A method and system for performing combing for PAL luma data is disclosed. The combing is performed for a display having a plurality of lines. The display is capable of depicting a frame including a horizontal boundary having a top edge and a bottom edge. A top line of the plurality of lines is at the top edge of the horizontal boundary. A bottom line of the plurality of lines is at the bottom edge of the horizontal boundary. The method and system includes providing a feedback multiplexer, a line delay and a feed forward multiplexer. The feedback multiplexer has a first input, a second input and a first output. The first input is for receiving luma data for a current line. The line delay has a delay input and a delay output, the delay input coupled with the first output. The delay output is coupled with the second input. The feed forward multiplexer has a third input, a fourth input and a second output. The third input is coupled with the delay output. The fourth input is for receiving the luma data for the current line. The feedback multiplexer is controlled to provide fedback luma data from the second input to the first output when the current line is the top line and to provide the luma data for the current line from the first input to the first output otherwise. The feed forward multiplexer is controlled to provide next line luma data from the fourth input to the second output when the current line is the bottom line and to provide the luma data from the current line to the second output otherwise.
