Abstract

The error detecting method involves dummy codes being provided at a transmitter in a frame instead of the information signals if there is no information signal in the frame. Attribute flags are provided at the signal transmitter for informing attributions of the information signals and dummy codes. A check code is provided at the transmitter checking errors of attribute flags and information signals excluding attribute flags for the dummy codes and dummy codes. - A second check code is provided at the receiver by using received information signals, the dummy codes and attribute flags in the first frame. The second code checks errors of attribute flags and information signals, excluding attribute flags for the dummy codes and the dummy codes.
