Hw capabilities of the HVR-2200
**a repost because of earlier issues in getting emails to the list**
Hi Kernellabs or anyone involved with driver development of the HVR-2200...
I know this is a loooong way down the priority list of features to be added, if ever! But I'm wanting to know if the *possibility* is there 'hardware-wise' for the following:
1) h.263/mpeg4/VC-1/DivX/Xvid hardware encode of A/V-in
2) Component input for the A/V-in
3) Hw encode bypass for A/V-in
4) Is Hw encode purely for A/V-in? (hauppauge's site suggests otherwise but it may be a typo)
5) If not then questions 1) & 3) also apply to RF-in!
Here are the reference cards spec sheets again:

http://www.picamatic.com/view/5094373_75016207_P2/
I would be proactive in providing feed-back (as needed) for the dev. of such features.
Most Sincerely,

Attention Kernellabs devs,
I've deliberately delayed these two posts as Steve mentioned he wouldn't have time to respond for at least 1wk.
It's now been almost two weeks, do you think you might have 5-minutes to spare now? I realise you might not "know" the answer to some of my questions yet!... :-D
All the best,

The only reason I suggest this is because it'd be nice to have the option to offload encoding to some other device or to 'soft-encode'.
Of course demand for such functionality would prolly be the lowest, so it's understandable if it's the last thing implemented, if at all.

It's not feature Hauppauge supports on the HVR2200 today. I have a suspicion this may change but I'm neither confirming, denying or announcing anything. It would make sense to officially support component cables on the HVR2200 since the silicon supports it. If/when it does I'm sure it will be mentioned in the forums or on the HVR2200 product packaging.

Raw analog TV isn't a high priority feature on my mental check-list. Analog TV via the encoder is much more interesting and applicable to many people.

So I garner from that, that you don't intend to add support for anything (including extra encoding abilities that they don't support in Windows) unless Hauppauge officially does?

No, I was referring specifically to your component 'are you sure?' question.
I've said many times on and off this mailing list that I'd like to add support for all of the encoder a/v codecs, regardless of the windows driver and it's capabilities. Timeframe for this is unknown.

Hi Steve, when you said this is not a feature Hauppauge supports. Did you mean it's not fully enabled physically in the PCB... Or is it just something they need to add support for in the driver? If the latter do you know if their policy has changed or is about to?

The current driver supports DTV only. I have no ETA for analog on the HVR22xx driver. If you need analog support then the HVR22xx isn't the right product for you.

I don't need analogue for tuning purposes but for A/V-in it'd be mighty handy.
If you've got anything that's very rough I'm happy to be your lab-rat?
Do you know of any dual hybrid DVB-T tuner cards that do have functioning A/V-in, or should I forget such devices for that purpose?

The features of a given piece of silicon do not always match what a company has ultimately licensed. This is especially true for things like codec support which can have significant royalties that have to be paid. Hence it's possible that while the chip *in theory* could support some particular codec, that doesn't mean that the firmware that ultimately got licensed has the necessary support.
Regarding component support, it's entirely possible that although the chip supports it, it may have been cost prohibitive to put the supporting hardware on the PCB. It's ultimately up to the product vendor to decide what subset of the functionality on the reference design to ship with.
Of course, everything I said in the above is complete speculation (based on my own previous experience working for a company that makes hardware), as I have no actual knowledge of why they chose to take the approach they did.
