    • PURPOSE: An entitlement control message inserting apparatus for digital broadcasting and an entitlement control message extracting apparatus for digital broadcasting receivers are provided to search an entitlement control message rapidly and simply in the digital broadcasting receiver by transmitting position information to the digital broadcasting receiver. CONSTITUTION: An ECM(Entitlement Control Message) insertion part(120) inserts an entitlement control message into an insertion location of the entitlement control message selected by an ECM insertion selection part(110). A location information insertion location selector(130) selects the insertion location of location information indicating insertion location of the selected entitlement control message. A location information insertion part(140) inserts the location information to the selected insertion location.

    • PURPOSE: A conditional access system(CAS) authentication method using a TV idle bandwidth is provided to enable only authenticated user to install or delete a CAS application, thereby receiving a desired broadcasting service without replacement of a set-top box. CONSTITUTION: A broadcasting company(600) transmits a public key to a receiving terminal through an idle bandwidth(800) after authenticating a CAS application. The receiving terminal delivers the public key for the CAS application to the broadcasting company. The broadcasting company transmits an encoded operation key to a set-top box(700) through the idle bandwidth The set-top box transmits a decoded operation key to the broadcasting company. When just permission for the receiving terminal is existed, the receiving terminal receives data.
