Description

휴대폰 겸용 DMB 수신기{DMB receiver which also serves as a mobile phone}DMB receiver which also serves as a mobile phone}

본 발명은 DMB 수신기에 관한 것으로, 특히 DMB 핸드폰 겸용 수신기에서 오디오 방송을 핸드폰을 통해 통화 상대자에게 전달하는 방법에 관한 것이다.The present invention relates to a DMB receiver, and more particularly, to a method of delivering an audio broadcast to a call partner through a cellular phone in a DMB dual-purpose receiver.

방송의 디지털화는 종래 아날로그 라디오 방송에도 영향을 주어 디지털 라디오 방송의 도래를 앞당겼다. 또한 종래 음성 라디오 서비스뿐만 아니라, 데이터 전송과 멀티미디어 서비스를 포괄하는 디지털 멀티미디어 방송(Digital Multimedia Broadcasting : DMB)이 가능해졌다.Digitization of broadcasts has also affected conventional analog radio broadcasts, speeding up the advent of digital radio broadcasts. In addition to the conventional voice radio service, digital multimedia broadcasting (DMB), which includes data transmission and multimedia services, has become possible.

상기 DMB 수신기의 경우, 그 다양한 응용 형태가 제시되고 있는데, 그 중 하나가 바로 상기 DMB 수신도 가능하고 휴대폰으로도 사용할 수 있는 휴대폰 겸용 DMB 수신기이다.In the case of the DMB receiver, various application forms have been proposed, and one of them is a mobile phone combined DMB receiver that can receive the DMB and can be used as a mobile phone.

이처럼 DMB 수신기가 휴대폰과 결합될 경우에 사용자는 휴대폰으로 통화를 하면서 수신되는 방송의 오디오를 상대방에게 들려주고 싶어할 수 있다.As such, when the DMB receiver is combined with the mobile phone, the user may want to hear the audio of the broadcast received while talking on the mobile phone.

이때, 수신기의 스피커를 통해 나오는 음악을 핸드폰의 마이크를 통해 상대방에게 전달할 경우 사용자 주변의 잡음이 많이 섞여 전화를 받는 상대방에게 좋은 음질의 음악을 들려줄 수 없는 문제점이 있다.At this time, when the music coming out of the speaker of the receiver to the other party through the microphone of the mobile phone is mixed with a lot of noise there is a problem that can not hear the good quality music to the other party receiving the call.

따라서, 본 발명의 목적은 이와 같은 종래 기술의 문제점을 해결하기 위해 안출한 것으로서, 휴대폰 겸용 DMB 수신기로 전화 통화시 상대방에게 멀티미디어 방송 중 오디오 방송을 음질저하 없이 전송하는 방법을 제시하는데 있다.Accordingly, an object of the present invention is to solve the problems of the prior art, to provide a method for transmitting an audio broadcast during a multimedia broadcast to the other party without a deterioration of sound when a telephone call with a mobile phone combined DMB receiver.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 휴대폰 겸용 DMB 수신기는 전송된 디지털 멀티미디어 방송을 수신하는 DMB 수신부와, 상기 DMB 수신부에서 출력되는 오디오 신호를 내부 인터페이스를 통해 입력 받아 보이스 코딩하여 통신망을 통해 전송하는 휴대폰 기능부를 포함하여 구성됨을 특징으로 한다.DMB receiver according to the present invention for achieving the above object is a DMB receiving unit for receiving the transmitted digital multimedia broadcasting, and the audio signal output from the DMB receiving unit via the internal interface and voice-coded through a communication network Characterized in that it comprises a mobile phone function to transmit.

이하 발명의 바람직한 실시예에 따른 구성 및 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, a configuration and an operation according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 따른 휴대폰 겸용 DMB 수신기의 구조를 나타낸 도면이다.1 is a view showing the structure of a mobile phone DMB receiver according to the present invention.

도 1과 같이, 휴대폰 겸용 DMB 수신기는, 전송된 멀티미디어 방송을 수신하여 디스플레이 장치(1) 및 스피커(2)를 통해 내보내는 DMB 수신 기능을 갖는 DMB 수신부(3)와, 상기 디스플레이 장치(1) 및 스피커(2)를 공유하며, 휴대폰 기능을 갖는 휴대폰 기능부(4) 및 상기 휴대폰에 사용자의 음성을 입력하기 위한 마이크(5)로 구성된다. 상기 DMB 수신부(3) 및 휴대폰 기능부(4)의 상세 구성은 일반적인 기술 사상이므로 생략한다.As shown in FIG. 1, the DMB receiver combined with a mobile phone may include a DMB receiver 3 having a DMB reception function for receiving a transmitted multimedia broadcast and outputting the same through the display apparatus 1 and the speaker 2, the display apparatus 1, and The speaker 2 is shared and comprises a mobile phone function unit 4 having a mobile phone function and a microphone 5 for inputting a user's voice into the mobile phone. Detailed configurations of the DMB receiver 3 and the cellular phone functional unit 4 are omitted because they are general technical concepts.

