Embodiment Construction

[0051] A detailed description of illustrative embodiments will now be described with reference to the various figures. While this specification provides detailed examples of possible implementations, it should be noted that these details are intended to be illustrative and not to limit the scope of the application in any way.

[0052] VR systems can use one or more omnidirectional videos. For example, one or more omni-directional videos may include one or more 360-degree videos. The 360-degree video can be viewed from a 360-degree angle in the horizontal direction and a 180-degree angle in the vertical direction. VR systems and 360-degree video can be used for media consumption beyond Ultra High Definition (UHD) services. Free View TV (FTV) can test the performance of the solution. For example, FTV may test the performance of 360-degree video (eg, or omni-directional video)-based systems and / or multi-view-based systems.

[0053] A VR system may include a processing chain. ...

Abstract

Systems, methods, and instrumentalities may be provided for discounting reconstructed samples and / or coding information from spatial neighbors across face discontinuities. Whether a current block is located at a face discontinuity may be determined. The face discontinuity may be a face boundary between two or more adjoining blocks that are not spherical neighbors. The coding availability of a neighboring block of the current block may be determined, e.g., based on whether the neighboring block is on the same side of the face discontinuity as the current block. For example, the neighboring block may be determined to be available for decoding the current block if it is on the same side of the face discontinuity as the current block, and unavailable if it Is not on the same side of the face discontinuity. The neighboring block may be a spatial neighboring block or a temporal neighboring block.

Background technique [0003] Virtual reality (VR) is being used in many application areas including, but not limited to, healthcare, education, social networking, industrial design / training, gaming, movies, shopping, entertainment, and / or similar applications. VR can, for example, enhance the viewer's experience by creating a virtual environment around the viewer and generating a realistic feeling of "being there" for the viewer. VR systems can support interaction through gestures, gestures, eye gaze, voice, and more...
