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。

Abstract: In a color difference conversion system according to the present invention, an input unit receives an image including a color difference meter. A conversion unit increases or decreases a color difference meter bit of the image which is provided from the input unit. An output unit outputs the image, of which the color difference meter bit is increased or decreased by the conversion unit. Therefore, a low quality image can be converted to a high quality image, or a high quality image can be converted to a low quality image.
Abstract translation: 在根据本发明的色差转换系统中，输入单元接收包括色差表的图像。 转换单元增加或减少从输入单元提供的图像的色差计位。 输出单元通过转换单元输出色差表位增加或减小的图像。 因此，低质量图像可以被转换成高质量的图像，或者可以将高质量图像转换为低质量图像。

Abstract: 패킷 필터링 정보 전송 방법 및 장치가 제공된다. 디지털 케이블방송 전송 헤드엔드 내에 위치한 DSG 채널 정보 관리 서버가 케이블방송 수신기에 장착된 케이블모뎀이 수신한 패킷들을 데이터의 종류별로 필터링 할 수 있도록 하는 패킷 주소 및 이와 관련한 정보를 조합하여 하나의 파일로 생성한다. 생성된 파일은 헤드엔드와 케이블모뎀이 상호 지정한 특정 주소 번지를 가진 패킷을 통해 CMTS로부터 케이블모뎀으로 전송되고, 케이블모뎀은 수신한 파일로부터 수신하는 패킷들을 선별하고 필터링할 수 있는 정보를 획득하여 필터를 구성한다. 구성된 각 필터를 통해 선별된 데이터들은 방송 프로그램 정보, 제한수신 관련 정보 등을 처리하는 케이블방송 수신기 내부의 각 처리모듈로 전송된다.
