摘要： PURPOSE: A downloadable conditional access system server, a digital multimedia broadcasting terminal, and a method for providing downloadable conditional access system service are provided to offer a DCAS solution using a DMB net and a mobile radio communication network. CONSTITUTION: A message transfer part(311) transmits a DCAS message including the DCAS information through a first data channel to a DMB terminal. An image transmitting portion(312) transmits the common conditional access client image through a second data channel to the DMB terminal. The DMB terminal requests the personalization information related through a mobile communication channel to the operation of the common conditional access client image. An information transfer part(313) processes the authentication about the DMB terminal. The information transfer part transmits the personalization information through the mobile communication channel to the DMB terminal.

摘要： An apparatus and a method for reassembling a DOCSIS(Data-Over-Cable Service Interface Specifications) MAC(Media Access Control) frame in a cable modem having a plurality of receiving channels are provided to reassemble a DOCSIS MAC frame by extracting the DOCSIS MAC frame from MPEG2-TS packets. Downlink channel receiving modules(111,112) receive a RF signal, and outputs a MPEG2-TS packet signal. MAC frame reassembling buffer writing modules(121,122) store data to MAC frame reassembling buffers(141,142). MAC reassembling control modules(131,132) control a MPEG header and a point field. MAC frame reassembling butter reading modules(151,152) store one complete DOCSIS MAC frame to a MAC frame buffer. MAC frame buffer modules(161,162) store one complete DOCSIS MAC frame.
摘要翻译：提供了一种用于重新组装具有多个接收信道的电缆调制解调器中的DOCSIS（数据有线服务接口规范）MAC（媒体访问控制）帧的装置和方法，以通过提取DOCSIS MAC帧来重新组合DOCSIS MAC帧来自MPEG2-TS数据包。下行链路信道接收模块（111,112）接收RF信号，并输出MPEG2-TS分组信号。 MAC帧重组缓冲器写入模块（121,122）将数据存储到MAC帧重组缓冲器（141,142）。 MAC重组控制模块（131,132）控制MPEG头部和点域。重新组合黄油阅读模块（151,152）的MAC帧将一个完整的DOCSIS MAC帧存储到MAC帧缓冲器。 MAC帧缓冲器模块（161,162）存储一个完整的DOCSIS MAC帧。
