Abstract
In this paper, we propose a new algorithm for generating test bit-stream in high quality to evaluate the static image quality of DTV receiver, based on a target bit allocation in the process of rate control. In order to allocate the number of target bits, we consider the normalized complexities, which are updated or maintained according to GOP picture qualities. The proposed rate control method is suitable for the compression of static test pattern while MPEG-2 Test Model 5 is suitable for moving picture. To evaluate the performance of proposed algorithm, the test bitstream are generated by a MPEG-2 software encoder using the proposed algorithm. Experimental results show that average PSNR of the proposed method is higher than those of the conventional case. With experiment in DTV system, we have confirmed that the proposed algorithm has a stable bit rate and good video quality and it is suitable for evaluation of the DTV receiver.
