The present invention relates to a video providing apparatus, and more particularly, to a video providing apparatus for providing a video lecture to a personal panel using a projector.

As the technology develops, the life patterns of modern people are also changing. In the past, most people visited the institute to register for the lecture they wanted and took the lecture according to the designated time. However, with the development of technology, various video playback devices have been developed, and more people are taking video lectures using these video devices.

Currently, various video reproducing apparatuses used by users to listen to video lectures include terminals capable of Internet or PC video storage such as PCs, laptops, PMPs, PDAs, mobile phones, and MP3s.

An internet-enabled device such as a PC or laptop can download video data from a video providing site, play video lectures on a monitor through streaming, and store and move video data such as PMP, PDA, mobile phone, and MP3. A portable terminal that can be viewed is connected to a PC or a laptop, and stores downloaded video data and plays it on the screen.

When using the above-described video playback device, there is an advantage in that it is possible to self-develop the desired lecture anytime and anywhere during leisure time in a busy schedule and to repeatedly watch the desired part, but there are the following problems. .

First, if the user does not have a learning material corresponding to the video lecture, it is difficult for the user to follow the lecture. Most video lectures are produced on the premise that the user has a learning material, so the contents of the learning material are not included. When listening to such a lecture without learning materials, the user has a problem that it is difficult to understand the contents and difficult to concentrate.

Second, when viewing the video playback screen and learning materials together, it is difficult to focus on one place. Since the user cannot see the video playback screen and the learning material at the same time, the eyes should be moved frequently. As a result, if a user misses the contents of the video while taking notes, the user may not be able to write while viewing the video.

Third, eyesight problems may occur due to eyestrain during video playback. Due to the small size of the video playback screen of most portable terminals and the strong light generated by the monitors of PCs and laptops, watching video lectures for long periods of time can cause eye strain.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In order to more clearly understand the present invention, the same reference numerals are used for the same components in different drawings.

1 is a block diagram showing the configuration of a video providing apparatus 100 according to a first embodiment of the present invention.

The video providing device 100 includes an image projector 110, a connector 120, and a main body 130.

In addition, the image projector 110 projects the image signal input from the main body 130 to the user. In order to reduce eye fatigue, the image projector 110 uses a LED lamp to rotate the light received from the lamp. The light is transmitted through the color wheel to color the light, and the light from the DMD chip is reflected by a digitally controlled micro-mirror, and the projection lens can project an image on the principle of enlarging the light filtered by the DMD chip.

This configuration is a basic principle of a DLP (Digital Light Processing) projector currently on the market, and in the preferred embodiment of the present invention, the image projector 110 is implemented using the DLP.

In addition, since the image projector 110 may set the size of the projected image, the image projector 110 may set the size of the image to match the size of the material to which light is projected. In other words, the image size can be set according to various book standards such as national distribution, 4 × 6 distribution, or various paper standards such as A4, B4, B3, etc. You can have handwriting formats such as underscores and writings appear in place.

In addition, it is also possible to use only as a stand by projecting light only by selection.

The connection unit 120 may connect the main body 130 and the image projector 110 to adjust the height. This allows a user to set a convenient location for watching a video lecture.

The main body 130 receives and reproduces a learning data image signal, a writing data image signal, and an image signal combining learning data and writing data from a storage medium, and is fixed to an object to which light according to the image signal is projected.

These video signals are produced using the chroma key technique. In the chroma key technique, two cameras take a background and a foreground separately to obtain a foreground signal to be inserted at the output of the camera photographing the foreground and a signal to cut out the background. This cropping signal erases only the portion where the foreground image enters in the center of the image of the background signal, and puts the foreground to be put in the erased position.

At this time, the foreground of the chroma key is photographed on the background of the color of ultramarine blue, and only the image of the required foreground is obtained by removing only the color of the ultramarine blue. At the same time, the synthesized picture is completed by creating a signal in which parts and outlines of the picture are cut out equally.

That is, in the present invention, the blackboard writing content on the background of the special blackboard (ultramarine blue color or green color) and the video signal (foreground signal described above) containing the lecturer's appearance, and the learning material corresponding to the lecture content (background described above) Video signal) is produced. In addition, the special blackboard is removed, so that only the written contents and the lecturer's appearance are stored, and the written contents, the lecturer, and the learning material including the learning materials can be produced.

Objects to which light is projected according to an image signal may correspond to various objects on which learning materials (eg, textbooks, learning papers, printed matters, etc.) may be located. For example, a reading table or a desk may correspond.

It can be implemented in various forms, including forms. In this case, the storage medium includes a USB memory stick, a PMP, an MP3, a computer, a notebook computer, and a DVD player capable of realizing an image signal stored in a CD or a DVD.

In the case of a medium capable of Internet, such as a computer or a notebook, a program for easily controlling the video providing apparatus 100 may be installed, and the video file may be downloaded or played in the video providing apparatus 100 by streaming.

In addition, storage media such as a USB memory stick, PMP, and MP3 may play back the stored video file in the video providing device 100.

In addition, since a storage medium such as a CD or a DVD cannot be directly connected to the video providing device 100, a video stored in the CD and the DVD by connecting a medium capable of playing CDs and DVDs, such as a DVD player, to the device 100. The file may be played by the video providing device 100. In this case, the input unit 132 may be implemented in the form of a terminal such as S-VHS.

In addition, the input unit 132 may be upgraded to recognize firmware of various storage media as described above.

The controller 134 may select some of the input image signals, convert them into a suitable form through decoding, and reproduce and control the converted signals.

The input video signal is the above-described learning data video signal, writing data video signal, and video signal combining learning data and writing data generated through the chroma key technique.

In the case of the learning material video signal, it is useful when the user wants to learn with only the learning material without watching the video lecture, but does not have the learning material. In addition, in the case of a writing material video signal, the user possesses a learning material corresponding to the content of the lecture. Therefore, the writing material video signal can be used to reproduce and learn the writing material video signal on the learning material. Does not have any learning materials, but can be easily used when you want to learn the content of the lesson.

In the case of learning by selecting the writing material image signal, as shown in FIG. 3, since various writing formats such as underlining and writing are implemented, the user can write on the learning material accordingly.

When a video signal is selected according to a purpose from a user, the selected video can be played and controlled through a function of playing, stopping, selecting a next file, selecting a previous file, and fast forwarding.

The controller 134 may be implemented in the form of a plurality of buttons and keypads, but may be implemented in any form that is easy to control.

In addition, the controller 134 may capture a portion of the reproduced video signal. If a user wants to document something in the middle of learning, there has been a hassle to write by hand. However, by using the capture function of the present invention, it is possible to capture an image to be documented and easily document it through an output device such as a print.

The display unit 136 may display information and a reproduction state of a video signal to be reproduced. The information of the video signal may include a play file name, a file capacity, a remaining use period, and the like, and the play state may include all information that may indicate a currently playing state such as play time, play, stop, and rewind. .
