Abstract: A client selects a first quality level from a plurality of quality levels used to encode segments of video content for transmission over an air interface in a wireless communication system. The first quality level is selected based upon an indication of a location of the client and an indication of congestion in the wireless communication system. The client transmits a request for a first segment of the video content encoded at the first quality level.

Abstract: A capability for handling network connection changes during adaptive bitrate streaming is provided. A method includes receiving a request for a change associated with a network connection of a client device where the network connection of the client device is configured to support delivery of a content item to the client device using an adaptive bitrate streaming process of the client device, and delaying the change associated with the network connection of the client device based on a state of the adaptive bitrate streaming process. A method includes detecting that a chunk of a content item, requested by an adaptive bitrate streaming process of a client device via a network connection of the client device, has been received at the client device, and delaying a request for a next chunk of the content item based on a state of a change associated with the network connection of the client device.

Abstract: The present invention is related to a device for authorising access to data content protected by a control signal (CW) and delivered to a terminal over a network comprising an access network. The device is arranged for receiving a version of the control signal and further comprises processing means for processing the received version of the control signal and arranged for sending to the terminal an output signal derived from that processed version of the control signal. Said output signal enables the terminal to get access to the delivered data content protected by the control signal. The device is characterised in that it is operable in the access network.

Abstract: The invention includes a method and apparatus for facilitating distribution of content from content sources to content distributors. In one embodiment, a method includes receiving meta-data associated with a content item available from the content source and propagating a notification regarding availability of the content item from the content source, where the notification comprises at least a portion of the associated meta-data. The meta-data is received from a content source from which the content item is available. The notification message for the content item, including at least a portion of the meta-data is propagated toward a content distributor, thereby enabling the content distributor to obtain a copy of the content item for use in serving requests for the content item originating from end users served by the content distributor.
