Hi,

unfortunately there was no mailto: link available for Daniel Caetano - because I wanted to suggest to give a try for T&V Happy Player.
TVHappy is the application I use and I am more than staisfied with this little piece of great software from russia. I have a Hauppauge WinTV/PCI card with the BT848 chipset on it (the "ancestor" of BT878 ) and went through many of the possible applications and drivers for OS/2. Some day, I found Vadim Rumyantsev's program and was very pleased by the fact that it uses only 1 driver and 1 application which only require unzipping, the appropriate entry in config.sys and you're ready to go.
The only drawback it has is that there is no "full-screen" picture available and some minor issues with useability - but in the other hand it consumes almost nothing in CPU cycles. It's absolutely worth trying out!
It's not freeware (10 Euro I think) but checking it out is for free!
This is the link: http://os2.in.ru/software/projects/happyplayer/index_e.html

I recently tested T&V Happy Player... It indeed looks good, but it has major drawbacks when compared to other programs. One you had mentioned was the "no-full-screen". The other is the interface, which is poor (everything has to be done using keyboard). This is not a big issue, but it should be improved in this way.
Anyway, the biggest issue I had with it was the fact it supports european PAL and SECAM, but no Pal-M or not even NTSC... which bring me no options to see anything.
I had written for the authot too, but the only author that answered my e-mails was Stefan Milcke, from BTTV, which is doing a superb work on translating the original Linux drivers for OS/2 (inclusing LXAPI32, which can be used to easily port many other Linux drivers to OS/2).

I hope I can write a new version of the article in a near future, including information about T&V Happy Player and, I hope, news about other Video/TV Apps too... (^=
Regards,

The article states that EmperoarTV is targeted to BT8x8 based cards. This is wrong ! The Hauppauge PVR250 / 350 cards use the CX23415 or CX23416 hardware MPEG encoders http://www.conexant.com/products/entry.jsp?id=9
These have nothing in common with the BT8x8 chips. So there is absolutely no wonder, that the driver does not even install on the PCTV.

Indeed? My mistake then... (^=
I thought it used BT8x8 because of BT drivers (from Linux), which supports the family says it supports

Suppported cards:
Bt848/Bt848a/Bt849/Bt878/Bt879 cards

And in the description of which board of each vendor uses those chips, we have:

Hauppauge
---------
many many WinTV models ...
(...)
WinTV PVR
WinTV PVR 250
WinTV PVR 450
(...)
983 WinTV-PVR-250
883 WinTV-PVR-PCI
993 WinTV-PVR-350
893 WinTV-PVR-USB

Sorry if I am mistaken, but I think Linux BT drivers are wrong then. But I think it's more likely Hauppauge would not like to see their driver being used with other hardware not made by them (nothing to complain about it).
Remember that MPEG encoders and video-in are different things, that uses different chipsets. The TV/Radio Tunner is an entirely different thing also.

The list is definitively wrong. The only card in the PVR series, that is partially supported by BTTV is the PVR-PCI "classic" i.e. the one without any number. But AFAIK, neither audio nor the MPEG section is working. All others (BTW, there is no PVR 450), are not supported by BTTV. There are separate Linux projects that deal with these cards. For example Ivytv for the PVR 250/350, which appears to be the most advanced. There are also two other projects dealing with the PVR-USB and the PVR-USB2, respectively.

Ok, ok... forget about it. It's just not worth this discussion.
I do not have Hauppauge baords to look at and the only info I had was this doc.
I just was trying to state that MPEG DSP, video ADC and TV Tunner are different things and BT driver is basically just to address the video ADC one, not the others (even if it covers some TV Tunners too, using different modules). It seems the chipset used in hauppauge PVR boards is an integrated "all in one" chip... there is almost no tech information about it on the net.

Yes. On the PVR250/350, these is no spilt between "regular" TV and MPEG operation It's all done in one. That - together with the documentation situation - made it so hard to write a driver for it...

