Description

Telecommunication Lecture System and Method {Home Study System and Method by Communication}

The present invention allows a student to simultaneously view a lecture or a lecture record, which is voice or video, and a lecture writing, by using the Internet or an airwave television broadcast from a remote location by wire or wireless. The present invention relates to a communication lecture system and method.

Globally, there is a growing need for instructors and attendees to teach to a large number of remote or unspecified participants.

Because of this necessity, educational broadcasting using TV broadcasting and internet lecture using internet are being conducted.

In general, a lot of language classes such as entrance exams for elementary and middle school students, employment for adults and college students, and English are widely used on the Internet. By the way, the conventional method of teaching on the Internet includes a method of learning by using an Internet lecture using a multimedia or an offline learning using a CD-ROM for learning and finding a learning result online.

By the way, the learning using the CD-ROM as described above, the person who wants to listen to the lesson or lecture must not only purchase the CD-ROM but also the learner purchases a separate learning CD and installs it on the user's terminal. It is supposed to conduct learning through 1: 1 conversation through E-MAIL. This method has its advantages because of the limitations of the method and system of the Internet lecture, which is widely used. In addition to targeting a small number of participants, lecture content is also an inappropriate method for delivering advanced knowledge.

In the case of Internet lectures using multimedia, because the current Internet transmission speed is low, the connection is frequently disconnected or the size of the video screen is separate, but the lecturer writes on the blackboard due to the limitation of the screen size of the student's PC monitor. It is not uncommon to not know the contents.

Therefore, there is a problem in that lectures in mathematics or other science courses are incomplete in teaching the Internet.

Internet lecturers can not write effectively because they can not write, and even those who listen to the Internet does not understand the contents of the lecture enough to listen to the language-only lecture.

In addition, there is the same problem with the Internet lectures using multimedia among the above Internet lectures. The TV processes the content to be written as subtitles or creates a separate lecture chart and displays it on the receiver screen with a TV camera. Although the above problem is solved, the above problem cannot be completely solved.

As described above, the present invention has been devised to solve a problem in a lecture for communication education via wired or wireless internet or TV remotely.

The first object of the present invention is to provide a moving picture of the lecturer's lecture on the monitor of the lecturer so that the learner can easily listen to the lecture contents while watching the written contents in the lectures conducted on the Internet, or to see and hear the lecture. Or, it is characterized in that the lecture book can be read by displaying or viewing the lecture book while simultaneously watching or listening to the voice.

Another second object of the present invention is to allow a person who takes a lecture on TV to fully understand the contents of the lecture by watching the written content of the lecture in a separate window. .
