1. An electronic device for transmitting a bitstream containing information on an image having a first image ratio that is longer horizontally than vertically to a terminal to enlarge and reproduce the image when the terminal has a screen ratio that is longer vertically than horizontally, the electronic device comprising:
an analysis controller configured to analyze contents of a corresponding frame image for each frame of the image to calculate a reproduction area corresponding to a part of the corresponding frame image;
a selection controller configured to separate the image into a plurality of subunits, and select an optimal artificial intelligence (AI) model applied for each subunit according to the contents of the image within the corresponding subunit from among a plurality of AI models previously trained for each type of contents of the image; and
a generation controller configured to generate the bitstream including information on the image, the reproduction area, and the optimal AI model, respectively.
