Johnathan, It would be nice to include Dream and gr-drm, for DRM support in the next LiveDVD. ; ) Best regards, Rafael Diniz Em seg 11 nov 2013, s 05:31:48, Johnathan Corgan escreveu: > The GNU Radio LiveDVD has been updated: > > http://gnuradio.org/releases/gnuradio/iso/ubuntu-1... gnuradio-2013-1110.torrent

Sadly Dream appears to be an "open source" implementation of a protocol that is licensed and has no rights allowing for a decoder. While you may choose to use it, sadly, distributing it on a livecd would be very unintelligent as it would make the distributor legally liable for breaching the license most likely. Thanks, Zero

Hi Zero, You're wrong. Dream can be distributed as it's GPL licensed. All the code is GPL, except concerning the AAC codec (FAAC and FAAD2), but you don't need to distribute it together with dream, as it dlopen()'s the AAC library dinamically (so you can install AAC "live"). Most windows and linux dream distributions just do not place the AAC together, and recommend you to just install it separatelly (from rarewares or a simple script that downloads the source and compile it). Also, for the purpose of lab testing, modulation/demodulation, I don't even use the AAC codec, as it also comes with the great Opus codec, which is much better than the FAAC AAC LC encoder.

You will notice they say these words, all in red, on a line by themselves: "Although this software is distributed as free software under the terms of the GPL this does not mean that its use is free of rights of others. The use may infringe third party IP and thus may not be legal in some countries." I would strongly discourage anyone from distributing code that is violating someone else's IP. The code is gpl, that's great, but since it is violating (if I had to guess a US patent) IP knowingly, it puts anyone distributing it at risk. I know I for one won't be distributing such code with my livecd which contains GnuRadio. Obviously anyone else can do what they think is best. Amazing what you notice when you read something... -Zero

I'm pretty sure if you look hard enough you'll find some blocks in GR that implement or could implement some patented telecom technique ... The user could also acquire a license on his own (license which btw is free of charge for low qty).

I don't support the "let's keep our eyes closed" approach. Everyone that generates a product or service he intends to sell is (should be) aware of the fact that he has to care about foreign rights (patents, especially) can be involved. The inclusion of such software on a scientific/free live dvd is quite unspectacular, I guess. Unless someone starts selling products bundled with that DVD. But I think everyone involved with selling GR-related product has quite a nice idea of the intellectual property involved in designing signal processing hard- and software. Greetings Marcus
