EDGE SERVER FOR THE DISTRIBUTION OF VIDEO CONTENT AVAILABLE IN MULTIPLE REPRESENTATIONS WITH ENHANCED OPEN-GOP TRANSCODING

摘要

The invention relates to a video server comprising: an input port configured to receive from a user terminal requests to deliver video segments, each video segment in a target representation; an output port configured to deliver the requested video segments to the user terminal; a data link configured to retrieve from storage capabilities, for each request from the user terminal a video segment in at least one source representation in an Open GOP scheme; an access to one or more video transcoding capabilities; said video server being configured to cause said one or more video transcoding capabilities to transcode at least a part of the video segment in said at least one source representation in an Open GOP scheme into the requested target representation in a Closed GOP scheme, when the requested target representation is different from a representation previously provided to the user terminal. It also relates to the corresponding user terminal, method, and computer program.
