Description
The present invention relates to a content sharing system and a content sharing method using the same. More particularly, the present invention relates to a content sharing system and a method of sharing content using a wireless WiFi, such as a smart phone and a smart pad, Sharing, direct sending / receiving to a display device without connecting a separate notebook PC or personal PC to perform a presentation, and a USB memory or SD card to be directly connected to directly control stored pictures, And a content sharing method using the content sharing system.
As the performance and functions of portable terminals represented by smart phones and smart pads have improved, the computing power of portable terminals has reached the level of general PCs. However, due to the portability of portable terminals, the size of smart display devices is more than 5 inches, The pad is difficult to expand to more than 10 inches.
When using services such as cloud computing, Internet, video viewing, and presentation on a smart phone, it is possible to enhance the utilization of the portable terminal if the external display device such as a beam projector, a TV, and a PC monitor is easily utilized.
Presentations and lectures by linking smart phones or smart pads with various large display devices that can be used in the field without having to carry separate devices such as a notebook PC or an external hard disk. It is possible to share contents such as moving images and still images.
A mobile interface device between a mobile terminal and an external display device using wireless communication, which was registered in the Korean Intellectual Property Office (KIPO) No. 10-0581057, has been published on May 16, 2006.
In order to attain the above object, the present invention provides a mobile interface device between a mobile terminal and an external display device using wireless communication according to the present invention, in which a Bluetooth or an infrared port is set for a mobile terminal in which a Bluetooth or an infrared port is set 1. An interface device between a computer and an external display device connected directly or via a network to the computer, the device comprising: a wireless communication functional unit (110) for performing communication with a mobile terminal equipped with a Bluetooth or infrared module; A memory 130 for storing data received from the wireless communication function unit 110, a memory 130 for storing data received from the wireless communication function unit 110, a file for displaying on the liquid crystal of the external display device, Whether the file is for transferring commands such as page navigation A received file conversion unit 140 for converting the received file into data for display on a liquid crystal display of an external display device, A display unit 150 for displaying the converted file through the received file conversion unit 140 on the liquid crystal of an external display device, a display unit 150 for displaying the converted file on the liquid crystal display of the external display device, And a central control unit 180 which is electrically connected to the units and controls overall control of the units.
However, the above-described conventional technology has a disadvantage in that the communication speed of the mobile communication terminal is limited to Bluetooth and infrared communication, the data communication speed is limited, and the current content display speed and display quality are very poor.
Recently, a technology that is commonly applied to use a secondary display device using a smart phone or a smart pad is a mirroring technology. This technology is a technique of sharing a content by mirroring a screen reproduced from a portable terminal with an external display Method.
1. System privileges
Since the system authorization is required to apply the mirroring technology to the smartphone or the smart pad, the official approval of the smartphone manufacturer is required. Therefore, there is a problem in that a product without the official approval of the manufacturer has to forcibly execute the smart phone rooting, This may cause malfunction of the smartphone and normal free repair of the routed mobile phone is impossible.
2. Image delay and sync inconsistency
In the mirroring method, there is a limitation of the transmission bandwidth when the external device and the WiFi are interlocked. Therefore, the reproduction of the external display of the full HD video may be delayed or the synchronization of the video and audio may be inconsistent.
3. Restrictions on Content
Mirroring method is a method of mirroring the screen played on the smartphone or smart pad app, so there is no problem in playing video or still image. However, most of the document playback such as Microsoft PowerPoint, Excel, Word You must install a separate viewer for paid apps.
4. Limitations of resolution
The resolution of the mirroring method is adjusted to the screen resolution of the mobile phone irrespective of the H / W specification of the external display, so that the screen ratio is inconsistent or a part of the screen is cut off.
5. Problems with content security
Since various documents protected by content security software are set to restrict the screen hard copy function, it is impossible to reproduce them on the external display by the mirroring method.
Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a portable wireless terminal, A contents sharing system of a portable terminal configured to directly transmit and receive a picture, a moving picture, and a document by directly transmitting and receiving a presentation to a display device without connecting a personal PC and configuring a USB memory or an SD card to be directly connected And a content sharing method using the same.
In order to achieve the above-described object of the present invention, the following technical features are provided.
To overcome the display limitation of smartphone or smart pad, it is a device for outputting photos, videos, documents, etc. of smart phone, smart pad or portable external storage device to external display such as TV, PC monitor and beam projector , The file is transferred to the wireless WiFi instead of the mirroring method to share the content.
It is a device that makes use of smart phones or smart pads only in the business scene and enables business activities such as presentations, lectures and explanations by utilizing external displays without the help of equipment such as a separate notebook PC.
In addition, it accepts USB memory (USB Flash Drive) or SD card (MICROSDHC), which is the most common medium for carrying files, and can control the contents recorded in the external storage device by using a smart phone or smart pad without needing a separate notebook PC. .
Since the Smart Contents Share function according to the present invention plays video, still image, voice, and various documents on its own, it can reproduce various document type contents such as Microsoft PowerPoint which can not be accommodated in the mirroring method Suitable.
