This study presents the evaluation of digital video broadcasting-terrestrial second generation (DVB-T2) Television signal quality in Jos using Integrated Television Services Limited signal. The delivery of quality Television signal remains problematic in Nigeria due to signal attenuation and degradation between the transmitter and receiver station. This is primarily due to environmental and atmospheric perturbations prevalent along the signal paths. This research aim is to determine the signal quality of DVB-T2 Television system in Jos, Plateau State. The simple field measurement methodology was adopted in measuring field strength and channel power parameters. These measurement parameters were used to calculate for carrier-to-noise ratio (CNR) and signal-to-noise ratio (SNR) through empirical method. Finally, CNR and SNR were used to determine the signal quality of DVB-T2 signal in Jos. The result of the research shows that DVB-T2 signal in the primary service areas has good and reliable signal apart from the rocky environments.

The nature of the man/machine interface in the color television system as used for home entertainment is explored and described. The problem of predicting picture quality is examined from the point of view of the receiver designer/manufacturer. The relevance of existing performance data, perference data, and physical measurements of image characteristics to the picture quality question is examined. Existing models and part-models are described, and the characteristics of a more complete, but hypothetical model are outlined. Fundamental limitations in the predictability of picture quality are described. These limitations arise in large part from the fact that many important factors in picture quality, such as quality of the broadcast signal, viewing conditions, and personal preferences are not controllable by the receiver manufacturer.
