Abstract: A method of content replacement with onscreen displays. The method can further include sending an overlay request to provide overlay content and an overlay format. The method can include receiving the overlay content and the overlay format selected in view of overlay parameters. The method can include superimposing the overlay content over the media content using the overlay format. The method can include detecting a presence of an onscreen display. The method can include determining a location of a portion of the onscreen display that extends underneath the overlay content. The method can include defining a window in the overlay content that corresponds to at least the location of the portion of the onscreen display. The method can include setting a transparency level of the overlay content in the window to permit the portion of the onscreen display to be at least partially visible through the overlay content.

Abstract: The present invention provides a system and methods for allowing any two users each on H.323 compliant systems to conduct calls, specifically video conference calls, in the presence of one or more network address translator (NAT) devices that separates users on an internal private IP network from users on an external public network. The video conference calls according the system and methods of the invention may be performed with Internet directory assistance. Additionally, the video conference calls may be performed through a dual NAT system configuration wherein two users, each on separate private networks, communicate through their respective NAT systems via an external public network.
