Abstract

The invention provides a high-practicability DVB-T2TVDongle digital television receiver. The high-practicability DVB-T2TVDongle digital television receiver comprises a control circuit board and an HDMI plug connector and a micro USB plug connector separately arranged at both end portions of the control circuit board; the HDMI plug connector and the micro USB plug connector are electrically fixed to the control circuit board by soldering; and the control circuit board is provided with a MSA7TXX series DVB-T2 low power consumption digital set-top box decoding chip. The high-practicability DVB-T2TVDongle digital television receiver also comprises a three-in-one signal line assembly used for connecting to the micro USB plug connector and performing data signal transmission; and the three-in-one signal line assembly includes a USB power supply line, an infrared receiving line and an RF antenna. In an actual application process, since the USB power supply line 131, the infrared receiving line 132, and the RF antenna 133 are combined in three lines, and one line realizes all functions, which brings great convenience to the user; therefore, the structure is simple and convenient, and doesnot occupy space; the cost is greatly reduced; and the packaging is simple.

Description

[technical field] [0001] The invention relates to the technical field of TV signal connecting wires, in particular to a highly practical DVB-T2 TV Dongle digital TV receiver capable of effectively reducing costs. [Background technique] [0002] At present, the set-top box with DVB-T2 digital TV function on the market must be powered separately, and the external accessories are many and costly, and the production process is complicated, occupying space, which is not conducive to actual use, especially when the equipment is abnormal, it is not convenient for follow-up maintenance. [0003] How to better reduce the cost (without power board or adapter), make the installation simple and convenient, and not take up space, is a problem often considered by those skilled in the art. A lot of research and development and experiments have also been carried out, and better score. [Content of the invention] [0004] In order to overcome the problems in the prior art, the invention pr...
