Bit-Error refers to the amount of interference and interruptions in reception, you can use this figure together with the Signal Strength to understand how good your reception can be. Bit Error Rate should be low and Signal Strength should be high for a good picture.
The causes of the corruption are several, like a very strong signal being one of them, corrupt data due to low signal level and/or due to interface corruption of the signal, noise in the signal from bad weather or lightning, cross-modulation of the signal from high trees, hills or buildings obstructing the aerial. These figures are generally to do with your location and the positioning and type of aerial.
