REAL TIME SCREEN CLONE APPARATUS OF MOBILE TERMINAL, THE SYSTEM AND METHOD THEREOF}

The present invention relates to a real-time screen player, a system, and a screen reproducing method of a mobile terminal. Particularly, real-time transmission is performed without delay by separately transmitting captured screen data and audio data of a mobile terminal through a local area network and Bluetooth communication, respectively. The present invention relates to a real-time screen player of the mobile terminal, a system thereof, and a screen playback method.

Background Art A technology of wirelessly transmitting screen images and audio of a computer or a mobile terminal to another computer or a mobile terminal has been conventionally known.

As a method of transmitting image data to another computer or a terminal, it is common to capture a screen, compress it in a predetermined format such as JPEG or MPEG, and then convert the image data.

This is because it is difficult for a screen transmission program to directly receive a video signal or an audio signal currently played by a computer or a terminal due to an operating system limitation.

Accordingly, a method of copying or reproducing video and audio currently displayed on a predetermined computer or terminal to another computer or terminal in real time, and capturing the image data and audio data, synchronizing them to a predetermined format, and then compressing and converting them to a predetermined format. The real-time transmission to another computer or terminal and the reproduction method of the received computer or terminal has been mainly used.

However, in the case of transmitting a high resolution or high capacity video and audio data, the conventional real-time screen player transmitting wirelessly consumes a lot of resources of the terminal in synchronizing, compressing, and converting video and audio during a format conversion process. Due to limitations, a disconnection phenomenon or a delay phenomenon occurs in which a screen of a terminal to be played back becomes slower than a screen of a terminal to be transmitted.

For this reason, in the related art, there have been many limitations in transmitting screen contents and audio displayed on a mobile terminal to other terminals in real time and reproducing them without delay or interruption, in particular, using a wireless network.

Accordingly, there is a need for a real-time screen player capable of wirelessly transmitting video and audio displayed on a predetermined mobile terminal in real time without delay or interruption.
