本文件为DVB服务的使用和实施提供了实施指南 DVB数字电视环境中的信息（SI）编码，包括卫星、有线和地面网络。本指南旨在成为强烈推荐的DVB SI语法使用规则，如 EN 300 468[i.1]。因此，它们有助于高效、可靠地实现计算机中的基本用户交互功能 集成接收机解码器（IRD）。这些规则适用于广播公司、网络运营商以及制造商。这些规则以DVB SI流的约束形式或IRD的预期解释形式指定。这些功能的规范绝不禁止IRD制造商包括附加功能，以及 不应被解释为对履行规定了任何形式的上限。 该指南不包括与用户界面细节或高级电子节目指南（EPG）相关的功能。 这些问题留给市场来解决。注:强烈建议IRD的设计应考虑到未来的兼容扩展 DVB SI语法。所有字段“保留”（适用于ISO）、“保留的未来使用”（适用于ETSI）和“用户” EN 300 468[i.1]中定义的“应被设计为不使用它们的IRD忽略。” “保留”和“保留未来使用”字段可由各自机构在未来指定， 然而，“用户定义”字段将不会标准化。本文件使用EN 300 468[i.1]中定义的术语，应与该EN一起阅读。预计本文件将成为一份技术规范（TS），因此全文将使用 本文件是TS的文件。

The present document provides implementation guidelines for the use and implementation of the DVB Service Information (SI) coding in a DVB digital TV environment including satellite - cable - and terrestrial networks.The guidelines are intended to be highly recommended rules for the usage of the DVB SI syntax specified in EN 300 468 [i.1]. As such, they facilitate the efficient and reliable implementation of basic user-interaction functions in Integrated Receiver-Decoders (IRD).The rules apply to broadcasters, network operators as well as manufacturers.The rules are specified in the form of constraints on the DVB SI streams or in terms of intended interpretation by IRDs.The specification of these functions in no way prohibits IRD manufacturers from including additional features, and should not be interpreted as stipulating any form of upper limit to the performance.The guidelines do not cover features related to user-interface details or advanced Electronic Program Guides (EPG). Such issues are left to the marketplace.NOTE: It is highly recommended that the IRD should be designed to allow for future compatible extensions to the DVB SI syntax. All the fields "reserved" (for ISO), "reserved_future_use" (for ETSI), and "user defined" in the EN 300 468 [i.1] should be ignored by IRDs designed not to make use of them. The "reserved" and "reserved_future_use" fields may be specified in the future by the respective bodies, whereas the "user defined" fields will not be standardized.The present document uses the terminology defined in EN 300 468 [i.1] and should be read in conjunction with that EN.It is envisaged that the present document become a Technical Specification (TS), and therefore the text used throughout the present document is that of a TS.
