Company’s headquarters are located in Shenzhen (China). DVB-S/S2 devices Prof are being tested with the help of satellites Astra, Hotbird, Sirius and others.
The Prof Tuners Group production is well-known for its high quality and operation reliability. All DVB-devices are produced from high-quality components at the high-technology circuit boards manufacturing facilities in China (Shenzhen). The circuit boards go through the whole testing cycle and presales preparation before releasing them for sale.

DVB represents a hardware-software complex device. It means that both PCB and software are used for the required task perfomance. PTG Engine software kernel consists of drivers.
According to many users, drivers are deemed as “configuration files” and nothing else. Such files make the computer able to identify a device. User imagines, that having plugged the device and ran a computer, he/she had to install the “configuration file” usually called “driver” to let the system see a new hardware, because until that, the operational system cannot work with the device.
In fact, driver does not configurate the device but drives it, which means operation of DVB-devices (including chips) on a basic level. All the modern domestic DVB-cards have a  “program processing of the flow” parameter.  This means that such DVB-cards receive a satellite signal (i.e. PCI, PCI-E, USB traffic flow) and transfer the data to the computer operational memory (through PCI, PCI-E, or USB interface). Driver program carries out the main data processing.

Unfortunately, the method applied to standard definition television(SDTV) is not applicable in such a case. You will not achieve an appropriate image quality having just plugged DVB-card into computer slot and set up “some” codecs for h.264. Perhaps, your DVB-card will start operate but either an image will be displayed separately from sound or it will be blurred and indistinct along with skiping the frames and even whole separate scenes.
This article is written in order to focus the users on that why it is so necessary to use h.264 hardware codec to receive satellite TV in high definition. The following explanations will show you that hardware codec allows the satellite TV receiver users to get better image than software codec does and fully enjoy the quality of high definition.

So, you already have your DVB-card installed on PC or connected via USB-cable (of course, you had followed all the operation rules of the device and performed all the actions when the power was switched off) After that, you have installed the latest DVB-card driver. And possibly you already have watch the satellite TV with the help of DVBDream or AltDVB. Now you have decided to make the single-sided (simplex) system for satellite Internet reception through such multi-media device as DVB-card. If the antenna is already tuned to satellite desired by you, the converter is connected to the antenna, the cable links the converter with DVB-card and you have subscribed to the correspondent satellite provider, then you only have to install an additional software and set it up correctly.

Upon the demand of authors of satellite theme devoted articles, the "secret statistics" box as been added. This statistics allows you, for example, to identify the stream loading. It can be useful if you want to write a satellite providers reviews, and make ratings of providers and transponders.

 The "secret statistics" window is opened by pressing the CTRL+T keys. At that moment, the IP DATA window shall be active.

AltDVB: was the absolute leader. It has the fastest scanner from all DVB players in tests. This success is mostly because of great Prof device interface Dev_Prof.int written by Prof Tuners Team.

DVBDream 1.4i: scanning was slow to compare with other DVB players. Also at my configuration it was more unstable. When scanning Astra it hung up at 12,012V (PsiParser error) and I needed to scan again. Also it hangs up almost always when I tried to close it (window disappears, but dvbdream.exe stayed in the process manager for next 5-8 minutes. I was not able to cancel this process - 5-8 minutes to wait, until it closed on its own). Also I had tested DVBDream with original BDA interface, and BDA_ALL interface made by ScanMan. First was even worse than version from Prof, second had similar results. At the end I even tried to DVBDream 1.5 beta 7, but that also didnt help - DVBDream scanner was not very fast or it just failed at my configuration.
Also to be clear: DVBDream had no problems with locking frequencies etc. Speed problem was caused just by the scanner because it (in my opinion) analyzed PMT table too long. White progress bar in PMT field goes to the end but anyway DVBDream waited for PMT timeout and because of that scanned every frequency, even if lock was in less than 100ms was done in not less than 5-6 seconds... That is the reason why scanning in DVBDream was slow. 

SmartDVB: very good result, scanning is fast and very precise. 

ProgDVB: slow, slow, slow... But that was not a surprise for me. It is just slow when scanning with any DVB card. But channel switching is blazing-fast! ProgDVB doesn’t have a transponders editor built in. It updates frequencies when scanning by obtaining necessary data from Transport Stream of other active frequencies. Because of that in fact ProgDVB started with 99 transponders on Hot Bird but finally updated this value to 105. Similar was on Astra - from 83 to 85. 

DVBViewer: good fast scanning, also many options, extended but easy configuration, very stable.

All DVB players were tested with standard settings. There were no changes made with timeouts for tables in DVB Transport Stream.

CE marking (also known as CE mark) is a mandatory conformance mark on many products marketed in the European Economic Area (EEA). CE abbreviation stands for conformité européenne, French for "European conformity".  CE is affixed to a product on a sole responsibility of manufacturer, and declares that the product meets the safety, health and environmental requirements established in EU.

It should be noted that the RoHS doesn't cover the batteries. However, in Europe, batteries production is regulated by the Battery Directive (91/157/EEC[4]), whose scope has recently been increased and approved in the form of the new Battery Directive, which highlights the environment protection from the negative effects of the waste contained in batteries. It also contains an industrial, automotive, and consumer batteries recycling program, significantly increasing the share of manufacturer-provided waste collection sites up to 45% until 2016. It also sets limits of mercury and cadmium at 5 ppm and 20 ppm reapectively, for all batteries, except those used in emergency, medical, or cordless power-tool devices.[6] Though it does not setting quantitative limits on   nickel, nickel-cadmium, lead, and lead-acid in batteries, it indicates a need to restrict these substances and ensurre the recycling of up to 75% of batteries containing these ones as well as there are provisions for marking the batteries with symbols regarding to metal content in the battery and recycling information.
