8、J series - Supplement 5 (09/1999) 1 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 permanent organ of the ITU. The ITU-T is responsible for studying tech

9、nical, 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 study by the ITU-T Study Groups whic

10、h, 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 necessary standards are prepared on a c

11、ollaborative basis with IS0 and IEC.

The technical topics that this Supplement covers a

32、re the ones listed below. Additional sections of the Supplement, covering additional topics, are in preparation. Section 1 - Point-to-point transmission of digital television for contribution and primary distribution. Section 2 - Secondary distribution of digital television by cable television syste

42、 Recommendation J.80 provides the specifications for a bit-rate-reduction codec. This codec is intended for use in the transmission of digital video signals for 625-line systems coded in components, according to Recommendation ITU-R BT.601. Recommendation J.80 applies to a transmission data rate clo

43、se to 140 Mbis, a data rate that is normally only used for contribution purposes. J series - Supplement 5 (09/1999) 1 1.2 Recommendation J.81 - Transmission of component-coded digital television signals for contribution-quality applications at the third hierarchical level of ITU-T Recommendation G.7

44、02 Recommendation J.81 provides the specifications for a bit-rate reduction codec. This codec is intended for use in the transmission of digital television signals at bit rates of about 34 or 45 Mbit/s, coded in components according to Recommendation ITU-R BT.601. Recommendation J.81 encompasses the

45、 coding algorithms needed for digital picture coding, and the interfaces with the transmission network. It applies to a transmission data rate of about 34 or 45 Mbit/s. These data rates are generally used for contribution and for primary distribution purposes. The video coding algorithms are based o

46、n a hybrid predictive transform scheme incorporating arrangements for variable word-length coding, synchronization and video framing. Provision is made for the transmission of audio and of teletext services to accompany the video information, and for the application of scrambling for conditional acc

47、ess. Network adaptation is specified to both plesiochronous and synchronous digital hierarchies. Recommendation J.81 should be studied in conjunction with its Amendments 1 and 2 and its Corrigendum 1. Amendment 1 provides guidelines for the implementation of the complete codec; Amendment 2 describes

48、 the results of interworking tests performed on practical codecs; Corrigendum 1 rectifies a number of small errors that appeared in the original text of Recommendation J.8 1. 1.3 Recommendation 5.82 - Transport of MPEG-2 constant bit rate television signals in B-ISDN Recommendation 5.82 covers the p

49、acketized transport of digital television signals in the broadband-ISDN. In the context of this Recommendation, television signals are digitally encoded and transmitted in compliance with WEG-2 systems specified in ITU-T Rec. H.222.0 I ISO/IEC 13818-1, at a constant bit rate in the Asynchronous Transfer Mode (ATM), which is the mode used by the B-ISDN. Other ITU-T Recommendations that apply in this area are those
