    ukchan: How to ....

    We are trying to set a TIVO-community in Denmark with some ( actually a lot!!) of help from a Dutch guy ( Dennis van Onselen). At the moment we are 8 members with 4 us – and 2 uk-tivos – 2 more Thomson’s on the way.

    The Thomson tivos is giving us some problems – the channel provider is altering the frequency of the channels from time to time. Until now we have had some great help from your community on building the ukchan-file – but we can not keep pestering other people with our problem - Is there any way we can chance the frequency of a channel on a Thomson tivo like it is possible on a us-tivo in palmod.?

    If not - we have learn to make and compile the ukchan.o.- file our self. Any link to information on this is appreciated – as will any other info that can help us.

    Sincerely
    joergen

    It is possible, although I like keeping code (particularly kernel modules) as small as possible so prefer to hardcode it

    Okay... I have attached the code for the ukchan module and have uploaded a cut-down (minimal) gcc compiler for the UK Tivo here

    You just need to extract both these into a directory on your Tivo and then you will be able to compile the module yourself. Should be able to do something like the following:
    Code:
    # mkdir /var/hack/UKChan
    # cd /var/hack/UKChan
    # unzip /tmp/ukchan-2.5.5_dk-nicam.zip
    # tar xvfz /tmp/ukchan-gcc.tgz
    
    <edit the ukchan code>
    
    # ./bin/make

    Frequency problem in ukchan30

    Every ting is going great, I am compiling like a professional – at lest I was until a friend of mine wanted to chance the software on his UK-thomson from ver. 2.5.5 to ver. 3.0.

    At first I tried to use the ukchan-2.5.5. File on ver. 3,0 – but that just made TIVO go into a constant reboot. Then I tried the ukchan30 from Oztivo – it worked – in mono – but it worked – except from one ting: I can not get my channel 3 to work on 502250 HZ. It seems as if there is some limits to what frequency the differed channels can use – if I move 520250 to channel 5 it is working OK – unfortunately that would give us some trouble with setting up the emulator, TIVO and tv – I have the same problemwith channel 16 - is there a way around this ?

    I have been working with this problem for the last 8 – 10 days and I stock now – any ideas is welcome – and an other ting - is there a nicam-version of ukchan30 out there ?

    I do not see any reason to use v3.0 over v2.5.5... There are a few things that v3.0 does that are not ideal (such as rename manual recordings). In my opinion v2.5.5 is by far the better choice (particularly for the UK Thomson).

    Sorry I can't really help with this one... I do not know of any restrictions that would cause problems. I am sure that this can be got to work, but I would still suggest sticking with the v2.5.5 image (it is more reliable than the v3.0 software). I have the latest packages up and running on this version without any issues: AutoSpace, Links, SliceUtils, Tpip, EndPadPlus, Logos, SlideShow, TyServer, FanControl, MFS_FTP, TCS, UKChan, BufferHack, Games , TCTimeOut, CheckSchedule, MonitorIP, Teletext, Compiler, HDefRec, NewText2OSD, TivoFTPd, ZX81, Cron, Html2Txt, NoFlicker, TivoPOP, DNS, IIC, TivoTitle, DST, IRTools, DailyMail, InetUtils, ScreenSaver, TivoWeb, EditTitle, JPEGwriter, TivoWebPlus. I am more than happy to upload any or all of these if you are having trouble getting something working - in addition to this, if you are having trouble with a particular package then I am happy to have a shot at getting it working.

    Change the following line (at the bottom of getFreq_x):
    iicw4(0x88, 0x10, 0x00200003); /* B/G Dual FM Stereo */
    to read:
    iicw4(0x88, 0x10, 0x00200008); /* PAL B/G NICAM Stereo */

    Hi Thomson
    It seems as the problem is related to the frequency table – if I change the frequency in f = (freq-471250)*1000 + 510150000; to the Danish start frequency for the UHF area ( 470250 ) channel 3 is working - but then 5 and 6 is not.

    Not knowing how the setup around the frequency table is working – I convinced my friend to take your advice and go back to ver. 2.5.5 - Thank you so must – again

    Sorry about my English – but I gees it better than your Danish -:)

    Actually... it looks like the maths in the ukchan30 module could be wrong... you probably want to replace it with the following section of code:
    Code:
    *p1 = (freq-471250)*1000 + 510150000;
    
    if (freq >= 431250) {         // UHF
      *p2 = 2;
    } else if (freq >= 147250) {  // VHF-Hi
      *p2 = 1;
    } else {                      // VHF-Lo
      *p2 = 0;
    }
    
    iicw4(0x88, 0x10, 0x00200008); /* PAL B/G NICAM Stereo */

    I really do feel the v2.5.5 software is a better option. I do not know of a feature introduced in v3.0 that would make running it worthwhile... and yes, my Dutch is very limited

    – now you are making me curious.

    Just for the fun of it - I will give it a try next month when I am having some days of from work. Will keep you posted -

    compiling ukchan.o - howto w/o nicam?

    Hi, I was looking to compile this for a UK Thomson TiVo located in HK to receive the local channels. They are based on the UK UHF channel set but with an offset (...224 instead of ...250). Actually there are only four FTA channels here - 49, 51, 53 and 55. But I want the sound to stay same as UK, i.e. not Nicam. How would I modify the script before compiling?

    Also, I modified some lib files and when I try to change the ukchan.c file or compile it I get a Segmentation fault error - I'm guessing due to the change in lib files. Any idea if that's what's causing it?

    Thanks!

    Also - I see that TiVo is launching in Canada. With some luck maybe they'll come to HK but I'm not holding my breath.

    Bill

    Can't help you on the UK chan thats Thomsons baby.

    But as for TiVo in Canada & HK, TiVo launched in Canada a couple of years ago providing full guide data, but for some reason did not retail boxes in Canada. The recent announcement is just that TiVo's will now be available for sale at a few big box retailers in Canada.

    As for Hong Kong, it is the supposed to be the next Market TGC (TiVo Greater China) expanded into this year. But there seems to have been lower than anticpated demand for TiVo in there current markets of Taiwan and China, which has slowed or even stopped there expansion.

    Their websites are currently offline (http://www.tgc-usa.com, www.tgc-china.com.cn), which doesn't bode well for the planned HK & Singapore expansion.

    Peter.
