摘要： Television systems comprising tuners (1), controllers (2) for controlling tuners (1), and stages (3) for receiving tuned signals from tuners (1) and for supplying control signals to controllers (2), use time-consuming automatic fine tuning signals while high speed tuning. By using lock signals (53) from phase-locked-loops (31) in stages (3) as control signals, an indication whether a channel is active or not can now be got much quicker due to lock signals being much faster available than automatic fine tuning signals. By using synchronization signals (54) from synchronization generators (4) as further control signals, a further indication is got. In a fast tuning mode, frequencies nearby active channels are detected, and in a fine tuning mode, channel frequencies are identified. According to the basic idea, lock signals originating from phase-locked-loops (31) in stages (3) can give first indications whether a channel is active or not, preferably and further advantageously in combination with second indications based upon synchronization signals (54).

摘要： A television apparatus (100) is switchable to a radio receiver mode. The radio signal is processed in a picture processing path of the television apparatus, transformed to a predetermined auxiliary intermediate radio carrier frequency (f IR ) within the picture pass band of the picture processing path, such that the relationship f IR = f ref,i - f D is satisfied, f ref,i being an intrinsic reference frequency of a PLL reference signal generator, and f¿D? being the frequency distance between a predetermined intermediate picture carrier frequency (f IP ) and a predetermined intermediate sound carrier frequency (f IS ) for television signals.

摘要： The display device has a cathode ray tube (T), which has an electron gun (G) for generating an electron beam and an outer conductive layer (AD). A video processing circuitry (VP) provides a video signal (Vo) having a black level (BLR, BLG, BLB) to a video amplifier (VA) for modulating the electron beam. The video processing circuitry (VP) has black level controlling circuitry (BL) for controlling the black level (BLR, BLG, BLB) of the video signal (Vo). A sensing circuit (S) senses a black current level of the electron beam corresponding to the black level of the video signal (Vo) and feeds back information about the black current level to the black level controlling circuitry (BL) for stabilizing the black current level. The sensing circuit (S) is coupled to a node (X) to which the outer conductive layer (AD) and one of the output terminals of a high-tension generator (H) are coupled.

摘要： A multi-channel receiver (200) comprises: an input (111) for receiving a wideband signal potentially comprising multiple channels, a tuner stage (110), a wideband amplifier (201) connected between the input (111) and the tuner (110), a controllable switch (202) bridging the amplifier (201) and a switch controller (203) designed to generate a switch control signal (BSC). For controlling the switch, the switch controller (203) is designed to measure at least one signal quality parameter and to generate its switch control signal (BSC) on the basis of the measured parameter. The decision of switching the switch (202) to its open state (amplifier active) is exclusively taken during at least one time interval when the receiver is switched to a channel.
