EBU © MMV 2 Summary TPEG started back in 1997 What is TPEG technology for? Content and Delivery segments TPEG technology is already standardised ! TPEG Open Standards TPEG technology – a universal solution The TPEG Forum, RTIG… and GST IP… TPEG-Loc - discussion and future

EBU © MMV 3 TPEG started way back in 1997 By autumn 1997 – some leading edge EBU Members realised that the Traffic and Travel Information (TTI) service-data technology known as RDS-TMC would not satisfy an increased demand for multi-modal travel information and it would not last for ever! RDS-TMC is a single delivery channel (FM Radio/RDS) constrained (and therefore compressed) data solution A replacement system must be much more future proof Nevertheless RDS-TMC services supporting vehicle based (on-board) Navi-systems are now expanding across Europe!

EBU © MMV 4 Basic Ideas of EBU for TPEG Adopt traffic information system to digital broadcasting Make use of advantageous features of RDS/TMC Take * standardized digital event codes * digital georeferenced location codes * add verbal announcements if wanted

EBU © MMV 6 What is TPEG technology for ? End-user focussed TTI services … Language-independent structured messages… Multimodal TTI - with various applications (RTM, PTI etc) A toolkit for other Application developers… (PKI, CTT, WEA) From the segments of the TTI domain, TPEG technology was originally focussed on the Delivery (Service Provision) segment But now we are beginning to see an important use for TPEG technology in the Content Collection segment

EBU © MMV 7 Classical Content and Delivery segments basically common to all RTTI-systems

EBU © MMV 8 TPEG technology allows delivery on different platforms Digital Radio (DAB), Internet, Digital TV (DVB) Applications originally developed for Digital Radio BINARY STANDARD (CEN/ISO TS Series) Adopted: Applications developed for Internet bearers & message generation using XML tpegML STANDARD (CEN/ISO TS Series) Adopted: TPEG technology - is already standardised !

EBU © MMV 10 Language independence Service provision for map-based and text-based systems Client filtering by location co-ordinates and by message content text Support for all transport networks (multi-modal and inter- modal) Extensible and expandable – “toolkit” support for new TPEG Applications … Agnostic about bearers Every location or area on earth covered with WGS 84 co-ords TPEG technology “toolkit” - offers a universal solution …

EBU © MMV 11 The TPEG Forum (1) The TPEG Forum has been established by the EBU with the following objectives: To encourage implementation of TPEG in services and products To facilitate exchange of information about practical implementation of TPEG To maintain the existing TPEG standards To develop new applications of TPEG and, where appropriate, to develop new specifications The TPEG Forum is building on the last 8 years of work on TPEG by the EBU B/TPEG group and 3 years of the TPEG Project activity The TPEG Forum is presently free to all - to join

EBU © MMV 12 The TPEG Forum (2) To meet the EBU and International Standards Organisations requirements the TPEG Forum has established: Standards Task Force (concurrently CEN TC 278 WG4.7 and ISO TC204 WG10.7) Implementation Task Force The TPEG Forum will establish: Marketing Task Force TPEG Forum membership is growing monthly: Especially from Asia-Pacific countries

EBU © MMV 13 RTIG = Road Traffic Information Group … The TPEG Forum – with EBU agreement and support – has been instrumental in establishing the Road Traffic Information Group – working with the TMC Forum A key topic to be solved is related to another Location Referencing method proposal: AGORA-C The TPEG Forum has offered a solution: signalling “Another Loc”…= Combination suitable for: AGORA-C, by keeping it separately specified RDS-TMC Location Codes, which many are requesting A unified solution (combining the best of all) would be ideal- the TPEG Forum has strongly proposed this next step… Agreement with the “AGORA community” is to be found… Advantage: Use of RDS/TMC + new data solution in parallel as long as reasonable

EBU © MMV 14 GST IP … The GST IP Safety Channel Sub Project – is considering adopting many aspects of the TPEG “toolkit”… Developing a definition for Safety Messages that can be applied throughout the value chain … using TPEG-RTM Determining an agreeable Location Referencing method … using TPEG-Loc
