A method enables video surveillance service subscribers to share image streams with individual first responder agencies in the event of emergency. A customer administrator selects permissions on each camera via privileged web-browser or mobile device. Permissions enable selection by static meta data such as type, audio, location, motion, recognition, spectrum, and epoch. Setting ranges of time controls access to video streams of present and past epochs. Under control by a customer administrator, a virtual machine dedicated to each responding agency instantiates a video server. A camera is shared by a customer administrator's selection of permissions on each camera via privileged web-browser or mobile device. Video streams of present and past epochs are controlled by ranges of time. A notification is customized for each responding agency and each event by dynamically generating a link to a secure webserver which records geo-location or network identifiers for validation.

An apparatus including circuitry configured for receiving a spatial media content file including a plurality of viewpoints; circuitry configured for determining a first viewpoint from the plurality of viewpoints for a first user consuming the spatial media content file; circuitry configured for receiving an indication that affects an audio rendering of the first viewpoint for the first user, wherein the indication is associated with one or more actions of at least one second user consuming the spatial media content file; and circuitry configured for controlling the audio rendering of the first viewpoint for the first user in response to the receiving of the indication based on at least one of: a position and/or orientation of the first user, and the one or more actions of the second user.

There is provided a technology capable of reducing the processing load on a server apparatus side in cloud rendering. A server apparatus according to the present technology includes a controller. The controller groups terminal apparatuses each having a viewing position within an identical segment on the basis of viewing position information of each terminal apparatus within a viewing region including a plurality of segments, and transmits common video information to each of the grouped terminal apparatuses by multicasting.

A content display apparatus includes: a state identifying part that identifies a state of a viewer who is to view content; an image data selecting part that selects a plurality of pieces of image data from a plurality of image data candidates on the basis of the state of the viewer identified by the state identifying part; a content generating part that generates state improvement content for improving the state of the viewer by determining an order in which to display the plurality of pieces of image data; and a display control part that causes a display part viewed by the viewer U to display the state improvement content.

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.

Methods and/or apparatus provide for obtaining intrinsics and extrinsics of a plurality of cameras arranged to capture a scene and based thereon, generate a voxel representation of the scene; obtaining extrinsics and intrinsics of a virtual camera; mapping the extrinsics and intrinsics of the virtual camera to at least one voxel surface defined in a data structure and to identify at least one camera pair suitable for obtaining depth data for that voxel surface based on the corresponding camera pair identifier; and receiving an input from the mapping unit, and in response obtaining images captured by the cameras in the at least one camera pair identified as being suitable for reconstructing the scene from the viewpoint of the virtual camera, and to generate an image of the scene from the viewpoint of the virtual camera based on the obtained images.

Methods, devices and stream are disclosed to encode and decode a volumetric content. At the encoding, the space of the volumetric content is divided in distinct sectors according to at least two different sectorizations. One atlas is generated for each sectorization or a single atlas is generated encoding all the sectorizations. At the decoding, a sectorization is selected according to the current direction and field of view, according to user's gaze navigation and according to prediction of the upcoming pose of the virtual camera controlled by the user. Sectors are selected according the selected sectorization and the current direction and field of view and only patches encoded in regions of the atlas associated with these sectors are accessed to generate the viewport image representative of the content seen from the current point of view.

The present disclosure relates to a system and method for synchronous video display on at least one display. The method may comprises receiving a channel of video signal from each data acquisition port of a plurality of data acquisition ports during a time interval, each channel of video signal comprising a plurality of video frames captured during the time interval. The method may also comprises assigning a count value for each video frame of the channel of video signal as synchronization information for each video frame of the channel of video signal to form a pool of video frames each corresponding to a count value. The method may further comprises selecting video frames with the same count value from the pool of video frames as synchronized video frames, and transmitting, through the plurality of output ports, the synchronized video frames for synchronous display on the at least one display.
