- Hanover_bars abstract "Hanover bars, in the simplest PAL television video format, are an undesirable artifact in the reception of a television image.Two signals, B-Y (U) and R-Y (V) are used in the PAL system to carry the color information for a picture, with the phase of the V signal (hue) reversed (i.e. shifted through 180 degrees) on alternate lines (hence the name PAL, or phase alternate line). This is done to cancel minor phase errors in the reception process. However, if gross errors occur, complementary errors from the V signal carry into the U signal, and thus stripes occur.Later PAL systems introduced alterations to ensure that Hanover bars do not occur, introducing a \"swinging burst\" to the color synchronization. Other PAL systems may handle this problem differently.".
