Abstract

The presented invention proposes and evaluates an approach for Audio/Video (AV) synchronization delay measurement of multimedia content 100 caused by transmission channel and rendering approach at receiver side. The concept is based on synchronous insertion of audio and video markers 202, 203 into transmitted multimedia (reference) content at the sender side. For marking a video stream QR codes are used 202 and tones are used as audio markers 203. At the receiver side, after rendering by the receiver device, audio and video streams are captured synchronously using digital camera. The captured content 300 is analyzed and the audio/video delay is measured. Analysis and calculation of delay between audio and video 305 is done using interpolation with reference and measure audio / video time before and after rendering.
