| Abstract: |
An error protection method for multimedia improves data recovery and channel throughput in channels which cause a random error and a burst error by using a rate compatible punctured convolutional code (RCPC) and an automatic retransmission on request (ARQ). In a process of decoding a plurality of packets of given information, the error protection method includes the steps of a) decoding one of the plurality of packets, b) decoding another packet when an error occurs during the decoding in step a), c) decoding a combination of the packets from steps a) and b) or a third packet when an error occurs in step b), and d) repeating step c) until the decoding error no longer occurs. The error protection method has the characteristics of both Type-1 and Type-2 ARQ methods. Therefore, one can obtain constant channel throughput in a channel containing burst errors, a channel containing random errors, and a channel in which the two types of error patterns coexist simultaneously.

What is claimed is:
1. A method of protecting errors from occurring during decoding of a plurality of packets of given information, comprising the steps of:
- a) decoding one of said plurality of packets;
- b) decoding another packet when an error occurs during said decoding in said step a);
- c) decoding a combination of said packets of said steps a) and b) or a third packet when an error occurs during said decoding in said step b); and
- d) repeating said step c) until no decoding error occurs.
