Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards Institute (ETSI). NOTE: The EBU/ET
12、SI JTC Broadcast was established in 1990 to Co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is responsible for the standardization
13、 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 members in about 60 countries in the Eu
14、ropean broadcasting area; its headquarters is in Geneva.

15、ion industry. Its aim is to establish the framework for the introduction of MPEG-2 based digital television services. Now comprising over 200 organizations from more than 25 countries around the world, DVB fosters market-led systems, which meet the real needs, and economic circumstances, of the cons

ETSI 5 ETSI TS 102 813 V1.l.l (2002-11) 1 Scope The present document covers a wired Home Network Segment based on IEEE 1394 technology, as described in the Architecture Framework document i. The present document concentrates on how IP traffic for DVB serv
17、ices will be carried over IEEE 1394 technology. This covers the encapsulation of IP packets in the IEEE 1394 Serial Bus packets. All the IP related functionality such as initial registration and configuration (including IP address assignment) are covered in other standards. In terms of the IPI Archi
18、tecture document, the present document pertains to the interfaces IPI- 1, IPI-2 and IPI-3. It is not the intention to come up with a completely new standard but to refer as far as possible to existing standards. The present document should meet the existing commercial requirements as defined in CM25
19、5rev4 (see Bibliography). 2 Re fe re nces The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication andor edition number or version number) or non-specific. For a
20、specific reference, subsequent revisions do not apply.

25、y) Video bearer (lower priority) Best effort data Voice and video signalling Based on the description of a Home Network Segment (HNS) in the architectural framework specification i, an IEEE 1394 - HNS consists of one IEEE 1394 bus. The physical topology of an IEEE 1394 bus is a tree structure. The d
26、escription of the Home Reference Model in the architectural framework specification i, furthermore introduces a so-called Home Network Connecting Device (HNCD). An HNCD can act as a bridge, router or gateway and connects HNSs with each other. Based on this, an HNCD connecting two IEEE 1394 buses wit
27、h each other will contain a bridge component based on the IEEE 1394 bus bridge specification 2. The general specification of the IEEE 1394 media and connectors, physical layer, and data link layer, can be found in clause 3.1 through 3.3 of the DVB-IHDN Home Local Network specification 3.

Therefore the interfaces IPI-1, IP
29、I-2, and IPI-3 on an IEEE1394 - HNS, shall comply to the IETF specification IPv4 over IEEE 1394 4. For the addressing of devices on an IEEE 1394 network, some fields of DHCP have to be filled in a specific way, due to the fact that IEEE 1394 uses a different link layer addressing method than convent
30、ional IEEE802/Ethernet. Therefore, all the IP-based traffic shall also comply to the IETF specification DHCP for IEEE 1394 5. This means that this IETF specification has to be supported on the interfaces IPI-1, IPI-2, and IPI-3 in case of an IEEE 1394 - HNS. All other IP-based functionality required
31、 to carry IP traffic over an IEEE 1394 - HNS and via an HNCD connecting two IEEE 1394 buses or an IEEE 1394 bus with another type of HNS can be found in the network provisioning and IP addressing specification Draft IPI200 1-071 (see Bibliography). 6 QoS Because it is expected that the IP traffic tr
32、ansported on a network will consist of types with varying importance, priority levels shall be given to the different traffic types. Therefore all traffic on the interfaces IPI-1, IPI-2, and IPI-3 has to be marked to ensure consistency. The marking shall be based on the DiffServ CodePoint (DSCP) mar
33、king method 6 as is shown in table 1. For a HNS based on IEEE 1394 these DSCP values are used to map a traffic type on the corresponding IEEE 1394 transaction code. The IEEE 1394 transaction codes are described in the IETF specification IPv4 over IEEE 1394 2 ETSI 7 ETSI TS 102 813 V1.l.l (2002-11) Annex A (informative): Bibliography CM255rev4 (03/200 1): “Commercial Requirements for Multimedia Services over Broadband IP in a DVB Context“ Draft IPI200 1-07 1 : “Network Provisioning and IP Addressing“.
