Re: [linux-dvb] Implementing support for multi-channel
Hello, I was wondering if there's some info to find on how to implement (and test) multi-channel receiving? It's possible, because dvb uses streams and the driver is currently capable to filter one channel, but how can I implement the support of multi-channel filtering? Is there perhaps an open-source driver supporting this that I can have a look at? Check out the dvbstreamer project: http://dvbstreamer.sourceforge.net/ This allows multi-channel recording / streaming if the DVB device supports sending the whole transport stream (some usb devices do not support this). This works by sending the whole transport stream to the dvbstreamer program, then this program allows filtering out and recording separate channels from that stream as required. This isn't a driver level solution, but might provide the function you need. ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb

Re: [linux-dvb] Multiproto ???
A long time ago multiproto was said to be integrated in *near* future... to my great disapointment it still isn't, which is certainly not a good thing for the user at least... Could we hope to be *near* inclusion now ? In the meantime I am really thankfull to all who made multiproto available, and I hope the problems of the past could be forgiven. I would like to add a note to this, for those that haven't heard the BBC will be starting a new satellite service soon, spring 08 according to their website http://www.freesat.co.uk/home.php. This will be DVB-S2 transmissions including HD content, and will use the Eurobird 1 satellite situated at 28.5° east (from what I can find on the web). Once this service launches I imagine there will be lots of people (me included!) who will want to upgrade their Linux based media centres and therefore get HD content. As I understand it the Multiproto stuff is a pre-req in a chain required to get DVB-S2 working, so I expect that there will soon be a large number of people from the UK wanting to have this working so they can upgrade their media centres and get HD programs. ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb

This will be DVB-S2 transmissions including HD content, and will use the Eurobird 1 satellite situated at 28.5° east (from what I can find on the web). You may be right about this but so far everything I've seen suggests that Freesat will be DVB-S. I've not seen anything about DVB-S2. Do you have a reference for this? I cannot find the site I originally found, but it was a list of hardware specs for various Freesat boxes, and they were all S2. Looking around (digitalspy forums) it would appear that SD content is all DVB-S, but when they start the HD transmissions that will be DVB-S2 (h.264 IIRC, but again I cannot find a good reference). The old BBC site had more info, but now it is a flash marketing site :) ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
Re: [linux-dvb] Multiproto ???
Other questions: - what kind of hardware (other than DVB-S2 card) will be needed to decode the stream? - who are the 2% of viewers in the UK who can't see the Eurobird footprint? Tony (saving for a Sony FullHD 102cm screen) IIRC (and as of my other post I cannot find good reference atm). SD content will be DVB-S, the HD content will be DVB-S2 with h.264 encoding. That will mean that you will need a reasonably fast CPU as there isn't hardware acceleration of h.264 under linux yet (Video acceleration API is being worked on, search for VAAPI). I imagine that most transmissions are likely to be 720p at most so any modern CPU should have enough power. As for the footprint, the BBC trust has an obligation to make its programs available to everyone in the UK, with the phasing out of analogue transmissions I think I read somewhere that this is their only choice to ensure total coverage. ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
Re: [linux-dvb] Multiproto ???
The current BBC HD transmissions, prior to the official launch of Freesat are DVB-S, and broadcast From Astra 28.2E. There was some talk of a possible move to DVB-S2 at some time in the future, but I don't have a reference for this and haven't seen anything more about it in the last few months. AFAIK, all the current BBC HD transmissions are 1080i.

[linux-dvb] Dual tuner DVB-T
Hi all, I have a very small form factor PC there is just about space for one PCI card, so I could in theory fit a dual tuner card in there. I've looked through the wiki, but there isn't much data on which cards really work, so I would love some advice on what solutions actually work and people are using. There is the Nova-T 500, but in the wiki this mentions serious problems? Does this fully work now, streaming the whole TS, working with VDR etc? Or there is the DViCO Fusion HDTV Dual, it seems to have some problems though, can anyone using this confirm that it works with VDR, tuning while streaming, and streaming the whole TS? Other than that I am stumped, I could go with 2 usb tuners if there are any known good ones that will stream the whole TS? I was looking at the freecom one, but apparently that won't send the whole transport stream.

Don't even think about a whole TS, let alone two! Really? I've got cat 6 cabling in the wall and plans to upgrade my 100mbit switch to gigabit one, I would have thought that this was more than enough network bandwidth to stream two TS's. Just benchmarked disk to disk on my 100meg network, I can get approximately 4 megs a second (thats megabytes per second) transferring real data between two machines on my network (one being the media box that will be broadcasting the TS stream).

Looking at the front end status it never seems static, sometimes I get: Signal, Lock, Carrier, VITERBI, Sync, which all looks good. but other times I only get: Signal, Lock, Carrier, Sync or Carrier, VITERBI As I can see the dib0700 USB bridge in this stick deactivates the I2C controller during data streaming, so all I2C accesses to mt2060 (tuner) and dib7000pc (dvb-t demodulator) fail. Therefore you get I2C read fails messages from mt2060 and uninitialized (random) data for the frontend (dib7000pc) status. Unfortunately there seems to be no independent I2C gate control call in the dib0700 firmware... So.. .with this hardware restriction, having a working driver that behaves like the other devices is going to be hard? Could a fix for this be to ensure that in the driver if a tune request is sent, the driver stops streaming, tunes, then starts again? At the same time the front end status could be cached from just before streaming is started and this cached data returned when requested, rather than going to the device itself? Both of these seem a bit like a hack to me, but seem like they would bring the driver closer to behaving the way apps like VDR expect. If there is not way of accessing the real data, then at least a cached version from before streaming was started would provide some data. ___ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
