    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: Aspects of the invention are directed to service discovery in a digital broadcast network. A service discovery descriptor, which may be electronic service guide-provider and cell specific, provides mapping between a service identifier, a logical channel identifier, and a physical channel, which may be characterized by a frame identifier and a slot identifier, that is, each physical channel may have one or more slots within one or more frames. A neighboring service discovery descriptor provides mapping for the service available within neighboring cells. Aspects of the invention are directed to an encapsulation protocol that encapsulates variable length data, including, but not limited to, the service discovery descriptor and the neighboring service discovery descriptor, into fixed length data stream packets.

    摘要: The invention relates to a method for adjusting IQ-imbalance of a direct conversion receiver (200). In the method a radio frequency training signal is locally generating and conveyed to an in-phase branch and a quadrature-phase branch of the receiver (200). The method comprises mixing, in the analogue domain, the radio frequency training signal of the in-phase branch with a first mixing signal to form a baseband in-phase component (I) of the training signal and mixing, in the analogue domain, the radio frequency training signal of the quadrature-phase branch with a second mixing signal to form a phase shifted component (Q) of the training signal. The baseband in-phase component (I) and phase shifted component (Q) are analogue-to-digital converted to form a digital baseband in-phase component and a digital baseband phase shifted component of the training signal. In the method the digital baseband in-phase and phase shifted components of the training signal are analyzed, in a digital demodulator (210), so as to detect the IQ-imbalance of the direct conversion receiver (200). The IQ-imbalance is corrected, based on the analysis, in the analogue domain.

    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: The invention relates to a method for correcting an IQ-imbalance (In-phase and Quadrature) of an IQ-based direct conversion receiver (200). In the method a group of radio frequency pilot signals are received in the direct conversion receiver (200). They are conveyed to an in-phase branch and a quadrature-phase branch of the receiver (200) and mixed, in the analogue domain, to form a baseband in-phase (I) and quadrature-phase (Q) signal components. The signal componets are conveyed to a digital demodulator (210) which detects the IQ-phase imbalance of the direct conversion receiver (200) by analysing at least one of the baseband in-phase (I) and the quadrature-phase (Q) signal components. In the method, the detected IQ-imbalance is corrected, in the analogue domain of the direct conversion receiver (200), to achieve a 90 degrees phase difference between a future baseband in-phase (I) signal component and a future baseband quadrature-phase (Q) signal component.
