Digital television has become well-known radio transmission

Today, digital television has become well-known radio transmission, most of the city's friends have a "set-top box", using a TV to watch digital TV. A small box, the value of three five hundred, or even three thousand, weigh feel very alone in the hands of Pu, with the box will be able to watch digital TV? As everyone knows, this box really a lot of knowledge, it's a single type of strike, you coal Friends Ye Hao, first came to suddenly see the friends it has, it can be seen several of them.

DM8000 HD Satellite TV receivers
Satellite TV receivers, commonly known as set-top boxes, is head of the TV box. Now say "now" basic digital satellite TV receivers in general, and then the "past" what is it used, of course, the analog satellite TV receivers. Then ground, cable transmission signal is analog, the first satellite television transmission is an analog signal. Compared with digital signals, analog signals are susceptible to interference, so the image quality is not good, and the analog signal to the frequency band utilization is low, a satellite transmission of a small number of simulation programs; digital signal is more stable, high image quality , high bandwidth resource utilization, transfer programs more. Burning faithful know, and now we are all domestic digital satellite television transmission. And since God in star No. 9 since the domestic set-top box business is thriving. SARFT end of last year's bid, it leads to the extraordinary forces of more than thirty companies, the companies have a lot of names, satellite TV receivers.
We look at digital satellite TV receiver types, free satellite TV receivers, conditional satellite TV receiver, digital engineering machines, one machine combination, as well as digital satellite receiver card (box), and so on.

May not be common digital engineering machine. Only in the cable television (CATV) works only with front-end systems digital satellite television receivers, commonly known as digital engineering machine, or also known as Digital Satellite IRD (Integrated Receiver Decoder, integrated receiver decoder), satellite TV receivers than the average large are 19-inch chassis.

Engineering machine features a variety of special
1, the graphic reception, can receive the stock market of graphic information, Beijing Garvey PBI DVR-1000 is such a satellite TV receiver.
2, TS stream output function, you can receive free TV programs or with CI card to receive encrypted TV programs at the same time, output TV program transmission stream (TS) and audio and video signals, which is widely used for digital cable TV satellite TV receiver works . Such as Jiuzhou the DVS-2018AS.
3, Pro-frequency modulation output function, the satellite TV receiver and adjacent channel modulator combined, can be directly used in the cable TV front end. Such as TDR-6080T.
Combination of one machine
Combination of one machine, by definition, combined with satellite TV receiver. Such as the one now on the market several mold machine, DVB-S / T one machine, DVR / DVB-one, DVD / DVB-one machine.
1, D-One (Digital / Analog Satellite Receiver) is the digital and analog decoding circuit combinations, with a tuner can receive digital or analog TV programs. Now no one could have used, after all, there are not any analog satellite signals. Such as Bai Wei DSR-2200.
2, DVB-S / T is the number-one satellite television satellite receivers and digital terrestrial TV receiver combination, compatible with two in the digital receiver system, commonly known as Combo (Combo) satellite TV receiver. Such as Yum 7885. There DVB-S/T/C one machine, you can choose to receive digital cable.
3, DVR-DVB-one machine is the hard disk digital video recorders or digital recorders and digital satellite TV receiver combination. Such as DreamBox DM7000S.www.myclickshop.co.uk
Digital satellite receiver card (box)
Very early time, there is a computer to receive TV programs, digital satellite receiver card (box) is to solve this problem. It and computer connections, satellite receiver with built-in PCI card or external USB satellite receiver box, with software installed on your computer to receive TV programs or IP information and other multimedia information.
1, PCI satellite receiver card, like the graphics card, sound card, as long as placed in the expansion slot on the computer motherboard, in the corresponding software installed on your computer, you can directly use the CPU control channel transport stream receiver card, and the demultiplexing and decoding . The use of a computer to receive TV programs in real-time recording, time recording, you can also preview multiple channels at the same time, even for time-shifting operation. Shao very proficient in computers like this receiver.
2, USB satellite receiver box, the same card as an external, can be directly through the USB (Universal Serial Bus) interface connected to the computer, just after the operation as a receiver card. Such as the PINNACLE PCTV 400E. Actually useful for USB computer link with the satellite TV receiver, the decoder can live TV program passed after the computer player. If NEOTION Box 1000.
