摘要： A combined de-interlacing and frame doubling system (114, 114' and 114'') advantageously serves to de-interlace successive lines of Present Field Video data at twice the field rate to yield an output bit stream suitable for display on display device that utilizes progressive scanning. The de-interlacing and frame doubling system in accordance with present principles includes a frame memory mechanism (116, 116' and 116'') for storing at least one frame of interlaced video having a prescribed field rate. At least one de-interlacing circuit (11401, 1140'1, 1140'') pulls at least two fields of video data from the memory mechanism at a rate of at least twice the field rate for performing a full de-interlacing function in half of a field period to generate the a progressive, frame doubled signal for receipt at the display device.

摘要： A method (500) of converting interlaced video to progressive video includes receiving a video signal (505) representative of at least one picture and determining whether the at least one picture is progressive (510). Responsive to the progressive picture determination, a vertical synchronization signal is selectively modified to identify whether a field previously sent and a field to immediately follow are from a same progressive picture (615, 640).

摘要： A method (300) of converting interlaced video (Fig. 2A) to progressive video can include a series of steps. The method can include receiving a video signal (310) representative of at least one picture and determining (320) whether the picture is progressive. If the picture is progressive, a vertical synchronization signal is modified to create an association with a first field of the picture (340). Accordingly, a progressive video signal can be converted to an interlaced video signal associated with the vertical synchronization signal and the interlaced video signal can then be converted to a progressive video signal in correspondence with modification made to the vertical synchronization signal (350).
