Abstract: Provided is a decoding apparatus including: a communication interface configured to receive Al encoding data generated as a result of artificial intelligence (Al) down-scaling and first encoding of an original image; a processor configured to divide the Al encoding data into image data and Al data; and an input/output (I/O) device, wherein the processor is further configured to: obtain a second image by performing first decoding on a first image obtained by performing Al down-scaling on the original image, based on the image data; and control the I/O device to transmit the second image and the Al data to an external apparatus. In some embodiments, the external apparatus performs an Al upscaling of the second image using the Al data, and displays the resulting third image.
