Automated Replay Detection and Multi-Stream Synchronization

This paper introduces an algorithm for automated replay detection in CS:GO tournaments. Firstly, it uses a content-based approach for replay identification in the commentator stream and then the metadata to synchronize them to the player streams. The provided metadata for events cannot be used for detecting events in the streams, because the timestamps of these events are very inaccurate and differ up to 40 seconds. Furthermore, the algorithm uses a content-based approach along with the synchronization data to detect the equivalent scenes in the matching player stream.
