METHOD AND APPARATUS FOR PROCESSING OF BROADCAST DATA

摘要

A plurality of conditional access (CA) clients are needed to receive services from a plurality of service, where the CA clients respectively correspond to the service providers. Thus, the CA clients should be installed into a broadcast receiver, and in this case, a method of managing the CA clients is needed. Provided are a method and apparatus for processing broadcast data by using a security client. The method includes determining a first security client based on a security client list, where the first security client is used to decrypt encrypted broadcast data and the security client list comprises information regarding each of security clients available which provide information necessary to decrypt the encrypted broadcast data; and decrypting the encrypted broadcast data by using the first security client. Accordingly, it is possible to allow a user to receive various services.
