Optimal Regional Discrimination Method of Regional Sensing Tuning System

摘要

According to the present invention, in performing automatic tuning in an arbitrary area by using preset data for each region, an area detection is performed so that a preset operation can be performed in an area having more broadcasting frequencies by using the accumulation frequency of frequency data from which noise components are removed. The tuning system is intended to provide a method for determining the optimal area.;To this end, the present invention comprises the first step of performing all broadcast frequency search operations for all frequency bands that can be received and detecting only a reception frequency that does not include a noise component among tuned reception frequencies; By comparing and comparing the detected reception frequency with the stored broadcasting frequency data for each region, detecting and accumulating the number of indexes of region discrimination of the matched broadcasting frequency, and selecting the region with the highest accumulation number as the optimal broadcasting receiving region. Comprising a second process, wherein the first process is a first step of detecting the same frequency by comparing the electric field sensitivity of any frequency currently received with the electric field sensitivity of each preset broadcast frequency, and the detected reception frequency If the signal level is constant, it is judged as a reception frequency containing noise component and canceled. If the signal level is not constant, it is judged as a reception frequency without noise component. The second step is to temporarily store.
