So, i have writen a little tutorial to get the sdp-Files and some hints to get dvb-h to work, look at http://dvbh.kilu.de

Thanks, sgoerg

I already managed to get the sdp files from ESG, and found out PIDs and IPs, but still no luck. In Finland data is capsulated in IPv6 packets and I wonder if it has something to do with my problems.

THis is what I get with mplayer:

STREAM: [SDP] sdp:///var/lib/media/nfs/RadioNova.sdp
STREAM: Description: SDP stream descriptor
STREAM: Author: Ross Finlayson
STREAM: Comment: Uses LIVE555 Streaming Media library.
file format detected.
Initiated "audio/MPEG4-GENERIC" RTP subsession on port 10142
Increased audio socket receive buffer to 110592 bytes
Initiated "video/H264" RTP subsession on port 10140
Increased video socket receive buffer to 2000000 bytes
==> Found audio stream: 0
==> Found video stream: 0

and then nothing.

Maybe IP packets are not reaching mplayer. But I can see correct network traffic with tcpdump.

Attached files have have IP addresses and couple of PIDS for all Helsinki area channels. Zip file has ESG data files where one can extract sdp files.

USB host mode works on 770s; it's a lot more trouble to get working, as 5V power must be supplied into the tablet, but it has been done. No clue whether this would work on a 770, but host mode's not the problem.

Re: DVB-H on N800 - success
 
this is great news, I have a couple of DVB-T sticks, one freecom and one no-name, and I also have a power USB hub. I believe that there have been DVB-H trials in the UK, so I will need to do a bit of research to see if there's any coverage in my area. I live near, and work in, Cambridge, and there's quite a lot of mobile technology activity around here so maybe I will be lucky!

:) I NEED the last step in your tutorial too. Without that, I'm lost. But this is the most exciting this to come along since I was able to contact all my Skype contacts when that became available.

Great work!

The sticks work also with 3.7V, but then it takes about 500mA . But it is possible to use the internal battery (not the power from the usb connector) for some time !

@sgoerg

Is it possible to post .diff patches for fixed usb support iin kernel here?

sgoerg 2008-03-14 11:37

Re: DVB-H on N800 - success
 
You must translate the kernel with CONFIG_MUSB_PIO_ONLY=y in .config. If you would like to power the usb-stick only with a external battery - without a hub - then comment out the powercheck:

Btw. knows anybody more about the Nokia Mobile TV Receiver SU-33W (protocolls, availability,..) ?
