Abstract:
1. A server to determine error restoration according to image data transmission, the server comprising: a forward error correction (FEC) mode performer to output image data in which at least one redundant bit for error correction is added; an automatic repeat request (ARQ) mode performer to output the image data after receiving a response signal according to data reception from a client that receives the image data; a mode determiner to determine whether to operate in an FEC mode or an ARQ mode so that error restoration is performed on the image data based on a reception buffering capacity of the client in regard to the image data; and an interface to transmit image data outputted from the FEC mode performer or the ARQ mode performer to the client, wherein the mode determiner determines to perform the error restoration using the ARQ mode when the reception buffering capacity is greater than or equal to a predetermined value and determines to perform the error restoration using the FEC mode when the reception buffering capacity is less than the predetermined value.
