Abstract: The invention concerns a device (D) for assigning time information to a main multimedia content related to a given object. To this end, said device comprises: a clustering module (4) configured to cluster a set of auxiliary multimedia contents with time information and related to said object, so as to deliver clusters comprising some of said auxiliary multimedia contents; a determining module (5) configured to determine a time data for each cluster; a computing module (6) configured to compute a distance between the main multimedia content and each of said clusters, an assigning module (7) configured to assign to the main multimedia content, the time data of the cluster having the smallest distance said amongst computed distances.

Abstract: According to the invention, the method comprises the following steps of: clustering said plurality of creators to deliver clusters comprising at least two creators, called relevant creators; assigning, to at least some relevant creators of the cluster comprising the first creator, called first cluster, a score of relevance determined from at least one criterion of similarity between said relevant creators and said first creator; ranking relevant creators of said first cluster according to their scores of relevance; selecting, among a plurality of multimedia contents, at least one second multimedia content related to said first multimedia content and delivered by a ranked relevant creator of said first cluster; enriching said first multimedia content based on said second multimedia content.

Abstract: A transmission method in a video apparatus connected to a database system of visual entities is disclosed. The method comprises: selecting a first visual entity in the video content; selecting a second visual entity in the video content; transmitting to the database system at least one information relative to an association of the first visual entity with the second visual entity. A receiving method in a database system of visual entities associated with metadata, the database system being connected to a video apparatus, is also disclosed.

Abstract: The invention concerns a method for enriching a multimedia content defined by a timeline and by a chronological text description, wherein it comprises the following steps of: identifying using natural language processing at least one feature in at least a part of a text document retrieved from a network, automatically aligning said determined part of the text document to at least a part of the chronological text description, which semantically corresponds to said determined part of the text document, so that at least the part of the text document is automatically synchronized with the timeline of the multimedia content, the chronological text description being itself synchronized with the timeline.
