    • Sequential/interlace scan conversion of NTSC or PAL color television signals is effected by an encoder the output of which is connected to the input of scan conversion apparatus. Controllable phase shift means is included in either the color signal input or the subcarrier input of the encoder and is adapted to vary the phase of the modulated subcarrier for each line of the received color signal by an essentially integral number of quarter cycles in dependence upon the line number. The control is such that the conversion apparatus provides an encoded output signal with the color subcarrier in PAL or NTSC format. The invention can also be used in converting between different types of interlace systems.
    • NTSC或PAL彩色电视信号的顺序/隔行扫描转换由编码器实现,该编码器的输出连接到扫描转换装置的输入端。 可控相移装置被包括在编码器的彩色信号输入端或子载波输入端中,并且适于根据接收到的彩色信号的基本上整数倍的四分之一周期来改变接收到的彩色信号的每一行的调制子载波的相位 电话号码。 该控制使得转换装置以PAL或NTSC格式提供具有彩色副载波的编码输出信号。 本发明还可以用于不同类型的交错系统之间的转换。
