The invention provides an embedded probe video traffic and quality converging analysis method and device of a set top box. The method includes that set top box embedded software is utilized to regularly water video content for traffic packet capturing; the set top box embedded software analyzes packet capturing data; the set top box embedded software regularly reports data to a management system server; the data from the set top box embedded software are cleaned, and converging is performed according to network dimensionality data on the basis of Internet TV business networking topology and according to geographic dimensionality data on the basis of geographic position of a user of the set top box; a video playing quality index of the set top box is recorded, whether the video playing quality index exceeds a preset threshold index or not is judged, a fault event is recorded and stored in a database if yes, and an active dial testing task is issued to confirm whether a fault appears ornot. On the basis of a correlation analysis method of behavior data of the user of the set top box and data of the active dial testing task, convenience is brought to fault handling and quality evaluating of the set top box.
