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.

A system according to claim 18, wherein the time slice identifier descriptor is carried in one or more program specific information or service information tables. 20. A system according to claim 19, wherein the one or more program specific information or service information tables comprise a network information table, program map table and IP/MAC notification table. 21. A receiver comprising: a processor; and memory storing computer executable instructions that when executed by the processor, cause the receiver to perform a method including: receiving a digital broadcast transmission as bursts; receiving information indicating a maximum burst duration of each burst; detecting parts, which are arranged to fit for saving power in the receiver, based on said received information, and switching at least part of the receiver on/off based on said received information. 22. A receiver according to claim 21, wherein information indicating the maximum burst duration is signalled in a time slice identifier descriptor. 23. A receiver according to claim 22, wherein the time slice identifier descriptor is carried in one or more program specific information or service information tables. 24. A receiver according to claim 23, wherein the one or more program specific information or service information tables comprise a network information table, program map table and IP/MAC notification table. 25. A receiver according to claim 21, wherein the receiver further comprises a mobile terrestrial digital video broadcasting receiver. 26. A receiver according to claim 25, wherein the information indicating the maximum burst duration is applied for saving power in the receiver, if a remainder of the burst is lost. 27. A receiver according to claim 25, wherein the receiver further comprises a mobile station for interaction with the digital broadcast transmission. 28. A transmitter comprising: a processor; and memory storing computer executable instructions that when executed by the processor, cause the receiver to perform a method including: transmitting a digital broadcast transmission as bursts; providing information indicating a maximum burst duration of each burst; categorizing parts, which are arranged to fit for saving power in a receiver, based on said provided information for switching at least part of the receiver on/off in accordance with said provided information. 29.
