Describes how the trigger messages defined in IEC 62297-1 are transmitted. A trigger is defined as information sent from a service provider as part of a data broadcasting transmission that initiates an application in a receiver.

IEC 62297-2:2005 specifies how trigger messages are broadcast using teletext technology. Both Page Format-Clear and Independent Data Line methods are defined, using protocols defined in ETSI EN 300 708. This bilingual version (2013-07) corresponds to the monolingual English version, published in 2005-05.
