IVTV with Toshiba Qosmio Notebooks.

Hi,

i'm trying to setup the ivtv-driver for the tv-receiver inside the Toshiba
Qosmio Notebooks. This notebooks have a special mini-pci card inside, which
is very similar to the Happauge PVR-cards.

I could provide some pictures of the card, but i think, attaching to this mail
is not a good idea... :)
Ok, on this cards there are following chips:
- "Conexant MPEG II AV Encoder CX23416-22"
- "Micronas MSP3455G BB V3"
- "Micronas DRX3960A H"
- "Microtune MT 2050F"
The last chip is a chip-tuner of Microtune
(http://www.microtune.com/products/pdf/MT2050_Tuner_IC.pdf), like on the
bt878-cards of Pinnacle and others. I think, this is the biggest difference
to the Happauge-Cards. In the tuner-module of the 2.6.12.2-kernel is already
the support for this tuner included(anlong with the MT2032 with number 33),
but in the tuner-module of ivtv there is only the older MT2032 included.
(BTW, why is ivtv using a special tuner module and not the one of the
kernel ?)

At www.toshiba.de (and also other websites of toshiba) could be a
windows-driver found for the card, with ivtvfwextract.pl i extracted the
firmware of the included .sys-file.

Ok, with ivtv-0.3.7b, the card is recognized as PVR-250 and the drivers seems
to start partly... but the many i2c-errors confuses me, maybe someone could
help ? Ptune.pl an ivtvctl seems to work, but when i use cat /dev/video0...,
i got no output.

I did:
modprobe ivtv tuner=33
and got the output in the syslog:

Re: IVTV with Toshiba Qosmio Notebooks. [In reply to]

Hi.

I still think, using the ivtv-driver for the tv-tuner of the Qosmio notebooks
of toshiba would be a good idea. :) So i collected some informations, maybe
the developers could need that.

The Qosmio series of Toshiba is a notebook with a build tv-tuner on a
minipci-card, which is quite similar to the Happauge PVR-x50. In all
notebooks (Qosmio E10, F10, F20, G10, G20) the same card is used.

So, maybe these are helpful informations and Hans or Chris or somebody else
say some words, if its possible to enhance the ivtv-driver to support the
Qosmio-Cards.

If it helps, i could provide a shell-acount on a machine, where such a card is
in use, because they are not seperate to buy.

I disasembled my notebook to have a look on the card:
Hardware:

A complete list of the chips on the board.

- Microtune MT2050
Chip-Tuner, converts the HF to the baseband-signal. It is detected by the
tuner-module in ivtv and used in some other bt8x8-boards.

- Micronas DRX 3960A
The IF-Modulator, it demodulates the baseband-signal to the cvbs-signal and
sound output.
I don't find which chip is used one the Happauge Boards instead. But i think,
there is only some short i2c-init necessary.

- NEC D64031
It does some "Ghostimage"-reduction on the analog cvbs-signal. There is a
i2c-control, but the chip is also used on some other bt8x8-boards.

- NEC D64011
That is the video decoder on the board. The Happauge boards use the SAA7115
instead. It converts the analog cvbs-signal to the digital signal. There is
also a i2c-control, maybe someone could got the command-list from NEC.

- Conexant CX23416-22
Its the MPEG-Encoder, like on the Happauge boards.

- Micronas MSP3455G
That is the sound processor, like it also used on the other bt8x8-boards.

On the board is also some RAM and i think a I2C-Eeprom, but they are below the
shielding-plate.

Ok, i hope, this could give some overview about the hardware and the signal
chain.

I think the biggest problem is the video decoder, but maybe i could get some
informations with a i2c-sniffer, when no datasheet is provided by NEC.

Software:

ivtv-0.3.7h starts quite nice, but lacks of support for the different chips:
I extracted the firmware of the toshiba windows-driver.

That's not enough, you need to have such hardware on hand.

With a datasheet you stand a reasonably chance of making it work. Otherwise it's
probably not worth the time.
