== What is it? ==

DVBlast is a streaming solution to stream multiple channels of TV to a network. A DVB-Card (terrestrial, cable, satellite) or an ASI-Input-Card from [http://www.computermodules.com/ Computer Modules] is needed to provide input to DVBlast. Thanks to videocompression and ''some magic'' one frequency (so called "transponder" can hold multiple TV-channels. So if your DVB-device is tuned to one frequecy, the whole so called "bouquet" could be used by applications like DVBlast. More information can be found on [http://www.videolan.org/projects/dvblast.html videolan.org server].


== Get it ==
First place to get it: [http://www.videolan.org/projects/dvblast.html videolan.org server]. You have to compile it from source and you will need to install libdvbpsi in order to make it work.
You could also use your package manager. On Ubuntu-based systems you could use ''sudo apt-get install dvblast'' for example.


== Using it ==
First of all you have to know how channels and bouquets are organized it your DVB-source. A could thing to start with is wscan, which could output you a channels.conf, including a list of frequencies to be tuned to and channels on a frequency´s bouquet.
Easiest way to use it is to create a config file, which could look like this one:

root@streamdev-01:~# cat freeHD.conf

239.255.0.1:1234        1       11100

239.255.0.2:1234        1       11110

239.255.0.3:1234        1       11120



First is the multicast-IP (and :port), which is causing DVBlast to "blast" everything into the whole network. Be aware, that some soho-routers/APs and switches have severe problems with the many packets DVBlast generates and sends. My AVM Fritz!Box is rebooting as long as I have DVBlast running the above config file (which broadcasts three HD-streams simultaneously).
Call "dvblast -c freeHD.conf" in a Kabel Deutschland, Hamburg-based environment for this to work.


More to come, I will extend these explanations.
