Method for transmitting man-machine operation picture, mobile video device thereof, and video system using the same

A mobile video device, capable of transmitting a man-machine operation picture, the mobile video device comprising:

• a first screen, comprising a video buffer, wherein the video buffer stores a display picture data;
• a processor, for obtaining the display picture data from the video buffer, and converting the display picture data into a video data compliant to a video format;
• a data composition module, for obtaining the video data provided by the processor, and converting the video data into a binary data stream according to a video communication protocol;
• and
• a wireless module, for outputting the binary data stream to at least another mobile video device.

A video system, capable of transmitting a man-machine operation picture, comprising:

• a first mobile video device, comprising:
• a first screen, comprising a video buffer, wherein the video buffer stores a display picture data, and the first screen displays a first picture according to the display picture data;
• a first processor, for obtaining the display picture data periodically, and converting the display picture data into a video data compliant to a video format;
• a data composition module, for converting the video data into a binary data stream according to a video communication protocol;
• and
• a first wireless module, for outputting the binary data stream;
• and
• a second mobile video device, comprising:
• a second wireless module, for receiving the binary data stream;
• a data decomposition module, for converting the binary data stream into the video data according the video communication protocol;
• a second processor, for obtaining the display picture data carried in the video data obtained after a converting process of the data decomposition module;
• and
• a second screen, for displaying a second picture according to the display picture data obtained by the second processor, wherein the second picture substantially comprises the first picture.
