Method for improving data transmission speed and electronic device implementing the same
A method for improving a data transmission speed and an electronic device implementing the same are provided. The electronic device includes a USB connection unit configured to be connectable to an external electronic device and including designated data reception channels and data transmission channels, a switch unit configured to switch an electrical connection between the data reception channels and data transmission channels, and a control unit configured to confirm device attribute information of the external electronic device that is connected through the USB connection unit and to control the switch unit to switch the electrical connection so that at least one data reception channel functions as a data transmission channel if the connected external electronic device is a display device.
1. An electronic device comprising:
a USB connection unit configured to be connectable to an external electronic device and including a data reception channel and a data transmission channel;
a switch unit configured to switch an electrical connection between the data reception channel and data transmission channel; and
a control unit configured to:
recognize a connection with the external electronic device via the USB connection unit,
detect whether the external electronic device is a display device based on device attribute information of the external electronic device, and
control the switch unit to switch the electrical connection so that the data reception channel functions as a data transmission channel if the external electronic device is the display device.
2. The electronic device of claim 1 , wherein the control unit transmits a confirmation request signal for detecting whether the external electronic device is the display device, receives a response signal that is transmitted from the external electronic device in response to the confirmation request signal, and identifies that the external electronic device is the display device on the basis of the device attribute information included in the response signal.
3. The electronic device of claim 2 , wherein the device attribute information includes an ID value predefined based on the external electronic device, and a specific numerical value corresponding to the display device to detect whether the external electronic device is the display device.
4. The electronic device of claim 1 , wherein the control unit transmits a switching request for switching an electrical connection so that a data transmission channel of the USB connection unit that is provided in the display device functions as a data reception channel of the USB connection unit.
5. A method for improving a transmission speed of an electronic device, the method comprising:
recognizing, by the electronic device, a connection with an external electronic device via a USB connection unit including a data reception channel and a data transmission channel;
detecting, by the electronic device, whether the external electronic device is a display device based on device attribute information of the external electronic device; and
if the external electronic device is the display device, switching an electrical connection so that the data reception channel functions as a data transmission channel.
6. The method of claim 5 , wherein detecting whether the external electronic device is a display device based on the device attribute information of the external electronic device comprises:
transmitting a confirmation request signal for detecting whether the external electronic device is the display device;
receiving a response signal from the external electronic device in response to the confirmation request signal; and
identifying that the external electronic device is the display device on the basis of the device attribute information included in the response signal.
7. The method of claim 6 , wherein the device attribute information includes an ID value predefined based on the external electronic device, and a specific numerical value corresponding to the display device to detect whether the external electronic device is the display device.
8. The method of claim 5 , further comprising transmitting a switching request for switching an electrical connection so that a data transmission channel of the USB connection unit that is provided in the display device functions as a data reception channel of the USB connection unit.
