摘要： A picture flicker correction is desired with video disc players involving display of a stop-motion or still television picture and with television displays using field and line frequency doubling, in accordance with the so-called ABAB method. With a movement detector (51) movement or the absence of movement is detected. Two adding circuits (19, 22) are connected in parallel to delay devices (9, 9+12) having time delays substantially equal to a field period. By means of two switch-over devices (32, 37) switched by the movement detector (51), the delay devices (9, 9+12) or the adding circuits (19, 22) can be coupled with a switch-over device (45) which is switched once per field period. A further delay device (42) having a time delay substantially equal to a field period provides for information transfer during second field periods of frame periods comprising two field periods. In the absence of movement detection, the original information is transferred, and in the event of movement detection, the combined information is transferred.

摘要： A color television Y/U/V luminance-chrominance multiplex signal with signals which may or may not be compressed in time comprises for a television line the associated luminance information Y and half the chrominance information U or V. As a result the circuit should supply the chrominance information directly (U, V) and repeatedly (U', V') during a subsequent television line. To avoid the use of an accurate, expensive delay device having a line period delay, the circuit includes an input shift register (A) of the series-in, parallel-out type, which is coupled through an on-off switch circuit (B1, B2) to parallel inputs of two shift registers (C1, C2) of the parallel-in, series-out type. During a line blanking period (THB) writing is effected from the input shift register in the output shift registers and during two subsequent line scan periods (THS1, THS2) reading is effected consecutively therefrom. Reading may be effected in opposite phase if a repetition is to be effected after exactly one line period.
