ISO TS 18234-2:2006建立了TPEG数据流中使用的参考方法，以允许服务提供商在另一个承载信道上发出相同服务可用性的信号，或从另一个服务发出类似服务数据的信号。TPEG是一种面向字节的流格式，几乎可以在任何具有适当适配层的数字载体上传输。TPEG消息从服务提供商传递给最终用户，用于将应用程序数据从服务提供商的数据库传输到用户的设备。该协议采用分层结构，并采用了通用的成帧系统，该系统具有适应性和可扩展性，可承载可变长度的帧。它的设计具有几乎所有级别的显式帧长识别能力，提供了更大的灵活性和完整性，并允许修改协议和添加新功能，而不会干扰早期客户机解码器模型的操作。

ISO TS 18234-2:2006 establishes the method of referencing used within a TPEG data stream to allow a service provider to signal availability of the same service on another bearer channel or similar service data from another service.TPEG is a byte-oriented stream format, which may be carried on almost any digital bearer with an appropriate adaptation layer. TPEG messages are delivered from service providers to end-users, and are used to transfer application data from the database of a service provider to a user's equipment.The protocol is structured in a layered manner and employs a general purpose framing system which is adaptable and extensible, and which carries frames of variable length. This has been designed with the capability of explicit frame length identification at nearly all levels, giving greater flexibility and integrity, and permitting the modification of the protocol and the addition of new features without disturbing the operation of earlier client decoder models.
