摘要： In digital broadcast systems, it is common to broadcast besides main services additional services like news services. Typically, these additional services are regularly updated and broadcasted by a service provider (3) several times a day. In order to keep service data transmitted by the additional services up to date in a receiving device (1) receiving the services, a method of accessing services is given according to which a respective service information about the services provided by service providers (3) is extracted from a service presently received by the receiving device (1), and then at least one of the services about which service information was extracted according to the respective extracted service information might be accessed. Thus, the service data can automatically be updated by the receiving device (1) itself, even if transmission conditions of an additional service like update rates change over the time.

摘要： A radio transmission signal consisting of signal frames that comprise a dynamic data part and a quasi-static data part according to the present invention is characterized in that the dynamic data part of a respective frame contains an indicator showing in which following frame the quasi-static data part of this respective frame will be repeated. Therewith, an alternative frequency of e.g. a digital shortwave signal like a DRM signal can easily and satisfactorily be checked before a fast seamless switching to this alternative frequency can be performed. The inventive method to perform a seamless switching of a receiver from a first currently tuned frequency to a second alternative frequency is characterized by the step of receiving at least one set of samples from a respective signal transmitted on at least one second frequency during a time period during which said indicator assures that it is secure that only data that has been transmitted at least once is transmitted as signal on said first frequency to gather some information about said alternative frequency.

摘要： An alternative frequency of e. g. a digital shortwave signal like a DRM signal can easily and satisfactorily be checked whether or not the same service is transmitted before a fast seamless switching to this alternative frequency can be performed. The inventive method to perform such a checking is characterized by a respective correlation of at least two sets of samples taken from the signal transmitted on the alternative frequency having a predetermined time relationship (&Dgr;tcorr) and a comparison of said respective correlation results, i.e. comparison of the time (t1) of occurance of a correlation peak included in a first correlation result with the time (t2) of occurance of a correlation peak included in a respective further correlation result, to verify that both services are the same when the time relationship (|t2 l -t1|) between said correlation peaks is the same as said predetermined time relationship (&Dgr;tcorr) of the at least two sets of samples.

摘要： The common-wave broadcasting of radio programs is known in the art. Common-wave operation of radio transmitters allows the available transmission band width to be particularly well utilized, for example for national scale common-wave broadcasts. A new process now allows a stereo transmission channel to be divided into two mono transmission channels during radio broadcasts and to broadcast certain programs only through particular transmitters. Information concerning the division of the stereo transmission channel into two mono transmission channels is further broadcast over the entire common-wave transmission network. This information causes receivers tuned to this transmission channel to automatically switch to mono evaluation of the reception signal. On a regional level, information may also be broadcast concerning which of both mono transmission channels may be received. Alternatively, the receiver or user himself may select the mono transmission channel he wishes to receive. This process may be implemented with all common-wave broadcasting modes.

摘要： A transmitting device, a receiving device, and a communication method are for transmitting and receiving data modulated on frequency subcarriers of an OFDM communication system. An OFDM burst includes a preamble part and payload data part, whereby the preamble includes a section of pilot symbols mapped onto every n-th frequency subcarrier and signaling data mapped onto the frequency subcarriers between the frequency subcarriers with the pilot symbols. A first channel estimation on the basis of the received pilot symbols is performed, the result of which is used to reconstruct the entire section of the received preamble as a training pattern for an accurate channel estimation, which is used for a channel equalization of the received payload part.
