    There are standards. Windows Media Player is a de-facto standard. And ETSI has published TR 102 033 on this (attached), which is a framework for delivering DVB over IP.


    There are many TV stations offering the possibility to view them via internet on Windows Media Player. If it is standardized enough to view them all via Windows Media Player it should be possible to write something universal for Linux as well. The only problem I see that the Dreambox has not enough processing power to do the video decoding in software. That limits us to MPEG-2 on the DM7025, but in the DM8000 we have MPEG-4 and Microsoft WM9 in hardware as well.


    I believe most programs transmitted via internet are completely open. No digital rights management is used.


    Currently the first providers of TV over IP are popping up. KPN in the Netherlands offers a service named "MIME" over ADSL, offering some 90 different TV stations. I guess they are using something based on the above ETSI framework.


    I understand this is not a minor thing one could implement in a few days. However, receiving TV over IP has the possibility to become the next big thing. For Dream Multimedia it would be a good idea to be part of that.


    My dream is that with a Dreambox I can watch content from different sources (DVB-S, DVB-T and DVB-IP) on a single box with a single user interface. Ideally, when watching TV one should not even know how the program gets into your house. With such a product, even your mother-in-law could watch TV via the internet.

    Would it be possible to create a virtual NIM (Network Interface Module) for watching IP TV? This NIM should be able to tune to URLs instead of tuning to satellite transponders. Enigma 2 should see such a virtual NIM as a 3rd NIM next to the 2 DVB-S/T/C NIMs.


    It would be great if with such a virtual NIM one could watch to everything one could watch with Windows Media Player.

    Thanks. If we can be helpful with any additional information, please let it know. Has Dream Multimedia already succeeded in reproducing the bug?

    You shall not cover the LNB. Put a wet cloth over it. That way it is very easy to reproduce without waiting for rain.


    The LNB shall be covered enough to have interrupted video, but not enough to stop it completely.


    To the Dream Multimedia developers I would advise to use adjustable coaxial attenuators instead of a wet cloth. I am sure your radio engineers do have some.

    It can still be a software problem. Poor reception can corrupt e.g. the entitlement management messages, which could cause a software module to crash. If your reception is OK the messages do not get corrupted and the software does not crash. Also timing can change if reception is poor. This can trigger timing related bugs in the software.


    I have myself experience in the development of DECT telephony. I can assure you there are lots of software problems that only show up under specific reception conditions. These problems are the most difficult ones to find. But they are real problems which have jeopardized multi-million-dollar projects.

    For me it is pay-TV on DVB-T (KPN Digitenne for EUR 9.95/month with Conax CI) plus FTA on DVB-S. This combination offers me a super package which is better then any single provider offers.


    The great thing about the Dreambox 7025 is that I can combine it in a single receiver and put the DVB-T and DVB-S channels intermixed in a bouquet list.


    To me the tendency of pay-TV providers to force you to use their receiver is a horror. I would like to combine the receiver I like with the TV programs I like. This is for me the main reason I drop UPC cable TV. One can only watch it with the UPC MediaBox supplied by UPC. It is a horrible receiver in which one cannot even put the channels in the order one likes, and which makes several restarts a day due to bugs. If hacker software would have been available to watch UPC DVB-C on the Dreambox I would perhaps have chosen UPC DVB-C instead of KPN Digitenne DVB-T. Paying for the smart card is fine for me, but I would like to use it in the receiver I like.


    I also would like to watch in Holland Swedish TV (because I have worked in Sweden). I am considering getting myself a Swedish ViaSat smart card which I will register at the address of a former Swedish colleague. ViaSat connects their smart cards to the serial number of their receivers, so a Dreambox with a NDS CI modules does not work. If I want to use my Dreambox I need ....... (which I am not allowed to discus here). Again, paying for the smart card is fine for me, but I would like to use it in the receiver I like.

    Not everybody is as lucky as you are:
    1. There are people having (too) small dishes like the Digyenne. (in Holland bigger dishes give bigger problems with real estate owners and city counsels that try to ban satellite dishes);
    2. There are people watching satellites over the edge of the coverage area of that satellite;
    3. There are people having dishes high up on a roof, which are dependant on others to point them (vertigo, phisically not capable of standing on ladders, etc.);
    4. There are people with poor DVB-T coverage;
    5. There are people with a poor DVB-C signal (not all cable companies deliver the quality one would expect from them);
    6. Etc., etc., etc.


    An important quality of any receiver is how well it can cope with less then perfect input signals. Of cause it is fair not to complain about short interruptions in the reception if one has a poor signal. But one shall complain if the Dreambox crashes, that is fully uncacceptable.

    You can download from my website an MPEG file made of the RF output of my Dreambox (using a DVD recorder). See http://www.fwiarda.com/etc/dreambox/crash.mpg .


