Video Recommender: This kind of systems aim at retrieving users’ preference based on their past interactions, and recommend videos that can be of value for the Livepeer user.The semantic organzation of the event-related videos from different sources is essential to track and extract the most relevant of them, while maintaining an adequate degree of diversity. Topic Tracking: Broadcast video, especially news video, contains a broad range of real-world events that could be of critical value for the affected or interested persons. Video Monitoring: Being able to monitor the ways in which a video asset is used permits Livepeer creators and their sponsors measure the impact of it and, for instance, evaluate the repercussion of embedded commercials.Besides, this usually results in a huge risk for Livepeer platform to become liable for these behaviors. Copyright Protection: Digital products are highly sensitive to different forms of fraud, like unauthorized copying, editing and / or redistribution (see copy minting of NFTs, for example).This basically opens the door to several applications which are worth exploring. Recent developments included in the Livepeer Protocol (see MPEG-7 perceptual hashing) include the possibility of accessing an MPEG-7 perceptual hashed version of the transcoded videos. It is considered essential in a variety of applications that involve copy detection, copyright protection, video retrieval, indexing and management and video recommendation and search. Near-Duplicate Video Detection (NDVD) and Near-Duplicate Video Retrieval are hot research topics of increasing interest in recent years due to the exponential growth of online video creation.
