이하에서 첨부한 도면을 참조하여 본 고안의 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안에 의한 인터랙티브시스템의 구성블럭도로서, 디스크(11), 픽업(12), 음성신호재생부(13), 화상신호재생부(14), 음성신호기록부(15) 및 화상신호기록부(16)를 구비한다.1 is a block diagram of an interactive system according to the present invention, which includes a disk 11, a pickup 12, an audio signal reproducing unit 13, an image signal reproducing unit 14, an audio signal recording unit 15, and an image signal. The recording unit 16 is provided.
디스크(11)는 CD-DA, CD-G, CD-FMV 뿐만아니라, CDI-FMV로 화상전화의 영상 및 음성데이타를 기록 및 재생 가능하도록 한다.The disc 11 makes it possible to record and reproduce video and audio data of a videophone with CDI-FMV as well as CD-DA, CD-G and CD-FMV.
픽업(12)은 디스크(11)에 기록된 데이터를 정확하게 읽어 프리앰프(131)로 전송하여 신호를 재생하게 하거나, 기록하고자 하는 정보의 신호를 레이저빔에 의하여 디스크(11)에 기록할 수 있도록 한다.The pickup 12 accurately reads the data recorded on the disk 11 and transmits the data to the preamplifier 131 to reproduce the signal, or to record the signal of the information to be recorded on the disk 11 by a laser beam. do.
음성신호재생부(13)는 픽업(12)에서 검출된 미약한 신호성분을 프리앰프(131)에서 일정레벨로 증폭하고, 디지타이징(Digitizing)부(132)에서 증폭된 신호를 일정레벨의 디지탈신호로 변환하고, DSP(Digital Signal Processor)부(133)에서 디지탈신호를 처리하여, 디지탈-아나로그변환기(Digital-Analog Converter)(134)를 통하여 음성신호를 사용자에게 전달한다.The audio signal reproducing unit 13 amplifies the weak signal component detected by the pickup 12 to a predetermined level in the preamplifier 131, and amplifies the signal amplified by the digitizing unit 132 to a predetermined level of digital signal. The digital signal is processed by the digital signal processor (DSP) unit 133 to process the digital signal, and the voice signal is transmitted to the user through the digital-analog converter 134.
화상신호재생(14)는 픽업(12)에서 검출된 미약한 신호성분을 프리엠프(131)에서 일정레벨로 증폭하고, 디지타이징(Digitizing)부(132)에서 증폭된 신호를 일정레벨의 디지탈신호로 변환하고, VSC(Video Signal Controller)(141)에서 영상신호를 처리하고 디지탈필터(142)와 디지탈-아나로그변환기(143)를 거쳐, 비디오인코더(Video Encoder)(144)에서 아나로그영상신호를 출력한다.The image signal reproduction 14 amplifies the weak signal component detected by the pickup 12 to a predetermined level in the preamplifier 131, and converts the signal amplified by the digitizing unit 132 into a digital signal of a predetermined level. The video signal is processed by the video signal controller (VSC) 141, and the analog video signal is received by the video encoder 144 through the digital filter 142 and the digital-analog converter 143. Output
음성신호기록부(15)로 입력되는 음성신호는 아나로그신호와 디지탈신호로 구분할 수 있으며, 아나로그입력신호는 아나로그-디지탈 변환기를 통하여 디지탈신호로 변환된다.The voice signal input to the voice signal recording unit 15 can be classified into an analog signal and a digital signal, and the analog input signal is converted into a digital signal through an analog-digital converter.
음성신호기록부(15)는 입력되는 음성신호를 EFM(Eight-to Fifteen Modulation)부(151)에서 변조하고, 에러정정부호화부(ECC)(152)에서 에러정정을 위한 부호를 부가한 다음, 레이저변조부(153)에서 디스크(11)에 기록할 수 있는 신호로 변조하여, 픽업(12)에서 디스크(11)에 음성신호를 기록한다.The voice signal recording unit 15 modulates the input voice signal in the EFM (Eight-to Fifteen Modulation) unit 151, adds a code for error correction in the error correction coder (ECC) 152, and then The modulator 153 modulates the signal to be recorded on the disk 11, and the pickup 12 records the audio signal on the disk 11.
화상신호기록부(16)는 화상전화송신기(도시되지 않음)에서 통화하고자 하는 상대방에게 영상신호데이타와 음성신호데이타를 전송하면, 화상전화수신기(161)에서 전송된 신호를 수신하여 음성신호와 영상신호를 분리 처리한다.When the video signal recording unit 16 transmits the video signal data and the audio signal data to the other party to be called by the video telephone transmitter (not shown), the video signal receiver 161 receives the signal transmitted from the video telephone receiver 161 to receive the audio signal and the video signal. Separate the process.
그리고, 음성신호처리부(162)와 영상신호처리부(163)를 통하여 디스크에 신호를 기록하기 위하여 입력되는 음성신호와 영상신호는, EFM 변조부(151)에서 변조되고 에러정정부호화부(152)에서 에러정정을 위한 부호를 부가한 다음, 레이저변조부(153)에서 디스크(11)에 기록할수 있는 신호로 변조하여 픽업(12)에서 디스크(11)에 영상신호를 기록한다.Then, the audio signal and the video signal inputted to record the signal on the disk through the audio signal processor 162 and the video signal processor 163 are modulated by the EFM modulator 151 and the error correcting encoder 152. After adding a code for error correction, the laser modulator 153 modulates the signal into a signal that can be recorded on the disk 11, and records the video signal on the disk 11 in the pickup 12.
영상신호처리부(163)는 영상신호가 동화상으로 전송되므로 동화상에 대하여 규정된 MPEG1으로 처리하도록 시스템을 구성한다.The video signal processing unit 163 configures a system to process the video signal to MPEG1 defined for the video since the video signal is transmitted as the video.
따라서, 화상전화의 데이터를 디스크에 기록함으로써, 송화자가 전달하고자 하는 의사내용 및 상대방의 모습을 재생하여, 상대방이 전달한 정보를 시간이 흐른 뒤에도 인터랙티브하여 볼 수 있다.Therefore, by recording the data of the videophone on the disc, the intention of the talker and the appearance of the other party can be reproduced, and the information transmitted by the other party can be interactively viewed even after time passes.
상술한 바와 같이 본 고안에 의하면, 콤팩트디스크 관련 기기를 이용하여 음성신호 및 영상신호를 기록 및 재생 가능하도록 구성하여 사용자가 정보를 알아보고자 할 때, CDI-FMV로 화상신호의 기록 및 재생을 동화상태로 인터랙티브하여 디스프레이 장치로 볼 수 있음으로써, 사용자가 원하는 시간에 필요한 정보를 인터랙티브기기를 통하여 제공받을 수 있는 잇점이 있다.As described above, according to the present invention, when a user wants to know information by configuring a compact disk related device to record and play back audio signals and video signals, CDI-FMV assimilates recording and reproduction of image signals. By being interactive with the state and viewing with the display device, there is an advantage that the user can be provided with the information necessary at the desired time through the interactive device.
