Now there is a power kernel which includes an USB OTG. Have anyone tested if there is possible to configure any DVB-T tuner to operate with N900?

I'm an active motorcyclist and sometimes I miss TV for news etc. and a connection is too bad for internet services but, at the same time terrestial signals seems to be just fine.

I could have more power from my bike's battery, so using an USB hub with a power supply wouldn't be a problem. I'm not a specialist under the hood of Maemo, so, what it would require to do this?

dvb-t streams might be too much for N900. Donīt really know about this but wild guess.

It will probably depend on the DVB-T stream. The bitrate used in dvb-T stream can vary a lot. Most countries use MPEG-2 streams and use relatively low bitrate streams. Since I have seen a N900 play a MPEG2 stream from a DVD drive, I think most DVB-T streams shouldn't be a problem.

There are tools to stream the DVB-T stream from a PC to the N900 over wifi. That way you can test if the N900 is powerful enough. It probably will be.

The driver for a DVB-T stick is bigger problem.
I tried a PCTV picostick, but compiling v4l with support for this stick didn't work on maemo for me yet, don't know why yet.
The stick is detected using the USB host kernel, so I think the N900 supplies enough power.

In the USB-Host mode topic I posted some info about what i tried:

unencrypted DVB-H from a DVB-H test in Berlin worked on a N810, so should also be possible on the N900. But DVB-H is available in much less countries, and mostly use encryption on the streams.

dvbh is available in my country and it has been running for free for some time now. i wish someone will implement it on the N900

So what do we need now?
  • how much power does an average DVB-T USB stick draw/require?
  • drivers for stick suitable for Maemo 5
  • application to operate DVB-T service (perhaps patch/add on for Media Player or MPlayer?)

Does anybody know how I could easily compile a new version of v4l on the N900? If I can figure out how to do that I can add support for my DVB-T stick.

I tried installing some developer tools on my n900, but I have a lot of problems compiling because of a lack of space.
I assume compiling in scratchbox doesn't have this limitation, but how do I make an installable package out of the new v4l instead of using "make install". I tried things like checkinstall, but that doesn't even work in ubuntu (probably because these are rather low-level files).

Step by step, on ubuntu I would clone a copy of the latest v4l trunk, apply a patch to add support for my PCTV Picostick, compile, install and copy the firmware.

Code:
svn checkout http://openee.googlecode.com/svn/trunk/ openee
hg clone http://linuxtv.org/hg/v4l-dvb
cp openee/recipes/v4l-dvb/files/v4l-dvb-as102.patch v4l-dvb/v4l-dvb-as102.patch
cd v4l-dvb
patch -p1 -i v4l-dvb-as102.patch
sudo make menuconfig
sudo gedit v4l/.config

CHANGE
CONFIG_DVB_FIREDTV=m
to
CONFIG_DVB_FIREDTV=n

make
sudo make install
sudo tar -v -x -f openee/recipes/v4l-dvb/files/v4l-dvb-firmwares.tar.gz -C /lib/firmware
Surely something similar can be made to work on Maemo and the N900?
anybody a suggestion on how to do that and install the result on my n900?

This guy with his pandora got DVB-T Working on it not to long ago, he was using a Digi Vox Mini Air DVB-T Tuner. He compiled the drivers himself. Here's the full thread.

Maybe someone can buy one and give it a shot?

download and install the sdk on your cophy of ubuntu, that will setup an n900 environment in which you can compile. I had one running for maemo4 but dont have one for maemo5.

here in the uk, the stock media player will not play dvb-t recordings as it does not have the codec, even with extra codec support. haven't tried mplayer.

you will also need a powered usb hub, as the dvb.-t sticks i have are very power hungry, so it's more than just dumping the v4l stack on there.

good luck
