A system and method are disclosed for providing streaming data information to a receiver. The system accesses one or more information service providers for providing respective information signals, input buffers for storing portions of the streaming information, a digital broadcast transmitter for broadcasting the contents of the input buffers as transmission bursts, a digital broadcast receiver for receiving the transmission bursts for storage in a receiver input buffer, and an application processor for converting the transmission bursts to an information transmission stream. The digital broadcast receiver is synchronized with the transmitter broadcasts to allow for powering down between selected transmission bursts.

System and method for broadband digital broadcasting

A method, a system, a transmitter and a receiver for identification of a time sliced elementary streams using PSI/SI tables. This identification provides a way to separate time-sliced elementary stream from non-time-sliced elementary streams by defining two descriptors in PSI/SI tables. A time slice identifier descriptor is defined, which can be used to identify elementary streams which are time sliced. This descriptor is also used to provide additional information about the transmitted elementary streams. The invention provides a way to announce additional information of the time sliced elementary streams via PSI/SI tables. Additionally, it provides a mechanism to categorize single elementary stream(s) as non-time sliced and time sliced. A way to identify time sliced elementary streams carried over DVB networks is disclosed and providing additional information on those streams. This can be done by using the time slice identifier descriptor. The descriptor can be used at least in Network Information Table (NIT), Program Map Table (PMT) and IP/MAC Notification Table (INT) tables. Time slicing provides a way to save power in the receiver in broadband transmission.

Method, system and network entity for providing digital broadband transmission

A terrestrial digital video broadcasting (DVB-T) network is used to transmit IP datagrams to receiving devices using multiprotocol encapsulation (MPE). MPE datagram section and, if forward error correction (FEC) is used, MPE-FEC datagram sections may include time-slicing parameters, such as a 'delta-t' parameter for specifying a time until the next burst is transmitted and a flag for indicating the end of a burst. Thus, MPE and MPE-FEC datagram sections can be transmitted in bursts. Other types of sections, however, do not include such time-slicing parameters and thus cannot usually be transmitted in bursts. Nevertheless, by assembling a burst including at least one MPE or MPE-FEC datagram section which specifies delta-t and MPE or MPE-FEC datagram section at the end of a burst which indicates its position, other types of sections can benefit from being transmitted in bursts.

Burst transmission

A system and method are disclosed for providing streaming data information to a receiver. The system accesses one or more information service providers for providing respective information signals, input buffers for storing portions of the streaming inforamtion, a digital broadcast transmitter for broadcasting the contents of the input buffers as transmission bursts, a digital broadcast receiver for receiving the transmission bursts for storage in a receiver input buffer, and an application processor for converting the transmission bursts to an information transmission stream. The digital broadcast receiver is synchronized with the transmitter broadcasts to allow for powering down between selected transmission bursts.

An antenna (), mounted to a roof () of a building (), receives digital broadcast transmissions and feeds a signal through a cable () to a desk stand (). The desk stand has an amplifier and a loop antenna. A mobile telephone handset () capable of receiving digital broadcast transmissions also includes a loop antenna. Using inductive coupling, the signal is transmitted from the desk stand to the mobile telephone handset.

Extension device

A receiver modulecomprises a loop antennafor receiving signals from a digital broadcast network. The receiver modulemay be an integral component of, or attached to, a mobile terminalthat comprises a cellular transceiver. For example, the receiver modulemay be incorporated in a battery pack and inserted into a battery compartment of the mobile terminal, so that the receiver moduleand mobile terminalare powered by battery. The loop antennais substantially resistant to electric fields produced by the transceiverand other sources, and may be arranged within the receiver module. Where an external loop antennais provided instead of, or in addition to, loop antenna, the receiver modulemay be arranged to monitor the quality of signals received from the digital broadcast networkand alert a user to deploy the external antennaif the signal quality is low or decreasing.

Receiver module comprising a wideband antenna

A system that allows mobile terminals to periodically remove power from at least some components is disclosed. The mobile terminal receives bursts of content. Some of the bursts of content include relative time information identifying the transmission time of a subsequent burst of content. The mobile terminal may remove power from a receiving module during times when the mobile terminal is not scheduled to receive content bursts.

Clock-based time slicing

A method is presented for preventing the unauthorized use of a certain protected interface ( ) in a processor ( &prime;). An indication (NO PAT, ALARM) of attempted use of the protected interface is generated, and as a response to said indication, at least a major part of the operation of the processor is disabled (DISABLE).
