Adjustable video conversion method

A method for adjustable video conversion is provided. A mobile communication device is used to output a control signal to a control interface, the control interface converts the signal into a processing signal and outputs the signal to a converter, to conduct a link between the first interface input port and the network interface output port, and selects the corresponding first interface to receive the first signal of the source terminal and the corresponding network interface to output the second signal, The converter performs conversion operation according to the selected interface specification to process the signal conversion between the first signal and the second signal, and finally transmits the second signal to a remote station for playing through a network through the network interface output port. Thereby, the invention can be directly operate remotely by a smart phone or a tablet computer through a USB connection or a Bluetooth mode, thereby solving the inconvenience of useroperation setting, or av
