Control apparatus, control method, cable, electronic apparatus, and communication apparatus

A cable connected to an electronic apparatus to which a bus power cable capable of supplying a power source by bus power can be connected, the cable comprising:

• a reception unit configured
• to receive a modulation signal obtained by frequency-converting a baseband signal of a baseband into a signal of a predetermined frequency band higher than the baseband, and
• to frequency-convert it into the baseband signal;
• a power detection unit configured to detect power of the modulation signal received by the reception unit;
• and
• a controller configured to control the electronic apparatus receiving the baseband signal to start initialization processing for causing the electronic apparatus to be in a state of being capable of establishing connection or to turn on or off a power source based on detection results of the power of the modulation signal in the power detection unit.

An electronic apparatus to which a bus power cable capable of supplying a power source by bus power can be connected, the electronic apparatus comprising:

• a reception unit configured
• to receive a modulation signal obtained by frequency-converting a baseband signal of a baseband into a signal of a predetermined frequency band higher than the baseband, and
• to frequency-convert it into the baseband signal;
• a power detection unit configured to detect power of the modulation signal received by the reception unit;
• and
• a controller configured to control the electronic apparatus receiving the baseband signal to start initialization processing for causing the electronic apparatus to be in a state of being capable of establishing connection or to turn on or off a power source based on detection results of the power of the modulation signal in the power detection unit.

A communication apparatus, comprising:

• a transmission unit configured to transmit a modulation signal obtained by frequency-converting a baseband signal of a baseband into a signal of a predetermined frequency band higher than the baseband to an apparatus configured
• to receive the modulation signal,
• to detect power of the modulation signal, and
• to control an electronic apparatus receiving the baseband signal to start initialization processing for causing the electronic apparatus to be in a state of being capable of establishing connection or to turn on or off a power source based on detection results of the power of the modulation signal;
• and
• a controller configured to control on and off of transmission of the modulation signal.

A control method, comprising:

• controlling on and off of transmission of a modulation signal obtained by frequency-converting a baseband signal of a baseband into a signal of a predetermined frequency band higher than the baseband to an apparatus configured to control an electronic apparatus, the electronic apparatus being configured
• to receive the modulation signal,
• to detect power of the modulation signal, and
• to control the electronic apparatus receiving the baseband signal to start initialization processing for causing the electronic apparatus to be in a state of being capable of establishing connection or to turn on or off a power source based on detection results of the power of the modulation signal.