Rudi,

Emperoar -AFAIK- supports the WinTV PVR 250 and -350 models... but there are some other vendors of similar cards (tuner chips + mpeg en/decoder chips) which seem to be cheaper than genuine Hauppauge models...
Have you got any idea what people should look for in technical sheets to find out if a card (other than Hauppauge) is supported by Emperoar? Did you hear of any success stories with other brands?

TIA
Thomas

As author of TVShow i wish to say some words. First of all, my acknowledgement for good words about my program. Second - sorry for not reply to mail. I just returned from business trip and not read my email's.
Next, some technical issues. TVShow currently support only AverMedia style remote controls, where remote command codes set some bits on bt878 GPIO port. Not Hauppauge style (where remote recdeiver accessed via I2C bus), not Pinnacle style (with remote plugged in plain com port). For Hauppauge style some work done, but simply no time, almost all my free time utilized in firewire driver set development.
Next, about NTSC and PAL-M. Support for this standart is written only buy docs, no real testing done. I did'nt have any source of test video signal. Some times ago NTSC support was broken and disabled, later it re-enabled but i forget to mention it in docs. Mark it in my to-do.
Next, about cards. Theoretically, tvshow must work with almost any bt848/848A/878/879 based tvtuner without advanced sound decoders like MSP34XX chip, only Hauupauge card with MSP3415 supported and tested (Hauppage WinTV Primio FM mod 693) . But user must describe lot's of constants for programming tuner, sound mixer and remote controls. See [usercard] and [usertuner] sections in video.cfg. As supported i list cards only i test by myself or got confirmed reports what all working ok. Getting such constants not easy task for user, but i offer my hel, i can be accessed at doctor(at)cps.com.ua and doctor64(at)dochome.homedns.org , doctor64(at)e-mail.ru

There was a PVR450 model listed on the net 1 ot 2 months ago. Never saw the board - just a specs page on Hauppauge's or one of their distributor's sites. The page though, had specs that were apparently a re-write of the PVR-250 page with only some of the info updated to reflect the PVR-450. Perhaps the 450 never came out (and hence the page never fully updated with the appropriate info)? There are still "Supported Hardware" lists that show this card, but no longer seem to be vendor/manufacturer pages up for it. Dunno what the card differences were supposed to be...

Doc 64,

Thanks for the answer... I received your e-mail and soon I'll be answering you and probably I can help you to improve TVShow. (^=

warpcafe (04 Oct, 2004 10:01):
Emperoar -AFAIK- supports the WinTV PVR 250 and -350 models... but there are some other vendors of similar cards (tuner chips + mpeg en/decoder chips) which seem to be cheaper than genuine Hauppauge models...

There are some similar cards from other vendors, but we don't know if any of them are working with our software. The most promising was the Yuan MPG600. But unfortunately the current hardware revison uses a Philips SAA7174 instead of the SAA7115/MSP44xx combo for video A/D conversion and TV audio processing. I have such a card here and there is already some code for it in our driver, but it's not working. Since Philips has not published the specs for the SAA7174, I decided to move on to other parts of EmperoarTV. I may dig deeper into that again, once I get access to the specs. (If someone can help out, I'll appreciate .
Also, about 2 weeks ago Hauppauge U.S. announced the PVR150 and PVR500 boards. But the bad thing is, that they use another "non-disclosed" chip (Conexant CX25843) for the same purpose. So unless I find a way to get hands on these specs, I cannot support them.

And answering your question about the chips to look for: We currently support the CX23415 and CX23416 hardware MPEG encoders together with the SAA7115 video digitizer / scaler and the MSP34xx and MSP 44xx sound processors.

Rudi,
thanks a lot! This is a perfect answer - now I am able to check... the only problem (as usual?) will be to find a manufacturer who made the efforts to post the appropriate specs in the data sheets or manual...
Nevertheless - thanks! This was what I wanted to know.

Greetings
Thomas
