一种PCR抖动检测算法及实现

A Detection Algorithm and Implementation of PCR Jitter

在数字电视产品开发中,PCR抖动会导致终端音视频数据无法完全正确显示。给出一种基于有限状态机模型的PCR抖动检测算法及在Nucleus嵌入式实时操作系统下实现,该算法及实现在最新高端数字电视芯片上得到实际应用,具有较强的应用价值。

In the development of digital TV production, PCR jitter leads that audio and video data can＇t be fully shown by terminal device correctly. In this paper, a detection algorithm of PCR jitter based on finite state ma- chine model and an implementation under the embedded real time operation system nucleus are presented. The algorithm is applied to the high-end digital TV chip of Trident Multimedia Technologies Co. , Ltd. has a better practical application value for better quality of digital TV production.
