Abstract
Provided are a data transmission apparatus and method which apply an appropriate coding rate according to significance of bits or bit groups included in uncompressed data and retransmit all or part of the data when a transmission error occurs in the data while the data is being transmitted over a wireless network. The data transmission apparatus includes a mode termination unit which determines a retransmission mode for an initial transmission packet which has a transmission error; a packet generation unit which generates a retransmission packet, which includes at least part of the initial transmission packet, according to the determined retransmission mode; and a communication unit which transmits the retransmission packet through a communication channel.
