摘要： A method of recording scrambled digital data comprising the steps consisting in: (a) receiving a scrambled digital data stream; (b) identifying in the data stream a control packet (ECM) containing at least one key (CW) for descrambling at least a part of the data of the stream; (c) storing the control packet in a table; and (d) recording the data stream and the said table on a data storage medium. A storage medium and a method of reading the recorded data are also proposed.
摘要翻译：一种记录加密数字数据的方法，包括以下步骤：（a）接收加密的数字数据流; （b）在数据流中识别包含用于解扰流的数据的至少一部分的至少一个密钥（CW）的控制分组（ECM）（c）将所述控制分组存储在表中; 和（d）将数据流和所述表记录在数据存储介质上。还提出了存储介质和读取记录数据的方法。

摘要： A video signal processing system, such as a pay TV system, that includes a smart card access control feature decodes control information from data included in groups of video line intervals that represent data channels. Each channel includes data arranged in packets of data. Each packet includes both descriptor data and application data. The packets of data are extracted from the video lines by a data dispatcher. After receiving a packet from a data channel, the data dispatcher analyses the descriptor data to determine the target for the application data. The data dispatcher transmits the application data contained in the packet, without analyzing the data, to the correct target processor unit, e.g. either a control access processor or a decoder intelligent processor. Information that may be transferred to the decoder processor includes, a specific channel allocation table, data related to the VTR of the customer, and information related to a geographic location.
摘要翻译：包括智能卡访问控制特征的诸如付费电视系统的视频信号处理系统从表示数据信道的视频行间隔组中包括的数据解码控制信息。每个通道包括以数据包排列的数据。每个数据包都包含描述符数据和应用数据。通过数据调度器从视频行中提取数据包。在从数据通道接收到数据包之后，数据分派器分析描述符数据以确定应用数据的目标。数据调度器将包含在分组中的应用数据传送到正确的目标处理器单元，例如，不分析数据。控制访问处理器或解码器智能处理器。可以传送到解码器处理器的信息包括特定信道分配表，与客户的VTR有关的数据以及与地理位置有关的信息。

摘要： In a system for controlling access to signals such as pay-TV signals, the signals include data packets that are received and by a decoder and forwarded to a smart card for access authorization processing. The data packets contain information that updates entitlement or access authorization data inside the smart card. Time-related data is added to the data packets. The smart card checks to determine if the time-related data evolves between two successive packets. If not, the smart card inhibits the delivering of descrambling parameters to the decoder.
摘要翻译：在用于控制对诸如付费电视信号的信号的访问的系统中，信号包括被接收的数据分组，并由解码器转发到智能卡进行访问授权处理。数据包包含更新智能卡内的权限或访问授权数据的信息。时间相关数据被添加到数据包中。智能卡检查以确定时间相关数据是否在两个连续数据包之间发展。如果不是，则智能卡禁止向解码器传送解扰参数。

摘要： A subscriber/user TV system operates in response to locally stored entitlements. A user gains access to a program only if the description of the program is consistent with entitled rights owned by the user. Each night at a given hour, decoders affiliated with the system tune to a predetermined video or audio channel, a so-called Barker channel. Decoders previously in a stand-by mode are activated in order to tune to the Barker channel. The program provider then sends the entitlement data on the Barker channel while every affiliated decoder is responsive to an incoming data stream.
摘要翻译：用户/用户电视系统响应于本地存储的权利而操作。仅当程序的描述与用户拥有的权利权利一致时，用户才能访问程序。每个晚上在某一小时，附属于系统的解码器调到预定的视频或音频通道，即所谓的巴克通道。先前处于待机模式的解码器被激活，以调谐到巴克通道。程序提供商然后在巴克信道上发送授权数据，而每个附属解码器响应于输入数据流。
