Re: [Discuss-gnuradio] [GSoC 17] DAB: Updates

Hi, As you may know, we've developed gr-isdbt a couple of years ago now. We are still maintaining it, and I'm happy to announce that we've finally found time to start working on the transmitter. My expectation is that we'll have something usable by the end of this year, beginning next. best Federic

Re: [Discuss-gnuradio] [GSoC 17] DAB: Updates

Hi Marcus, Concerning DRM here in Brazil, there is not much activity because of the immense delay from the government to adopt any standard. Me and a bunch of hams are carrying some trials with DRM in HF, but just this (from Parque do Rodeador, an EBC facility). But DRM signals are always on... in

Re: [Discuss-gnuradio] [GSoC 17] DAB: Updates

Hi Rafael, I don't really see how these are a real problem – if you'd need another encoder, just drop one in – shouldn't be that hard to code if you know which encoder you'll want to use. Of course, you'd need to adjust some bit flags in the flow – but that shouldn't be that hard. So, it's kin

Re: [Discuss-gnuradio] [GSoC 17] DAB: Updates

gr-drm is working fine, but there are some limitations (one audio service only - MDI input support would fix this, only faac AAC LC encoder, ...), and as far as I know, there are no open source ISDB-T transmitter implementation. GSoC always help. Rafael Diniz On 08/18/2017 11:03 AM, Martin Braun

Re: [Discuss-gnuradio] [GSoC 17] DAB: Updates

I wonder when we'll have a DRM app like this one. At least the mux and codec part are very similar could be shared with DAB. May be next GSoC? DRM and ISDB-T are the major wishes here from Brazil. ; ) Regards, Rafael Diniz On 08/18/2017 10:01 AM, Moritz Luca Schmid wrote: > Hi, > > "A DAB/DAB+ t
