Title: Television receiver with digital signal processing having a digital-to-analog converter control capability
IPC: H04N9/64
Filed: 1983-07-22
Abstract: In a television receiver with digital signal processing circuitry, a composite video signal is sampled by an analog-to-digital converter. A luminance processor responsive to the digital samples of the composite video signal develops digital luminance signals and a chrominance processor develops digital chrominance signals. A digital-to-analog converter coupled to the luminance and chrominance processors develops a plurality of analog output voltages representative of the luminance and chrominance information. A driver circuit converts the analog output voltages to drive signals that are applied to the cathode electrodes of a color picture tube to produce a display of the picture information contained in the composite video signal. A signal generator develops a control signal that is applied to a reset line of the digital-to-analog converter to establish the analog output voltages at predetermined levels. If the control signal, for example, is indicative of the blanking interval within the composite video signal, the predetermined levels established are ones that will produce a blank display.
