A communication device such as a smart phone is enabled for remotely controlling set-top boxes (STBs) over Internet protocol networks using an applet running on the communication device. Authentication from within a multimedia content distribution network may be achieved by verifying that a network identifier associated with the communication device is associated with an account that has granted access to the smart phone and that is associated with the controlled STB. A viewing pane on the communication device permits a user to remotely view content received on or available to the controlled STB.
