Abstract :
Lossless data compression, such as arithmetic coding and Ziv-Lempel coding, is widely used for text compression. Since errors in compressed data have a great influence on the decompression, error control for the compressed data is necessary. From this view point, the authors propose a burst error recovery method in arithmetic coding. They consider error recovery schemes for LZW coding and LZ77 coding by using unequal error protection (UEP) schemes, which protect the important parts of the compressed data more strongly
