## Abstract

A content management (CM) system is provided to centrally control operation of one or more connected devices by issuing control requests and/or data requests. In some situations the connected device(s) include devices that control presentation of television programming-related content, such as digital video recorder (“DVR”) devices and media center devices, and in other situations may include other types of media devices and/or other electromechanical (“E/M”) devices that may be centrally controlled, such as E/M devices for home automation that may operate independently or in conjunction with the media devices. In some situations, the CM system communicates with the connected devices via a network and using appropriate protocol(s), and may be accessed remotely via a network so as to allow a user to remotely operate the CM system. The CM system may further control searching, identification, selection, and presentation of pieces of media content by the connected device(s).
