Patent number: 8134641Abstract: Methods and apparatuses for processing a video signal are provided, in which a video signal for an interlaced scanning mode is received that has a first field and a second field. Further, a determination is performed as to whether the first field and the second field are inverted with respect to each other, and the first field and the second field are recovered if the first field and the second field are determined to be inverted with respect to each other. Thus, a video signal can be generated for a progressive scanning mode on the basis of the recovered first and second fields. Thus, an odd field can be correctly distinguished from an even field, which are included in a video signal for an interlaced scanning mode.Type: GrantFiled: July 17, 2006Date of Patent: March 13, 2012Assignee: Samsung Electronics Co., Ltd.Inventor: Young-hun Choi
