to the third inputs thereof whereby the chrominance signal is delivered to the adder means 708 via switch means 737 the inverting means 705b and the third input of switch means 738 the chrominance signal is thus rotated 180 u00b0 on the fourth playback the switch means 738 is stepped to the fourth input whereby the chrominance signal is delivered to adder means 708 via the transversal filter 705 only to provide a 90 u00b0 rotation of the chrominance signal the four fields are combined on successive playbacks via adder means 708 to generate the composite color television signal on terminal 728 the sign of the phase shifting may be changed and the circuit connections and clocks thereto adapted correspondingly whereby on the second playback of the field the transversal filter 705 rotates the chrominance 90 u00b0 and is then coupled to the adder means 708 on the third playback the inverting means 705b rotates the chrominance 180 u00b0 and on the fourth playback the transversal filter 705 provides 90 u00b0 rotation and is coupled to the inverting means 705b which provides 180 u00b0 rotation wherein the combination shifts the chrominance 270 u00b0 thus providng the 90 u00b0 phase shift between playbacks the control means 709 provides the pale clock the four phase clocks the chroma invert enable signal etc to the various components of the inverting means 705c the filter means 701 704 and to the adder means 706 708 as described and shown in the embodiments of the previous figures as well known when a composite color television signal is reconstituted from a single field the horizontal sync pulses are not aligned on successive playbacks without the addition of one half.
