Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.

Abstract: The construction of virtual reality environments can be made more efficient with enhancements directed to the sizing of objects to be utilized in the construction of virtual reality environments, enhancements directed to the simultaneous display of multiple thumbnails, or other like indicators, of virtual reality environments being constructed, enhancements directed to controlling the positioning of a view of a virtual reality environment, enhancements directed to conceptualizing the virtual reality environment as perceived through different types of three-dimensional presentational hardware, and enhancements directed to the exchange of objects between multiple virtual reality environments being constructed.

Abstract: Systems and methods are provided for selectively controlling a carry mode for holograms presented in mixed-reality environments and for providing leashing buffers for the holograms. The carry mode enables holograms to be functionally moved within a single mixed-reality environment, and out into one or more different mixed-reality environments. The carry mode can be automatically applied to holograms created within the mixed-reality environment. The carry mode can also be applied responsive to user input applied to world-locked holograms, which triggers a switch from the world-locked mode to the carry mode from. Holograms can also be leashed for persistently displaying holograms associated with or linked to a user in the mixed-reality environment to provide the user increased accessibility to the hologram while navigating within and without a particular mixed-reality environment. Selectable options are presented with a hologram in carry mode for switching from the carry mode to the world-locked mode.

Abstract: The construction of virtual-reality environments is more efficient with adjustable virtual user input devices that accommodate user physical limitations. Adjustable virtual user input devices can be adjusted along pre-established channels, which can be anchored to specific points in virtual space, including a user's position. Adjustable virtual user input devices can be bent in a vertical direction, bent along a horizontal plane, or other like bending, skewing, or warping adjustments. Elements, such as individual keys of a virtual keyboard, can be anchored to specific points on a host virtual user input device, such as the virtual keyboard itself, and can be bent, skewed, or warped in accordance with the adjustment being made to the host virtual user input device. The adjustability of virtual user input devices can be controlled through handles, which can be positioned to appear as if they are protruding from designated extremities of virtual user input devices.
