Abstract: 1,225,764. Colour television. BRITISH BROADCASTING CORP. 25 June, 1968 [29 March, 1967], No. 14338/67. Heading H4F. Relates to a PAL colour television system in which the chrominance signals at corresponding points on consecutive lines are represented by F 1  = U 1  + jV 1  and F 2  = U 2  - jV 2  and in which any departure from a line to line conjugate relationship of F 1  and F 2  due to phase distortion # is compensated by combining an errorcorrecting signal with the chrominance signal F 2  in an addition circuit 15. Since changes in colour detail in the vertical direction also result in a departure from the line to line conjugate relationship, such changes will also be processed as if they were due to phase distortion and the present invention is based on the realization that the amount of phase correction which need be applied can be limited to the maximum phase distortion #max likely to occur, e.g. #max = 25 degrees, the correcting signal being suppressed for any phase " errors " exceeding #max on the assumption that such " errors " are due to true colour changes. As described, the correction signal is suppressed when: where k = S 1 /S 2 , S 1  = |F 1 | , S 2 = |F 2 | and x  and y are preset constants, e.g. x = 1À4, y = 0À7. As shown simultaneous signals U 1  - jV 1  and - U 2  + jV 2  derived from the sequential signals F 1  and F 2  are combined in an addition circuit 12 to give the correction signal e which is applied to the addition circuit 15 (for combination with F 2 ) through a normally open gate 14 which is inhibited by a control signal from the k and r unit 18 when condition (1) or (2) above occurs. Fig. 2b (not shown) gives the block diagram of the unit 18, each k and r component comprising a balanced demodulator and logarithmic comparator (circuit details, Fig. 3, not shown).
