pub type NUM_LINES_R = FieldReader<u16, u16>;

Field num_lines reader - Specify the total number of lines in a video frame. 11 bits unsigned integer. Allowed range is 0 to 2048. For interlaced video: When NTSC, and FirstVideoLine is greater than 20, then NumLines is restricted to be greater than 2*(FirstVideoLine+18).

When NTSC, and FirstVideoLine is not greater than 20, then NumLines is restricted to be greater than 77. When PAL, and FirstVideoLine is greater than 22, then NumLines is restricted to be greater than 2*(FirstVideoLine+18). When PAL, and FirstVideoLine is not greater than 22, then NumLines is restricted to be greater than 81.
