ConclusionsConclusions
Results of the TPEG-Project are a solid base BMT offers TPEG transmission infrastructureTPEG evaluation site shortly available at www.digitaltraffic.deFurther interface specifications/guidelines could ensure compatibility of TPEG-products
need for independent TPEG-test and evaluation suite to ensure „TPEG-quality“
BMT will continue TPEG-work in the TPEG-Forum Implementation Task Force (ITF)
