A method, medium, and apparatus are disclosed for indexing multimedia content by a computer. The method comprises segmenting the multimedia content into a plurality of segments. For each segment, the method identifies one or more features present in the segment, wherein the features are of respective media types. The method then identifies, for each identified feature in each segment, one or more respective keywords associated the identified feature. Then, the method determines, for each identified keyword associated with an identified feature in a given segment, a respective relevance of the keyword to the given segment. The respective relevance is dependent on a weight associated with the respective media type of the identified feature.

Apparatus and methods for indexing multimedia content

A method and client device is disclosed for indexing content of a multimedia file. The method comprises using a client device to segment the content of the multimedia file into a plurality of segments and to determine structure-searchable data for each segment. Determining structure searchable data for a segment comprises (1) identifying one or more features of respective multimedia types in the segment; (2) correlating each of the identified features to one or more respective keywords; and (3) calculating one or more respective relevance factors for each of the keywords, where at least one of the relevance factors is based on one or more characteristics of the client device. The method also comprises the client device transmitting the structure-searchable data (including the keywords, relevance factors, and respective media types of the identified features) to an indexing server.

Apparatus and methods for user generated content indexing

The present relates to a method and arrangement for controlling streams of participants of a virtual meeting, wherein at least a first participant and a second participant are located in a first location and at least a third participant is located in a second location. The arrangement comprises means for receiving location information associated with identity information for each participant, means for receiving a stream from each participant whereby the stream comprises at least audio and an identity of the respective participant, means for controlling transmission of each received stream separately to said participants based on said location information and identity information such that streams between the participants in the same location are blocked.