    Travel Ch +1 is an FTA DVB-S channel.
    Travel Ch is an FTA DVB-S channel.
    Tele2/Voetbal 1 is an encrypted DVB-T channel.
    Canvas/Ketnet is an encrypted DVB-T channel.
    Een is an encrypted DVB-T channel.


    I am using the official Dreambox rel.2.2 image from 26-3-2007. I use a Conax CI module with a KPN Digitenne smartcard. Normally I have disabled the official Dreambox dccam in /etc/init.d/bootup, to avoid crashes. For this experiment I have re-enabled it.


    As you see it is realy a matter of minutes before I get a crash. When zapping around the crash usually comes sooner. However, if one has some more patience one gets the crash as well when staying tuned to one channel.


    It is not a total crash, since one can still zap around. However, none of the channels will give any picture.


    I have a strong feeling that it has something to do with the entitlement control messages getting corrupted and doing something strange with the CAM.

    I have installed a recente build from CVS (see http://www.boxman-images.de/board/thread.php?threadid=1026 ). The problem is still there but it is less dominant.


    My DVB-T reception is on the edge. With the official Dreambox image from 26-3-2007 it typically took a minute or so before the Dreambox would hang. With the new image it takes about an hour. A big improvement!


    Actually my DVB-T reception is so poor that it anyhow does not make much fun watching it. (I still have analog cable as backup until a new DVB-T transmitter is placed in my city.)


    Regards, Frits

    Danke sehr!


    My DreamBox fails to boot up with this new xilleon.ko . The bar in the LCD display freezes at about 2/3. That is about where the modeprop xilleon command is in the /etc/init.d/bootup .


    I suspect we need to update some library files as well for this updated module to work.


    Regards, Frits

    And here the md5sums for the DMM image release 2.2 from 26.03.2007.



    The xilleon.ko is different. Dcdead, can you post your xilleon.ko as attachement? I will try if replacing it solves anything.

    Attached an enigma2 log after the bug appeared. I killed enigma2 and restarted it. Probably pretty rough what I did, but I now no better way to force a log. If one starts enigma2 from the command prompt it prints it's logging messages to stdout. I did cut and paste this output into the attached file.


    After I lossed the picture, I logged in with telnet and did enter:
    killall -9 enigma2
    enigma2


    Restarting enigma2 this way did not bring the picture back. A full reboot was needed for that.

    I have a DreamBox 7025 with DVB-S + DVB-T. I use the official firmware release 2.2 from 26.03.2007, which I downloaded from Dream Multimedia's web site. I have the problem in combination with the official Dream Multimedia CAM (dccam). Disabling the CAM has solved this problem, but makes it of cause impossible to watch the channels which need the CAM.


    I do have the problem with DVB-T as well as with DVB-S. I have very poor DVB-T coverage in my city, so it is very easy to reproduce the problem. To reproduce the problem with DVB-S, I have to put a wet handkerchief over the LNB. Then it is easy reproducible as well.


    I would suggest to the Dream Multimedia developers to put an adjustable attenuator in the coax cable, and turn the attenuator up to the reception threshold. The problem will show-up within a minute or so.


    It would be very welcome if people from Dream Multimedia would react to this thread. I am sure they are reading it because they did edit one of my earlier posts in which I mentioned which hacker soft CAM has the same problem as the original Dreambox soft CAM. So please moderator tell us what the status is!


    Can other users specify which software versions they are using?


    Regards, Frits

    No, the original DreamBox soft CAM is not illegal. One even needs this soft CAM to use the free 9 months subscribtion on the terrible boring INXTC TV for which a smart card is included when one buys a DreamBox.


    Only watching pay TV channels without smart card using hacker soft CAMs is illegal.


    I think Dream Multi Media shall either solve this bug, or remove their soft CAM and stop shipping the DreamBoxes with the 9 months INXTC TV subscription.


    Regards, Frits

    I have been experimenting further with this problem, and it looks like I have been able to isolate the problem. It is a bug in the soft CAM or soft CAM related code.


    The bug is present in the original DreamBox soft CAM as well as in hacker software that we are not allowed to discus according to the board rules.


    It is irrelevant if a smart card is inserted or not. If the soft CAM is running and one zaps to an encrypted channel with poor reception the DreamBox 7025 will hang.


    I commented the following line out with a # in the file /etc/init.d/bootup:
    # /usr/bin/wdog /usr/bin/dccamd -
    This disables the original DreamBox soft CAM and seemed to solve the problem.


    I now use a Conax CI module to view the Dutch Digitenne DVB-T pay channels. (Due to a temporary switch off of the repeater in my city Arnhem the reception is currently very poor, which resulted in my DM7025 to hang continuously.) Besides the DVB-T pay channels I watch free-to-air satellite channels.


    Can other users confirm?
