Problems solved by technology

However, due to the fast-moving and unfixed characteristics of mobile vehicles including taxis and buses, they may move to places far away from the transmission center. Due to the fading of the signal, the received signal will be very weak and the TV quality will be poor. Poor problem, which affects the normal playback of information

Abstract

The invention relates to a vehicle-mounted MIMO (multiple-input and multiple-output) type DVB-T (digital video broadcasting-terrestrial) receiver, which comprises two receiving antennas, a down-conversion processing module, a channel data decoding module, a demultiplexing module and a TS (transport stream) packet analyzing module, wherein the two receiving antennas, the down-conversion processing module, the channel data decoding module, the demultiplexing module and the TS packet analyzing module are sequentially connected to carry out radio frequency signal receiving, down-conversion processing, channel data decoding, demultiplexing and TS packet analyzing on a received MIMO type DVB-T signal which is transmitted in a DVB-T channel, so as to obtain audio compression and decoding data, video compression and decoding data and additional-data encoding data to broadcast audio and video contents. The receiver has the advantage that the signal receiving quality of the vehicle-mounted digital television signal is improved by the MIMO technique, so the technical problems of weak receiving signal and poor television quality caused by the vehicle-mounted mode are solved.

Description

technical field [0001] The invention relates to the field of vehicle-mounted television reception, in particular to a vehicle-mounted multiple-input multiple-output MIMO type digital television terrestrial broadcast DVB-T receiver. Background technique [0002] Mobile vehicles are important carriers of information, especially for public transport. In order to expand their advertising business, some entertainment media companies have shifted their attention to moving vehicles including taxis and buses, using these moving vehicles as carriers of advertising information, thereby creating a lot of money for both entertainment media companies and public utility operators. Economic benefits. For people who ride in vehicles, this mode of operation also brings benefits. It can not only pass the boring free time when riding in vehicles, but also obtain the product information they need. So kill three birds with one stone. [0003] With the development of information technology and ...
