Things are moving along – last night I issued PULL requests for the em28xx PAL VBI support, as well as some cleanups for the HVR-1600 ALSA support that Mauro asked for.

I also checked in the patches I referred to last week when doing cx88 testing with tvtime (testing with a PCTV 800i). There is still definitely a problem there with the cx88 VBI implementation that needs to be dug into, but I haven’t had time to do it yet.

I spent several hours over the weekend trying to get my new DVB-T generator working, but it had two different problems in the two machines I tried it in (both relatively new with clean OS builds). I am following up with Dektec technical support, but it’s going slower than I would have liked. I’ve got several different DVB-T related products that are blocked on having the generator, so I am quite motivated to get it working as quickly as possible.
With the holiday upon us, there will likely be a bit of a lull in posts over the next week or so. Family obligations, Christmas shopping, etc.
hi, i don’t know what is your “dvb-t generator” but i can suggest also our OpenCaster open source project for a quick and easy system for DVB stream generation. and it works really well with Dektec gears like DTA110T:

you can create both well formed PSI table and messed up to. it’s useful for DVB testing.
hope it help and regards
Hi Andrea,
Yeah, the generator I picked up actually is the DTA-110T. In this case, the problem is not with the creation of sample MPEG streams, but rather getting the card to work at all (driver issues).
Thanks though,
Devin
you mean driver under linux, i suppose..
we are using debian 32 and they work pretty well for us.
let me tell you that there’s anyway a big fatty user level library for COFDM modulation (IIRC named libdtapi) as the OFDM modulation is computed in user level mainly. (and it’s a fairly heavy process. it takes 40% of a core of our 4 cores intel cpu)
some time ago we asked for a 64bit version but i don’t know if they released it in the meantime as we lost the interest to switch to 64bit kernel. too few testers in the general community! 😉
bye
