A system obtains a data set representing immersive video content for display at a display time, including first data representing the content according to a first level of detail, and second data representing the content according to a second higher level of detail. During one or more first times prior to the display time, the system causes at least a portion of the first data to be stored in a buffer. During one or more second times prior to the display time, the system generates a prediction of a viewport for displaying the content to a user at the display time, identifies a portion of the second data corresponding to the prediction of the viewport, and causes the identified portion of the second data to be stored in the video buffer. At the display time, the system causes the content to be displayed to the user using the video buffer.

An image processing method comprises receiving content; displaying the content on a display; detecting a capture trigger for capturing a screenshot of the content displayed on the display; acquiring additional information relating to the content displayed on the display at a capture timing corresponding to a timing at which the capture trigger is detected; and capturing the screenshot of the content displayed on the display at the capture timing and adding the additional information to the screenshot to generate an additional-information-added image.

A reception device is provided. The reception device includes a high definition multimedia interface configured to receive first video data of a first high dynamic range video and first characteristic information for an electro-optical conversion of the first video data, the first characteristic information including a first value for the electro-optical conversion of the first video data when a first high dynamic range curve is to be indicated and a second value for the electro-optical conversion of the first video data when a second high dynamic range curve is to be indicated. The reception device includes reception circuitry configured to receive second video data of a second high dynamic range video and second characteristic information for electro-optical conversion of the second video data. The reception device further includes a video decoder, electro-optical conversion circuitry, and a display.

A hand-held turbine cleaning tool includes front and rear housings coupled to each other, an outlet at one end of the tool, and a top of the tool at an opposed end. The outlet is directed in a first direction away from the top. An inlet is disposed between the outlet and the top and is also directed in the first direction. A diverter valve at the inlet is moveable between on and off positions. The on position directs water flowing into the inlet from the inlet, up to the top in a second direction opposite the first direction, and then down to the outlet in the first direction. A turbine at the top has a turbine shaft that extends outside the tool. An abrasive member is connected to the turbine shaft and is configured to rotate when water flows from the inlet to the outlet.

In accordance with embodiments, a method of transmitting a video includes inter-view redundancy removing pictures for multiple viewing positions; packing inter-view redundancy removed pictures; and/or encoding the packed pictures and/or signaling information including center view generation information, pre-generation information, view synthesis recommendation information and/or reference view information. In accordance with embodiments, a method of receiving a video includes decoding a bitstream of the video based on viewing position and/or viewport information, unpacking pictures in the decoded bitstream; view regenerating the unpacked pictures; and/or view synthesizing the view regenerated pictures.

Method, systems, and computer-readable media are provided to facilitate content discovery based on augmented context. A first set of images of a graphical display may be acquired and analyzed to identify visual characteristics of an object represented. Attributes of the object may be identified. Specifications may be transmitted to the television receiver and/or a remote data source in order to pull matching information. A user-selectable interface element may be generated for presentation as an option to take an action relating to the object represented. A visual output of the interface element may be output as an overlay on the first set and/or a second set of images displayed by the computing device. A user selection responsive to the outputting of the visual output of the at interface element may be processed. A communication may be transmitted to the television receiver to cause the action responsive to the user selection.

There are disclosed various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments the method for video encoding comprises obtaining compressed volumetric video data representing a three-dimensional scene or object (71); capsulating the compressed volumetric video data into a data structure (72); obtaining data of a two-dimensional projection of at least a part of the three-dimensional scene as seen from a certain viewport (73); and including the data of the two-dimensional projection into the data structure (74).

An encoding method and a decoding method. The encoding method includes generating curved image by creating projection of visual scene onto inner surface of imaginary 3D geometric shape that is curved in at least one dimension; dividing curved image into input portion and plurality of input rings; encoding input portion and input rings into first planar image and second planar image, respectively, such that input portion is stored into first planar image, and input rings are packed into corresponding rows of second planar image; and communicating, to display apparatus, first and second planar images and information indicative of sizes of input portion and input rings.

The disclosure provides a video transmission method for virtual reality. The method includes reorganizing a first video and a second video obtained to generate a third video suitable for transmission through a physical wire, hence avoiding distortion caused by compression of a high-definition video. The disclosure further includes a video processing device and a video generating system employing the video transmission method.

Provided are an information processing device, an information processing method, a reproduction processing device, and a reproduction processing method that reduce the amount of information and provide a viewer with a high-quality viewing experience. A preprocessing unit individually generates SubSample information used for decoding each of SubSamples, which are a plurality of component streams, in a content stream including the SubSamples. The file generation unit generates a file including the SubSamplel information generated by the preprocessing unit.
