13、038 ii FOREWORD The Alliance for Telecommunication Industry Solutions (ATIS) serves the public through improved understanding between carriers, customers, and manufacturers. The IPTV Interoperability Forum (IIF) develops requirements, standards, and specifications that will determine the industrys e
14、nd-to-end solution for Internet Protocol Television (IPTV). The mandatory requirements are designated by the word shall and recommendations by the word should. Where both a mandatory requirement and a recommendation are specified for the same criterion, the recommendation represents a goal currently
15、 identifiable as having distinct compatibility or performance advantages. The word may denotes a optional capability that could augment the standard. The standard is fully functional without the incorporation of this optional capability. Suggestions for improvement of this document are welcome. They
