The present invention discloses an IP video real time monitoring method and system, and is mainly used for verifying and controlling the content transmitted by Internet videos. The method specifically includes: performing pre-extraction of features of a video file and storing the video file into a feature library; obtaining and pushing, by a system tandem connection front end, sample video data to a video feature comparison unit through Internet lines thereof using rough feature matching; comparing, by the video feature comparison unit, the sample video data with a female parent feature in the video feature library after protocol reassembling and feature extraction, and notifying a management unit the result in combination with video flow information; generating, by the management unit, exact feature configuration information for the video data flow based on a combination of a user processing strategy and thecomparison result, and feeding back the exact feature configuration information to the tandem connection front end unit, thereby accomplishing on-line processing of actual Internet video flow. The present invention uses the method of extracting the content feature of the video combined with the means of tandem connection management of the Internet lines, to achieve real time line speed control of the content level transmitted by the Internet videos.
