이하, 첨부한 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 기술하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도면은 본 발명의 일실시예에 따른 다운로드가 가능한 디지털오디오기기를 나타내는 구성도이다. 도면에 나타낸 디지털오디오기기(10)는 개인휴대통신기기와 연결되는데 최근에 보편화된 피씨에스(PERSONAL COMMUNICATION SYSTEM : 이하 PCS라함)와 RS232C로 무선연결되도록 구성되어 있다. 또한, 디지털오디오기기(10)는 PC와도 RS232C로 무선연결가능하다. 본 발명의 실시예에서는 PCS(20)를 일예로 설명한다. 여기서, PCS(20)는 PC통신과 인터넷상의 서비스업체와 협의하여 사용자의 요청에 따라 디지털오디오데이터를 수신하여 RS232C통신규격으로 전송할 수 있는 상태이다. 이러한, PCS(20)와 무선연결된 디지털오디오기기(10)내에는 PCS(20)에서 송신하는 데이터를 수신받기 위한 RS232C컨넥터(11)를 구비하며, RS232C컨넥터(11)에는 후단의 코덱(13)과의 인터페이스(INTERFACE)를 위해 인터페이스(12)를 구비한다. 인터페이스(12)의 출력단에는 녹음 및 재생을 위한 음성신호를 코딩 및 디코딩하는 코덱(CODEC)(13)이 연결된다. 그리고, 코덱(13)은 마이콤(14)과 입출력가능하도록 연결되며, 플레쉬메모리(FLASH MEMORY)(15)는 마이콤(14)의 제어를 받아 코덱(13)으로부터 출력되는 데이터를 저장하도록 연결된다. 이러한 구성을 갖는 다운로드가능한 디지털오디오기기에 대한 동작을 구체적으로 설명한다.Figure is a block diagram showing a downloadable digital audio device according to an embodiment of the present invention. The digital audio device 10 shown in the drawing is connected to a personal mobile communication device, and is configured to wirelessly connect to a recently common PC (PERSONAL COMMUNICATION SYSTEM: PCS) and RS232C. In addition, the digital audio device 10 can be wirelessly connected to the PC via RS232C. In the embodiment of the present invention, the PCS 20 will be described as an example. Here, the PCS 20 is in a state capable of receiving digital audio data according to a user's request and transmitting the RS232C communication standard in consultation with service providers on the PC and the Internet. The digital audio device 10 wirelessly connected to the PCS 20 includes an RS232C connector 11 for receiving data transmitted from the PCS 20, and the codec 13 of the rear end is provided on the RS232C connector 11. An interface 12 is provided for the INTERFACE. A codec 13 for coding and decoding audio signals for recording and reproduction is connected to the output terminal of the interface 12. The codec 13 is connected to the microcomputer 14 so as to be input and output, and the flash memory 15 is connected to store data output from the codec 13 under the control of the microcomputer 14. The operation of the downloadable digital audio device having such a configuration will be described in detail.
도면에서, 디지털오디오기기(10)는 마이크(미도시)를 통해 유입되는 음성신호를 코덱(13)을 통해 코딩하여 플레쉬메모리(15)에 기록하기도 하고, 플래쉬메모리(15)에 저장된 음성신호를 마이콤(14)의 제어하에 독출하여 코덱(13)에서 코딩되기 이전형태로 디코딩한 후 스피커(미도시)를 통해 외부송출하여 사용자로 하여금 들을 수 있도록 재생한다. 이때, 원하는 노래를 PCS(20)를 통해 다운로드받고자 하는 경우를 일실시예로 설명한다.In the drawing, the digital audio coder 10 codes the voice signal flowing through the microphone (not shown) through the codec 13 to record the voice signal stored in the flash memory 15, or to store the voice signal stored in the flash memory 15. The device is read under the control of the microcomputer 14, decoded in a form prior to being coded by the codec 13, and then externally transmitted through a speaker (not shown) to be reproduced so that the user can listen to it. At this time, a case where the desired song is to be downloaded through the PCS 20 will be described as an embodiment.
