ABSTRACT:
A change in field order between an input video frame and an output video frame or an input video frame being displaced by an odd number of scan-lines with respect to an output video frame, may introduce out of order fields in the output video frame. A method (700), apparatus and computer program product for generating an interlaced video stream from one or more interlaced input video streams and graphical objects is disclosed. The method (700) enables input video streams to be transformed (e.g., scaled and translated) to generate an interlaced video stream. The method (700) ensure that the fields of an output video frame are in correct order by shifting a corresponding input video frame down by one scan-line.
