A video server comprises memory to store video content obtained from multiple camera views; one or more streaming components configured to stream video content to a client application; and one or more frame feeder components. A frame feeder component is configured to access first video content corresponding to a first camera view and provide the first video content to a streaming component; access, in response to a request received at the video server to stream second video content corresponding to a second camera view, intermediate video content corresponding to one or more camera views intermediate to the first and second camera views; and access the second video content, and provide the intermediate video content and the second intermediate video to the streaming component.

Multi-view video streaming with fast and smooth view switch

A QoS management scheme for SDN. Network resource availability of routers and switches are maintained in a central resource database of a SDN controller. The SDN controller performs resource reservation, admission control and route calculation. When a flow is admitted or completed, the resource database is updated accordingly. Dynamic queue mapping for QoS routing in SDN is also provided. For a traffic flow with a certain traffic description and delay requirement, the queue mapping protocol dynamically assigns the flow to different priority queues at different switches along its routing path. Compared with the static mapping of a flow to a specified priority queue, the disclosed mapping is more flexible and uses network resources more efficiently.

Dynamic priority queue mapping for QoS routing in software defined networks

A method for scheduling user equipment (UE) devices comprising sorting the plurality of UE devices based on a weight of priority associated with each of the UE devices with respect to a plurality of subbands, and assigning one or more of the UE devices to each of the subbands using the weight of priority associated with the UE devices, wherein the weight of priority is based on one or more network utility functions associated with the UE devices. A computer program product comprising computer executable instructions to receive a media content segment using a dynamic adaptive video streaming over hypertext transfer protocol (HTTP) (DASH) protocol, monitor a playback buffer size of a UE device, monitor a battery energy level of the UE device, and adjust a representation quality level in a segment request based on the target requested video rate, the playback buffer size and the battery energy level.

Method, device and apparatus for delivering video telephony by using a media controller and a software defined networking (SDN) controller to enable multicasting for multi-party video conferencing. A media controller generates a video sending rate for each of the plurality of client devices based on a received video conference request and received network information. The media controller determines and independently constructs a maximum-rate delay-bounded multicast tree for each of the plurality of client devices that supports the largest possible multicast rate. The media controller determines a common congested link in the multicast trees, re-routes the multicast tree with the common congested link for the client device with the lowest weight of utility divided by its video sending rate and creating two subtrees, and iteratively re-routes the multicast trees until an aggregate video sending rate of the multicast trees sharing the common congested link meets a link capacity of the common congested link.

System and methods for connection pooling for video streaming in content delivery networks (CSNs) are provided. An embodiment method for connection pooling in a content delivery network (CDN) by a proxy server includes receiving, from a client, a request for media content, sending, to a control server, a query to locate an origin media server having the media content if the media content is cache-missing, receiving, from the control server, information regarding the origin media server having the media content requested by the client, and forwarding the request for the media content to the origin media server having the media content using a reusable connection from a pool of the reusable connections between the proxy server and the origin media server if the reusable connection is unoccupied.
