first device is determined to be satisfied by the determination unit.

1. A vehicle-mounted device including an input unit connectable to a device compatible with a predetermined interface standard and inputting a digital content from the device and an output unit connectable to a device compatible with the predetermined interface standard and outputting a digital content to the device, the vehicle-mounted device comprising:
a first authentication unit for performing first authentication processing in which, when a first device compatible with the predetermined interface standard is connected to the output unit, the vehicle-mounted device and the first device authenticate the vehicle-mounted device as a source device at a transmission side of the digital content and authenticate the first device as a sink device at a reception side of the digital content; a second authentication unit for performing second authentication processing in which, when a second device compatible with the predetermined interface standard is connected to the input unit while the digital content is being output to the first device authenticated as the sink device from the output unit, the vehicle-mounted device and the second device authenticate the vehicle-mounted device as the sink device and authenticate the second device as the source device; a third authentication unit for performing third authentication processing in which the vehicle-mounted device, the second device, and the first device authenticate the vehicle-mounted device as a repeater device for relaying a digital content between the second device authenticated as the source device and the first device authenticated as the sink device; a determination unit for determining whether a condition for providing the digital content from the second device authenticated as the source device to the first device authenticated as the sink device is satisfied or not; and a content output control unit configured such that, when the determination unit determines that the condition for providing the digital content from the second device to the first device is satisfied, the digital content from the second device which is input from the input unit is relayed and output to the first device via the output unit after the third authentication unit finishes the third authentication processing.
