Broadcasting receiving apparatus with a geomagnetic sensor to control the directivity of the antenna |
| 摘要 |
<p>A terrestrial magnetism sensor generates bearing signal with respect to predetermined geometric direction of antenna. An antenna control signal generator generates antenna control signal based on the bearing signal, such that tuner is controlled to receive the EM wave.</p> |