우선, 사용자는 휴대하고 있는 PCS(20)로 해당서비스업체에 전화를 건다. 전화연결이 완료되면, "원하는 가수를 선택하십시요"라는 오퍼레이터의 음성에 따라 사용자는 전화기 키패드상에서 "김건모"를 한글입력한다. 그러면, "곡명의 시작 초성을 선택하십시요"라는 음성이 나오고 사용자는 "ㅊ"을 입력한다. 그러면, PCS액정화면에 "1.첫사랑 2.첫인상...." 등의 선택사항이 디스플레이된다. 사용자가 2번을 선택하면 "첫인상"이 선곡된다. 그후, "다운로드를 원하시면 1번 종료는 2번을 눌러주세요"라는 음성에 따라 사용자는 1번을 누른다. 그러면, 도면에 도시된 바와 같이 PCS(20)는 디지털오디오기기(10)로 김건모의 첫인상에 해당하는 디지털오디오데이터를 전송한다. 이때, 디지털오디오기기(10)와 PCS(20)는 무선인 RS232C통신규격으로 통신가능하게 된다. PCS(20)로부터 데이터가 전송됨에 따라 디지털오디오기기(10)는 RS232C컨넥터(11)를 통해 이를 수신받는다. RS232C컨넥터(11)는 PCS(20)로부터 디지털오디오데이터를 수신받아 인터페이스(12)로 출력한다. 인터페이스(12)는 RS232C컨넥터(11)로부터 인가되는 디지털오디오데이터를 코덱(13)으로 출력한다. 코덱(13)은 인터페이스(12)로부터 입력되는 디지털오디오데이터를 녹음가능한 형태로 코딩한다. 마이콤(14)은 코덱(13)에서 코딩된 디지털오디오데이터를 플래쉬메모리(15)에 녹음시킨다. 플레쉬메모리(15)는 마이콤(14)의 제어하에 코덱(13)으로부터 코딩된 데이터를 저장한다. 여기서, 플레쉬메모리(15)는 착탈가능한 분리형으로 디지털오디오기기(10)와 분리하여 버전업(VERSION UP)할 수 있으며, 디지털오디오기기(10)는 별도의 메모리를 삽입하여 사용할 수 있다. 위와같이, 본 발명의 디지털오디오기기는 사용자가 원하는 데이터를 PCS를 통해 간편하게 다운로드받을 수 있다.First, the user calls the service provider with the PCS 20 he is carrying. When the telephone connection is completed, the user inputs "Kim Gun Mo" on the telephone keypad according to the operator's voice "Please select the desired singer". Then you will hear the voice "Please select the starting consonant of the song name" and the user enters "ㅊ". Then, the choices such as "1.First Love 2.First Impression ...." are displayed on the PCS LCD screen. If the user selects 2, the "first impression" is selected. After that, the user presses 1 in response to the voice, "If you want to download, press 2 to exit 1". Then, as shown in the figure, the PCS 20 transmits the digital audio data corresponding to the first impression of Kim Gun Mo to the digital audio device 10. At this time, the digital audio device 10 and the PCS 20 are able to communicate by wireless RS232C communication standard. As the data is transmitted from the PCS 20, the digital audio receiver 10 receives it through the RS232C connector 11. The RS232C connector 11 receives digital audio data from the PCS 20 and outputs the digital audio data to the interface 12. The interface 12 outputs digital audio data applied from the RS232C connector 11 to the codec 13. The codec 13 codes digital audio data input from the interface 12 into a recordable form. The microcomputer 14 records the digital audio data coded by the codec 13 into the flash memory 15. The flash memory 15 stores data coded from the codec 13 under the control of the microcomputer 14. Here, the flash memory 15 is detachable and detachable from the digital audio device 10 and can be upgraded (VERSION UP), and the digital audio device 10 may be used by inserting a separate memory. As described above, the digital audio device of the present invention can easily download the data desired by the user through the PCS.
상술한 바와 같이, 본 발명에 따른 다운로드가능한 디지털오디오기기는 디지털오디오기기내에 RS232C통신규격에 맞는 컨넥터와 인터페이스를 구비하여 별도의 케이블을 사용하지 않고 통신기기로부터 보다 간편하게 디지털오디오데이터를 다운로드받아 광범위하게 사용할 수 있으며, 개인휴대통신기기의 활용범위를 확장하는 효과를 제공한다. 물론, PC와도 RS232C를 통해 디지털오디오데이터를 다운로드 받을 수 있다.As described above, the downloadable digital audio device according to the present invention is equipped with a connector and an interface conforming to the RS232C communication standard in the digital audio device, so that digital audio data can be easily downloaded from a communication device without using a separate cable. It can be used and provides the effect of expanding the range of use of personal mobile communication devices. Of course, you can also download digital audio data via RS232C with your PC.
