Measurement of digital video broadcasting-terestrial (DVB-T) signal in Malaysia / Tarmimi Sahad

DVB-T (Digital Video Broadcasting-Terestrial) is one of technical standard to deliver DTV (Digital Television), developed by the DVB Project. This standard is the most widely DTT (Digital Terrestrial Television) system used around the world since it was introduced in March 1997. One of the DVB-T main advantages is its flexibility, where the network can be designed to deliver various services such as multichannel SDTV (Standard Definition Television), HDTV (High Definition Television), fixed, portable, mobile and handheld reception. The quality of the DVB-T signal reception (Signal Coverage) is determined by Field Strength, MER (Modulation Error Ratio), BERbV (Bit Error Rate before Viterbi) and BERaV (Bit Error Rate after Viterbi). This research was conducted in order to investigate the coverage of DVB-T signal transmitted from a 5 kW transmitter at Menara Kuala Lumpur by measuring and analyzing the DVB-T parameters. In this research, a measuring vehicle equipped with measuring equipment and a receiving directional antenna. This receiving antenna is placed on a pole at a height of 10m above ground. Parameters quality of DVB-T which are field strength, MER, BERbV and BERaV for 100 test points in the coverage are measured, investigated and analyzed. The result shows 99% of the test point received a good DVB-T signal quality (reception possible).
