| Abstract | Due to the high compression ratio of MPEG-2 video codec, the terrestrial transmission of high definition television (HDTV) has received a lot of attention. In the Grand Alliance HDTV system, the HDTV video is compressed by MPEG-2 video code and protected by Reed-Solomon code and Trellis code from channel errors when it is transmitted over the 6 MHz channel. In this thesis, the newest H.264 video code, which has achieved a significant improvement relative existing video code, and the robust Turbo channel code are proposed to l;>e used instead of MPEG-2 video code and Trellis code respectively. The modulation and OFDM method of the Grand Alliance are not considered. The QPSK modulation method is used in the simulation model. The outperformance of Turbo code over Trellis code is observed by investigating the simulation results of the two channel codes. The comparative investigation of the two video codes shows that the efficiency of the rate saving of H.264 video is about 50 % better than that of MPEG-2 within a less than 20 Mbit/s bit rate region. The main objective of this study is to investigate the performance of the proposed HDTV transmission model using different channel coding schemes over Rician fading channel. Two EEP schemes and three UEP schemes are proposed to be used. According to the simulation results, the performance in terms of SNR of each EEP and UEP schemes depends on their code rate. The strongest scheme gives the best performance in expense of using more parity bits by reducing the data rate for video, which needs a higher data rate for higher quality. Between EEP and UEP schemes, the simulation results show that the performance of UEP3 scheme is superior to the performance of EEP2 schemes even though their average code rates are not much different. |
