A method and apparatus are provided for a first controlled device, such as a wireless local transmitter that accepts a plurality of digital audio signals and corresponding program information signals converted from a controlled source, such as the encoded digital data provided by a digital data signal source, typically a community antenna television (CATV) cable or direct broadcast satellite, then modulates said digital audio and corresponding program information signals on different carrier frequencies and transmits the modulated signals to a plurality of second controlled devices, such as remote digital receiver / tuners that demodulate said signals to output music in stereophonic sound and display the corresponding program information by means of an alphanumeric display. The first and second controlled devices contain microprocessor systems for communicating, controlling, storing, processing, and display of digital data within the operation of the respective system. A high speed, error free digital signal protocol is utilized for transmitting digital audio and corresponding program information signals to and from the digital receiver / tuner. The digital data transmitter and digital receiver / tuners utilize the 44.1 kilohertz (kHz) Compact Disc (CD) clock signal embedded in digital audio signals provided by an established delivery system to derive clocking signals for reception and processing of digital audio signals and for implementing the display information communications protocol.

Embodiments of the present invention provide systems and methods for capturing on-demand media content for use with portable media devices, including wireless phones, using a based station to provide for enhanced signal strength capture. These embodiments provide for the reception / distribution of on-demand media content, which can include, among other things, video content (such as television programming, movies, etc.), audio content (such as radio programming, audio recordings, etc.), data content (such as Internet data—web pages, electronic mail, etc.), voice transmissions (such as telephone transmissions, etc.) and / or the like.

Radio waves transmitted from the antenna of a broadcasting station are received by the antenna of a television receiver. The television receiver extracts an EPG from the received radio waves and transmits it to a remote controller via an infrared transmission / reception section. The remote controller displays the received EPG on a LCD and is then rendered in a state of waiting for selection of a program. If some program is selected and then a reserve button is manipulated, the remote controller transmits a control command for a recording reservation to a video tape recorder. The video tape recorder receives the control command with an infrared transmission / reception section, whereby the recording reservation of the designated program is set.

A digital broadcasting transmitting unit multiplexes a content exclusively used for remote controller in addition to contents of programs A and B and transmits the multiplexed contents. A digital broadcasting receiving unit separates the multiplexed contents and transmits the content exclusively used for remote controller to a bidirectional remote controller. The bidirectional remote controller displays the received content exclusively used for remote controller on a display thereof.
