  • Publication number: 20180352017
    Abstract: The present disclose describes techniques for delivery and rendering of streamed media using error tags in a corresponding media playlist. The playlist may represent organization of the media item, providing information of coded media segments that constitute the media item. When segments of coded media are received for a media item, a determination may be made whether the coded media segments contain errors. When a coded media segment is encountered that does not contain an error, a playlist entry representing the coded media segment may be added to the playlist. When a coded media segment contains an error, a playlist entry may be added to represent this coded media segment. This playlist entry may indicate the segment error. The playlist may be stored for access by player device(s).

  • Patent number: 9917916
    Abstract: A media delivery service may include a media source, a proxy cache and one or more client devices. The media source may generate coded segments from an input media stream and develop a playlist identifying network locations of the segments. The media source may broadcast the coded segments and their storage locations to a proxy cache in a broadcast channel. The proxy cache may store successfully received coded segments and develop a mapping table identifying the segments' network locations. The client may request segments from the proxy cache based on the received playlist form the media source. If the proxy cache does not store a requested segment, it may so notify the client and the client may request the segment from the media source.

  • Publication number: 20170289514
    Abstract: Systems and methods for enabling playback control functions of a media player are disclosed. For example, a user of a client device receiving streaming playback of a video stream may perform rewind and fast forward control functions. The client device may implement these playback control functions by retrieving an enhanced playback segment. Using the enhanced playback segment, the media player may display selected frames at a predetermined interval while maintaining a visual cadence that is pleasing to a viewer. In the described embodiments, a client device may render a video stream, receive a command to control a fast forward or rewind playback mode for the video stream, and retrieve, from a distribution server or associated edge cache, one or more enhanced playback segments adapted to implement the user command.

  • Publication number: 20170289500
    Abstract: Techniques are disclosed for synchronizing media rendering among a plurality of networked terminals. A first terminal may receive communication from another terminal that correlates a network time to a first portion of a media item to be rendered on the terminals. The terminals may identify, from the correlation of network time to the first portion of media and from a playback rate negotiated between the terminals, other portions of the media item to be rendered at other network times. The terminals each may render appropriate portions of the media item as network time progresses. The terminals also may exchange other data to alter playback modes during the course of a common rendering session.

  • Publication number: 20170094354
    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.

  • Publication number: 20160372156
    Abstract: The present disclosure describes systems and techniques relating to generating three dimensional (3D) models from range sensor data. According to an aspect, frames of range scan data captured using one or more three dimensional (3D) sensors are obtained, where the frames correspond to different views of an object or scene; point clouds for the frames are registered with each other by maximizing coherence of projected occluding boundaries of the object or scene within the frames using an optimization algorithm with a cost function that computes pairwise or global contour correspondences; and the registered point clouds are provided for use in 3D modeling of the object or scene. Further, the cost function, which maximizing contour coherence, can be used with more than two point clouds for more than two frames at a time in a global optimization framework.
