초록 ▼

The Universal Packet Loss Recovery System (UPLRS) is capable of recovering end-to-end network packet losses to obtain reliable end-to-end network delivery of multimedia streaming content over IP networks where packet losses appear above the transport layer. The UPLRS incorporates the use of Packet Forward Error Correction Coding (FEC) with packet interleaving processing prior to transport. Packet FEC is an error correction coding method at the packet level to improve link transmission reliability. At the source end of the packet-switching network, the Packet FEC scheme encodes a stream of transport multimedia content packets by including redundant packets in the stream to allow for the recovery of lost packets by the Packet FEC decoder at the user end of the packet-switching network. Since lost packets appear only above the transport layer in the IP network protocol stack, Packet FEC can be viewed as a transport layer or an application layer coding method.

1. A method of Packet Forward Error Correction Coding, operable in a packet switching network that serves to transmit data packets from a source to a destination, for encoding a stream of data packets received from a source by including redundant codeword packets in the stream of data packets transmitted to said destination to allow for the recovery of corrupted data packets by the decoder of said Packet Forward Error Correction Coding scheme located at said destination, comprising: storing a predetermined plurality of fixed length data packets, received from said source, as rows of an array;subdividing said array of data packets into a plurality of sequential frames;preprocessing each of the rows of all of said plurality of sequential frames with a single check parity code to create a single parity packet for each row of said plurality of sequential frames, for the purpose of correcting single packet losses that may appear in transmission of one of the row of frames in the packet array across said packet switching network;storing the generated single parity packets in a frame appended to the array of data packets;encoding each column of said array of data packets and said frame of parity packets with an error correction code to create at least two codeword packets which are used by said decoder of said Packet Forward Error Correction Coding scheme located at said destination to recover corrupted data packets of said array of data packets;appending said at least two codeword packets created for each column to a corresponding column of the array of data packets and said appended parity frame;transmitting said array of data packets, said frame of parity packets and said codeword packets to said destination via said packet switching network;at the destination: storing the received array of data packets, said frame of parity packets and said codeword packets;inserting a null packet consisting of a row of empty slots when a lost packet is detected;decoding the array of data packets column by column using an erasure decoding algorithm for said decoder of said Forward Error Correction Coding scheme; anddiscarding, if no errors occur, said at least two code word packets for each column that fails to contain lost packets. 2. The method of Packet Forward Error Correction Coding of claim 1 wherein said step of encoding comprises: encoding each column of said array of data packets using a systematic Maximum Distance Separable code. 3. The method of Packet Forward Error Correction Coding of claim 1 wherein said step of encoding comprises: encoding each column of said array of data packets using a systematic Maximum Distance Separable code. 4. The method of Packet Forward Error Correction Coding of claim 3 further comprising: subdividing said received array of data packets at said destination into a plurality of frames;representing a lost packet by a row of erasure symbols; andrecovering the erased symbols in each received frame which contains only one lost packet using erasure decoding for the single parity check code. 5. The method of Packet Forward Error Correction Coding of claim 4 further comprising: removing, if there are still rows of erasure symbols in the received frames, the rows of parity-check erasures in each received frame; anddecoding the array of data packets column by column using the erasure decoding algorithm of the Maximum Distance Separable code. 6. The method of Packet Forward Error Correction Coding of claim 1 wherein said step of encoding each column comprises: encoding each column of said array of said plurality of sequential frames and appended parity frame using a systematic Maximum Distance Separable code. 7. The method of Packet Forward Error Correction Coding of claim 1 further comprising: recovering lost packets in each of said plurality of sequential frames of data packets received at said destination using said at least two codeword packets. 8. The method of Packet Forward Error Correction Coding of claim 7 further comprising: recovering remaining lost packets in each of the rows of all of said plurality of sequential frames using said single parity packet for each row of said plurality of sequential frames. 9. The method of Packet Forward Error Correction Coding of claim 1 wherein said step of preprocessing comprises: processing each of said plurality of frames with a linear block code to generate a single parity check symbol for each row of said plurality of sequential frames.
