Abstract: A method for receiving an HTTP adaptive streaming video from a server, said method comprising at a client, operatively connected to said server upon receiving a chunk of said video, determining a current rate of transmission for transmissions from said server to said client; obtaining statistical information pertaining to an expected future rate of transmission, in function of at least said current rate of transmission; deriving a target rate of transmission from said statistical information; and requesting a subsequent chunk of said video in accordance with said target rate of transmission.

Abstract: For adaptive streaming, a video item is available in plural quality versions. Corresponding video slices (411, 421; 412, 422) in the different quality versions are pre-processed to contain bit strings for equal image portions. The client (303) can request a video segment of the video item thereby specifying in its request any arbitrary requested quality/bit rate. An adaptive streaming aware node (301) thereupon selects video slices/NAL units (431, 442) for the requested video segment proportionally from plural quality versions in a ratio matching the arbitrary requested quality. The adaptive streaming aware node (301) streams the video segment composed of the proportionally selected video slices/NAL units (431, 442) to the client (303).

Abstract: A content delivery architecture comprises an intermediate domain via which content is transferable from content providers in at least one content provider domain to consumers in at least one consumer domain. A delivery layer is included having a content store in the intermediate domain for storing content from content providers in the at least one content provider domain for delivery to a consumer. A discovery layer has a content metadata store in the intermediate domain for storing metadata associated with content available from the content store and from content providers in the at least one content provider domain. A support and service layer administers the delivery of content from the content store, and from content providers in the at least one content provider domain, to a consumer using metadata stored in the content metadata store.

Abstract: The present invention relates to a method for providing peer-to-peer emergency service in a peer-to-peer network. The method comprises receiving a peer-to-peer emergency request (2). Said request (2) comprises an identifier relating to the origin (110) of the request (2). The identifier is used to identify the network access provider at the origin (110) of the request (2). The location of the origin (110) of the request (2) is retrieved from said network access provider (150). The invention also relates to a emergency service peer (100) for providing peer-to-peer emergency service.

Abstract: A method for use in a Generic Packet Radio System backbone network to transport an internet packet destined to a terminal from a gateway support node via a serving support node to a radio network controller. The method comprises for the downstream transportation the steps of: transforming the header into a backbone header; inserting in the backbone header an address of the serving support node and of the radio network controller; forwarding the internet packet after each insertion step to the radio network controller; and keeping track of the address of the terminal during the forwarding by use of an address extension header and by operations on the address extension header during and after forwarding. The upstream transportation is executed in the opposite direction, whereby steps executed during downstream transportation by the gateway support node are now executed during upstream transportation by the radio network controller and vice versa.

Abstract: A data cell generator multiplexes a plurality of data/speech packets (P1, P2, P3) into a single minicell (MC1′), for instance an Asynchronous Transfer Mode Adaptation Layer minicell, and adds overhead information (OH) to the minicell (MC1′) indicative for the lengths of the data/speech packets (P1, P2, P3) multiplexed therein. Several minicells (MC1′, MC2′, MC3′, MC4′) thereafter are multiplexed into a data cell (ATM_C), for instance an Asynchronous Transfer Mode) cell.
