To support 360 virtual reality video streaming services, high resolutions of over 8K and
network streaming technology that guarantees consistent quality of service are required. To …

Heterogeneous spatial quality in 360-degree videos is characterized by regions of high and
low quality appearing in the same video chunk. Encoding quality-varying omnidirectional …

Abstract Systems, methods, and instrumentalities are disclosed for a 360-degree video
streaming. A video streaming device may receive a 360-degree video stream from a network …

Information-centric networking (ICN) is a future Internet architecture that makes it possible to
effectively use various in-network functions, such as cache storage, computing resources …

The existing viewport-adaptive 360-degree video streaming schemes encode tiled 360-
degree videos with digital-based compression. However, these schemes cause a cliff effect …

Portion-or tile-based video streaming concepts are described. In one example aspect, a
server includes a processor that is configured to provide a manifest file to a client. The …

Boundary extension refers to the extension of a picture boundary to enable inter prediction
from regions outside the picture. In current video coding schemes, only non-adaptive …

An encoder and a decoder are provided for encoding, and decoding pictures, respectively.
The encoder defines a structure for a picture segment by dividing the picture into multiple …

360-degree video delivery in Virtual Reality is very challenging due to the fact that 360-
degree videos require much higher bandwidth than conventional videos. To overcome this …
