    Abstract: Provided is a method for simply generating counter block values without additionally transmitting the counter block values. The method for generating a counter block value required by a scrambler or a descrambler includes the steps of : a) setting up a counter of a message to a predetermined initial value, when a counter block to be scrambled or descrambled is in an initial part of the message; b) storing a Common Interleaved Frame (CIF) count value corresponding to the initial part of the message in a buffer, when the counter block to be scrambled or descrambled is in the initial part of the message; c) increasing the counter by a predetermined number; and d) generating the counter block value by using the CIF count value stored in the step b) and the counter increased in the step c).
