    Abstract: Systems, methods, and computer-readable media are disclosed for dynamically inserting secondary content into a live stream or a video on demand (VOD). The secondary content can include, for example, a public service announcement or warning, censoring content, live or prerecorded commentary, an advertisement, or any other type of content to be integrated with or inserted into the main content. Example methods may include receiving a content stream including a first fragment having a first duration and a second fragment having the first duration. Certain methods may include determining an increased quality of service associated with encoding the content stream into fragments having a second duration. Certain methods may include generating, based at least in part on the increased quality of service, a third fragment having the second duration, and sending the content stream having the third fragment to a user device.

    Abstract: Methods and apparatus are described for automating aspects of the annotation of a media presentation. Events are identified that relate to entities associated with the scenes of the media presentation. These events are time coded relative to the media timeline of the media presentation and might represent, for example, the appearance of a particular cast member or playback of a particular music track. The video frames of the media presentation are processed to identify visually similar intervals that may serve as or be used to identify contexts (e.g., scenes) within the media presentation. Relationships between the event data and the visually similar intervals or contexts are used to identify portions of the media presentation during which the occurrence of additional meaningful events is unlikely. This information may be surfaced to a human operator tasked with annotating the content as an indication that part of the media presentation may be skipped.

    Abstract: Techniques are described for providing media presentations that include content originating from multiple sources in ways that are effectively transparent to end user devices. Manifest data provided to an end user device include a key encoded in the URL for each of the content fragments. The key encodes one or more interstitial periods of secondary content within the overall presentation of primary content. When a media server receives a content request from the end user device, the media server determines from the key encoded in the URL and the range of content requested whether the request corresponds to the primary content or the secondary content.
