A client device adaptively streams a 360-degree video. A first segment is displayed based on a first viewing direction at a first time, where the first viewing direction is associated with a first viewport. The client requests a first base buffer segment based on the first viewport. The first base buffer segment has a presentation time after the first segment. At a second time, the viewing direction changes to a second viewing direction associated with a second viewport. The client requests, prior to the presentation time, a first viewport buffer segment based on the second viewport, with the same presentation time. The client device displays a second segment at the presentation time, wherein the second segment is either the first viewport buffer segment or the first base buffer segment. The client provides reports on viewport switching latency and on the most-requested segments.

Methods and apparatus to reduce latency for 360-degree viewport adaptive streaming

Methods and systems for improved content encoding are described herein. An encoder may allocate a time budget for encoding each frame of a content item. When the encoder takes longer than the allocated time budget to encode at least a portion of a given frame(s) of the content item at a first resolution, the encoder may take a number of actions in order to allow the encoder to 'catch up,' such as encoding frames at a second resolution. Once the encoder catches up and the allocated time budget is not being exceeded, the encoder may resume encoding frames of the content item at the first resolution.

Methods and systems for improved content encoding

Systems and methods are disclosed including techniques for rendering a 360-degree media content. Techniques disclosed include receiving a 360-degree media content and associated metadata that include a classification of a first spatial region from the received content. Techniques disclosed further include determining that a detected user movement is associated with a rendering of the first spatial region and determining whether the classification associated with the first spatial region complies with a stored user preference. If the classification violates the user preference, a path for gradually shifting the content rendering from a currently rendered spatial region to a spatial region that complies with the user preference is determined, and the received content is rendered according to the determined path.

Customized 360-degree media viewing

A method for receiving and displaying media content may be provided. The method may include requesting a set of DASH video segments that are associated with various viewports and qualities. The method may include displaying the DASH video segments. The method may include determining a latency metric based on a time difference between the display of a DASH video segment and one of: a device beginning to move, the device ceasing to move, the device determining that the device has begun to move, the device determining that the device has stopped moving, or the display of a different DASH video segment. The different DASH video segment may be associated with one or more of a different quality or a different viewport.

Metrics and messages to improve experience for 360-degree adaptive streaming

Methods and systems are described for low latency streaming. A computing device may receive a chunk of content. The computing device may determine whether a transmission duration of the chunk of the content satisfies a threshold. The computing device may determine a bitrate based on the transmission duration satisfying a threshold.

Methods and systems for low latency streaming

A device may be configured to render at least one spatial region of 360-degree media content, which may include two or more spatial regions. The device may include a receiver configured to receive the 360-degree media content and metadata associated with the 360-degree content. The metadata may include a classification of a respective spatial region of the 360-degree media content. The device may further include a memory configured to store a user preference and a sensor configured to detect a user movement. The device may include a processor configured to determine that the user movement is associated with a rendering of the respective spatial region. The processor may further determine whether the classification complies with the user preference and alter the rendering of the respective spatial region if the classification violates the user preference.

A method for receiving and displaying media content may be provided. The method may include requesting a set of DASH video segments that are associated with various viewports and qualities. The method may include displaying the DASH video segments. The method may indue determining a latency metric based on a time difference between the display of a DASH video segment and one of: a device beginning to move, the device ceasing to move, the device determining that the device has begun to move, the device determining that the device has stopped moving, or the display of a different DASH video segment. The different DASH video segment may be associated with one or more of a different quality or a different viewport.

Systems and methods in accordance with various embodiments of the invention enable quality based streaming. A content player in accordance with an embodiment of the invention includes: a processor; a network interface; and memory containing a content player application. The content player application can direct the processor to: receive quality metadata describing a plurality of streams, where: the plurality of streams are encoded at different maximum bitrates; each stream is divided into content segments; and the quality varies between content segments in each stream. Furthermore, the content player application directs the processor to measure available bandwidth; request content segments from the plurality of streams based upon the available network bandwidth and the quality metadata, where the requested content segments include content segments encoded at a maximum bitrate and having quality that is the lowest maximum bitrate that achieves a target quality level.
