摘要： Television receiver with a receiving section, a circuit for processing a received television signal which preferably contains digital data, whereby the circuit has a selection stage (4, 5), and a measuring circuit (9), which has an output (8), for measuring the signal quality or a measured variable representative for that (quality) like, e.g., signal-to-noise ratio, field intensity, bit error rate, etc, of the received television signal. The selection stage (4, 5) possesses a controllable transmission band (range) and has a control input (6, 7). The control input of the selection stage is connected with the output (8) of the measuring circuit (9). The measuring circuit controls the transmission band of the selection stage depending on the measured signal quality in such a way that upon worsening/improving of the signal quality of the received television signal, transmission band of the selection stage is reduced/increased.

摘要： Within a television receiver adapted for MAC reception and including a PIP processor in case the MAC signal is fed to the PIP processor a MAC decoder is needed as the PIP processor can handle only the composite PAL video signal. It is an object to simplify the circuit means in case of PIP display of a MAC signal. According to the invention switching means S3 are provided for connecting the input of the PIP processor to the output of a PAL encoder which is provided for furnishing output signals for a video tape recorder. Especially for a colour television receiver designed for MAC reception and PIP display.

摘要： Television receivers for microwave reception, for instance for reception of transmissions from earth satellites, are required to operate with a large number of different antenna assemblies from various manufacturers and which require different operating voltages. It is an object of the patent to modify the receiver in such a way that it can supply the appropriate operating voltages to the antenna assemblies in a simple way.

摘要： Within data processing systems, for example in the NICAM decoder of a television receiver, data signals on a plurality of input lines have to be read and fed sequentially to a serial data bus. Normally for this purpose expensive integrated circuits with several inputs and ouputs are needed. It is an object of the invention to simplify this operation and to use a bus device which is less expensive than devices used up to now. A device having outputs only (for example OP1, OP2) is used for reading the said input lines sequentially. This is achieved by a diode/resistor matrix which is connected between each data input L1, L2, the outputs OP1, OP2 and the common DATA READ line RL. Thus an inexpensive device or devices having outputs only can be used for sequentially reading signals from a number of input lines.

摘要： Automatic switching circuitry (1) comprises means to process input signals of more than one frequency incorporating information for the derivation of one or more audio channels. The processing means includes selectively variable bandpass means (11, 12) which may be one of several values corresponding to the frequency of an input signal. Means (14) are provided to apply a demultiplex operation on signals output from the bandpass means (11, 12). Control logic (15) monitor the demultiplex means (14) to determine if a demultiplex operation has been achieved and instruct selection of another value for the bandpass means (11, 12) if no demultiplex operation was achieved for a given value of the bandpass means (11, 12).
