18、munications Standards Institute (ETSI). NOTE: The EBU/ETSI JTC was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is
19、 responsible for the standardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active mem
20、bers in about 60 countries in the European broadcasting area; its headquarters is in Geneva. t European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 Dlgltal Video Broadcasting (DVB) Project Founded in September 1993, the DVB Project is a
21、market-led consortium of public and private sector organizations in the television industry. Its aim is to establish the framework for the introduction of MPEGP based digital television services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters market-l
22、ed systems, which meet the real needs, and economic circumstances, of the consumer electronics and the broadcast industry.

24、 MPEG-2 Transport Streams (TS) between two DVB interfaces as defined in EN 50083-9 a within Plesiochronous Digital Hierarchy (PDH) networks working at the ITU-T Recommendation G.702 8 hierarchical bit-rates of 1 544 kbit/s, 2 048 kbit/s, 6 312 kbit/s, 8 448 kbit/s, 34 368 kbit/s, 44 736 kbit/s and 1
25、39 264 kbit/s. The use of any of these bit rates is optional, if however one or more rates are selected the complete specification applies. The definition of the network aspects of the transmission of MPEG-2-TSs is based to the maximum extent on existing international and European standards. The equ
26、ipment considered in this ETS is the Network Adapter performing the adaptation between MPEG-2-TSs and the interfaces of PDH networks. 2 Normat ive references This ETS incorporates by dated and undated reference, provisions from other publications.

RS coded MPEG-2 Transport Stream (TS) packet: A data packet possessing a length of 204 bytes. Bytes 1 to 188 contain an MPEG-2-TS packet
40、. Bytes 189 to 204 contain the parity-check bytes for the error correction of the preceding bytes of this packet. These paritycheck bytes are generated using a shortened Reed-Solomon code RS(204,188). 3.2 Abbrevlatlons For the purposes of this ETS, the following abbreviations apply: AAL AS1 ATM BER

44、irtual Path VP Entity VP Multiplexing Entity 4 Baseline specification The Network Adapter is an equipment which performs the adaptation of data structured as an MPEG-2-TS to the characteristics of a PDH link (see ITU-T Recommendation H.222.0 19). The solution selected for the transmission of MPEGP-T
45、S packets, respectively RS coded MPEG-2-TS packets, over PDH links is based on the use of ATM cells. Therefore, the adaptation of the transport of an MPEGQ-TS basically consists in: - - adaptation of MPEG-2-TS packets or RS coded MPEG-2-TS packets to ATM cells; adaptation of ATM cells to PDH framing
46、. The normative references applicable to the adaptation unless specifically mentioned are given here below: - the adaptation of MPEGQ-TS packets into ATM cells using an AAL type 1 shall be performed as described in ITU-T Recommendation J.82 24. AAL type 1 is specified in ITU-T Recommendation 1.363.1
47、 21, the ATM layer is specified in ITU-T Recommendation 1.361 20; the adaptation of ATM cells into PDH framing shall be performed as described in ITU-T Recommendation G.804 14. - There is no normative reference for the adaptation of RS coded MPEG-2-TS packets to ATM cells. This adaptation shall be p
48、erformed as described in ITU-T Recommendation J.82 24 for MPEG-2-TS packets, with the only exception that the RS coded MPEG-2-TS packets are not aligned with the structure of the AAL1 interleaving matrix. The Network Adapter is described as a group of functional blocks. The partitioning into functio
49、nal blocks is based on existing recommendations on Synchronous Digital Hierarchy (SDH) equipment (ITU-T Recommendation G.783 13) and ATM equipment (ITU-T Recommendation 1.732 23). The equipment consists of the following blocks (see also figure 1): - MPEG Physical Interface; - MPEG/ATM Adaptation; - ATMNP Termination; - VP Multiplexing Entity; STD.ETS1 ETS 300 B23-ENGL 1777 3400855 024b523 455 Page 10 ETS 300 81 3: December 1997 MPEG2 System layer (Transport Stream) RS coded MPEG2-TS ATM Adaptation Layer type 1 ATM layer Transmission Converg