이와 같은 구성을 갖는 휴대폰 겸용 DMB 수신기는 멀티미디어 방송을 수신하여 비디오는 상기 디스플레이 장치(1)로, 오디오는 스피커(2)로 출력하게 되는데, 상기 오디오 신호가 휴대폰 기능부(4)의 입력 신호로도 들어갈 수 있도록 구현되었다.The DMB receiver having such a configuration receives a multimedia broadcast and outputs video to the display device 1 and audio to the speaker 2. The audio signal is an input signal of the cellular phone function unit 4. It was also implemented to get in.

즉, 사용자가 상기 휴대폰 겸용 DMB 수신기에 별도로 부착된 오디오 신호 전환 버튼을 누르게 되면, 상기 DMB 수신부(3)에서 스피커(2)로 보내주는 오디오 신호를 바로 휴대폰 기능부(4)로 입력되게 하여, 상기 휴대폰 기능부(4)가 상기 오디오 신호인 아날로그 신호를 입력받아 PCM과 같은 디지털 신호 변환 과정인 보이스 코딩(voice coding)함으로써 통신망을 통해 통화 상대방에게 전송하게 되는 것이다. 상기 전송 과정은 일반적인 휴대폰의 전송 과정과 같다.That is, when a user presses an audio signal switching button separately attached to the mobile phone combined DMB receiver, an audio signal transmitted from the DMB receiver 3 to the speaker 2 is directly input to the mobile phone function unit 4, The cellular phone function unit 4 receives the analog signal, which is the audio signal, and transmits it to a call counterpart through a communication network by voice coding, which is a digital signal conversion process such as PCM. The transmission process is the same as the transmission process of a general mobile phone.

따라서, 사용자가 이와 같은 휴대폰 겸용 DMB 수신기를 이용하여 휴대폰 통화를 하면서 멀티미디어 방송을 감상하는 도중에, DMB 수신부(3)를 통해 수신된 오디오 방송 내용을 내부 인터페이스를 통해 휴대폰 기능부(4)로 전송하고, 상기 휴대폰 기능부(4)는 통화 상대자에게 외부 소음이 추가되지 않은 상태로 전달하게 된다. Therefore, while the user is listening to the multimedia broadcast while making a mobile phone call using such a mobile phone DMB receiver, the audio broadcast contents received through the DMB receiver 3 are transmitted to the mobile phone function unit 4 through an internal interface. , The mobile phone function unit 4 is delivered to the call party in the state that the external noise is not added.

이때, 사용자의 필요에 따라 통화 상대자에게 오디오 방송 뿐 아니라, 오디오 방송 중에 사용자의 음성을 섞어서(mixing) 동시에 전달할 수도 있다.At this time, according to the needs of the user, not only the audio broadcast but also the voice of the user may be mixed and delivered simultaneously during the audio broadcast.

이상의 설명에서와 같이 본 발명에 따른 휴대폰 겸용 DMB 수신기는 다음과 같은 효과가 있다.As described above, the combined mobile phone DMB receiver according to the present invention has the following effects.

첫째, 전화를 받는 상대방은 DMB 수신기가 없어도 휴대폰을 통해 DMB 오디오 방송을 듣게 되는 효과가 있다.First, the other party receiving the call has an effect of listening to DMB audio broadcasting through a mobile phone even without a DMB receiver.

둘째, 전화를 받는 상대방에게 DMB 오디오 방송을 음질저하 없이 전달하게 되어 사용자의 만족도를 높이는 효과가 있다.Secondly, DMB audio broadcasting is delivered to the other party receiving the call without degrading the sound quality, thereby enhancing the user's satisfaction.

이상 설명한 내용을 통해 당업자라면 본 발명의 기술 사상을 일탈하지 아니하는 범위에서 다양한 변경 및 수정이 가능함을 알 수 있을 것이다.Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

따라서, 본 발명의 기술적 범위는 실시예에 기재된 내용으로 한정하는 것이 아니라 특허 청구 범위에 의해서 정해져야 한다.Therefore, the technical scope of the present invention should not be limited to the contents described in the examples, but should be defined by the claims.
