  • Patent number: 9124931
    Abstract: A method of displaying content on a TV using over-the-top (OTT) processes where the viewer has a user experience similar to or identical with conventional TV usage. The viewer powers on the TV and the last channel or service that was watched is displayed wherein all the content is displayed using OTT and the viewer does not have to execute any other steps, such as going to an app menu and launching a TV app in order to watch OTT content. It is determined whether an input source for the TV is set to a virtual input source. A TV app that enables OTT viewing (viewing TV content via an IP network) is executed. Once the TV app launches, normal TV operations can be performed. The virtual input source of the TV is linked to the TV application.
