A carrier synchronizer with an adaptive loop bandwidth for rapid carrier frequency offset acquisition and low steady-state jitter is proposed. The new carrier recovery loop consists of a tracking-status detector and a loop bandwidth controller. The tracking-status detector monitors the frequency-estimate signal output from the loop filter, determining whether the residual carrier frequency offset is locked or not. Then, by adjusting the loop bandwidth, it can reduce the convergence time of the acquisition-state and carrier jitter of the steady state. The new scheme, implemented by FPGAs, has been successfully applied to a 256-QAM baseband digital receiver and inter-operated with commercial CMTSs. Only around 11200 gates are needed for the new carrier synchronizer; however, the SNR can be improved by up to 3 dB.","PeriodicalId":319221,"journal":{"name":"2003 IEEE International Conference on Consumer Electronics, 2003.

Also, it does not significantly increase computational complexity since it uses the estimated motion vectors and the sum of absolute difference (SAD) previously obtained from the conventional ME.

The ROIs are automatically selected by a robust skin-color detection which utilizes the Cr and RGB variance instead of the traditional skin color models, such as YCbCr, HSI, etc. The skin color model defined by Cr and RGB variance can choose the skin color region more accurately than other methods. For the video coding system, a region-based video codec based on H.263+ with the option mode of modified quantization is set up. We adjust the distortion weight parameter and variance at the macroblock layer to control the qualities at different regions. Experimental results show that the proposed method can significantly improve the quality at the ROI. Our method is suitable for real time videoconferencing.","PeriodicalId":319221,"journal":{"name":"2003 IEEE International Conference on Consumer Electronics, 2003.
