The DVB Common Interface specifications CENELEC EN 50221 and ETSI TS 101 699 describe a system whereby a removable Conditional Access CICAM, given the appropriate rights, unscrambles protected content and routes it back to the Host over the same interface. The DVB Common Interface specifications were extended by the CI Plus specification v1.3.2, developed by CI Plus LLP, which provides common methods (i.e. methods that are independent of the up-stream CA system) for mutual authentication of the CICAM and Host, and link encryption over the return interface from the CICAM to the Host. TS 103205 specifies extensions to the CI Plus V1.3.2 specification.

Canal Digital is the umbrella term for the different specs for all North European Countries (Scandinavia), i.e. Denmark , Sweden, Finland and Norway(丹麦，瑞典，芬兰，挪威). It covers reception parameters and software regulations for DVB-S2, T2 and C. and has several subspecies called Nordic, Boxer etc. issued by national providers, but all relating to the major spec, the general procedure is similar to M7 Group

This document is intended to Service Operators making use of the CI Plus technology and intending to enforce revocation on their network. The document provides guidance on how to constitute a revocation carousel and how to signal it, making use of predefined CI Plus descriptors that can be imported in operator’s network (SI) signalling.

The CI Plus Specification v1.4.x provides the description of a CI Plus LLP implementation based on the TS 103 205, Bluebook A173-2 and CI Plus 1.3 specification, pulling together those specifications and specifying what parts need to be implemented in order to realise a device compliant with CI Plus LLP. This specification is intended to be used in combination with the appropriate certification process, and subject to conformance by the manufacturers to the CI Plus Compliance and Robustness Rules. The CI Plus Specification v1.4.3 updates CI Plus Specification v1.4.2, introducing the CI Plus 2nd Root of Trust based on the SHA-256 Hash algorithm.

This specification provides the description of a CI Plus LLP implementation for a device supporting the USB form factor, profiles the TS 103 605 specification, and specifies the form factor(s) (PCMCIA or USB) that such a CI Plus LLP compliant device can support.

The ILA Addendum for ECP introduces enhanced security protection measures, designed to meet the security standards for content requiring Enhanced Content Protection (ECP). The CI Plus ECP Specification v1.1 specification builds upon the CI Plus 1.4 specification to define the requirements for a device suitable for receiving such content. This specification is intended to be used in combination with the appropriate certification process, and subject to conformance by the manufacturers to the ILA Addendum for ECP. DOWNLOAD

包括fastscan标准协议“M7 Fast Scanning Spec v7.1 Oct 17th 2017”和简单的业务说明。 5.FastScan简单说明 FastScan搜索基于两张表，FST（FastScan Services Table）和FNT（FastScan Network Table）。 搜索流程如下： 1.锁定主频点 或者 次频点，从TS流中获取FST和FNT。 2. 从FNT表中获取Tp 列表和节目列表，从FST中获取每个节目的具体参数。

本实验采用查询方式，甲机和乙机都工作在方式1下。甲机每当查询到中断信号有效时，便可从键盘读一个字符，乙机每当查询到中断信号有效时，便可以从a口读出数据并显示到屏幕。当甲机按下符号‘#’时，甲机发送完这个字符后就退出，乙机接送到字符‘#’时，不将它显示到屏幕，而是直接退出。由于双方都是计算机，工作速度非常快，只要有数据传到乙机就会被取走，因此对于甲机来说就可以看成，甲机时刻处于等待输入字符的状态。以下为甲机和乙机的源程序和流程图：

微机设计8255A主要对ADC0809进行控制和状态查询，ADC0809的主要功能完全靠其硬件连线来实现。当从键盘读一个esc键时程序结束，模拟量转换成的数字量以十六进制数表示。以下为源程序和流程图：
