International Telecommunication Union ITU-T Technical Report (12/2013) TELECOMMUNICATION STANDARDIZATION SECTOR OF ITU JSTR-SCTV-01 Technical Report on Smart Cable Television Technical Report on Smart Cable Television Acknowledgements This FG Technical Report was prepared under the leadership of Mr Thomas Russell, Chairman of ITU-T Focus Group on Smart Cable Television. It is based on the contribution of numerous authors who either contributed to the generation of the relevant ITU-T Recommendations or participated in the focus group activities. In particular, credit should be given to the Focus Group participants representing the following organizations: Academy of Broadcasting Science, China; Cambridge University, UK; Cisco Systems, USA; ETRI, Korea (Rep. of); ITU-T FG AVA; Japan Cable Laboratories, Japan; KDDI, Japan; Oriental Cable Network, China; SCTE, USA; and the ITU-TSB staff who have contributed to finalize the text. Study Group 9 approved this document as a study group Technical Report at its Geneva, 3 - 11 December 2013 meeting. JSTR-SCTV-01 (2013-12) i FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-T's purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE This is an informative ITU-T publication. Mandatory provisions, such as those found in ITU-T Recommendations, are outside the scope of this publication. This publication should only be referenced bibliographically in ITU-T Recommendations. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http://www.itu.int/ITU-T/ipr/.
