    摘要: 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.

    摘要: 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.

    摘要: A terrestrial digital video broadcast (DVB-T) network includes a content provider and first to third transmitters. Each transmitter may transmit more than one signal, different signals having different frequencies, multiplexes and the like and relating to different network types. An integrated receiver/decoder (IRD) is mobile in the area around transmitters. As well as transmitting service information as part of a network information table on a data layer, the transmitters provide in their output signals transmitter parameter information as TPS data on a physical layer. This TPS information includes one bit identifying the type of the network to which the signal relates and information identifying whether or not the signal contains time-sliced data streams. This information is used by the IRD both in signal scan, or initialising the IRD with parameters needed for OSI layers service discovery, and for deselecting signals as handover candidates. Since the transmission parameter information is transmitted more frequently and in a lower OSI layer than the network information table, the IRD can more efficiently make decisions as to whether or not a signal is suitable for handover, or is otherwise a signal of interest.

    摘要: A method and an arrangement for defining a sub-table structure for SI tables, which may be used to split one big Service information (SI) table into several smaller tables. The splitting into the smaller sub-tables (Sub-Ts) requires less transmitted bandwidth because all the SI do not need to be broadcast to End User Terminal (EUT). Also, the sub-table division enables relatively easy creation of local SI tables because sub-tables can serve as a basis for local Transport Stream (TS) announcement. By dividing tables into smaller ones, the amount of unnecessary information transmitted for the EUT is reduced. The TSs of an entire broadcast network can be divided. Moreover, neighbouring, or adjacent, TSs (cells) can announce and advertise their content to each other, and further to the EUT. A sub-table (Sub-T) of the TS is sent to the adjacent TS. The preferable embodiments enable the EUT for moving in DVB network in a blinded manner being not specially informed about where or under which cell's coverage the EUT is. However, the EUT is able to obtain the information what content (TSs) is locally available because of the sub-table structure.
