ABSTRACT:
A radio VOD (Video-On-Demand) system is disclosed. A server provides a video file and an audio file, and a server manager manages the server so as to transmit a video file and an audio file at the user's request. An exchange converts the video file and the audio file provided from the server through a network to the corresponding video and audio signals. A mobile terminal receives the video and audio signals from the exchange through separate channels, and reads only the user requested data from the received video and audio signals. The mobile terminal comprises first and second tuners for separately receiving the video signal and the audio signal, respectively; a signal processor for detecting a video signal and an audio signal, selected by the user, from the video and audio signals received through the first and second tuners; first and second decoders for decoding the video and audio signals detected by the signal processor, respectively; a video display for outputting the decoded video signal; and an audio output device for outputting the decoded audio signal.
