Abstract: A variety of media devices may stream and present content such as movies, music, audiobooks, and so forth. During streaming, changing conditions or unavailable frames may result in stutters or other presentation problems. Described herein are techniques and systems for extrapolating one or more frames based on previously received data. The interpolated frames may be presented, reducing or eliminating the presentation problems.

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.

Abstract: A variety of media devices may stream and present content such as movies, music, audiobooks, and so forth. 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.

Abstract: Media devices streaming video from a server may use techniques to maintain presentation of content to one or more users. Described herein are systems and methods for determining which metadata to provide to the media devices for maintaining presentation of the content. The determination of which metadata to provide may be based on various factors such as the capabilities of the media device, the expected quality of service, and the amount of bandwidth between the server and the media device.

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.
