The system is an Interactive television technology platform comprising a microbrowser, a markup language, and a significant collection of associated software tools and services.
•
The WTVML microbrowser is currently available only as an OpenTV application, although an MHP version of the Waptv browser has been built for demonstration and proof of concept.

TV Sites for the OpenTV based Microbrowser are therefore web sites with a WTVML skin, and are often given a "wtv." sub-domain rather than a "www." sub-domain.
