Title: Method for maintaining audition broadcasting at seek/scan function
Inventor: KWON SANG HYUK
IPC: H03J7/00
Filed: 1998-10-02
Abstract: PURPOSE: A method for maintaining an audition broadcasting at a SEEK/SCAN function is provided to continue to audition a broadcasting without a mute by adding a channel for scanning a valid channel. CONSTITUTION: In a method for maintaining an audition broadcasting at a SEEK/SCANfunction, if a user inputs a SEEK or SCAN key(S11), a control part varies a frequency to transfer the varied frequency data to a phase locked loop(S12). After analyzing the changed frequency data, a voltage is adjusted into regular voltage, and the adjusted voltage is outputted to a low pass filter(S13). The low pass filter changes the transferred voltage into a system voltage necessary for a multiple tuner part, and outputs the changed voltage to a second channel of the tuner part(S14). The tuner part transfers the changed frequency and a frequency received from an antenna to the phase locked loop by a reference oscillator(S15), and the phase locked loop transfers data, indicating whether a valid channel is sensed, to a control part. If a valid channel exists, the control part converts an analog voltage value of the phase locked loop into a digital voltage value(S17). If a valid channel does not exist, return to the step(S12)(S16). A digital voltage value of an audition frequency of the valid channel is converted into an analog voltage value, and then it is adjusted into an offset voltage(S18). The resultant voltage value is transferred to a first channel(S19). A broadcasting of the first channel is replaced with a broadcasting of the valid channel(S20), and the broadcasting of the valid channel is outputted through a speaker(S21).
