<hr><a name="_details"></a><h2>Detailed Description</h2>
General purpose link description for ATVEF (ITV, WebTV in the United States) and EACEM (SuperTeletext et al in Europe) triggers, Teletext TOP and FLOF navigation, and for links "guessed" by libzvbi from the text (e. g. page numbers and URLs). Usually not all fields will be used.

Teletext page links (no Closed Caption counterpart) can can actually reach across networks. That happens for example when <a class="el" href="group__Event.html#a12">vbi_resolve_link()</a> picked up a link on a page after we switch away from that channel, or with EACEM triggers deliberately pointing to a page on another network (sic!). So the network id (if known, otherwise 0) is part of the page number. See vbi_nuid. </td>

Trigger priority. 0 = emergency, should never be blocked. 1 or 2 = "high", 3 ... 5 = "medium", 6 ... 9 = "low". The default is 9. Apart of filtering triggers, this is also used to determine at which priority multiple links should be presented to the user. This field applies only to EACEM triggers, is otherwise 9. </td>
