Display device, display method, transmitting device and transmitting method

A display method comprising:

• receiving image data of a predetermined format for each frame;
• detecting an additional information disposed in a specific position of the image data of one frame received in the receiving of the image data;
• extracting division image of a still image disposed in the image data of one frame received in the receiving of the image data, synthesizing the extracted division images based on the additional information and assembling the still image greater than the number of pixels of the image data of one frame;
• and
• displaying the still image synthesized in the extracting of the division images.

A transmitting device comprising:

• a division processing unit that obtains data of a plurality of division images by dividing the image data of one still image for each predetermined area and disposing each of the obtained data of the plurality of division images in image data of a predetermined format having the number of pixels less than that of the still image;
• an information addition unit that disposes additional information on division images in a specific position within the image data of the predetermined format obtained in the division processing unit;
• and
• a transmitting unit that outputs whole produced frames while the additional information unit outputs repeatedly frames in which the additional information is disposed multiple times for each division image.

• disposing additional information on division images in a specific position within the image data of the predetermined format obtained in the obtaining;
• and
• outputting whole produced frames while repeatedly outputting frames in which the additional information is disposed multiple times for each division image in the disposing.
