[linux-dvb] S2API - First release

[linux-dvb] S2API - First release

[Steven Toth]

Hello,

It's been a crazy few days, please forgive my short absence.

What have I been doing? Well, rather than spending time discussing a new 
S2API on the mailing list, I wanted to actually produce a working series 
of patches that kernel and application developers could begin to test.

Here's where all of the new S2API patches will now appear:

http://linuxtv.org/hg/~stoth/s2

In addition, here's is a userland application that demonstrates tuning 
the current DVB-S/T/C and US ATSC modulations types using the new API. 
(www.steventoth.net/linux/s2/tune-v0.0.1.tgz)

A tuning demo app? What? Obviously, tuning older modulation types via 
the new API isn't a requirements, but it's a useful validation exercise 
for the new S2API. What _IS_ important is..... that it also demonstrates 
using the same tuning mechanism to tune DVB-S2 8PSK / NBC-QPSK 
modulation types, and also has rudimentary ISDB-T support for any 
developers specifically interested.

This S2API tree also contains support for the cx24116 demodulator 
driver, and the Hauppauge HVR4000 family of S2 products. So those 
interested testers/developers can modify the tune.c app demo and make 
changes specific to their area, and try experimenting with the new API 
if they desire. [1]

Obviously, tune.c isn't intelligent, it's not a replacement for szap, 
tzap or whatever - it's simply a standalone S2API test tool, that 
demonstrates the important API interface.

QAM/ATSC are working well, the HVR4000 changes look fine according to 
the debug log (although I have no local satellite feed for testing 
tonight). DVB-T should just work as-is, but I can't test this for a day 
or so. I.E. I've tested what I can in the US but we might have a few 
bugs or gotchas!

If anyone is willing to pull the tree and begin testing with the tune.c 
app then please post all feedback on this thread. [2]

I've received a lot of good feedback of the original 2007 patches. I 
expect to start merging those changes of the coming days. Don't be too 
concerned that your changes are not yet merged, keep watching the S2API 
tree and they will soon appear ... along with a lot of general code 
cleanup (checkpatch violations)

I expect to catchup on my older email tomorrow.

Regards to all,

- Steve
[1] I'll need to review and diff any of the newer HVR4000 driver 
derivatives that people have been using, before merging those changes 
into the S2API tree.
[2] Remember you're going to need the cx24116 firmware if you're 
specifically testing the HVR4000.... but you probably already know that! :)

I imagine that there isn't really any need to use the S2 API to tune older
modulation types, because you just use the existing API if you want the
old style tuning.

However I would agree that if the new API supports both old and new style
tuning, then that is nicer for anyone writing a new app, as they only have
to code for the S2API, and get support for all tuning styles. Unless I too
am not understanding :)

Howdy,

Just to clarify things, in fact, BSkyB is indeed making rather
heavy use of DVB-S2, with -- based on what I've read and results
of previous `scan's (as I have no DVB-S2-capable tuner), two more
transponders recently or about to switch from DVB-S to DVB-S2.

If I am to trust my manually-added notes to my frequency list,
that is bringing the number of DVB-S2 transponders at 28E to
almost ten, more or less.

However, as I understand it, the specs from Freesat for the SD
receivers do not include DVB-S2 ability (or is it H.264, or both?)
and Sky SD receivers also do not support this (nor dynamic PMT,
thus the need for umpteen regional variants of ITV1 and BBC1
and not-so-many C4/+1) and as a result, pretty much lock the
broadcasters into a far less efficient use of the scarce spectrum
for the near future.

The existing HDTV Freesat/FTA services are H.264 over DVB-S, but
all Freesat-HD receivers will need to tune DVB-S2, and it is
likely that BBC-HD will in the not-terribly-distant future be
using a DVB-S2 transponder.  Likewise ITV-HD, C4HD when it makes
it to Freesat, and all the regular channels that get HD versions.

BSkyB actually makes the most use of DVB-S2 for DTH satellite in
europe that I am aware of, but these services are pretty much
exclusively subscription services.


I agree that due to compatibility with SD services, DVB-S reception
will be a necessity for quite some time to come in many markets.

Hello Steven Toth,

I was not pro for new DVBS2 API, but seeing now how fast the things are mouving, I think this is reale goodand cool, can you add  your API to stb6100 and stb08900 driver?

Late night, odd choice of words.

The new API is capable of tuning the old and new products. For 
application developers it's not mandatory to move all of your tuning 
code to the new API just to support all of your current DVB products.

The S2 API support is written to support every current and new DVB card 
we're likely to see over the next 10 years, it's flexible... I'm simply 
saying that application developers can slowly migrate their code to it 
... you don't have to move all of your tuning code to the new API in one go.

Correct, it's the developers choice.

Correct again, it supports old and new tuners.

Good news. I will test it with my cx24116 based cards (not HVR4000)

Thanks.

If you have any issues I'm on IRC, ping me - it could be something 
minor. I'm planning to grab a DVB-S generator today for some more 
testing this evening.

I will test it with the HVR4000.

Looking at the code in dvb_frontend.c I think TV_SET_TONE and TV_SET_VOLTAGE don't do
anything. Or am I missing something?

Let me put things a bit clear. The multiproto tree already supports
DVB-S2 and future modulations, with backward compatibility. Also all
STB0899 based devices are supported by the multiproto tree. Patches do
exist for the cx24116 devices as well. Once the API patches are in
kernel (a pull request is already pending) it will be easy to add in
newer devices as well.

If you need to use the stb0899 based drivers, you can simply pull the
tree from http:http://jusst.de/hg/multiproto

It is available -now- you don't have to wait for things

Regards,
Manu

My bad.

Pull again from ~stoth/s2, I fixed this last night and tested with a 
generator.

DVB-S is working fine. 8PSK and NBC-QPSK would also work - assuming you 
have the right tuning params (pilot etc).

Steve,

I have been tracking down the following bug which affects the LNB voltage. I now have
signal lock for DVB-S and DVB-S2 (QPSK, Astra HD Promo) with the HVR4000.

Regards,
Hans

Hans, thanks for fixing this. I've applied it the ~stoth/s2 tree.

Good to hear you're up and running with the HVR4000!

Steve
