A cable is connected between a first device and a second device. A power line that supplies a current from the first device to the second device, and a current consumption unit that receives supply of a current from the first device through the power line, are included. A detection unit that detects that the second device is in the operating state, and a control unit that cancels a stop state of current consumption of the current consumption unit in response to the detection information, are further included. ## Claims ### Claim 1 A cable connected between a first device and a second device, the cable comprising: a power line configured to supply a current from the first device to the second device; a current consumption unit configured to: receive the supply of the current from the first device through the power line, and adjust a signal quality interposed in a data line on a side of the first device; a detection unit configured to detect that the second device is in a first operating state; and a control unit configured to cancel a stop state of current consumption of the current consumption unit based on the detection that the second device is in the first operating state. ### Claim 2 (depends on 1) The cable according to claim 1, wherein the detection unit is further configured to detect that the second device is in the first operating state when a specific voltage is applied to a data line on a side of the second device. ### Claim 3 (depends on 1) The cable according to claim 1, wherein the detection unit is further configured to send detection information, that indicates the detection of the second device in the first operating state, to the control unit through a specific line. ### Claim 4 (depends on 1) The cable according to claim 1, wherein the control unit is further configured to control the current consumption unit to operate in a second operating state based on the detection that the second device is in the first operating state. ### Claim 5 (depends on 1) The cable according to claim 1, further comprising a power source unit configured to supply the current to the current consumption unit wherein the control unit is further configured to control the power source unit to operate in a second operating state based on the detection that the second device is in the first operating state. ### Claim 6 (depends on 1) The cable according to claim 1, wherein the first device is a High Definition Multimedia Interface (HDMI) transmitter, and the second device is an HDMI receiver. ### Claim 7 A connection device that connects a first device and a second device, the connection device comprising: a power line configured to supply a current from the first device to the second device; a current consumption unit configured to: receive supply of the current from the first device through the power line, and adjust a signal quality interposed in a data line; a detection unit configured to detect that the second device is in an operating state; and a control unit configured to cancel a stop state of current consumption of the current consumption unit based on the detection that the second device is in the operating state.
