摘要： In an automatic gain control unit, the gain of a voltage-controlled amplifier (VCA) (25) is regulated with a closed-loop control circuit. The time constant of the control circuit is varied dependent on the magnitude (31) of the VCA output signal. As long as the magnitude (31) of the VCA output signal is small, the gain is slowly adjusted. In case the magnitude (31) of the VCA becomes so large that saturation of the analog-digital converter (28) might occur, the time constant of the control circuit is decreased, in order to allow for a quick adjustment of the amplifier's gain.

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： 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.
摘要翻译：在数字广播系统中，除了主要业务外还广播新闻服务等附加服务。通常，这些附加服务由服务提供商（3）定期更新和广播，每天多次。为了使接收服务的接收设备（1）中的附加服务发送的服务数据保持最新，给出接入服务的方法，根据该方法，服务提供商（3）提供的服务的相应服务信息是从接收设备（1）当前接收到的服务提取，然后可以访问根据相应提取的服务信息提取服务信息的服务中的至少一个。因此，即使在诸如更新率的附加服务的传输条件随时间变化，服务数据也可以由接收设备（1）自身自动更新。
