Abstract

A MOST(Media Oriented System Transport) tuner apparatus and its control method are provided to reduce a unit cost of a product by reducing the number of components, and allow a plurality of devices to share resources through MOST communication. It is checked whether DMB(Digital Multimedia Broadcasting), an analog TV broadcast or a radio broadcast is selected. When the DMB broadcast is selected, a DMB receiving unit is driven, when the analog TV broadcast is selected, an analog TV receiving unit is driven, and when the radio broadcast is selected, a radio receiving unit is driven, to receive a corresponding broadcast(211,213,215,217,227,239). When the DMB receiving unit is driven, audio data with respect to the DMB broadcast is processed, and the processed audio data and image data are converted into VDM data(219,223). When the analog TV receiving unit is driven, an analog image signal and an analog audio signal with respect to the analog TV broadcast are converted into digital video data, and audio data is converted into VDM data(229,235). When the radio receiving unit is driven, an audio signal with respect to the radio broadcast is converted into audio data and then converted into VDM data(241,245). The converted VDM data is transmitted to a MOST network according to a MOST protocol(225,237).
