Abstract
Provided are a method and device for analyzing a data stream. According to the method, one of a plurality of sampling periods having a same sampling duration and different start times is allocated to an audio and video stream. A first arrival data packet of the audio and video stream within the allocated sampling period is copied as a first sample data packet based on a sample stream entry. A last arrival data packet of the audio and video stream within the allocated sampling period is copied as a second sample data packet. A sender delay and a receiver delay of the audio and video stream are calculated based on respective timestamps of the first and second sample data packets. A jitter of the audio and video stream is analyzed based on the sender delay and the receiver delay.
