Embodiment 1

[0026] Example 1 as figure 1 As shown, the present embodiment is a 5-in-1 TV receiver capable of receiving ATV, DVB-T, DVB-C, DVB-S and DVB-S2 standards, and these systems almost support all basic TV systems in Europe. After such a TV receiver leaves the factory, it can be used in almost all places in Europe without modification, and the TV signal reception can be completed only through the internal software identification of the TV receiver. The main structure of the television receiver of the present embodiment is as figure 1 Shown: Including the receiving port, tuner and main processor, the receiving port receives different TV system signals through the tuner to generate intermediate frequency signal input to the main processor for processing, the receiving port includes receiving DVB-S and DVB-S2 SATELLITE port for TV signal, AIR port for receiving DVB-T TV signal, CABLE port for receiving DVB-C TV signal and ATV port for analog signal. Up to the company's EDS-10210FNOHA...

Abstract

The invention discloses a multi-standard television receiver, comprising receiving ports, tuners and a main processor, wherein the receiving ports receive different television standard signals; the tuners modulate the different television standard signals into intermediate-frequency signals and output the intermediate-frequency signals to the main processor for processing; the receiving ports comprises an SATELLITE port for receiving DVB-S (Digital Video Broadcasting-Satellite) and DVB-S2 television signals, an AIR port for receiving DVB-T (Digital Video Broadcasting-Terrestrial) television signals, a CABLE port for receiving DVB-C (Digital Video Broadcasting-Cable) television signals and an ATV (Analog Television) port for receiving analog signals. The technical scheme of the invention contains ATV, DVB-T, DVB-C, DVB-S and DVB-S2 so that almost all European basic television standards are supported. With the five-in-one design, the requirements of different people in most European countries can be satisfied.

Description

technical field [0001] The invention relates to the field of television reception, in particular to a television receiver capable of receiving television signals of different systems and a television signal reception method. Background technique [0002] At present, the mainstream TV systems mainly include: ATV, DVB-T, DVB-C, DVB-S and DVB-S2, etc. All European TVs use these systems. [0003] ATV refers to analog TV signals, which are rarely used at present, and DVB is the abbreviation of Digital Video Broadcasting, which is a series of internationally recognized digital TV open standards maintained by the DVB project. DVB system transmission methods are as follows: satellite (DVB-S and DVB-S2); cable (DVB-C); terrestrial wireless (DVB-T); handheld terrestrial wireless (DVB-H). The main difference between these transmission methods is the modulation method used, because the requirements for the frequency bandwidth of different applications are different. DVB-S using high-f...
