DIGITAL BROADCASTING DEMODULATION APPARATUS WITH A DIRECTION ADJUSTMENT INDICATOR FOR THE RECEIVING ANTENNA

摘要

A signal of a desired channel is selected by a tuner (2) from digital broadcasting which is received by an antenna (1). The condition of the radio wave received by the antenna (1), which is judged from an AGC signal of the signal of the channel selected by the tuner, a Sync signal detected by a synchronization establishment unit (8) and the number of errors which have not been corrected by a forward error corrector (10) is displayed on an indicator (17). In this digital broadcasting demodulation apparatus, the receiving direction or position of the antenna can be easily decided on the basis of the condition of the received radio wave of the antenna (1), which is displayed on the indicator (17), so that received video has a C/N within thresholds.
