Patent ES-486553-A1 (ES)
Title: Video processing system including comb filters
IPC: H04N9/85
Filed: 1979-12-03
Abstract: In a video processing system including comb filters for separating interleaved luminance and chrominance components, the time of occurrence of the color synchronizing component of the composite color video signal is detected after the comb filtering and separating of the luminance and chrominance components. The composite signal components include spurious frequency variations which accompany the composite signal during playback from a video disc. A first phase locked loop coupled to a frequency translator is used to remove the spurious frequency variations from the separated and frequency translated chrominance components. A second phase locked loop is connected between a second frequency translator and a clock controlled delay line. The second phase locked loop tracks the spurious frequency variations in a manner to assure that accurate combing of the component signals occurs at the output of the comb filters. The same reference frequency is used in the first phase locked loop as well as in the second frequency translator.

Title: High voltage dynamic focusing system
IPC: G09G1/00
Filed: 1985-01-29
Abstract: A C.R.T. display system 10 has a dynamic focus circuit 86 to compensate for the inherent defocussing of a beam from an electron gun 20 on to a display screen 16. Circuit 86 receives a variable focusing signal 88 of bandwidth from zero to a predetermined frequency and includes a network 110 combining a reference voltage from the anode supply 28, a first portion of the applied focusing signal amplified 98 and coupled via capacitor 108, and a second portion of the applied signal amplified 100, to produce at focus electrode 24 a composite focusing signal 19 which has a nominal focusing voltage level which focuses the beam at the screen center 82. The balancing circuit 102 attenuates this level at the output of the amplifier 100. The circuit 86 has a substantially uniform transfer function relating the applied signal 88 to the composite focusing signal 19 that is frequency independent over the bandwidth of the applied signal so that the composite focusing signal 19 provides accurate focusing both when the beam is fixed off-center or moving.
