1. A device for transferring network data, the device comprising: a data processing module configured to convert a data signal in a transition minimized differential signaling (TMDS) signal output via a digital video interface of a graphics card to network data for being transferred via a network; and a network transmitter for receiving the network data and transferring the network data to an external device via the network; wherein the data signal is generated by encoding texture data generated by a graphics processing unit of the graphics card by a digital video sender of the graphics card; wherein the texture data is generated by binding a pointer to general computing data stored in a device memory of the graphics card to a texture stored in the device memory by the graphics processing unit; and wherein the general computing data is generated by general computation executed by the graphics processing unit.
