Abstract

The invention discloses a multi-antenna digital television box, comprising a plurality of receiving antennas, a comparator connected with the receiving antennas and a digital television chip, wherein each receiving antenna is provided with a receiving signal; the comparator is used to compare receiving signals, and select a stronger receiving signal from the receiving signals, and the stronger receiving signal can be input to the digital television chip and converted to a video signal to be outputted. The invention also discloses a receiving method for the multi-antenna digital television box.

Description

technical field [0001] The present invention relates to a digital TV box, and in particular to a digital TV box with multiple antennas and a receiving method thereof. Background technique [0002] Digital TV has become one of the hottest trends in the digital age because it can provide high picture quality, more capacity and interactive functions. At present, there are three main standards for the development of global digital TV related standards, namely DVB (Digital Video Broadcasting) formulated by the European Broadcasting Union, ATSC (Advanced Television Systems Committee) in the United States, and ISDB (Integrated Services Digital Broadcasting) in Japan. [0003] A digital TV box is mainly a device that converts an analog signal into a digital signal, and then further converts it into a display format. Or, with the popularization of digital TV, the digital TV box can also directly receive the digital TV signal and convert the digital signal into a display format. [...
