Cache management techniques are described for a content distribution network (CDN), for example, a video on demand (VOD) system supporting user requests and delivery of video content. A preferred cache size may be calculated for one or more cache devices in the CDN, for example, based on a maximum cache memory size, a bandwidth availability associated with the CDN, and a title dispersion calculation determined by the user requests within the CDN. After establishing the cache with a set of assets (e.g., video content), an asset replacement algorithm may be executed at one or more cache devices in the CDN. When a determination is made that a new asset should be added to a full cache, a multi-factor comparative analysis may be performed on the assets currently residing in the cache, comparing the popularity and size of assets and combinations of assets, along with other factors to determine which assets should be replaced in the cache device.

In an example implementation, a method is described. The implementation accesses a plurality of media clips including a first video clip and a second video clip, matches a first fingerprint of the first video clip with a second fingerprint of the second video clip. The implementation also matches a first event subject of the first video clip with a second event subject of the second video clip, and determines an overlap of the first video clip with the second video clip based at least in part on the match of the first fingerprint with the second fingerprint and the match of the first event subject with the second event subject. The implementation also merges the first video clip and the second video clip into a group of overlapping video clips based on the overlap, and synthesizes the group into a video presentation.

In an example implementation, a method is described. The implementation accesses a plurality of media clips including a first video clip and a second video clip, matches a first fingerprint of the first video clip with a second fingerprint of the second video clip. The implementation also matches a first event location of the first video clip with a second event location of the second video clip, determines an overlap of the first video clip with the second video clip based at least in part on the match of the first fingerprint with the second fingerprint and the match of the first event location with the second event location, merges the first and second video clips into a group of overlapping video clips based on the overlap, and generates a presentation that includes the group formed by merging the first and second video clips based on the overlap.

Systems and methods may be provided for retrieving non-on-demand media data and on-demand media data that is provided by separate data sources. On-demand media data may be cached to reduce system latencies and the burden on the distribution network.

A system for presenting live video content to a plurality of participant client devices is disclosed. An interactive program, including the live video content and an interactive component, is generated and a moderator interface is provided to enable a user of a moderator client device to create a look for the interactive program. The live video content and the interactive component are simultaneously displayed on a display of each of a plurality of participant client devices with the look created by the user of the moderator client device. The live video content and a response to the live video content are simultaneously displayed at each of the participant client devices with the look created by the user of the moderator client. The interactive program and the response are archived so that users of the plurality of participant devices may continue to interact with the interactive program after termination of the interactive program.

In an example implementation, a method is described. The implementation accesses a plurality of media clips including a first video clip and a second video clip. The implementation also matches a first fingerprint of at least a part of the first video clip with a second fingerprint of at least a part of the second video clip. The implementation also determines a temporal overlap of the first video clip with the second video clip based at least in part on the match. The implementation also, based on the temporal overlap of the first video clip with the second video clip, merges the first video clip and the second video clip into a group of overlapping video clips, and transmits, to a client computing device, data identifying the group of overlapping video clips and specifying a synchronization of the first video clip with the second video clip.

A resource management system may use information regarding the bandwidth status of a downstream communication path to determine what portion of queued content should be sent in the current available bandwidth timeslot. In some embodiments, multiple versions of the same requested content may be available, and the system may select a lower-quality version to send if needed to meet a time deadline included in the original content request.

In an example implementation, a method is described. The implementation accesses a plurality of media clips and metadata for the plurality of media clips. The implementation also uses the metadata for the plurality of media clips to select, from the plurality of media clips, a subset of media clips including a first media clip and a second media clip. The implementation also matches a first fingerprint of at least a part of the first media clip with a second fingerprint of at least a part of the second media clip. The implementation also determines a temporal overlap of the first media clip with the second media clip based at least in part on the match. The implementation also, based on the temporal overlap, merges the first media clip and the second media clip into a group of overlapping media clips, and generates a presentation that includes the group.

In an example implementation, a method is described. The implementation accesses first and second media clips. The implementation also matches a first fingerprint of the first media clip with a second fingerprint of the second media clip and determines an overlap of the first media clip with the second media clip. The implementation also, based on the overlap, merges the first and second media clips into a group of overlapping media clips, transmits, to a client device, data identifying the group of overlapping media clips and specifying a synchronization of the first media clip with the second media clip, and generates for display on a display device of the client computing device, a graphical user interface that identifies the group of overlapping media clips, specifies the synchronization of the first media clip with the second media clip, and allows access to, and manipulation of, the first and second media clips.

Systems and methods for providing guidance to users for finding media are described. Such systems and methods may be provided in interactive media guides such as program guides, web browsers, or other suitable interactive media guides.
