- 멀티채널엑세스 방식을 사용하는 무선 마이크의 무선 전송방법에 있어서,무선 마이크의 전원을 온시키면 채널탐색모드로 전환하여 현재 사용되지 않는 빈 채널을 자동 탐색하는 단계;상기 채널 탐색결과 빈 채널이 검출되면 무선 마이크를 채널탐색모드에서 송신모드로 절환한 후 빈 채널코드를 기 설정된 마스터 채널을 통해 발신하는 단계;상기 마스터 채널을 통해 발신된 빈 채널코드를 수신장치에서 수신한 후 분석하는 단계; 및상기 코드분석결과 무선 마이크에서 탐색한 빈 채널을 검출한 후 해당 수신장치를 무선 마이크의 빈 채널에 동조하여 음성신호를 수신하는 단계를 포함하여 이루어진 것을 특징으로 하는 무선 마이크의 채널확장방법.
- 제 1 항에 있어서, 상기 빈 채널탐색 단계는 각 채널별로 반송파를 검출하여 반송파가 검출되지 않으면 현재 사용되고있지 않은 빈 채널로 판단함을 특징으로 하는 무선 마이크의 채널확장방법.
- 제 1 항에서 있어서, 상기 수신장치가 수신대기상태에 있을 때는 마스터 채널로 수신대기함을 특징으로 하는 무선 마이크의 채널확장방법.
- 제 3 항에 있어서, 상기 마스터 채널은 무선 마이크와 수신장치를 제 1 채널로 설정함을 특징으로 하는 무선 마이크의 채널확장방법.
- 제 1 항에 있어서, 상기 무선 마이크는 노래방에서 사용 가능한 무선 헤드셋임을 특징으로 하는 무선 마이크의 채널확장방법.
