Abstract
Summary form only given. In DCT domain distributed video coding (DVC), the uniform symmetric scalar quantization has been widely implemented, where, coefficients organized into 16 DCT bands are quantized with the given quantization levels. For each sequence has its own contents, the optimal quantization levels should vary with frames. In this paper, a low complexity algorithm for designing adaptive quantization levels (AQL) according to the characteristic of the bands is proposed.
