The present invention discloses a method and an apparatus of wireless video transceiving based on a multi-carrier technique. The method comprises the following steps: image information in a video GOP are separated and a sequential relationship between individual image information is recorded; general image information and important image information are treated discriminatingly in a video transmission process according to the degree of importance of different image information, in order to improve a transmission quality of the important image information; after the image information is received by a receiving end, the image information is recombined into the video GOP according to the sequential relationship. In the present invention, the important image information and non-important image information are treated discriminatingly via a sub-carrier allocation and a selection of different transmitting conditions in order to enhance the transmission quality of important image information in terms of improving the transmitting condition, so that the transmission quality of the wireless video is guaranteed.
