Systems and methods of fingerprinting and identifying media contents

A method of identifying media contents comprising:

• a) extracting data from said media contents, said extracted data including encoded videos or audios, segments of videos or audios, image frames, audio waveforms and associated timestamps;
• b) generating a plurality of digital fingerprints from said extracted data of said media contents;
• c) processing said media contents including video or audio contents based on different segments, and extracting multiple fingerprints based on said segments with timestamps, or processing said media contents including video or audio contents based on different framerates, and extracting multiple fingerprints based on said framerates, wherein said segments are selected based on complexity of said media contents, and said framerates are determined based on resolution of said media contents;
• d) continuously executing fingerprint extraction and match operation before and during playing said media contents, and being able to real-timely conduct necessary processes based on match results;
• e) providing more accurate fingerprint matching results and necessary processes, based on timing of timestamps, including displaying detailed information or advertisement at specific time;
• replaying, muting or skipping specific segments;
• masking partial videos or audios;
• f) identifying said media contents by matching at least one of the calculated said digital fingerprints with corresponding said digital fingerprints of known media contents, supporting said different segments and said different framerates;
• and
• g) determining whether said media contents are copies of said known media contents as well as conducting said necessary processes based on match results.
