A method for estimating bandwidth between a video server and a video client for playing back a video stream includes video packets. The method involves the following steps performed by the video client: receiving the video packets from the video server wherein the video packets are transmitted by the video server at predetermined time intervals; calculating a difference in a size of the video packets and a difference in a time of reception of the video packets; and estimating the bandwidth based on the calculated difference in size and the calculated difference in the time of reception. The present disclosure further relates to a media player configured to perform the disclosed method.
