Techniques for insertion of supplementary content into a segmented content stream are described. In at least some embodiments, a content stream includes primary content, such as streaming web content, a movie, an event broadcast (live and/or recorded), a television program, and so on. The content stream can be segmented, such as via techniques for adaptive bitrate streaming. Techniques discussed herein enable supplementary content, such as an advertisement, to be inserted into the content stream. The supplementary content can be inserted at any specified time point, even if the specified time point falls within a segment of the content stream. Techniques further enable playback of the content stream to be paused during playback of the supplementary content, and to resume after playback of the supplementary content.

Insertion of supplementary content into a segmented content stream

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for merging media stream indexes of a media stream are described in this specification. In one aspect, a method includes receiving a first media stream index at a first server system, including a first list of sequentially arranged fragment identifiers corresponding to at least a portion of multiple sequentially arranged fragments. Fragment identifiers that are potentially missing from the first index can be identified. A second media stream index including a second list of sequentially arranged fragment identifiers corresponding to at least a portion of the multiple sequentially arranged fragments can be requested from a second server system. The first and second list of the sequentially arranged fragment identifiers can be compared and the first list of sequentially arranged fragment identifiers can be reconstructed based on the comparison.

Media stream index merging

Exemplary embodiments involve a mediation application executed on a processor determining one or more digital programming insertion breaks in a linear media stream. The linear media stream can include electronic content delivered over a network at a time determined by the content provider. The mediation application can determine that a plurality of clients identified by a common group identifier and in communication with the mediation application are receiving the linear media stream. The mediation application can mediate a plurality of requests for digital programming insertion content provided by a digital programming insertion content provider by identifying digital programming insertion content targeted to the common group identifier. The mediation application can provide the digital programming insertion content during the one or more digital programming insertion breaks to the plurality of clients.

Mediating digital program insertion for linear streaming media

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for allocating server application logic across multiple tiers of a server system are described. In one aspect, a method includes hosting a server application on multiple servers. The servers include an application server deployed in a secure tier of an enterprise network and an edge server deployed in an edge tier of the enterprise network. A primary firewall isolates the secure tier from the edge tier and from a public network. A secondary firewall isolates the edge tier from the public network. The edge server is configured to receive requests for services provided by the server application, to perform a first subset of the services, and to relay a subset of the requests to the application server. The requests received by the edge server are sent from at least one client device through the public network and authenticated by the secondary firewall. The application server is configured to receive the relayed subset of requests and perform a second subset of the services in response to the relayed subset of requests. The relayed subset of requests received by the application server are authenticated by the primary firewall.
