PURPOSE: Coding rate control, an unequal error protection application method and a video transceiving device using the same are provided to apply unequal error protection according to the property of a frame by optimally adjusting video/channel coding rate through a channel capacity estimation value if the channel capacity estimated from a video receiving device is received. CONSTITUTION: A channel capacity estimation value fed back from a video receiving device is predicted as the channel capacity of the next channel section(312). Video coding rate and channel coding rate are adjusted within the predicted channel capacity(314). Video frames are encoded with the adjusted video coding rate, and video packet is generated(316). An unequal error is protected considering the length of the video packet and the kind of the video frame included in the video packet(318). The video packet which the unequal error is protected is encoded with the adjusted channel coding rate and bit stream is generated(320).
