DISPLAYING TV SET Russian patent published in 1997 - IPC

FIELD: radio engineering, in particular, receiving TV programs in meter and decimeter bandwidth, display for home and personal computers. SUBSTANCE: device has two antenna inputs which are connected to corresponding channel selectors 2.1 and 2.2. channel selector 2.1 is connected to input of radio channel unit 2.3, which output is connected to joined inputs of selectors 2.1 and 2.2, which are connected to also to output of program selector 4. Second output of radio channel unit 2.3 is connected to input of low-frequency amplifier 1.1, which output is connected to dynamic head. Video output of unit 2.3 is connected to input of video signal interface unit 2.3, which output is connected to corresponding inputs of line scanning unit 5, frame scanning unit 7 and video amplifier 8. Outputs of frame and line scanning units 7 and 5 are connected to inputs of dynamic focusing unit 6, which output is connected to input of kinescope 10. Output of video amplifier is connected to second input of kinescope 10. Line scanning unit 5 not only generates deviation line sweeping current but also outputs high-voltage anode voltage for operations of kinescope 10, stepping-up voltage for power supply of video amplifier 8, power supply of variable capacitors 9, dynamic focusing unit 6. Voltage which has been stabilized in power supply of variable capacitors 9 is sent to program selector 4. Suppression pulse generator 11 is connected to modulator of kinescope 10. Second input of suppression pulse generator 11 is connected to output of frame scanning unit 7. Third output of suppression pulse generator 11 is connected to output of line scanning unit 5. EFFECT: increased functional capabilities. 4 dwg
