摘要： The invention involves collective management of video (30) and audio (40) content in a content provider (100). The video (30) and audio (40) content is available in multiple potential versions (32, 34, 36; 42, 44, 46), e.g. in the form of scalable media (36, 46) or media (32, 34; 42, 44) pre-encoded to fixed bandwidth levels. The video (30) and audio (40) data is associated with bandwidth share information (62, 64, 66) enabling estimation of a respective apportionment of a total available bandwidth to the video (30) and audio (40) content. The provider (100) uses this share information (62, 64, 66) and information of the total assignable bandwidth level for providing a respective video version (32, 34, 36) and audio version (42, 44, 46) from the multiple potential versions (32, 34, 36, 42, 44, 46). This allows for increased user-quality when rendering the video (30) and audio (40) data as optimal video (32, 34, 36) and audio (42, 44, 46) version can be dynamically provided during the media session.

摘要： A network processing node (e.g., MGW, MRFP) and method are described herein that can: (1) receive packets on a first heterogeneous link (e.g., wireless link); (2) manipulate the received packets based on known characteristics about a second heterogeneous link (e.g., "Internet" link); and (3) send the manipulated packets on the second heterogeneous link (e.g., "Internet" link). For example, the network processing node can manipulate the received packets by adding redundancy, removing redundancy, frame aggregating (re-packetizing), recovering lost packets and/or re-transmitting packets.
