ABSTRACT:
A method for converting video data in a first video format to video data in a second interlaced video format comprising: determining a number of frames of the first video format to map into a frame of the second video format, the frame of the second video format having four fields; determining a number of lines from each of the number of frames of the first video format to be mapped into each of the four fields of the frame of the second video format; selecting the determined number of lines from each of the number of frames of the first video format; determining a sequence for mapping the number of selected lines into the fields of the frame of the second video format; and mapping the selected lines from each of the number frames of the first video format into the four fields of the frame of the second video format according to the determined sequence.
