Screen sharing for display in vr

A method of rendering image data provided by a sender system to a receiver system for screen sharing, wherein the receiver system is a Virtual Reality [VR] system, the method comprising, at the VR system:

• obtaining, from the sender system:
• image data representing visual content to be shared by the sender system with the receiver system, and
• render metadata which indicates at least in part how the image data is to be rendered in a virtual environment and which is generated based on legibility constraints imposed by the rendering or display of the virtual environment;
• and
• rendering the image data in the virtual environment based on the render metadata, wherein said rendering comprises projecting the image data onto a virtual canvas in the virtual environment.

A sender system configured for providing image data to a receiver system for screen sharing, wherein the receiver system is a Virtual Reality [VR] system configured to render the image data in a virtual environment by projecting the image data onto a virtual canvas, wherein the sender system comprises:

• a network interface to a network;
• a processor configured to:
• identify visual content to be shared with the receiver system;
• generate an adjusted version of the visual content which provides improved legibility when viewed in the virtual environment by adjusting a presentation of the visual content based on receiver metadata which is indicative of legibility constraints imposed by the rendering or display of the virtual environment;
• and
• using the network interface, provide image data representing the adjusted version of the visual content via the network to the receiver system.
