TBS5927SE

Those waiting for a 5927SE USB version with an S2X extension can now try it out.
The TBS specification lists the following features:

TBS5927SE is the successor of TBS5927, a professional-grade digital satellite TV tuner USB box with USB2.0 connectivity for PCs. s Beyond standard DVB‑ S2X/S2/DVB-S QPSK and 8PSK supported by ordinary satellite receivers, it delivers advanced professional reception modes including ACM, VCM, Multi-Input Stream, 16APSK, 32APSK, Multiple Generic Stream and Combined Single Generic & Single TS — functions unavailable on most mainstream satellite receiving hardware. Equipped with built‑ in hardware blind scan, it features fast automatic blind scan over symbol rates and carrier frequencies, greatly simplifying satellite spectrum exploration. A tristate MPEG TS output interface supports flexible transport-stream export. With dedicated TBS software tools, users can capture these special broadcast streams effortlessly. Official Windows BDA drivers and Linux drivers are both supplied for broad system compatibility.

Although the 5927se driver is incomplete for Windows, I've run a few tests that look promising. We still need to wait until we can use DVB applications on this tuner.
It’s a pity that the StreamReader file cannot yet be used in established applications; only DVB players can be used.

On Linux, the situation is better for the 5927se, and expectations may be met once Deeptho’s driver – which does not yet exist – can be installed for the neumoDVB app, instead of the TBS driver. I carried out an initial test with a symbol rate of 666 on 11465 H at 5.0 W, or with the RAI DAB streamer on 12564 V.

So what’s the problem? Not everything that’s written on paper holds true in practice.

Here’s a lower symbol rate: 11481 H, 542, 1/2-radio Nostalgie on Ubuntu 24.04.

That’s something we should be pleased about.

It looks an interesting replacement for the 5927. Do you know what demod chip is used? Any internal pictures to share and compare against the 5927?

The tbs5927se specification given at the start is actually that of the AVAlink 6162A demodulator.

The tbs5927se specification listed at the start is, in fact, that of the AVAlink 6162A demodulator. And I think that tells us something about this USB device we were expecting to perform well; I don’t know if it’s better than the 5927, but at least it gives us access to certain parameters not found on the previous model. And it performs well!

I hope some of the developers who visit us and help improve the performance of the applications they’ve developed will find a solution that comes close to what we achieved by replacing CrazyCat.

Hallo Satesco,

hast du noch weitere Tests durchgeführt?

Bist du mit der USB-Version 5927 SE zufrieden?

Without Crazycat’s StreamReader file, I couldn't test many applications, including CrazyScan. I limited myself to the TSReader, TBS Blindscan utility and a few DVB players, particularly AltDVB.

I’d also add that I think the driver for this device still needs some fine-tuning. And that’s hardly surprising, as I’m working with an early version of the driver.

Even without these DVB tools – the ones we’ve been using for existing cards for a long time (I assume you’re familiar with them) – the tests I’ve carried out with the 5927Se are promising.

One example would be locking onto muxes with a low symbol rate. I managed to lock onto symbol rates of 542 and 666 at 5.0 W on both Windows and Linux. I also tested 16-APSK and 32-APSK modes with no problems. DAB streams also play on Linux.
I hope a developer will take the time to draw inspiration from the StreamReader file and make it usable for many DVB applications. For now, this is the only thing missing: a library similar to CrazyCat’s, so the 5927’s potential can be fully utilised, as with established cards.

A few aspects of this tuner’s driver still need fine-tuning. I hope we’ll discover as soon as possible what this device can do once we have a fully optimised driver and the StreamReader file, which is the backbone, so to speak, of many DVB applications. For now, I’m exploring it step by step.

I can see that it seems impossible at the moment, so let’s keep our fingers crossed that someone will provide us with such an essential file for the 5927SE tuner.

Anyone who has purchased the TBS5927SE device can download the driver from the TBS website.
