  • Patent number: 11218529
    Abstract: Systems and methods of controlling transmissions of a media stream are provided. In one exemplary embodiment, a method performed by a media client for controlling a transmission of a media stream from a media server to the media client may include obtaining a media description of the media stream. The media description may indicate an initial stream element of the consecutive stream elements. Further, the method may include sending a request for the initial stream element. In addition, the method may include requesting, towards a control entity for a session, an establishment of the session or a modification of the session, for associating the media stream with the session. After sending the request for the initial stream element, the method may include receiving a result of the session establishment or session modification request.

  • Patent number: 9215084
    Abstract: The invention relates to a method for generating a personalized content file for a user entity using a file repair request for identifying a user. The file repair request is initiated by generating a preliminary file that is transmitted to the user entity, the preliminary file containing a predetermined placeholder. The preliminary file is transmitted to the user entity, the user entity starting the file repair request. The personalized content file is generated by replacing the predetermined placeholder in the preliminary file by a personalized content.

  • Patent number: 8769300
    Abstract: A technique for content management using group rights is described. The technique facilitates a flexible management for a group of content files mainly by effecting a change of group memberships for subsets of the group and a partial update of the content files. As one aspect, a content file manager (20) is provided to create content files associated with group rights. A device (21) is also provided to process such content files. One method aspect comprises assigning a plurality of content items to a new group whose identifier is associated with a new group rights object; determining if any of the content items has been previously distributed; and for each previously-distributed content item, creating an update content file including the group identifier of the new group and excluding the previously-distributed content item itself.
