Web-based terminal middleware (WBTM) defines high-level resource management functional interfaces over an IPTV terminal device and the structure of web-based presentation engine, which basically supports the IPTV multimedia application frameworks in the ITU-T H.760 sub-series of Recommendations. Web-based IPTV terminal middleware is based on the ITU-T IPTV functional architecture and the ITU-T terminal devices in the H.720 sub-series or Recommendations. ITU-T web-based IPTV terminal middleware is necessary to support basic and advanced interactive IPTV services for IPTV terminal devices.

This Recommendation also describes the general WBTM requirements for IPTV services and additional functionality for basic and advanced IPTV services. Annex A summarizes the general requirements.
