摘要：
In this paper, a non-intrusive approach for measuring Audio/Video (AV) synchronization delay for wide range of multimedia devices is presented. The approach combines QR codes and sweep markers to enable cost-effective AV delay measurement in real-time. The concept relies on transmission of reference signal from source to the end-device and rendering on it. The output of the end-device is captured with any available camera. The audio/video delay is extracted from the captured content. The complexity of the measurement process allows execution in real-time on embedded platforms. It is also tolerant to occasional losses and degradations in the signal.
