摘要： An extended reality (XR) streaming system (10) with integrated copyright protection is described. The XR streaming system (10) comprises an asset database (30) and at least one XR streaming instance (26). The asset database (30) 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 (26) to render an XR image associated with the respective digital asset. The XR streaming instance (26) is configured to generate an asset request, wherein the asset request corresponds to a request for a particular digital asset. The asset database (30) is configured to transmit the rendering data associated with the requested digital asset to the at least one XR streaming instance (26) based on the asset request and based on the copyright data. The at least one XR streaming instance (26) is configured to generate an XR image stream based on the transmitted rendering data. Further, an XR streaming method is described.

- 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 module (24), wherein the machine-learning module comprises a machine-learning model that is pretrained 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 module (24), 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 (12).
Further, an XR projection system (10) and a machine-learning module (24) are described.-

摘要： A multi-viewer extended reality (XR) streaming method for streaming XR images between a plurality of XR application instances (26) and a plurality of XR devices (12) is described. The multi-viewer XR streaming method comprises the following steps:
- streaming, by means of a first XR application instance (26) of the plurality of XR application instances (26), first XR images to at least one XR device (12), wherein the first XR images correspond to virtual content viewed from a first spectator position (38);
- determining a position of the at least one XR device (12) relative to the first spectator position (38); and
- reprojecting, by means of the at least one XR device (12), the first XR images based on the determined position of the at least one XR device (12).
Further, an XR streaming system (10) is described.-
