Abstract: An appliance device is configured to share content in a zone window. A content sharing session may be initiated by a user on the appliance device to share content with at least one client device. In response, the appliance device may display a zone window that is transmitted, via a content stream, to the at least one client device which displays the zone window. The appliance device may detect that a first digital asset has been added to the zone window by a user. In response, the zone window including the first digital asset is transmitted, via another content stream, to the at least one client device which displays the zone window with the first digital asset. In this manner, assets may be dynamically added to a zone window and automatically shared with client devices without requiring restart or interruption of the content sharing session.
