Abstract:	In this paper, a new progressive image transmission (PIT) method is proposed. It is called the side-match reconstruction method using TSVQ (SMTSVQ). The proposed method is basically an improvement version of TSVQ. In order to take full advantage of the high correlation between adjacent pixels, half of the image blocks are transmitted interleavedly in each phase, and each block sends two bits. As for the receiver, a reconstruction method of side match technique is proposed to rebuild the unreceived blocks. From the experimental results, we see that the image quality of our method is better than those of the other previous works: SPITM, FRM and TSVQ. Especially at the first phase, the difference of PSNR between SMTSVQ and TSVQ is more than 3.7dB. Besides, the reconstruction time of SMTVQ is much less than that of SPITM and is very close to those of FRM and TSVQ. SMTSVQ is therefore efficient and effective in PIT.
