A media system includes a plurality of set-top boxes coupled to a coax network and a controller. The controller displays a first passkey to a user in response to receiving a request from the user to activate playback of a media content on a particular set-top box. The set-top box receives the first passkey from the user and determines whether the user is authorized to activate playback of the media content by comparing the first passkey received from the user with a second passkey obtained from a passkey module on the set-top box. When the user is determined by the set-top box to be authorized to activate playback of the media content, the set-top box determines a radio frequency channel of the coax network according to the first passkey received from the user and begins playback of the media content received on the radio frequency channel on a display device.
