Abstract
A method and apparatus for transmitting a packet-based image frame, the method including: dividing an input image into intra and inter prediction frames and encoding the intra and inter prediction frames; applying different error resilience algorithms to the intra and inter prediction frames; and performing forward error correction (FEC) on the intra and inter prediction frames according to the corresponding error resilience algorithms. According to aspects of the present invention, optimal error correction may be performed in accordance with characteristics of frames when image data is transmitted. Thus, a strong image streaming service for preventing errors of a mobile environment may be implemented simply and efficiently.
