An inaccuracy antenna direction causes the channel searching on DVB-T2 STB to be difficult. Tracking antenna system with auto-tracking capability is the applicable technology which can facilitate the process of channel searching. In a real implementation, the tracking antenna systems need reference parameters which are easily obtained and easily processed on the processors with limited capabilities. The focus of this paper is how to obtain reliable input parameters for the tracking antenna system. Fuzzy Inference system is not used for tracking method but to improve input parameters processing. This paper proposes two possible parameters, among others are the signal indicator and CVBS luminance level. FIS (Fuzzy Inference System) is used as a real-time VQA (Video Quality Assessment) and makes both of parameters as FIS input. The test result shows that both parameters are very feasible to be used as input parameters for tracking antenna system. FIS simulation shows that this algorithm has good performance. This is shown by the simulation results that FIS can adjust the parameter characteristics.
