Abstract
There is provided a conversion cable including: a connector to be connected to an electronic device that outputs a digital voice signal; an IC having a function of converting a digital voice signal supplied through the connector into an analog voice signal; and an output unit for an analog voice signal output from the IC, in which the IC holds an encryption key for permitting the electronic device to output a digital voice signal that requires copyright protection.
Claims11
A conversion cable comprising:
- a connector to be connected to an electronic device that outputs a digital voice signal;
- an IC having a function of converting a digital voice signal supplied through the connector into an analog voice signal;
- and
- an output unit for an analog voice signal output from the IC,
- wherein the IC holds an encryption key for permitting the electronic device to output a digital voice signal that requires copyright protection.
An electronic device, wherein an application for outputting a digital voice signal that requires content protection is installed, the conversion cable is authenticated by using the application with a key held by an IC of a connected conversion cable, and only in a case where the conversion cable is authenticated, a digital voice signal is output to the conversion cable.
