TVCrossover Trigger

[This is preliminary documentation and subject to change.]

TVCrossover triggers contain URL information. They are formatted as shown following.

"5 <URL>[[attr1:val1][attr2:val2] ... [attrN:valN]]"

where

URL

Specifies a Uniform Resource Locator.

attrN

Specifies the name of the Nth attribute. A TVCrossover trigger can contain zero or more attribute:value pairs.

This parameter is optional. The default value is "type".

valN

Specifies the value of the Nth attribute.

Remarks

When the broadcast client receives a TVCrossover trigger, it fires a TVCrossover event, which can then be handled by scripts embedded in the enhancement page.
