Embodiment Construction

[0051] Other objects, features, and advantages of the present invention can be clearly understood through the illustrations of the accompanying drawings.

[0052] Below with reference to accompanying drawing, the embodiment structure of the present invention and its effect are described; There are diagrams and the structure and effect of this invention illustrated by illustrations, at least one example will be used to illustrate; The composition and function of the core are not limited in any way.

[0053] The characteristic of the invention is that the intelligent antenna and the antenna control system are applied to the digital TV receiver. If the above-mentioned smart antenna and antenna control system are applied to a digital TV receiver, the receiving performance of the receiver in harsh and varied terrestrial wave channels can be improved. That is, the antenna system is always optimized and thus the reliability of the receiver can be improved. In addition, the present ...

Abstract

A control system of intelligent antenna for digital TV set applies catching and locking course so locking course can be omitted selectively. It is features as detecting maximum signal power direction quickly in catching course because AGC is fixed on specific value and obtaining the best antenna receiving result in locking course because multiple channel information is selectively integrated on antenna controller. The present invention can be applied on both simple and complicated intelligent antenna.

Description

technical field [0001] This is an invention about a smart antenna control system for digital TV reception applicable to vestigial sideband modulation (VSB) receivers. Background technique [0002] The research on the standard VSB (Vestigial Side Band) receiver antenna as a digital TV terrestrial channel transmission method is still in its infancy, but recently related concepts and ideas have been frequently announced to the world. In addition, as far as we know, ATSC (Advanced Television Systems Committee) has also completed the standardization (CEA / EIA909) work. [0003] Moreover, ATI (Next Wave) has passed the digital TV application experiment and is now conducting field tests. That is to say, the digital TV market itself is still in its infancy, so the technology related to digital TV receiving antennas is also in its infancy. [0004] Existing technologies are mainly antenna technologies suitable for wireless communication systems (such as portable terminals, military ...
