Title: Method for transmitting and receiving a variable size packet based on foward error correction coding
Inventor: KIM GYU HEON
IPC: H04L1/18
Filed: 2002-05-03
Abstract: PURPOSE: A method for transmitting/receiving variable-length packets on the basis of an FEC(Forward Error Correction) coding system is provided to minimize transmit delay by creating a parity packet for a variable-length packet virtually connected to a 2-dimensional storage device without the process of padding and directly transmitting a data packet without the necessity of inputting all the packet groups associated for the creation of the parity packet. CONSTITUTION: If a data packet is inputted, a transmitting side accumulates the value of a factor that determines whether a parity packet is to be transmitted(S201), and connects the data packet to a 2-dimensional storage device virtually(S202). After updating a relevant parity packet every time a data packet is inputted, the transmitting side transmits an expanded data packet, containing a data packet and information for the restoration of the data packet, to a receiving side(S204). Then the transmitting side determines whether it is time to transmit parity packets(S205). In case that it is judged that it is time to transmit parity packets, the transmitting side determines the number of parity packets to be transmitted(S206). Then the transmitting side compares the number of transmitted parity packets with the determined number(S207). If the number of transmitted parity packets is smaller than or equal to the determined number, the transmitting part transmits expanded parity packets(S208) and accumulates the number of transmitted parity packets(S209).
