System and method for automatic categorization of audio/video content

Method for automatic categorization of content of an audio/video data stream, the method being characterized in that it comprises the steps of:

• accepting a request to execute said categorization of said content of an audio/video data stream;
• detecting a start and an end of at least one advertisements block present in said audio and/or video data stream;
• for each detected advertisements block:
• selectively collecting audio and/or video data frames, from said audio and/or video data stream, within specified time intervals prior to said detected advertisements block;
• for each time interval, for which audio and/or video data frames have been selectively collected, computing a fingerprint;
• selectively collecting reference audio and/or video data frames, after said advertisements block, for comparison and computing a reference fingerprint for said reference audio and/or video data frames;
• comparing said reference fingerprint with at least one fingerprint collected prior to the start of said advertisements block in order to obtain a level of similarity between said fingerprints;
• based on the level of similarity, taking a decision whether to indicate a split point between distinct content items present in said audio/video data stream.
