Analysis Performance of QoS and QoE Digital Television in Urban Area

Abstract

Indonesia is currently starting to implement a digital TV broadcasting system where digital TV provides benefits in the form of cleaner, clearer, and more stable images and sound. Despite using a more sophisticated system, it is hoped that the use of existing devices can still be used to receive digital TV broadcasts so that users do not need to upgrade their devices. With a dense and diverse population of utilities, the implementation of broadcasting in urban areas often experiences problems on the user side. Objects such as trees, houses, or high-rise buildings, cause the signal from the transmitter undergoes multipath fading to be received by the user which cause the quality of service and quality of experience is not as expected. Measurements were made for two TV stations that have broadcast digitally in Surabaya, namely channels 27 UHF and 41 UHF. Both of these transmitters are located in Sambikerep sub-district. Field measurement were taken in 10 locations in Surabaya for fixed condition. The measurement results using the Yagi Uda antenna show that this antenna can still be used for digital TV reception in urban area. While digital TV broadcasts are acceptable, some locations show poor quality results due to multipath fading. From the measurement results in 10 locations in Surabaya, for QoS measurement, 80% have a good classification, 15% have a fair classification, and 5% have a poor classification. For QoE measurement, 15% have good classification and 85% have fair classification.
