Abstract: A system for resource provisioning for content delivery of multiple services is disclosed. The system may be configured to offer multiple services, wherein at least one first offered service is delivery of prerecorded content and at least one second offered service is content delivered according to a deadline. In at least one embodiment, the first offered service may be video content, and the second offered service may be broadcast television content. The system may also be configured to deliver at least a portion of the first offered service in advance of use of that portion of the first offered service such that resource demand in connection with delivery of service content of the second offered service at peak delivery may be reduced. As such, fewer resources are needed to provide uninterrupted service of the first and second offered services.

Abstract: Aspects of the subject disclosure may include, for example, identifying FOV and OOS tiles of the video content. The FOV and OOS tiles are received from a video server. The FOV and OOS tiles are encoded using AVC and a first layer of SVC, respectively. Further embodiments include providing the FOV and OOS tiles for presentation on a display, detecting a change in a field of vision, and identifying other FOV tiles of the video content, which comprise a portion of the OOS tiles. Also, embodiments include requesting the portion of the OOS tiles and receiving the portion of the OOS tiles from the video server over the communication network, which are encoded using an enhancement layer of SVC and then provided, to the display, according the enhancement layer in conjunction with the providing of the OOS tiles according to the first layer. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, identifying a field of view (FoV) within a first frame of a video that occupies a sub-portion of the frame. A size is determined by subdividing a portion of the video according to a tiling scenario. Tiles overlapping the FoV are detected, and an updated size is determined based on an encoded version of the tiles and compared to a reference size. Responsive to the updated size being less than the reference size, the reference size is adjusted to the updated size, the tiling scenario is adjusted according to an adjusted tiling scenario, and the determining of the size is repeated based on the adjusted tiling scenario. Responsive to the updated size not being less than the reference size, a preferred tiling scenario is identified based on the adjusted tiling scenario for tiling the video. Other embodiments are disclosed.

Abstract: A system that incorporates teachings of the present disclosure may include, for example, initializing a boundary estimate for an optimization of a linear programming model describing a network of media servers for servicing requests for media content items from subscriber devices, where the boundary estimate is an estimate of an infeasible solution of the linear programming model, and calculating iteratively, using an exponential potential function, additional boundary estimates for the linear programming model, wherein the calculating resolves to an improved boundary estimate that corresponds to placement of copies of the media content items at the media servers subject to a set of constraints on storage capacity of media servers and on bandwidth for communication links in the network. Other embodiments are disclosed.

Abstract: A processor performing functions of a video client may measure an occupancy of a video buffer, select a video chunk having a first video encoding bitrate based upon the occupancy, and provide a deadline for a delivery of the video chunk to a multipath transport layer module. The processor may further activate a deadline aware scheduler of the module when the occupancy exceeds a first threshold and when the deadline aware scheduler was previously disabled, and deactivate the deadline aware scheduler when the occupancy falls below a second threshold and when the deadline aware scheduler was previously enabled. The module may request packets of the video chunk from a video server and select at least one active interface for the video server to send each packet. The deadline aware scheduler may select whether a secondary network interface is to be an active interface or a non-active interface.

Abstract: A content monitor includes a processor that at least receives requests from a plurality of clients for content, instructs each client to retry their respective request at a first later time if the request is received before a first time, counts the requests to determine if a number of the requests exceeds a threshold if the request is received before a second time, instructs each client to retry their respective request at a second later time if the counted number of requests does not exceed a first threshold, instructs each client to join a multicast group to receive the content when the number of requests exceeds the first threshold, and counts a number of late clients joining the multicast group after a first portion of the content has been sent to the multicast group.
