Abstract: An information processing apparatus according to an embodiment of the present technology includes a rendering unit and a generation unit. The rendering unit performs rendering processing on three-dimensional space data on the basis of field-of-view information regarding a field of view of a user, to generate two-dimensional video data corresponding to the field of view of the user. The generation unit generates a saliency map representing a saliency of the two-dimensional video data on the basis of a parameter regarding the rendering processing. This makes it possible to achieve distribution of a high-quality virtual video.

Abstract: The present disclosure relates to an image processing apparatus and an image processing method capable of suppressing degradation of subjective image quality while suppressing an increase in load.
On the basis of the display size of a point cloud object depending on the relative position of the point cloud object based on the position of a viewpoint, the necessary point density that is the density of points necessary for displaying the point cloud object is calculated, and the content file of LoD in which the density of points of the point cloud object is equal to or higher than the calculated necessary point density is selected. The present disclosure can be applied to, for example, an image processing apparatus, an information processing apparatus, a reproduction device, a 3D rendering device, an electronic device, a method thereof, and the like.

Abstract: The present disclosure relates to a media distribution device, a media distribution method, and a program enabling to generate a guide voice more appropriately. A media distribution device includes a guide voice generation unit that generates a guide voice describing a rendered image viewed from a viewpoint in a virtual space by using a scene description as information describing a scene in the virtual space and a user viewpoint information indicating a position and a direction of the viewpoint of a user; and an audio encoding unit that mixes the guide voice with original audio, and encodes the guide voice. The present technology can be applied to, for example, a media distribution system that distributes 6DoF media.

Abstract: A generation unit (111) generates an identification region map indicating whether or not each divided object data is visible from each position in a three-dimensional space by using information regarding orientation of a normal vector (15) dividing an object (10) in the three-dimensional space and information regarding an outline of the object (10).
