Cable and connection device
It is made possible to consume current without adversely affecting the others. 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.
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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
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.
