<p>S01252 S79P147 COLOR VIDEO SIGNAL PROCESSING SYSTEM A PAL color video signal which is reproduced in a special mode, such as a slow, still or fast-forward or reverse mode is re-arranged in order to recover the standard signal sequence of the PAL color television system. In the case of the luminance signal component, two adjacent lines of reproduced video signals are mixed in order to avoid vertical shifting of the reproduced image if the numbers of 2 reproduced field and a reference field are different. In the case of the chrominance signal component, a phase-inversion and/or a signal delay of 1H interval are carried out in order to coincide the chrominance phase sequence of the reproduced PAL color signal with the subcarrier phase sequence which is standard for the PAL color television system. The need for a phase-inversion and/or a signal delay is determined on the basis of an examination of a reproduced color field and a reference color field. -i-</p> |
