    Abstract: A method for recording information that is transmitted over a radio frequency, especially traffic information, in which, in a monitoring state, the receiving device is supplied with power in a clocked manner. While switched on, the receiving device is tuned to a preestablished radio frequency and the received radio frequency is monitored for the presence of an identifier designating information. In the event an information identifier is detected, the receiver is supplied with power for the duration of the identifier and the information is recorded. In response to switching on the monitoring state, the preestablished radio frequency is determined as the frequency to which a radio frequency refers that transmits no information and that was set before the monitoring state was switched on.

    Abstract: A bit timing signal is regenerated from an encoded digital signal in a receiver using a predetermined sample rate Fs. An input pulse signal is generated in response to predetermined transitions of the encoded digital signal. A clock count signal is generated having a variable clock period according to cyclical counting of the clock count signal up to a count value S at the predetermined sample rate, the count value alternating between an upper value Su and a lower value Sl so that the variable clock period has an average length substantially equal to a data bit period of the encoded digital signal. The clock count signal is synchronized with the encoded digital signal by 1) counting the input pulse signals to generate a pulse count, 2) counting sampling periods between successive input pulse signals to generate a sample count, and 3) generating a sync signal if the pulse count is greater than a pulse threshold and the sample count is greater than a sample threshold. The clock count signal and the pulse count are reset in response to the sync signal.

To enhance efficiency in data processing and use of storage capacity, transmitter related data including tuning data is stored separately from program related RDS data. Per each detected transmitter a permanency factor indicating the permanency in reception quality thereof is being allocated to each detected RDS transmitter and stored in a first memory bank, along with the relevant tuning data. Per each program identification code carried in the RDS data of the so detected transmitters program related FM RDS data are being stored in a second memorybank, a linkage code defining the storage address within the second memory bank containing the program data carried by the relevant FM RDS transmitter being allocated to the transmitter data of each FM RDS transmitter and stored in the first memory bank.
