Abstract: The apparatus and method for scrambling high-rate data is disclosed. The apparatus includes a first storing unit for storing a transport stream (TS) inputted from an external device; a common key (CK) generating unit for generating a CK by receiving a control word (CW) from an external conditional access system (CAS); a key scheduling unit for generating predetermined number of keys (KK)s by receiving the CK from the CK generating unit; a plurality of enciphering units for enciphering the TS transmitted from the first storing unit based on the predetermined number of KKs and the CK; a second storing unit for storing the TS enciphered by the enciphering units and outputting the enciphered TS; and a controlling unit for controlling the multiple enciphering units.

Abstract: A package service management system and method in digital cable broadcasting comprises: a host having middleware for receiving broadcast signals of a headend and bidirectional service information, and executing a package application program for providing a package service; a POD for analyzing data, and decoding a package subscription and termination message using an encoded key so as to allow or disallow watching channels; and a headend for defining package-setting information, transmitting it to the host or the POD, generating entitlement test messages on a paid channel, transmitting them to the POD, and transmitting the subscriber's encoded key according to a request by the POD. Therefore, the subscriber can watch TV and remotely subscribe or terminate a paid package service, thereby increasing user's convenience.
Abstract translation: 一种数字有线广播中的包服务管理系统和方法，包括：具有用于接收头端和双向服务信息的广播信号并执行用于提供包服务的包应用程序的中间件的主机; 用于分析数据的POD，以及使用编码密钥对包订阅和终止消息进行解码以允许或不允许观看频道; 以及用于定义封装设置信息的头端，将其发送到主机或POD，在付费频道上产生授权测试消息，将它们发送到POD，并且根据POD的请求发送订户的编码密钥。 因此，用户可以看电视并远程订阅或终止付费套餐服务，从而增加了用户的便利。
