Title: Improvements relating to colour television apparatus
Inventor: COOPER VICTOR JAMES
IPC: H04N9/72
Filed: 1955-04-29
Abstract: 782,461. Colour television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 30, 1956 [April 29, 1955], No. 12424/55. Class 40 (3). In colour television apparatus employing a signal of the colour subcarrier type and in which a subcarrier synchronizing " burst " occurs during the back porch following the line synchronizing pulse, a D.C. restorer circuit comprises a conventional diode restorer 2 connected to the grid of an amplifier 3, through which the video signals pass, together with a four-diode gate 10 which is arranged to sample the output of the amplifier for a period during the back porch and apply back a correcting potential to the amplifier grid. The input to gate 10 is derived via cathode follower 6 and the correcting potential output is applied via a further cathode follower 11. During the periods between sampling, the correcting potential persists since the leakage of voltage from the capacitance at grid of cathode follower 11 is negligible when the gate 10 is open. Pulses to control gate 10 are derived by separating positive-going sync. pulses from a video signal input at 31 in separator stage 32 and applying them to a short-circuited delay line 35. The combination of original and reflected pulses at a tap 36 results in a pair of oppositely-poled pulses of reduced duration (3 micro-seconds) for each sync. pulse. The second pulse of each pair, which is of positive polarity and may be arranged to occur a short while, for example, half a microsecond, after the sync. pulse termination, is selected by a valve 37 and applied to a phase splitter stage 38 to derive positive and negative pulses to control gate 10. If desired, A.C. coupling may be provided between amplifier 3 and cathode follower 6 provided the time-constant of the coupling is large compared with any unwanted variation it is desired to correct. In a modification, Fig. 2 (not shown), the coupling between the amplifier and cathode follower comprises a series combination of gas discharge tubes and a valve, the signal to the cathode follower being taken from across the valve. The gas discharge tubes present a high D.C. resistance and low A.C. resistance whereas the valve presents a low D.C. resistance and high A.C. resistance. Consequently only a small part of the D.C. voltage due to the coupling is applied to the cathode follower but a very large proportion of any A.C. voltage including variations it is desired to correct. A stage of D.C. amplification may be included in the feed-back loop.
