Vornorm CEN ISO/TS 24530-3:2006 (E) 4 Introduction TPEG in XML (tpegML) provides the solution to diverse requirements for the ultimate delivery of TPEG applications (potentially simultaneously) via for example ARIB, ATSC, DAB, DVB and the In

25、ternet. This will solve the minimal adaptation layers requirement and without doubling up on message carousels, which are handled at different layers of the protocol stacks. The original TPEG technology uses a byte-oriented stream format, which may be carried on almost any digital bearer with an app

26、ropriate adaptation layer. TPEG messages are delivered from service providers to end-users, and are used to transfer application data from the database of a service provider to an end-users equipment. TPEG binary was initially designed to meet a particular brief, from the EBUs Broadcast Management C

27、ommittee; to develop a new protocol for Traffic and Travel Information, for use in the multimedia broadcasting environment. TPEG applications were developed with service and transport features, which enable travel-related messages to be coded, decoded, filtered and understood both by humans (visuall

28、y and/or audibly) and by agent systems. This brief was also endorsed by the EBU TTI Broadcast Strategy Team, who recognized the vital importance of a bearer independent TTI protocol. The development of TPEG binary technology is excellently matched both technically and economically to DAB and possibl

29、y to internet bearers, where of the order of up to 10 kbits/s is considered acceptable. However other bearers such as ARIB, ATSC and DVB may be able to offer much higher data rates with economic and technical utility. Nevertheless these bearers are highly structured (layered) in their ability to han

30、dle transparent data services and they include mechanisms suitable for carousel delivery, which would require a considerably different TPEG data structure before real transparency could be achieved. Another potential use of tpegML is provided to Service Providers who would have a standardised messag

31、e generation interface, yet be able to develop systems suited to their own requirements. This will enable Service Providers to exchange pre-edited information regardless of their message generation systems and be substantially language independent. tpegML has been developed using the DTD approach, w

32、hich allows the use of different language entity files to easily provide a truly language independent service. This approach has the advantage that tpegML files can be rendered in any language, provided the language entity file is available to the internet browser. This document provides English lan

33、guage entity files only. For other languages the entity files in this document only require direct translation. The development of this ISO/TS 24530 series was undertaken jointly with European Broadcasting Union B/TPEG Group, which has evolved into the TPEG Forum Standards Task Force. Attention is d

34、rawn to the EBU sponsored TPEG Forum development principles, which require all inputs containing IPR to be declared during drafting work. No such declarations have been made. Vornorm CEN ISO/TS 24530-3:2006 (E) 5 1 Scope This document establishes the XML encoding of the method of the Road Traffic Me

35、ssage application. The TPEG-RTM Application is intended to convey information to road users. The information provided relates to event and some status information on the road network and on associated infrastructure affecting a road journey. For example, limited information about abnormal operation

36、of links in the network may be included, such as ferries, lifting-bridges, etc. The TPEG-RTM Application has the broad objective to allow the generation of Traffic and Travel Information (TTI) messages, for delivery to the end-user by one or more bearers. A hierarchical methodology has been develope

37、d to allow the creation of messages from a set of TPEG-RTM tables, which are essentially word-oriented and cover most needs. These TPEG-RTM tables (essentially word-oriented data object dictionaries) comprise a wide ranging ability to describe a TTI event and some status information, introducing new

38、 precision in a number of areas such as “Vehicle types”, “Positional information on the carriageway” and “Diversion routing advice”. It is vital, for further understanding of this document, to have more than a passing understanding of the TPEG-RTM binary specification which describes, among other th

39、ings, in a step-by step approach: Message Management, Level One Classes and how they are structured, hierarchically to provide a full Road Traffic Message together with the TPEG Location Referencing system. 2 Normative references The following referenced documents are indispensable for the applicati

47、is document This document is divided into Sections, each describes an XML element used in tpegML. Each element has an introduction explaining what it is for, the DTD definition relevant to it, guidelines “extending” the DTD and an example. The complete .dtd and .ent files are contained in Annexes A

48、and B. 4.1 Tables A large number of attributes used in elements in tpegML are based on tables in the TPEG specifications. To encode this in XML there are defined general entity references for all the table entries. In this Technical Specification series these entities are taken from the TPEG tables

49、defined in the equivalent part of ISO/TS 18234. For display in other languages these entity files only need to be replaced by directly translated equivalents. These are named, for example rtmX_Y, where X is the table number and Y is the row number (e.g. “rtm01_01” is the entry in the RTM vehicle_type table for car). The DTD does not restrict the entity references that can be used in an attribute so the guidelines sections indicate which entities/ta
