Abstract

The present invention relates to a music and image lecture system. In an online lecture, audio is provided using a separate wired telephone or an internet telephone network, and video is provided using an existing online network and sound of the video is muted such that a sound delaying phenomenon in an online video lecture can be solved by separately using a video and audio online networks.

Description

[0002] System for lecturing music and picture [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music and image lecture system, and more particularly, to a music and image lecture system for solving a sound lag phenomenon in on-line lecture by using an on-line network of voice and image.

The conventional online video lecture system prepares a separate computer and a web cam, prepares an audio system and a headphone separately, and performs an image lecture.

However, the conventional on-line picture lecture has a problem that it is impossible to lecture while playing a song or an instrument simultaneously due to a sound delay phenomenon.

That is, in the conventional image lecture, when a song or a musical instrument is simultaneously played due to a sound compression phenomenon, the sound of the other party can not be heard, so that it is impossible to lecture the music and the problem of the musical axis phenomenon can not be eliminated And there is a problem that a plurality of people can not access the lecture at the same time even in a linguistic or general picture lecture.

Also, in the conventional on-line picture lecture, there is a problem that the sound delay phenomenon can not be removed due to a large amount of data of the picture portion.

SUMMARY OF THE INVENTION The present invention has been made to solve the above conventional problems, and it is an object of the present invention to provide an on-line video loudspeaker which uses a separate wired telephone or an Internet telephone network, The present invention provides a music and video lecture system capable of solving a sound lag phenomenon in an image lecture by using an on-line network of video and audio.

That is, a key object of the present invention is to separately transmit and receive video and audio signals to solve sound delay and sound compression phenomenon in audio.

Another object of the present invention is to provide a music and image lecture system capable of solving the sound compression phenomenon by setting and operating professional sound devices such as vocal microphone, audio mixer, and headphone for studio by the skill of a professional engineer.

These and other objects of the present invention will be apparent to those skilled in the art without departing from the scope of the present invention by the appended claims.

According to an aspect of the present invention, there is provided a music and video-

According to the music and image lecture system of the present invention, in the online image lecture, the voice is used by a separate wired telephone or the Internet telephone network, and the image is used by using the existing online network and muted, And the phenomenon can be solved by using an on-line network of video and audio separately.

Additional features and advantages of the present invention will become more apparent from the following description.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 shows a schematic configuration of a music and video lecture system according to an embodiment of the present invention; Fig.
Fig. 2 and Fig. 3 are views showing examples of installation of a music and image lecture system according to an embodiment of the present invention; Fig.
Figures 4 and 5 illustrate embodiments of a music and video lecture system in accordance with an embodiment of the present invention.

Hereinafter, a music and video lecture system according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Also, in the present specification, the following embodiments and embodiments are to be considered as being illustrative and not restrictive, and the invention is not to be limited to the details given herein but is to be accorded with the scope of the appended claims and their equivalents, It can be changed to another embodiment.

For reference, FIG. 1 is a diagram showing a schematic configuration of a music and image lecture system according to an embodiment of the present invention, and FIGS. 2 and 3 are diagrams for explaining a music and image lecture system applied to a music and image lecture system according to an embodiment of the present invention Figs. 4 and 5 are views showing examples of a music and image lecture system according to an embodiment of the present invention. Fig.

As shown in FIG. 1, the present invention is a music and image lecture system for separately transmitting and receiving video and audio signals to solve a sound delay and a sound compression phenomenon in a voice, One LAN cable is connected to the computer for video, and the other LAN cable is connected to the Internet phone for voice.

Also, in case of voice, a general telephone line (KT) may be used, and in case of a general telephone line, it may be connected to a general telephone.

In addition, a telephone with a headset connection function that can be connected to a professional sound device is prepared. When a microphone / audio mixer / headphone is connected, the voice is also completed.

Meanwhile, in the operation of the music and image lecture system constructed as described above, two persons, which is the minimum number for lecturing, must implement the system viewed in different spaces. For convenience, the first person performer is divided into the lecturer, the second person party is divided into the learner .

That is, as shown in FIG. 2 and FIG. 3, after the webcam is installed, the video call program (Skype) which can be used for free is activated and the voice signal is separately connected to the webcam The installed micro-received voice signal is not mixed.

At this time, the audio signal of the video call must be muted because the music lecture is impossible because of the sound delay / compression phenomenon.

Then, the voice is connected to the cable for separating the transmission signal and the reception signal from the headset terminal of the telephone, and then connected to the audio mixer, respectively.

At this time, the voice of the instructor is connected to the input channel (ex.1 channel) of the mixer through a high-performance microphone, and is connected to a separate output (ex.AUX1) of each channel of the mixer and is transmitted to the other party through the telephone.

In addition, the student's voice is routed from the receiving cable to the other input channel of the mixer (ex.4 channel), which is connected to the main output of the mixer via a speaker or headphone, allowing the performer to hear.

Also, the lecturer 's upbringing (song) and accompaniment (ex. Piano) must be separately input to solve the sound compression phenomenon. The microphone channel for upbringing should be input 1, the piano 2/3 times, etc .. separately.

4 and 5, the components such as a webcam, a computer, a telephone, an audio mixer, a microphone, and a headphone are used as a single product when actually used. It should be easy to configure and use.

This integrated product is called "M to M" (Music to Music) because it is specialized in music video lectures, and the integrated SMT product is connected to both a video and a voice when only a LAN cable is connected, And headphones / speakers should also be easily configured.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
