[linux-dvb] bttv twinhan thoughts
G'day all, This is not strictly related to dvb I guess, more of a bttv issue. In windows, when I insert my twinhan card and load standard bttv drivers it does not work, but it also does not hard lock the machine. In linux, if I forget to tell bttv the card type, it hard locks. I'd love to see this behaviour change as it's a major usability issue. Now I realise the card is a pile of steaming excrement, but it's also cheap and unfortunately becoming quite widespread, plus when it does work, it does its job quite well. This has just arisen again as I went to play with knoppix 3.3 which now probes for bttv cards on boot and because of this hardlocks the machine. I have not found a way to tell it not to probe for bttv. Thoughts? I'm willing to invest some more time in hardlocking the machine debugging this, but I feel it is going to require some changes in the bttv driver which I'm concerned will impact other cards.

Basically you must not touch any of the video registers, which is impossible to do without breaking the analog cards, at least the ones which also don't have a PCI Subsystem ID. Unless you find some way to detect the card without the ID ... This is the bit that has me wondering. If it's a standard connexant 878 chip on it (and it appears to be) then there must be some strange setup that causes it to lock the PCI bus.. This is the bit I'm wondering about. Why does the windows driver not do the same.. Perhaps it's time to get the dissasembler and debugger out again.

The red card is supported by drivers in Linux 2.6, except the conditional access module. Twinhan have binary drivers for Linux 2.4, but they don't implement the standard API, so few programs are likely to work well. Many programs might work in a limited way if you first tune the card using their example programs. I'm afraid no standard linux dvb apps will work at all with the standard twinhan drivers. They won't. What is possible is to tune the card to the desired channel and read the TS from the device with any program. Data transfer with the twinhan drivers is done with a very large buffer and special ioctls, plus the non-ci card generate a standard 188byte packet TS while the -CI cards generate a 206(? it's been a while since I had my head in there) byte packet that needs to me slightly truncated before decoding the TS. 204, it's got something to do with error correction. -- Måns Rullgård [EMAIL PROTECTED] -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with unsubscribe linux-dvb as subject.

This might be useful except that the tuner has already done the error correcting and thus they are redundant. Like I said, it's been a while since I had my head in the code. You can only read the TS from the device for non-CI cards, otherwise you have to post-process it yourself first. I use mine in concert with mplayer and my projector as my main TV, so it gets daily use. Does not mean it's not a pig of a card though! I have just ordered some hardware to help me with my quest for getting the CI working.. hopefully in a couple of weeks I get some time to start.

[linux-dvb] Running a DVB head-end with free software
Hi! I'm wondering if, using the software developed by the Linux DVB group and others, one can run an head-end station which can produce a DVB stream suitable to be aired for reception via either satellite or terrestrial network. Software support for DVB for Linux allow almost anything one would like to do when receiving TV programming (watchin, recording, time-shifting...), I'm wondering if the same is true (or could be easily made true) for TV broadcasters, so that the only thing you need is a modulator, an amplifier and a transmitting antenna?

It's the fastest zapping channels I ever tried, and after 1 hour and 30 minutes uptime, every thing seems to be perfect (even with xawtv on G550).

[linux-dvb] b2c2 with opensky
Hi I am desperately trying to get my sky star 2(B2C2) card to work on linux kernel 2.6.5 with open sky service. Apparently everything is working fine. First, I load the B2C2 module. Then we load the front end module which is detected to be stv0299 . Then we use dvbtune to lock the frequency and create the dvb0_0 interface.The locking displays all the parameters to be fine e.g FE_LOCK. Lastly, Ifconfig is used to set a dummy ip and the mac address(given to opensky by us) of the dvb card. After that we connect to the dial up and login to open sky services using lynx http://sdr.eutelsat.com. All the information displayed is correct i.e the ip address of our dial up ,the mac address of dvb card and the pid. Then we set http_proxy variable to the opensky proxy to start recieving data from satellite. We do not get any data from the dish i.e 0 bytes. Can some one please guide us. Thanx in advance.
