Mirror display system having low data traffic and method thereof

A mirror display system having low data traffic, comprising:

• a transmitting-end device, comprising:
• a first wireless transceiver;
• a human machine interface displaying images and receiving a page-selecting operation;
• a first memory storing the first file;
• and
• a first processor electrically connected to the first wireless transceiver, the human machine interface and the first memory, comprising:
• a first transforming module reading and transforming the first file into a plurality of the first page images;
• and
• a first processing module connected to the first transforming module, selecting one of the plurality of first page images according to the page-selecting operation, transmitting the selected first page image to the human machine interface for displaying and externally transmitting an identifying page data of the selected first page image via the first wireless transceiver;
• and
• a receiving-end device connected to a display module, and comprising:
• a second wireless transceiver receiving the identifying page data from the transmitting-end device;
• a second memory storing a second file, wherein the second file and the first file having the same content;
• and
• a second processor electrically connected to the first wireless transceiver and the second memory, comprising:
• a second transforming module reading and transforming the second file into a plurality of the second page images, wherein the plurality of the second page images respectively corresponding the plurality of the first page images;
• and
• a second processing module connected to the second transforming module, selecting one of the plurality of second page images according to a page-selecting operation, and transmitting the selected first page image to the display module for displaying, wherein the selected second file image and the selected first file image having the same content;
• wherein the first processor further comprises a first zooming module connected to the first processing module, adjusting the visual range of the first page image currently displayed on the human machine interface according to a screen zooming operation received by the human machine interface, and calculating zooming control data according to the adjusted visual range of the first page image;
• the second processor further comprises a second zooming module connected to the second processing module, adjusting the visual range of the second page image currently displayed on the display module according to the zooming control data.
