Data transmitting/receiving system and method thereof
A data transmitting/receiving system adds identifying information to a data packet based on characteristics of the data. The identifying information can be a data type of a payload data of an IP/UDP/RTP packet and/or a temporal data sequence of the payload data. The IP/UDP/RTP packet added with the identifying information is segmented into an IP/UDP/RTP header and IP/UDP/RTP data. The segmented IP/UDP/RTP header and the IP/UDP/RTP data can be transmitted through different channels. A receiver sends retransmission control information based on the added identifying information extracted by the receiver, the retransmission control information providing retransmission time and priority information. A transmitter retransmits reception error occurring IP/UDP/RTP data according to the retransmission control information received by the transmitter. Varying the retransmission times and/or retransmission priority based on the data characteristics, accommodates data retransmission so that data more influential to data restoration in case of loss/damage can be received more stably.
