摘要： A method and system (100) 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 (100) includes providing a feedback multiplexer (110), a line delay (120) and a feed forward multiplexer (130). The feedback multiplexer (110) has a first input (114), a second input (112) and a first output (116). The first input (114) is for receiving luma data for a current line. The line delay (120) has a delay input (122) and a delay output (124), the delay input (122) coupled with the first output (116). The delay output (124) is coupled with the second input (112). The feed forward multiplexer (130) has a third input (134), a fourth input (132) and a second output (136). The third input (134) is coupled with the delay output (124). The fourth input (132) is for receiving the luma data for the current line. The feedback multiplexer (110) is controlled to provide fedback luma data from the second input (112) to the first output (116) when the current line is the top line and to provide the luma data for the current line from the first input (114) to the first output (116) otherwise. The feed forward multiplexer (130) is controlled to provide next line luma data from the fourth input (132) to the second output (136) when the current line is the bottom line and to provide the luma data from the current line to the second output (136) otherwise.

摘要： A method and system for correcting luma data and chroma data from a composite signal for a plurality of lines are disclosed. The method and system include correlating line data of the composite signal from a portion of the plurality of lines to provide a plurality of correlation signals. The method and system also include generating a chroma suppression signal based on the plurality of correlation signals. The chroma suppression signal indicates whether to suppress a portion of the chroma data. The chroma suppression signal indicates that the portion of the chroma data should be suppressed when a large luma transition and the chroma data being beneath a threshold are detected.
