Good morning all

I've had a motorized satellite set up (2 LNB's) installed this week and one part (Technomate M3 for 4:2:0 feeds) is working all fine, and now my next task is installing a blindscanning software, DVB player and relevant plug ins on a PC so I'm able to watch the 4:2:2 feeds, but I need some advice if you would be so kind please.

The PC spec is decent (Windows 10, Intel i7 9700, 32GB RAM, Nvidia GeForce GTX 1060 6G) and I have installed a TBS6903 card and drivers and they are showing in systems so should be working ok.

What would be the best and easiest way for me to go for software for the PC? I'm new to satellite so am looking for the most user friendly and stable combination if possible please.

Ultimately my aim is to find the feed and key on this site and be able to watch the game fairly quickly.

Thank you

Dan

Personally, as latency is an important factor, I would go for EBS Pro and output the scanned frequency you want to VLC.
Makes sure the buffers and latency settings are minimised in VLC. There is plenty of help on how to edit settings in VLC on the internet, google should bring them up.

I have found that DVB Dream can be glitchy at times and sometimes needs to be restarted. As far as I am aware, it has not been updated for several years by the developer.
EBS Pro seems to get updates at the moment and VLC certainly does. With VLC you do not need to worry about codecs as they are part of the install.

Finally, both EBS Pro and VLC have the options to accept biss CW so no worries about not being able to view biss encrypted feeds.
Again, there is plenty of information on the internet about how to input biss CW into these apps.

As regards latency, in tests I have found that EBS Pro to VLC when correctly configured is practically the same as watching on a TV from a receiver. Any difference is below human reaction time.

Moonbase, what can I say, thank you so much, this has been a great help.

It took a few hours but I managed to get VLC playing through EBS and got the latency down to a point where its very negligible vs a satellite channel. All I need to do is demonstrate it on a 4:2:2 feed and add a key in and I'm where I wanted to be.

Thanks again, really appreciate your help on everything. If ever you're in the south of UK I'll happily buy you a beer!

Regards

Dan

I am in the South of the UK in leafy Surrey, just inside the M25.

For me, DVBDream is too flakey and unreliable for something as critical as betfair.
A good internal TBS DVB card for scanning via EBS Pro then sent to VLC is the most reliable and low latency solution I have come across for 4:2:2 feeds, apart from an Ericsson RX8200 receiver.

@moonbase

Next door to me, I'm on the Surrey/Kent border. Nice and leafy here too! What area you in?

Its working perfect for me, just restarted both my satellite and PC and checked both out side by side and I couldn't notice any latency. I'll check a key out on a 4:2:2 feed later this evening

Had success with an old technisat 2 Dvb card quite a few years ago now and I don't know if it works with EBS Pro .
I'm now thinking of getting an updated Dvb S2 card for 4:2:2 feeds.
Can you recommend a TBS Card that works good with EBS Pro.

All TBS based cards work fine with 4:2:2, because they just demodulate the signal and the muxed stream is demuxed and decoded by software. So it doesn't matter if 4:2:0 or 4:2:2 is broadcasted. The basic software which is used is FFMPEG (VLC bases on FFMPEG). The main problem you have is that broadcasters use MPEG4 10 Bit High Profile, which is not supported by any commecial GPU (only Matrox made a special GPU for professional usage). So if you like to decode or transcode MPEG4:2:2, you need a powerful CPU. On my AMD Ryzen 9 3900X 12-Core Processor, 1 Thread is needed just to transcode 1 MPEG4:2:2 stream to MPEG4:2:0 in realtime. What I do practically is to use a standard enigma 2 receiver, do a blind scan on a specific satellite (or use the feeds finder plugin), tune to a feed, if it's encrypted, use C8 finder python script (gets the c8 key out of MPEG TS packet), forward c8 key to local CSA server, get the CW back, insert it in Softcam, forward decrypted stream to my linux PC, which automatically starts transcoding from 4:2:2 to 4:2:0 (FFMPEG) and sends it back to enigma 2 receiver, where you can watch it or stream it to anywhere else.

I send the picture from the PC to the monitor via hdmi using a splitter where I also have a Technomate M3 plugged in. But I’m pretty sure you can run a cable from the PC back to a decoder

Have a look on the TBS website, the 6903 states system requirements and includes Linux

Hi,

Do you have the TBS6903 or the TBS6903-X?

I notice from the pictures they look slightly different with some that have a fan

did you get this working with a key on 4.4.2?

Thanks

I have both 6903 and 6903x.

For the fan, it depends which version of the 6903x it is. Not all versions had the fan .
The 6903 does not have a fan.

Thanks buddy,

whats the difference? i basically want to use a sat card instead of the rx8200 receivers but not experience the latency issues also. which card would i need

thanks

Personally, I would use a TBS6903 and not the TBS6903x.
The speed of the blind scan in Windows with a TBS6903x is slow

What makes you think a TBS6903 card will have reduced latency compared to an Ericsson RX8200?
If you consider the process in getting pictures from both options:

1. The RX8200 will output direct to an SDI monitor or to a TV using an SDI to HDMI converter.
2. The TBS6903 needs to send the RF signal to an app which onward streams to VLC for viewing. This can add sub second latency, depending on how the app and VLC are configured.

The advantage of the 6903 card is that is has blind scan functionality which is absent from an RX8200
The 6903 card in a PC might also be easier to use, an RX8200 has no onscreen menus and no remote control handset.
