    Abstract: When streaming content such as movies, music, or audiobooks for presentation, changes in conditions or unavailable frames may result in stutters or other negative experiences during presentation. Described herein are techniques and systems for extrapolating one or more frames based on previously received data. When an unavailable frame is determined, an interpolated frame is generated for presentation in place of the unavailable frame. The interpolated frame may be generated based on other frames that were received out of sequence, such as frames for presentation subsequent to the unavailable frame, as well as frames for presentation prior to the unavailable frame.

  • Patent number: 9473548
    Abstract: Described herein are systems and methods for determining and distributing pre-fetch data associated with streaming of content to a media device. Transport control data associated with user navigation within the content during consumption of the content is acquired. The transport control data is processed to determine one or more points of interest in the content. Pre-fetch content associated with these one or more points of interest may be delivered to the media device. Presentation is expedited with low or no latency during navigation to one of the points of interest having the pre-fetched content, which may be presented while the content is being made available.

During streaming, data transfer rates may temporarily drop below that needed to maintain presentation. Described herein are techniques and systems for repeating presentation of previously received video frames. This repeated presentation allows for presentation of the content to continue uninterrupted, while providing time for the data transfer rate to regain a level capable of maintaining the presentation.
