A television message system is provided that allows users at user television equipment devices that are connected to a television distribution facility to transmit messages to each other relating to a television program or other suitable subject. The television message system permits users to participate in evaluations, contests, promotions, and surveys related to a television program while watching that television program. The television message system also permits users to compose and send a message to a television program entity. Users can send messages through the television message system to users at personal computers who are connected to the user's television distribution facility through a communications network. The television message system also allows a user to purchase a gift related to television programming for a recipient. The gift may be an electronic gift certificate for pay-per-view programming. The television message system may be based on an interactive television program guide or a set-top box application implemented on a set-top box.

Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's user station where selected music files are recorded. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to playback for their enjoyment. An antipiracy “ID tag” is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction. Music is transmitted on a fixed schedule or through an active scheduling process that monitors music requests from all or a subset of satellite receivers and adjust scheduling according to demand for various CD's. Receivers store selections that are likely to be preferred by a specific customer. In those instances where weather conditions, motion of atmospheric layers or dish obstructions result in data loss, the system downloads the next transmission of the requested CD and uses both transmissions to produce a “good copy”. In conjunction with the blanket transmission of more popular music, an automated CD manufacturing facility may be provided to manufacture CD's that are not frequently requested and distribute them by ground transportation.

In a data communication system such as a high capacity DBS system, dynamic mapping of broadcast resources is provided to exploit occasional redundancy in the program content of two or more input data streams, freeing at least one broadcast resource to carry alternate bitstreams, such as additional programs or existing programs at higher quality. Transmission maps defining the correspondence between input data streams and broadcast resources, and reception maps defining the correspondence between broadcast resources and output data streams, are updated as needed to dynamically modify broadcast resource mapping to increase effective utilization of available bandwidth. Beneficial n:n−y:m mapping in a high capacity consumer DBS entertainment system is provided. Apparatus and methods for efficiently generating, maintaining and updating allocation maps with reduced overhead requirements, are disclosed.

A viewer for displaying electronic books and having various features for restricting access to their content. A user may assign ratings to stored electronic books, or use standard ratings, and assign access levels to potential users. The ratings and access levels determine which electronic books, or portions of the electronic books, a particular user may access on the viewer.

The invention provides systems and methods for targeting broadcast messages to particular vehicles or classes of vehicles. In one embodiment, the system comprises an information center for creating and sending a broadcast data message, and a relay section that receives the broadcast data message and relays the message to a plurality of vehicles. The information center typically comprises a one-to-many communication system for sending the message from one source to a plurality of receivers, such as a satellite radio network or the like. The message can be deleted or modified in response to commands received by the receiver.

The present invention provides methods and apparatuses for configuring a modulator in a digital broadcast system using service information that is also broadcast to wireless terminals. In an embodiment of the invention, the service information is provided by a generator that encapsulates the service information in a transport stream that is received by a cell transmitter. The service information is parsed by each cell transmitter to determine the current modulator parameters. If at least one of the modulation parameters has changed, the associated modulator is reconfigured with the updated modulation parameters. The invention also provides methods and apparatuses for supporting repeaters in the digital broadcast system in order to provide supplementary RF coverage in associated cells. A repeater may retransmit a received radio signal at the same frequency or at a different frequency.
