A technology for content delivery is provided. In one example, performance of a caching network, performance of a delivery network, and customer demand are modeled. Instructions are provided for a client device on how to request content based on the modeled performance of the caching network, the modeled performance of the delivery network or the modeled customer demand.

Methods and systems may be used by a mobile-content distribution network (CDN) service to track individual user requests based on a correlation of a network level identifier to an application level identifier. The users may also be tracked using a mapping of the network level and application level identifiers to an internal identity. Further, the mobile-CDN service may build a cell profile using content requests from a set of active users across similar locations. Also, the mobile-CDN service may build a cell profile using content requests from user groups that have at least one member as an active user of the cell. Using a cell profile, the mobile-CDN may generate a prefetching content list for managed caching in the cell by localizing the content popularities and viewing patterns. The methods and systems may be applied in a small cell network (SCN).

A device, system, and method synthesizes personalized linear television experiences from on-demand assets, live event video, streaming graphics, and dynamic ad insertion, where portions of the broadcast day are scheduled for globally shared viewing events, where other portions are scheduled for distinct programming for various audience segments. Vector graphics are streamed independently of the video and rasterized locally to improve quality and contextualization of the graphics layer while gaining the efficiency of leveraging the same cached video assets for linear and on-demand applications. The system includes origination services transforming and publishing linear television schedules, video, and graphics to a distribution cache, a live event server streaming live performances, an advertising server providing targeted advertising, a personalization server, and assembly services stitching the elements to create a continuous experience of video and graphics for a media player to receive and render for each channel selected by the viewer.

A computing device may include a memory and a processor cooperating therewith to receive a plurality of data streams from at least one data source to be relayed to different destinations on demand, where each data stream has a respective content identifier associated therewith. The processor may further determine when a first one of the data streams for a first destination shares identical data with a second one of the data streams for a second destination based upon the respective content identifiers associated therewith, and suspend relaying the second data stream to the second destination, and begin relaying the first data stream to the second destination, based upon the determination that the first and second data streams share identical data based upon the respective content identifiers associated therewith.

Systems, devices, and methods for streaming or otherwise delivering media content over a network are provided. One exemplary method of streaming media content over a network using a RS-DVR system involves receiving, at the RS-DVR system, a request for a portion of the media content from a media player on a client device via the network, receiving, at the RS-DVR system, the portion of the media content from an origin server on the network, buffering the portion of the media content at the RS-DVR system, and transmitting the portion of the media content to the media player on the client device. The portion of media content may be transmitted using a modified transport layer protocol, and in some embodiments, marked as non-cacheable.

Content delivery is provided responsive to mediacast content consumer requests by providing personalized mediacasts to each of a plurality of mediacast content consumers. Each of the personalized mediacasts includes a variety of replaceable programming and non-programming content segments and a variety of non-replaceable programming and non-programming content segments. Replacement programming and non-programming content segments may be targeted, for example selected based in part on one or more selection criterion associated with the mediacast content consumer, or provided by the broadcaster or Webcaster. A buffering scheme may be employed to inherently adjust asynchronicity between a broadcast or Webcast and a personalized mediacast. Actual insertion of replacement programming and non-programming content segments may occur upstream of a content consumer device or at the content consumer device.

A content delivery service includes a management service for determining an anticipated window of time in which supplemental content can be inserted in the dynamic content stream. The management service will then pre-fetch supplemental content from the third party supplemental content service prior the identification or request for supplemental content to be included in the streaming content. During the streaming of content to individual users via an established channel, as markers for insertion opportunities are identified, the content delivery service will attempt to utilize the pool of pre-fetched supplemental content.

Transaction activity of a cache maintaining content may be monitored to determine periods of transaction activity below a first threshold amount of transactions. A period of anticipated transaction activity above a second threshold amount of transactions may be determined. A period of anticipated transaction activity below the first threshold may be selected based upon the monitored periods of transaction activity below the first threshold and the determined period of anticipated transaction activity above the second threshold. Content then may be evicted from the cache during the selected period of anticipated transaction activity.

Implementations provide low-latency live-video streams using existing content delivery networks. An example method includes receiving a video broadcast as a series of frames and determining, for each frame, whether the frame is a break frame. Responsive to determining that the frame is a break frame, the method includes removing an in-progress tag from a current segment file in a playlist for the video broadcast. The playlist includes at least a previous segment file, the current segment file, and a next segment file, which also has a respective in-progress tag. The method also includes associating the frame with a next segment file in a playlist and transmitting the playlist to a cache server. Responsive to determining the frame in the series of frames is not a break frame, the method includes associating the frame with the current segment file. The frame is transmitted to the cache server as a chunk.

A system and method is presented that segregates portions of a video file into distinct sections based on whether the sections contain original content or modified content. For each segment, portion, section or scene with modified content, a compressed file is created which includes at least one instance of a set of frames which includes modified content. For some sections there may be two or more versions of modifications. These alternative versions may be compressed as a single distinct file. This permits efficient edge caching of video files with modified content, for example for selective provision of alternative versions of the video file to various end users in a transmission efficient manner.
