National Grid Wireless, one of the UK’s leading providers of broadcast infrastructure, has begun technical trials of DAB-IP and T-DMB, two of the bearer technologies, which could be adopted for the provision of mobile media services in the UK. The services are being transmitted on the Stoke-on-Trent DAB multiplex and carry video and audio content supplied by the operators of the multiplex, UTV-Emap Digital. The technical trial is monitoring the relative performance of both technologies in rural and urban areas, including within buildings. The trial will enable the company to determine the full requirements for the introduction of enhanced data services onto conventional T-DAB platforms. The multiplex system has been provided by RadioScape and is currently the only system operating that supports both T-DMB and DAB-IP. The video encoding system has been provided by Pixtree. National Grid Wireless will release the results of the trial in late 2006.
