Abstract

Information from a handheld electronic device can be shown on a video screen that is remote from the electronic device. More particularly, information can be provided within a handheld electronic device, and communicated from the handheld electronic device to a receiver over a wireless coupling. A video signal is generated responsive to the information communicated over the wireless coupling, and the video signal is provided for display on the video screen. More particularly, the information can be communicated over the wireless coupling according to a Bluetooth protocol. Related methods, systems, and devices are discussed.
