Hi,
this may be perfectly normal, but I thought it was a bit odd... I'm receiving DVB-T from the Malvern transmitter, and the frequencies I tune in to correspond to the ones listed on the OfCom web site:
http://www.ofcom.org.uk/static/reception_advice/digital_trans_guide/sho w_tr ansmitter.asp-siteID=49.html
but when I run "scan" from the linux-dvb-apps-1.1.0 tar ball - giving it "T 722166667 8MHz 3/4 3/4 QAM16 2k 1/32 NONE" as a starting point, it gives the Network Name as Sutton Coldfield. Also, even if I leave scan running for about an hour it keeps trying to tune into a bunch of non-existant frequencies (aswell as 5 of the 6 on the Malvern transmitter) and never tries to tune to the last Malvern frequency (718MHz) - so it never ends...
got any ideas?
Several of the UK transmitters I know of are misconfigured... it looks like they've forgotten to update the NIT tables giving the frequencies. e.g. Angus and Craigkelly had bad NIT tables when I was testing them last year (although they may have been fixed by now).
If you think that's bad, you should see the tables on Hotbird. Sheesh. Certainly good if you want to bulletproof your table parsing code :)
Well, if dvbscan goes into an endless loop it is a bug (probably already fixed in CVS).
Its not necessarily a bug in dvbscan; there is a transmitter on hotbird which has buggy NIT tables; it says there are two table sections when in fact there is only one.
it's not a bug in dvbscan, it keeps looping because it never manages to tune in to the frequencies that the Malvern transmitter isnt broadcasting on - so if the Malvern NIT was correct those extra frequencies wouldnt be listed and 718MHz would be added
I vaguely remember someone refering to the Malvern transmitter as being a "repeater" - is it just rebroadcasting what it gets from Sutton Coldfield? (this was a few years back, and I don't really know much about hardware... ;-)
