Abstract: A media server machine may be configured to provide media content within a datastream. This datastream may be provided to a media device that is configured to present the media content on a display. Also, this datastream may contemporaneously contain an “app-sync indicator” for the media content. The app-sync indicator is a data structure that signals the media device to launch an application on a companion device. By providing the app-sync indicator contemporaneously with the media content in the datastream, the launching of the application on the companion device may be synchronized with the media content. The app-sync indicator may specify the application to be launched. Also, the app-sync indicator may specify supplemental content to be presented by the launched application on the companion device.

Abstract: A method for initiating a call in a communications system comprising a mobile communications device connected in a mobile communications network. The mobile communications device is allocated a mobile identifier for a first, mobile communications service provided by a mobile communications service provider and is allocated a second identifier for a second communications service provided by a second communications service provider that is different from the first, mobile communications service. The method comprises receiving over a data connection, at a switch, a request from the mobile communications device, comprising the second identifier, to initiate a call using the second communications service and adding, at the switch, the mobile identifier to the request and forwarding via a further network, the request comprising both the second identifier and the mobile identifier.

Abstract: A method of selecting data, the method comprising, receiving data indicating a first requirement and identifying first records stored in a first database. The first records relate to first data subjects and the identification is based upon the first requirement. The first data subjects cannot be identified from the records of the first database. Second records are identified, the second records being stored in a second database and relating to the first data subjects. The first data subjects can be identified from the identified records of the second database. Each of the second records corresponds to a respective one of the first records, and the identification of the second records is based upon the first requirement.
