一种高精度PTP 时钟同步方法及应用

A High Precision PTP Clock Synchronization Method and Its Application

PTP是实现网络精确时钟同步的热门技术之一,在工业以太网领域应用广泛。在IP流媒体传输领域,时钟同步至关重要。因此,介绍PTP时钟同步原理,提出一种时钟同步的具体实现方法,并将此方法应用于SMPTE ST 2110标准的SDI over IP技术,取得了满足产品实际应用的高精度时钟同步效果。

PTP is one of the most popular technologies to realize accurate clock synchronization in network,and it is widely used in the field of industrial Ethernet.In the field of IP streaming media transmission,clock synchronization is very important.This paper introduces the principle of PTP clock synchronization,and puts forward a specific implementation method of clock synchronization.This method is applied to the SDI over IP technology of SMPTE ST 2110 standard,and achieves the clock synchronization effect that meets the practical application of the product.
