摘要
在MPEG-2标准的基础上,分析了PCR在数字电视传输系统中产生抖动的原因和校正的方法。同时在基于DMB-T的数字电视传输系统中用硬件实现了PCR校正单元,并通过对实际采集到的数据的分析,给出了PCR校正的效果。
Based on the standard of MPEG-2,the cause of PCR jitter and PCR correction method in Digital Television Transmission System are analyzed. The hardware implementation of PCR correction scheme in Digital Television Transmission System based on DMB-T is realized. Finally, the effect of PCR correction is given through analyzing the data collected in practical system.
