Embodiment Construction

[0050] The subject matter is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of subject matter. It is understood that the subject embodiments may be practiced without these specific details.

[0051] According to a non-limiting embodiment of the present disclosure, a method and apparatus for generating a backward compatible video stream representative of immersive video is described. The format of such a stream is also described. According to another non-limiting embodiment of the present disclosure, a rendering device capable of rendering video upon receipt of such a stream, and a method by the device for compositing the video to be rendered according to the format of the stream are presented.

[0052] The present disclosure proposes capturing at least a po...

Abstract

The present disclosure relates to methods, devices, and processor-readable media for generating streams and compositing video for rendering devices. At least one traditional rectangular video is captured (82) from the immersive video obtained from the source. A collection of camera control data is used to determine which parts of the immersive video will constitute traditional video (84). These parts are removed from the immersive video (83) and each prepared video is packaged in a stream (85). Structures from streams are containers. Informative data about the position and size of the removed part can be added to the stream.

Description

technical field [0001] This disclosure relates to the field of formatting backward compatible streams representing immersive video, for example when such streams are distributed to a diverse collection of client devices, some configured to display traditional rectangular video, Other client devices are configured to display immersive video. Background technique [0002] Immersive videos differ from traditional videos in that they are displayed around the user rather than being projected on a rectangular screen in front of the user. Some devices are configured to render only traditional video (e.g., TV sets, video projectors), some are configured to render only immersive video (e.g., caves, geodes), and some devices can be configured based on They include decoders to render both types of video (e.g. head-mounted display device (HMD), tablet, smartphone). In this document, we will refer to a device that is configured to render immersive video and includes an adaptation codec...
