KR970023328A - Voice Receiving Circuit and Method of VCR with FM Receiver - Google Patents

Abstract

The present invention has an FM receiver built in the VCR to easily receive the voice signal of the FM channel according to the user's intention, so that the FM channel in the language region of the TV broadcast or the region where the voice reception is not properly performed The present invention relates to a voice reception circuit and a method of a VCR with an FM receiver that enables recording and editing of a VCR according to a user's intention by using a voice signal of the user. FM receiving means for detecting and outputting an FM audio signal by means of one of the plurality of input signals and the FM receiving signal outputted from the FM receiving means by means of an input control signal of the main control means, and applying them to the audio processing means of the VCR. And audio input selecting means for outputting FM tuning data to the FM receiving means to tune the FM channel. Main control means for receiving the voice detection signal output from the FM receiving means, searching and storing the FM channel, and outputting an input control signal to the voice input selecting means to selectively output one of a plurality of input signals; Key input means for controlling the operation of the outside and the voice processing means for outputting the voice signal output from the voice input selection means as a voice signal in the recording or general broadcast mode for editing through a VCR, TV And a first step of checking whether an FM selection key is input when a synchronization signal is detected during a broadcast signal search operation of a channel selected by the VCR tuner; and the current TV and VCR tuner if the FM selection key is not input as a result of the check of the first step. The second step of storing the selected channel as a voice receiving channel, and if the FM selection key is entered as the check result of the first step A third step of selectively searching for channels and storing them as voice receiving channels; and automatically receiving voice signals of the voice receiving channels stored in the second and third steps and outputting them to the voice output lines of TV and VCR channels. In step 4 and during receiving the RF signal in the normal mode through the TV channel, it is checked whether the FM selection key is input, and according to the FM selection key input, the audio signal of the currently selected TV channel is received and output as it is or in the FM reception mode. A fifth step of switching, and a sixth step of selectively searching for an FM channel and receiving an audio signal of the corresponding FM channel and outputting it to a voice output line while checking whether a voice signal is detected after switching to the FM reception mode. Is in.

Claims (3)

FM reception means for detecting and outputting an FM audio signal by FM tuning data from a reception signal received through an antenna, and one of the FM reception signal outputted from the FM reception means and a plurality of input signals to the input control signal of the main control means. Selects and inputs to the audio processing means of the VCR, and outputs the FM tuning data to the FM receiving means to tune the FM channel, and receives the audio detection signal output from the FM receiving means. A main control means for searching for and storing an output control signal to the voice input selection means to selectively output one of a plurality of input signals, a key input means for externally controlling the operation of the main control means, and the voice Recording or general broadcasting so that audio signal output from input selection means can be edited through VCR. The VCR with a built-in FM receiver characterized in that it consists of a sound processing means for outputting a sound signal of the de audio receiving circuit. A first step of checking whether an FM selection key is input when a synchronization signal is detected during a broadcast signal search operation of a channel selected by a TV and a VCR tuner; and if the FM selection key is not input as a result of the check of the first step, the current TV and VCR A second step of storing the channel selected by the tuner as a voice reception channel; a third step of selectively searching for and storing the FM channel as a voice reception channel when the FM selection key of the first step is input; and the second step And a fourth step of automatically receiving the voice signal of the voice reception channel stored in the step and the third step and outputting the voice signal to the voice output line of the TV and the VCR channel. The fifth step of checking whether the FM selection key is input while receiving the RF signal in the normal mode through the TV channel and receiving or outputting the audio signal of the currently selected TV channel according to the FM selection key input or switching to the FM reception mode. And a sixth step of selectively searching for an FM channel, receiving an audio signal of the corresponding FM channel, and outputting it to a voice output line while checking whether a voice signal is detected after switching to the FM reception mode. Voice reception method of VCR with FM receiver. ※ Note: The disclosure is based on the initial application.
