BROADCAST RECEIVING APPARATUS AND BROADCAST RECEIVING METHOD

摘要

PURPOSE: A broadcast receiving device and method are provided to receive a plurality of channels at the same time by using one tuner. CONSTITUTION: An IF(Intermediate Frequency) conversion unit(220) converts RF(Radio Frequency) band broadcast signals of a plurality of channels, which is received from an RF receiving unit(210), into a signal of an IF band. A plurality of signal processing units(230) processes and outputs each IF signal. A noise generation unit(240) generates a noise signal corresponding to the IF signal. When one or more channels are changed corresponding to input of a user, a control unit(260) controls to output a noise signal instead of the IF signal.
