ITU-T Recommendations

Web-based terminal middleware (WBTM) defines the functional interfaces for high-level resource management over an IPTV terminal device and describes the structure of a web-based presentation engine, which basically supports IPTV multimedia application frameworks in the ITU-T H.76x series of Recommendations. Web-based IPTV terminal middleware is based on ITU-T IPTV functional architecture and ITU-T terminal devices in the H.72x series of 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 any additional functionality for basic and advanced IPTV services. Annex A summarizes the general requirements.
