The invention relates to a storage medium on which a set of data is stored, whereby a first data section of the data set is stored in a read-only memory area and a second data section of the data set is stored in a read/write memory area, and the data set comprises language-independent data and language-dependent data. The data set can be processed in a handling device either in a first processing form related to a first language, or in a different processing form related to a second language. Language-independent data and language-dependent data which are related to the first language are included in the first data section, and language-dependent data which are related to the second language are included in the second data section. For the processing in different form, data from the second data section as well as data from the first data section are to be used.

Storage medium and method for processing data of such storage medium

A magnetic tape apparatus for the recording and reproduction of signals, including a magnetic tape having plural data tracks running parallel to an edge of the tape; a multi-track reading device including a multi-track playback head configured to read simultaneously plural of the tracks and output signals corresponding to data recorded on the plural tracks; and a housing in which the tape and the reading device are permanently disposed; wherein the tape is adapted for simultaneous recording of data onto plural data tracks of the tape via external recording heads upon the apparatus being connected to an external recording facility.

Magnetic tape apparatus with housing in which playback electronics and

Decoder for a frequency keyed signal, particularly an FSK videotext signal. To avoid isochronous distortions, precise matching of the decoder is necessary. Due to the provision of a additional AFC circuit (11) to regulate the natural frequency of the VCO (5) in the PLL loop (3-5) of the decoder, such matching is no longer required.

A digital phase control circuit which includes a controllable oscillator, a programmable divider coupled to the oscillator, a reference frequency source, a phase discriminator coupled to the outputs of the programmable divider and reference frequency source and means coupling the output of the phase discriminator to a control input of the oscillator. In addition to these components, an auxiliary circuit is provided which has its input coupled to the output of the phase discriminator and first and second outputs coupled to the reference frequency source and the programmable divider. The auxiliary circuit generates a first signal at the input of the reference frequency source when the phase difference between the signals at the outputs of the programmable divider and the reference frequency source is in one direction and a second signal at the second input of the programmable divider when the phase difference is in the opposite direction.

Digital phase control circuit including an auxiliary circuit

A circuit arrangement for evaluating a received control signal of the type including a first signal of a first predetermined frequency and of a time duration which represents information, and a second signal which immediately follows the first signal in time and has a second predetermined frequency different than the first frequency. In the circuit arrangement the time duration of the first signal is determined by feeding the oscillations of the first signal to a memory which stores a count representative of the number of received oscillations of the first signal, and serially discharging the contents of the memory upon receipt of the second signal and supplying the contents in series to an output terminal which is connected to the control circuit for evaluating and responding to the information.

Circuit arrangement for evaluating received oscillations of a

A remote control system utilizing an alternating signal, in which the duration of the signal is measured with respect to a time frame composed of a succession of adjacent time groups each subdivided into a succession of adjacent time channels. A first item of information provided by the signal is obtained by observing the time group containing the end of the signal while a second item of information provided by the signal is obtained by observing the time channel within such group containing the end of signal.

Circuit arrangement in a remote control receiver unit for evaluating received remote control signals by counting the number of periods, particularly of ultrasonic oscillations for the remote control of a radio or television set, the arrangement including an oscillator producing oscillations which are utilized for the evaluation, and which have a frequency higher than the frequency of the received oscillations, a counter connected to receive the higher frequency oscillations and to be controlled by the received oscillations so that when the received oscillations are present the counter emits a pulse during each of the received oscillation periods and when no received oscillations are present due to interference, the oscillator oscillations are divided by the counter to the frequency of the received oscillations so that interruptions in the received oscillations have no influence on the subsequent circuit portions.
