360° Adaptive Streaming with Viewport Switching and Latency Metrics

The patent segments the 360° video content into multiple spherical video segments corresponding to different viewport regions. Instead of transmitting the entire 360° video, only the relevant viewport segments are transmitted to the client device. This segmentation allows the system to maintain low-latency rendering by providing timely access to needed video portions while dramatically reducing bandwidth consumption by excluding unnecessary regions from transmission.

The patent implements local quality by encoding different viewport regions with different quality levels based on their importance and expected viewing probability. High-priority viewports receive higher quality encoding while low-priority regions use lower quality or are omitted entirely. This approach enables low-latency rendering for critical viewports while reducing overall bandwidth consumption through selective quality distribution.

The patent applies local quality by assigning different quality levels to different spatial regions within the 360° video content. Viewport regions that are more likely to be viewed or are currently active receive high-quality encoding, while peripheral or less important regions are encoded at lower quality or excluded. This maintains high video quality for the user's actual viewing experience while significantly reducing the total file size by not uniformly encoding all regions at high quality.

The patent segments the 360° video into multiple spherical segments representing different viewport regions. By segmenting the content, the system can selectively transmit and encode only the necessary portions at high quality, rather than encoding the entire 360° sphere uniformly. This reduces overall file size while maintaining high quality for the relevant segments that contribute to user experience.

The patent segments the 360° video into multiple spherical video segments corresponding to different viewport regions. This segmentation enables the system to transmit only the specific segments needed for the user's current viewport rather than the entire 360° video. The client device can still access and render different portions by requesting different segments, maintaining viewport flexibility while eliminating bandwidth waste through selective transmission.

The patent implements dynamic viewport-based streaming where the system adaptively determines which spherical video segments to transmit based on the user's current viewport orientation and movement. As the user moves their viewport, the system dynamically adjusts which segments are transmitted next, ensuring bandwidth is used efficiently for actual viewing needs while maintaining the ability to access any portion of the 360° content as required.
