1. A digital radio system comprising:
an analog radio transceiver configured to, while changing a used frequency band at any time, communicate with another analog radio transceiver through the used frequency band; and
a mobile terminal configured to allow connection of the analog radio transceiver, and then decode a signal received through the analog radio transceiver and reconstruct and reproduce at least one of audio data, image data, and metadata, or encode at least one audio data, image data, and metadata generated by a user and wirelessly transmit the encoded data through the analog radio transceiver,
wherein the mobile terminal comprises:
an external device connector configured to support connection and communication of the analog radio transceiver;
a data input/output unit comprising at least one of a touchscreen, a speaker, a microphone, and a camera; and
a radio transceiver application configured to decode an output signal of the analog radio transceiver, reconstruct the output signal into at least one of audio data, image data, and metadata, and then reproduce the reconstructed data through the data input/output unit, or encode at least one of audio data, image data, and metadata obtained through the data input/output unit and then transmit the encoded data to the analog radio transceiver through the external device connector,
wherein the radio transceiver application comprises:
an input buffer configured to sequentially store output signals of the analog radio transceiver and then sequentially output the stored signals in units of frames;
a decoder configured to decode an output signal of the input buffer;
an encoder configured to encode at least one of audio data, image data, and metadata obtained through the data input/output unit;
an output buffer configured to sequentially store output signals of the encoder and then sequentially output the stored signals to the external device connector in units of frames; and
a controller configured to configure and provide a graphical user interface (GUI), and control an overall application operation according to a user control value input through the GUI.
