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: System and methods for storing streamed media data to memory for future playback are provided. A device may stream media data associated with a movie over a network connection. The data streamed to the device will be saved to device memory and will then be playable offline. A manifest associated with the media data will be downloaded to the device and modified to reflect the location of the locally stored media data. During subsequent playback of the media data, the manifest will indicate that at least a portion of the media data exists in local memory. Some portions of the media data not stored locally may be subsequently retrieved from a remote source. The stored data may be updated or added to as necessary.

Abstract: A method of switching media output includes receiving a first variant of a media item with a player, transmitting the first variant to a secondary device, and upon determining a change in operating conditions, switching from the first variant of the media item to a second variant of the media item by estimating a time to perform the switch to the second variant, transmitting to the secondary device a notification of a time to switch from the first variant to the second variant, and transmitting the second variant to the secondary device.

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.

Abstract: Systems and methods use a new syntax defining a daterange tag that allows an author of a media stream to embed an arbitrary set of defined ranges in the media stream associated playlist. The defined ranges may be used to provide an overview of or otherwise define the playlist and media stream structure. When a playlist is updated and the timing window of the playlist advances, any daterange tags in the playlist that map to any defined range or media segment in the updated playlist will persist in the updated playlist. Any daterange tags in the playlist that map to defined ranges that have completed will be dropped from the updated playlist.

Abstract: Systems and methods for switching between encoded media streams are disclosed. A system may be configured to receive at least two media streams of differing qualities that are associated with an identical media asset. The system can seamlessly switch between a first media stream and a second media stream using an algorithm that can determine which frames of a second stream must be discarded to sync the second stream with the first media stream. The two media streams can then be cross faded to switch from the first media stream to the second media stream.
