Abstract
According to one or more embodiments, a playback device is provided. The device includes processing circuitry configured to receive a video stream including a plurality of video packets, where each of the plurality of video packets is associated with a respective video timestamp value. The playback device is further configured to store at least one of the plurality of video packets in a jitter buffer, and to adjust each of the respective video timestamp values by a respective delay value, where each of the respective delay values is either a dynamic delay value based on a first condition being satisfied or a fixed delay value based on a second condition being satisfied. The playback device is further configured to play the video stream according to the adjusted video timestamp values for reduced initial delay at the jitter buffer.
