Help us with new technologies

Post by Sat2000 » Tue Jun 01, 2021 5:27 am

Hi

We are r&d company and we implemented some new technologies in STB that I would like to discuss. Namely, the functions of streaming, sat finder (with and without 3D lnb), diagnostics, usage without a TV set, and open Web API. I would like to hear the opinion of your group on what options are needed/in what countries they are needed/or what to develop to make them more useful.

We modify RTOS (Ecos) SW. The first option is sat finder option. You can watch videos here ( ) and here ( )

Questions:

1. Do you think the installation option is important for your country for final users and installers? Please tell your country in the comments

2. What do you think about the process?

3. Is 3D lnb useful?

The second option is diagnostics. We measure LNB supply current, operating mode of the power supply, 22khz, antenna angles (static and dynamic), TP Lock Error, LM, PER, RSSI, supply voltage at the output of the receiver. Right now the first part of diagnostics is ready. You can watch this here ( ). The second part will be a spectrum. It is needed to understand the type of attenuation and distortion. Detects overlapping GSM signals and other terrestrial interference from both 950 to 2150 MHz and 10 to 13 GHz. The spectrum also allows you to assess the cause of the insufficient signal. In the case of a crooked antenna, the beam is bifurcated, that is, several adjacent satellites can be received at one point. In the case of a cable with a different impedance, there will be a mismatch and standing waves that have a constant character. Third – fix-it-yourself instructions for users

Questions:

4. Do you think the diagnostics option is important for your country for final users or installers? Please tell your country in the comments

5. What is possible to add to the measurements and what is the final purpose for these measurements?

6. Do the installers in your country need to receive reports about satellite system conditions from users? Do users usually have a router or smartphone?

7. Do operators in your system make normal service to the clients? Or tell them to find problems by themselves?

The third option is streaming. After installation, you download the m3u list from STB and you can use programs like IPTV or IPTV Pro. The quality is the same as transmitted. You can add picons. We guess that this will be useful for DVB-T2 first of all (that means for combo model). But it can be used in the countries with large quantities of open channels, or with some channels which can be opened by usual Chinese boxes.

Questions:

8. Are FTA channels popular in your country? From what satellite?

9. Are there any channels in your countries that can be opened by usual Chinese boxes (and please tell me if there are non-paired cards like Conax). From what satellite?

10. How popular can be DVB streaming in your country?

The next option is the open web API. You can watch it here ( ) Everybody can modify our extensions/application or make their own.

Question:

11. Are there many web programmers and enthusiasts in your country who will want to modify SW on mobile devices?

And the last option is the usage without a TV set.

Questions:

12. Are there many places without good internet?

13. Does everybody in your country has mobile devices?

14. Do you think watching DVB on mobile devices will be popular?

Thanks for your interest in TVROSat!

In North America, C-band is used to broadcast most of the programming content, and quite a bit is FTA. The ideal LNB/Feed would need to tune as follows:

-3.6 to 4.2 GHz (linear and circular polarization)
-most active transponders in the future will be in the upper C band (i.e. 4 - 4.2 GHz) to protect against 5G interference, so you will need a good band pass filter over that range.
-some limited content is transmitted over 4.5 to 4.8 GHz. It would be nice if the oscillator for the mixer was selectable or programmable for this band range.
-lower Ku band used is 10.7 - 11.7 GHz (linear and circular polarization)
-upper Ku band used is 11.7 - 12.7 GHz (linear and circular polarization)
-Ka band range is 18 - 20 GHz (linear and circular polarization)


If you can combine all that into a single feed system (maybe call it the Ultimate Feed) that efficiently illuminates a large parabolic reflector with f/D ~ 0.4, then your feed will be the # 1 seller in North America!

For STB, you need:

-mpeg2/mpeg4/hevc
-qpsk/8psk/16apsk/32apsk
-SD/HD/UHD
-4:2:0 and 4:2:2


Ideally it would run a Linux type open operating system allowing the end-user to make their own modifications. A built-in spectrum analyzer (which you say you have) would be most welcome by the community for tuning their antennas. If you do all this and can process 4:2:2 chroma signals, your STB will be the # 1 seller in North America!

I suggest contacting our sponsor ([email protected]). He can tell you precisely what you need and he can help you distribute these products in North America.
