Receiver for receiving analog and digital broadcast programmes, selecting the analog broadcast programme which corresponds to the digital programme when reception of the digital signal is no longer possible

摘要

there is a receiver for analog and digitally transmitted broadcast programmes proposed, which serves to a currently tuned radio programme equivalent radio programme automatically switch if a signal quality of the radio broadcasting and now posted ter, a threshold is lowered.furthermore, automatically from an analog radio programme at the time is set to a digital broadcast radio programme using, if the signal quality of the digital radio broadcasting over a first threshold value is assigned.the erfindungsgemu00e4u00dfe receiver has an antenna (1), a hochfrequenzempfangsteil (2) and a processor (3) for receiving analog and digital rundfunksignalen. the measurement of the radio programme at the moment for short periods equivalent programmes carried out with no audible effects.as expected signalparameter the rundfunksignale different parameter (e.g., the signalfeldstu00e4rke and basisbandenergie). different signalparameter to estimate the signal quality of a radio broadcasting used these different signalparameter weighted sum is formed and the sum is compared with schwellwerten.alternatively, a majority vote is carried out.
