11 Interlaced video divides an image into two fields, containing only the
14 fields a cathode ray TV displays the lines interleaved, yielding the
17 fields reduces the flicker without the necessity of doubling the frame

22 fields are in fact captured at two different instances in time. An

47 In V4L it is assumed that all video cameras transmit fields on the media
101 - Images contain both fields, interleaved line by line. The temporal
102 order of the fields (whether the top or bottom field is older)
108 - Images contain both fields, the top field lines are stored first
111 memory. Image sizes refer to the frame, not fields.
114 - Images contain both fields, the bottom field lines are stored
117 memory. Image sizes refer to the frame, not fields.
120 - The two fields of a frame are passed in separate buffers, in
126 fields pair to build a frame. If fields are successive, without
127 any dropped fields between them (fields can drop individually),
135 - Images contain both fields, interleaved line by line, top field
