The Traveller Information Services Association (TISA) has recently released two new TPEG specifications.

The standards enable the digital transmission of Traffic and Traveller Information (TTI) via various types of delivery channel, e.g. Digital Radio (DAB), Internet, Digital TV (DVB), GPRS and Wi-Fi etc. TPEG, which stands for Transport Protocol Experts Group (similar to JPEG and MPEG), is defined in two series of standards that were both published in 2006:

• ISO/TS 18234:2006, Parts 1 to 6 – Binary Coding
• ISO/TS 24530:2006, Parts 1 to 4 – Extensible Markup Language (XML)

Both of the series of published standards contain sub-parts, which consider the use of TPEG for various applications. Other sub-parts are also under development for additional applications

The two new TISA specifications are:

• "TPEG Service Framework" Specification - describes the basic capabilities of the TPEG Generation 2 (TPEG2) series of new TISA Specifications for providing a multiplex of TPEG services and applications
• "TPEG Adaptation Layer Profiles, Part 1: Transmission via Digital Audio Broadcast - Packet Mode with Data Groups" Specification - provides a set of requirements to transmit TPEG Transport frames by Digital Audio Broadcast (DAB)

One key feature of TPEG technology is the concept of being "agnostic to bearers" and thus TPEG based services may operate via almost any simple digital data channel. These two specifications can be seen as contributing to this overall aim.

The TPEG Applications Work Group have reached the end of the review cycle, within the TISA community, and are thus close to final submission for standardisation.

HA recommended to review the specifications

ITS Radar International will continue to monitor developments in TPEG
