Presentation timestamp (PTS) is a number indicating the moment when an elementary stream unit (video/audio/DVB subtitles) should be played. It is one of the most important parameters that determines if the video plays correctly. According to ETSI TR 101 290, the PTS repetition period should be no longer than 700 ms. Otherwise, the error of 2 priority is registered. 

Stream Analyzer allows you to easily validate the stream against the standard. The TR101-290 panel shows the present errors.
