streaming, by means of a first XR application instance of the plurality of XR application instances, first XR images to the at least one XR device, wherein the first XR images streamed by the first XR application instance are associated with a first XR application;
streaming, by means of a second XR application instance of the plurality of XR application instances, second XR images to the at least one XR device, wherein the second XR images streamed by the second XR application instance are associated with a second XR application, wherein the second XR application is a multi-user XR application; and
blending, by means of the at least one XR device, the first XR images received from the first XR application instance with the second XR images received from the second XR application instance, thereby obtaining blended XR images to be displayed on the at least one XR device.
Further, an XR streaming system is described.-

Abstract: An extended reality (XR) streaming system with integrated copyright protection is described. The XR streaming system comprises an asset database and at least one XR streaming instance. The asset database is configured to store asset data that is associated with a plurality of different digital assets, wherein the asset data comprises rendering data and copyright data associated with each digital asset. The rendering data corresponds to data that is necessary for the at least one XR streaming instance to render an XR image associated with the respective digital asset. The XR streaming instance is configured to generate an asset request, wherein the asset request corresponds to a request for a particular digital asset. The asset database is configured to transmit the rendering data associated with the requested digital asset to the at least one XR streaming instance based on the asset request and based on the copyright data. The at least one XR streaming instance is configured to generate an XR image stream based on the transmitted rendering data.

Abstract: A reprojection method for generating reprojected image data to be displayed on an XR device is described. The reprojection method comprises the steps of:
determining momentary position data;
generating preliminary image data based on the momentary position data;
determining updated position data;
inputting the momentary position data, the preliminary image data, and the updated position data into a machine-learning circuit, wherein the machine-learning circuit comprises a machine-learning model that is pre-trained to reproject the preliminary image data based on the momentary position data, the preliminary image data, and the updated position data; and
reprojecting the preliminary image data by means of the machine-learning circuit, thereby generating reprojected image data, wherein the reprojected image data corresponds to at least one reprojected XR image to be displayed on the XR device.-

Abstract: A computer-implemented method of generating augmented image data comprising depth information is described. The method comprises the steps of:
generating or receiving image data, wherein the image data comprises at least one frame having a first predetermined bit length, wherein the at least one frame comprises color information associated with pixels of at least one image;
generating or receiving depth data, wherein the depth data comprises depth information associated with the pixels of the at least one image; and
generating at least one augmented frame based on the image data and based on the depth data, wherein the at least one augmented frame comprises a color frame portion and a frame extension attached to the color frame portion.
The color frame portion corresponds to the at least one frame and has the first predetermined bit length. The color frame portion comprises the color information associated with the pixels of the at least one image. The frame extension has a second predetermined bit length, and wherein the frame extension comprises the depth information associated with the pixels of the at least one image.
