An information distribution and processing system contains a remote site, a sender and a receiving apparatus. The remote site contains a first set of digital data. The sender delivers a second set of digital data to the receiving device. In one embodiment of the present invention, the receiving device contain a timing device for automatically receiving the second set of digital data at predetermined times. The second set of digital data contains a first set of displayable data, a second set of displayable data, at least one non-displayable symbol, and at least one linking reference associated with the second set of displayable data. If desired, a user can select the second set of displayable data. The associated linking reference is sent to the remote site. The associated linking reference is used by the remote site to search for the additional information, and returns the requested information to the user.

A terrestrial digital video broadcasting (DVB-T) network is used to transmit IP datagrams to receiving devices using multiprotocol encapsulation (MPE). MPE datagram sections and forward error correction (FEC) datagram sections are transmitted in separate time-sliced bursts using transport stream packets with different packet identifiers (PIDs).

Systems and methods for remotely scheduling tasks that are transmitted to a set top box and implemented on the set top box. A task service includes a website that provides program guide data to users. From the program guide data, a user selects a task. The website generates a notification that includes the task and certain identifiers, including a set top box identifier and a sequence number. The notification is sent to a notification service, that repeatedly sends the notification to a broadcast service. The broadcast service ensures that the notification is transmitted to the set top box. The set top box detects the notification from the set top box identifier and implements the task on the set top box unless the task has been previously handled.

A personal video recorder (PVR) enabled set-top box (STB) may be operable to store an advertisement and associated playback control information received from a media provider into a storage device in the PVR enabled STB, schedule the stored advertisement for viewing based on the associated playback control information. The PVR enabled STB may be operable to insert the stored advertisement into media content for one or more times based on the scheduling. The PVR enabled STB may be operable to cause display of the stored advertisement and the media content in different transport formats. At a forward / reverse playback position during a PVR playback, the PVR enabled STB may be operable to cause display of the stored advertisement when a play count associated with the stored advertisement is less than a count threshold at the forward / reverse playback position.

A system for decoding data, such as travel and traffic information, configured in data blocks embedded in an electromagnetic signal, such as a broadcasted radio signal, has been developed. The system includes a method and receiver for decoding the data with a background tuner in a manner that does not impair the ability of the background tuner to demodulate other signals. While a main tuner is tuned to demodulate a first electromagnetic signal to produce a data stream, the background tuner is switched to decode the data blocks only when the data blocks are expected to be received. In the remaining time, the background tuner is free to demodulate other signals to support a diversity or other function. If a data block is not received, or not received when expected, the background tuner returns to demodulating one or more other frequencies after a predetermined time interval has elapsed.

Data broadcast over different channels may be updated in a digital broadcast receiving device. The device may include a receiver unit, a processor, memory instructions embodied in the memory for execution on the processor. The instructions may be configured to implement the method for updating data broadcast over different channels. A first digital broadcast signal may be received over a first channel. The receiving device may be tuned to a second channel at a predetermined time to receive a second digital broadcast signal. Selected data may be extracted from the second digital broadcast signal and stored or utilized with the receiving device. An update schedule may be generated for data transmitted with a digital broadcast signal. A broadcast time for an update packet may be determined from a packet header. A schedule packet may be generated containing the broadcast time and broadcast before the update packet.

A system and method is disclosed for a personal radio recorder. The personal radio recorder allows for random access of communication signals by identifying a channel and time. The personal radio recorder is capable of concurrent reception, storage and playback of a complete spectrum of individual communication signals. A wide-band signal is received, and concurrently demodulated into a plurality of individual communication signals. These audio signals are identified by channel and time. Individual signals may be simultaneously played, paused, or stored for later playback. Compression may be used to make efficient use of storage. Storage may be fixed, removable, or a combination of both. The system is also capable of storing signals that are already digitally formatted, and is compatible with existing analog or digital playback devices. The personal radio recorder may playback multiple channels of communications data, either previously recorded or currently broadcast, to multiple output stages at the same time.

A receiving apparatus includes a receiving unit configured to receive a broadcast program, an output unit configured to output video data of the broadcast program received by the receiving unit to a monitor apparatus, a reservation setting unit configured to set reservation of receiving a broadcast program selected from a plurality of broadcast programs, the reservation unit generating reservation information including broadcast start time of a selected broadcast program, a notification unit configured to, based on the broadcast start time included in the reservation information, notify an external apparatus before the broadcast start time that the broadcast start time is approaching, a communication unit configured to receive an operation instruction from the external apparatus, and a control unit configured to control the tuner and the output unit to receive a broadcast program designated by the reservation information and to output video data of the received broadcast program when the communication unit receives an operation instruction for a request for viewing from the external apparatus after the notification indicating that the broadcast start time is approaching.

Optimizing ‘actual’ and ‘other’ table type EPG information acquisition. In a broadcast stream multiplex, information is comprised in event information tables of type ‘actual’ that comprises event or program information about a selected service, and of type ‘other’ that comprises event information about other services in the multiplex. An EPG database is updated with the event information comprised in the event information tables under certain conditions only.

A method, apparatus, and computer instructions for dynamic radio station tuning in a data processing system. A play list is identified. The play list is a user-defined list and includes an identification of a number of songs. Music information is obtained from a plurality of radio stations. This music information is compared to the play list to generate a schedule. Dynamic tuning to a radio station within the plurality of radio stations is performed using the schedule to present songs from the number of songs to a listener.
