An information processing apparatus determines which of a first method for generating virtual viewpoint video upon receiving from an external apparatus object data used for generation of the virtual viewpoint video or a second method for receiving from the external apparatus virtual viewpoint video generated upon a virtual viewpoint designated for generation of the virtual viewpoint video to use as a delivery method for delivery of the virtual viewpoint video; and obtains the virtual viewpoint video by using the determined delivery method.

Sampled data is packaged in checkerboard format for encoding and decoding. The sampled data may be quincunx sampled multi-image video data (e.g., 3D video or a multi-program stream), and the data may also be divided into sub-images of each image which are then multiplexed, or interleaved, in frames of a video stream to be encoded and then decoded using a standardized video encoder. A system for viewing may utilize a standard video decoder and a formatting device that de-interleaves the decoded sub-images of each frame reformats the images for a display device. A 3D video may be encoded using a most advantageous interleaving format such that a preferred quality and compression ratio is reached. In one embodiment, the invention includes a display device that accepts data in multiple formats.

Methods, apparatuses and streams are disclosed for transmitting tiled volumetric video and, at the receiver, for generating an atlas image compatible with a legacy decoder. At the server side, viewport information is obtained and a first list of central tiles and a second list of border tiles are selected. A central tile is a part of an image obtained by projecting the 3D scene onto an image plane according to a central point of view. A border tile is an image comprising dis-occluding patches. Sizes and shapes of border tiles are function of size and shape of central tiles. At the client side, tiles are arranged according to a layout selected in a set of layouts according to the number, sizes and shapes of border tiles.

Aspects of the subject disclosure may include, for example, transmitting viewpoint information associated with a first portion of a three-dimensional (3D)/volumetric video to a device, wherein the viewpoint information comprises a first coordinate in 3D space associated with a first viewing direction in a playback of the first portion and a first timestamp associated with the first portion, receiving, from the device, a multiplane image (MPI) representation of a second portion of the 3D video responsive to the transmitting of the viewpoint information, and providing an image of the MPI representation to a display device. Other embodiments are disclosed.

The present invention provides an alignment state indicating apparatus and an alignment state indicating method implemented by the apparatus, the apparatus comprising: a case having an opening which is open so that an object in the form of light enters into the case; an image capturing unit which is disposed in the case, and receives light incident through the opening of the case to obtain raw data; a control unit which performs data connection and alignment between three-dimensional data generated through image capturing of the image capturing unit, and determines whether an alignment error has occurred; and an actuator which vibrates when the alignment error has occurred.
