摘要：

In this article, we propose a simple method to monitor the end-to-end live lag in a way which is scalable and meaningful for the service providers. The proposal is based on detecting the wall-clock timestamp of the video frames at capture time and inserting it in-band, so that it is available at any point in the network. Live lag can be monitored at any point of the chain, with the same accuracy as the one provided by the clock synchronization mechanism used.
