Devices, systems, and methods are provided for enhanced parsing of manifest files for streaming media. A method may include receiving, by a media player, a first media manifest including tags indicative of first temporal segments for media content; identifying, using a parser, a first tag indicative of a first temporal segment; identifying, using the parser, a second tag indicative of a second temporal segment; parsing, using the parser, the first tag; based on at least one of the parsing or a user preference indicative of a starting location for playback of first media content of the media content or a preferred bandwidth, refraining from parsing the second tag; retrieving, by the at least one processor, based on a time associated with the first temporal segment, an address of the first video content; and presenting, by the at least one processor, the first media content based on the address.

Enhanced parsing of media manifests for streaming media

Techniques for a quality of service optimization using a content adaptive slate image in a media player application are described. According to some embodiments, a computer-implemented method includes sending a request for a video from a client device to a content delivery service that is separate from the client device; receiving, by the client device from the content delivery service, a manifest of the video and an intro slate separate from the manifest and separate from the video; displaying the intro slate on the client device; loading an initial frame of the video identified by the manifest onto the client device concurrently with the displaying of the intro slate; and displaying the video on the client device after the displaying of the intro slate.

Computer-implemented methods for quality of service optimization using a content adaptive slate image

Systems, methods, and computer-readable media are disclosed for providing a nonlinear, dynamic, and prioritized content caching scheme for segmented content during playback. Certain embodiments provide new techniques for optimally determining preferred content, prioritizing the preferred content for download and consumption, and, in systems where storage and memory systems are constrained, utilizing the same prioritization system for optimized garbage collection. Example methods may include determining a current playhead position associated with a video playback. Certain methods include determining a cache priorities for fragments based on the current playhead position and the positions of the fragments in the video playback. A first fragment may be the next fragment with respect to the linear playback, and a second fragment may follow the first fragment. Certain methods include determining that the second cache priority is higher than the first cache priority and providing the second fragment to a user device.

Nonlinear dynamic prioritized content caching for segmented content

Methods and apparatus are described for efficiently representing manifests and playlists for media presentations. Some media streaming protocols include repetition syntax by which a sequence of media segments having the same duration can be represented with a single entry. A pattern syntax is introduced by which repeating patterns of segment durations in a cycle may be represented in manifests and playlists.

Higher order manifest data compression

Techniques for adaptive backfilling of media fragments are described. As one example, a computer-implemented method includes sending, by a media player, a request for a plurality of media fragments from a content data store, receiving the plurality of media fragments from the content data store with at least one media fragment at a first quality level into a front buffer of the media player via a network, starting playback of the plurality of media fragments from the front buffer after a startup threshold number of media fragments are received in the front buffer, detecting when a backfill threshold of the media player is exceeded by a backfill indicator, and replacing at least one of the plurality of media fragments at the first quality level in the front buffer of the media player with a second, higher quality level variant via the network when the backfill threshold is exceeded.

Adaptive media fragment backfilling

Methods and apparatus are described for stitching independently encoded content streams together such that they appear to be part of a single streaming session.

Stitching content streams together

Methods and apparatus are described for providing media presentations that include content originating from multiple sources. Techniques disclosed include server-side logic for inserting secondary content, such as advertisements, into primary content, such as a VOD presentation. Systems implementing the disclosed techniques can support different viewer device capabilities relating to displaying media presentations that include content from multiple sources.

Manifest data for server-side media fragment insertion

Techniques are described for handling temporal overlaps that occur between fragments of streaming media content, such as between a fragment of primary media content (e.g., a live sporting event) and a fragment of secondary media content (e.g., ad media content) dynamically inserted into the stream.

Media timeline management

Methods and apparatus are described for partitioning a manifest file to generate smaller manifest files for media content playback. A server partitions a manifest file prior to receipt of a request from a client or in response to a request from a client for a manifest for media content for a particular temporal range or subset of playback options.
