Abstract: Methods and systems provide techniques for managing media streaming and content distribution and management using time-based metadata. A video segment may include a gate with associated content that is accessible conditioned on consumption of the gate. The manner in which the gate manages access to the associated content may be defined according to rules and syntactical elements. For example, a gate may be unlocked or collapsed. An unlocked gate allows a user to skip the gate and access the gated content. A collapsed gate is automatically skipped. A gate may become locked or un-collapsed. Various commands, including fast forward, rewind, jump forward, and jump backward may respond to a gate based on its locked or collapsed status. Embodiments also provide pooling of gates and selection of a subset of gates for playing.

Abstract: A method of streaming media may include opening a single connection between a client device and a media source; requesting a first media segment of a media stream corresponding to selected tier of a media title over the single connection; determining a download bitrate of the single connection; comparing the download bitrate to a predetermined bitrate of the media title; and in response to determining that the download bitrate is less than the predetermined bitrate, opening a plurality of connections between the client device and media source. The predetermined bitrate may be a predetermined bitrate of a next higher bitrate tier in a group of tiers containing the selected tier when the selected tier is not a highest bitrate tier in the group, and a predetermined bitrate of the selected tier otherwise. The method may further include, in response to determining that an aggregate download bitrate of the plurality of connections is less than a multiple of a download bitrate of an individual one of the connections, closing some of the plurality of connections so that only the individual connection remains.

Abstract: Disclosed are systems, methods, devices and computer-readable media for image fetching for timeline scrubbing of digital media. In some implementations, a method comprises: receiving at a first time prior to receiving a scrub command, a first set of scrub images associated with digital media, the first set of scrub images having a first set of positions on a timeline of the digital media; receiving a first scrub command; receiving at a second time after the first time, a second set of scrub images associated with the digital media, the second set of scrub images having a second set of positions on the timeline that fill time gaps in the first set of positions on the timeline; animating, a timeline overlay including the timeline, a playhead and a scrub image window; and selecting a scrub image from the first or second sets of scrub images for presentation in the scrub image window.

Abstract: The present disclose describes techniques for delivery and playback of media using identifiers for offline playback, According to these techniques, a segment of media to be played may be identified from a manifest file. It may be determined whether the identical segment is available in local storage. When the identified segment is available in local storage, an identifier of the identified segment contained in the manifest file may be compared to an identifier of the segment in local storage. If the identifiers match, the segment may be played from local storage. Otherwise, the identified segment may be retrieved from a network location.

Abstract: An embodiment of a method of requesting a plurality of media streams can include, as performed by a computing device, receiving a control input to control a playback function of at least one of the plurality of media streams, determining a download bandwidth between the computing device and a media source on a network, classifying the at least one of the plurality of media streams based on the control input and total download bandwidth, and sending a plurality of requests for the plurality media streams over a single connection to the media source, wherein at least one of an order or a content of the requests is based on the classification. The sending of the media stream requests can utilize at least one of a server-side protocol for multiplexing media streams over a single connection or one or more of HTTP pipelining or HTTP range requests over a single connection.

Abstract: Methods and systems for switching between media streams can use a comparison of an average bandwidth for a new stream to an observed bit rate for an existing stream in order to determine whether to switch to the new stream. A check on the amount of data buffered for the existing stream can also be performed in order to determine whether a system should switch to the new stream.

Abstract: An accessory device may establish a short range link to a companion device, and the accessory device may use the companion device as a proxy to conduct a data session over a cellular network. Based on a latency requirement associated with the data session and/or a signal strength of the short range link, the accessory device may dynamically determine to transition its cellular radio from a powered-off mode to a low power mode.
