6、er to ITU-T List of Recommendations. ITU-T RECOMMENDATION J.117 HOME DIGITAL NETWORK INTERFACE SPECIFICATION Summary The need to support cable services for High Definition TV (HDTV) sets, which are starting to emerge in the retail market, is converging with a general movement to interconnect multipl
7、e audio/visual (AN) devices on a common bus or network. The IEEE 1394 interface has emerged as the preferred tool to accomplish this goal. Although the applications and their standards are still emerging, this Recommendation defines requirements and options for a 1394 digital interface between a Hom
8、e Digital Network Device (“D), which is a type of Set-Top Box (STB), and a Digital Tele- vision (DTV) receiver, with the Recommendation later extended to include a full set of networked devices in the home. Clause 5 covers the interface from the HDND point of view. Clause 6 covers the interface from
9、 the DTV point of view. In the event of apparent conflict, the requirements in Clause 5 take precedence over Clause 6. I l Source ITU-T Recommendation J.117 was prepared by ITU-T Study Group 9 (1997-2000) and was approved under the WTSC ResolutionNo. 1 procedure on 16 September 1999. Recommendation
10、J.117 (09199) i STD-ITU-T RECMN J.117-ENGL L999 D 48b2591 Ob74413 b95 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommuni- cations. The ITU Telecommunication Standardization Sector (ITU-T) is a pemnent organ of the ITU. The ITU-T
11、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 Conference (WTSC), which meets every four years, establishes the topics for stud
12、y by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessa
13、ry standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the
14、 possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outsid
15、e of the Recommendation development process. As of the date of approval of this Recommendation, the ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the late
16、st information and are therefore strongly urged to consult the TSB patent database. O ITU 2000 All rights reserved.

32、TD*ITU-T RECMN J-LL7-ENGL Il999 Introduction This Recommendation describes a Home Digital Network Interface (HDNI) specification using the IEEE 1394 High Performance Serial Bus for networking between a Home Digital Network Device (HDND) such as a set-top box, and a Digital Television (DTV) receiver.
33、 Protection of program content is also provided against unauthorized copying during transmission across this interface. The IEEE 1394 High Performance Serial Bus offers bi-directional communication capability with a high data rate in excess of 200 Mbit/s on an interactive network of devices connecte
34、d within the home. One of the key advantages of the HDNI architecture is that all of the cable-specific protocols and interfaces are in the HDND. This permits the cable operator to support currently implemented systems, as well as promote special cable- based applications without changes to the cons
35、umers basic AN equipment. In particular, the conditional access, network management, cable channel lineups, transport modulation, Internet transport technology, and other cable- specific technology are transparent to the delivery of the cable services using the set-top HDND connected to a DTV receiv
36、er via this interface. vi Recommendation J.117 (09/99) STDnITU-T RECMN J.LL?-ENGL 1999 m 48b2591 Ob34418 177 m Recommendation 5.117 HOME DIGITAL NETWORK INTERFACE SPECIFICATION (Geneva, 1999) 1 Scope The need to support cable services for High Definition TV (HDTV) sets is converging with a general m
37、ovement to interconnect multiple audio/visual (AN) devices on a common bus or network. The IEEE 1394 interface has emerged as the preferred tool to accomplish this goal. This Recommendation defines requirements and options for a serial baseband Home Digital Network Interface (HDNI). This interface c
38、an connect a Home Digital Network Device (HDND), which is a type of Set-Top Box (STB), with a Digital Television (DTV), that can decode and display an HDTV program. Protection of program content against unauthorized copying at this interface is addressed separately in Recommen- dation J.95. This Rec
39、ommendation will later be extended to include a full set of networked devices in the home. With this in mind, a set of profiles will be defined to extend the functionality of the On-Screen Display (OSD) incrementally for the Electronic Program Guide (EPG) and other application software running in th
40、e HDND. This version of the Recommendation will focus on Profile O for a directly connected DTV. I It is expected that one of the key advantages of an HDNI architecture is that all of the cable-specific protocols and interfaces are in the HDND. This permits the cable operator to support proprietary
41、legacy systems, as well as promote special cable-based applications without changes to the consumers basic AN equipment. In particular, the conditional access, network management, cable channel lineups, transport modulation, Internet transport technology, and other cable-specific technology are tran
42、sparent to the delivery of the cable services using the HDNI. The cable operators electronic program guide as an integrated and up-to-date navigational environment presents the customers package of services. This functional partitioning moves much of the processing currently done in the set-top box
43、into the consumers device. For example, a DTV system can decode the compressed video and overlay the HDND graphical user interface onto the TV display, where both compressed video and graphics are received from the HDND over the connecting serial bus. 2 References The following ITU-T Recommendations
