We tackle the problem of burst error in wireless video transmission. Burst error damages video information so severely that it is very difficult to restore the lost information. For restoration, it is advantageous to retain a part of block information. To achieve this, we propose a coefficient sampling and interleaving method, where texture coefficients are grouped into several coefficient groups (CG) so that the groups have equal importance. The CGs are interleaved so that burst error cannot damage all CGs from one block. A restoration method is proposed to utilize the retained coefficients. The simulation results show that the proposed coefficient sampling scheme and the restoration method restore the lost information very well.
