Abstract

PURPOSE: An image communication system using a modulation algorithm of an audio and a video on the wire and wireless Internet is provided to keep a privacy between a consumer and a counselor through the modulation function of the audio and the video. CONSTITUTION: A communication server includes a server engine, a client database, and a communication room list database. A user terminal includes a wire and wireless terminal, such as a PC(Personal Computer), a PDA(Personal Digital Assistant), and a handy phone, and the like, mounted audio and image effect filters. A connection management module is a program module for connecting to a server and a room and for releasing the room. The image effect filter provides a mosaic effect, a chromatograph synthesis of a background screen and processes in real-time the image. The audio effect filter is a real-time voice modulation engine for operating a volume and the speed of sound. An audio decoder releases and outputs a compression of received audio data. An image decoder releases and outputs the compression of received image data.

Description

음성 및 화상의 변조 알고리즘을 이용한 유무선 인터넷상의 화상통신시스템{Audio/Video Effect Filter applied to Communication System on Mobile and Internet Network}Audio / Video Effect Filter applied to Communication System on Mobile and Internet Network}

첫째, A/V의 Effect기능을 통해 사용자의 음성과 화상이 새로운 모습으로 다양하게 구사되어 화면에 나타나므로 일반적인 화상채팅에서 사용자 실물의 선정적인 노출로 인해 야기될 수 있는 음란과 폭력으로부터 자신을 보호할 수 있다.First, through the A / V Effect function, the user's voice and video are displayed in various ways on the screen, thus protecting themselves from indecent and violent violence that may be caused by the user's sensational exposure. can do.

둘째, A/V의 Effect 기능은 익명성과 사실감의 혼합적 성격을 띄게되어 가상의 공간을 통한 만남이라는 인터넷의 특성과도 잘 부합되므로 자신을 화면그대로 노출시키기 꺼려하는 사용자들의 부담감을 덜어줄 수 있다.Second, the effect function of A / V has a mixed nature of anonymity and realism, so it is well matched with the characteristics of the Internet such as meeting through virtual space, which can ease the burden of users who are reluctant to expose themselves to the screen. .

셋째, 본 화상채팅의 기본기능 및 A/V Effect 응용기능을 향후 웹메일, 웹메신저와 SMS(Short Message Service), 차세대 이동통신 시스템과도 연동하여 자유롭고 다양한 형태의 서비스로 확대, 여러 가지 비즈니스와 서비스에 응용될 수 있는 기술적 기반을 구축하고자 한다.Third, the basic function of this video chat and A / V Effect application function will be extended to free and various types of services by interworking with web mail, web messenger, short message service (SMS), and next generation mobile communication system. We want to build a technical foundation that can be applied to services.

기존의 음성채팅, 화상채팅, 화상 메신져, 화상미팅, 화상전화, 화상상담등의 화상통신 시스템들은 전적으로 사용자의 실제 화상 및 음성을 그대로 전송해서 보여주는 시스템이다. 따라서 사용자는 자신의 음성을 드러내기를 꺼려하여 문자입력을 통한 대화를 주로하지만 문자 입력이 서투른 사람은 서비스를 이용하기를 꺼리게 된다. 동화상이 화상 카메라를 통해 생생히 전달되므로 카메라를 벽쪽으로 향하게 하는 경우와 아예 카메라의 전원을 끄는 경우도 발생하고 있다. 이러한 원인은 인터넷이라는 가상의 공간에서 모르는 사람과의 화상통신 시스템을 통한 만남 서비스를 이용하는 상황이기 때문이다.Existing video communication systems such as voice chat, video chat, video messenger, video meeting, video call, video consultation, etc. are completely transmitted and show the actual video and audio of the user. Therefore, the user is reluctant to reveal his or her voice, and mainly communicates through text input, but a person who is not good at text input is reluctant to use the service. Since moving images are vividly transmitted through the image camera, there are cases where the camera is turned toward the wall and the camera is turned off. This is because in the virtual space of the Internet using a contact service through a video communication system with strangers.

본 발명은 화상통신 시스템에 접속한 사용자 자신이 사실감과 익명성의 정도를 조절하여 상대에게 보여주는 방법을 제공하여 프라이버시를 스스로 보호할 수 있는 것을 목적으로 한다. 따라서 음성 /화상의 필터링을 통한 다양한 Effect 기술과 변조된 음성 /화상의 동시 다자간 실시간 송수신 기술 이 요구된다.It is an object of the present invention to provide a method of controlling a degree of realism and anonymity by a user who is connected to a video communication system to show a counterpart to protect privacy. Therefore, various effects technologies through voice / picture filtering and simultaneous multi-party real-time transmission / reception techniques for modulated voice / picture are required.

본 발명은 이러한 목적을 달성하기 위하여 유무선 인터넷상에서 프라이버시 보호기능을 제공하는 화상통신 시스템 및 그 방법을 제시한다.The present invention provides a video communication system and a method for providing a privacy protection function on the wired and wireless Internet to achieve this object.

도1은 본 발명의 시스템이다. Communication 서버는 서버엔진, 고객 데이터베이스와 통신방 리스트 데이터베이스를 포함한다. 사용자 단말은 오디오 및 이미지 Effect Filter가 장착된 고객의 유무선 단말(PC, PDA, HandPhone등)을 포함한다.1 is a system of the present invention. Communication server includes server engine, customer database and communication room list database. The user terminal includes a customer's wired / wireless terminal (PC, PDA, HandPhone, etc.) equipped with an audio and image effect filter.

도2 메인흐름도에서 사용자는 Communication서버로 로그인한 후 통신방을 개설하거나 개설된 통신방에 접속한다. 통신방에서 본인의 프라이버시를 보호할 수 있을 정도의 오디오 및 이미지 Effect Filter 옵션을 선택하여 통화자와 화상통신을 한다. 도3 이미지 Effect Filter 흐름도는 사용자가 이미지 Effect Filter 선택화면에서 원하는 배경화면, 원하는 Effect Filter, 조절강도를 선택하면, 먼저 Effect Filter를 통해 변조된 화상을 다시 한번 배경화면과 크로마키 합성기법으로 합성되어 최종화면을 얻게 된다. 도4 이미지 Effect Filter 흐름도는 오디오 Effect Filter 선택화면에서 Echo, Pitch등을 선택하면 즉시 오디오 Effect Filter를 통한 변조된 음성을 얻게 된다.In the main flow diagram of FIG. 2, a user logs in to a communication server and opens or opens a communication room. Select the audio and image Effect Filter options that are sufficient to protect your privacy in the communication room and communicate with the caller. Fig. 3 is a flow chart of the effect filter, when a user selects a desired background image, a desired effect filter, and an adjustment intensity on an image effect filter selection screen, the image modulated through the effect filter is first synthesized by a background image and a chroma key synthesis technique. You will get the final screen. In the effect filter flow diagram, when Echo and Pitch are selected on the audio effect filter selection screen, a modulated voice is immediately obtained through the audio effect filter.
