Changes between Version 6 and Version 7 of free-video-streaming-technology

30	30	* A USB audio device that can take inputs. This is helpful as most laptops expect microphone input and so do odd things with gain, reducing audio quality. There are many mixers and other simpler devices available. As long as it works on your version of GNU/Linux with ALSA, it can be used as a source. Thinking about the sound is important, as poor sound quality is more distracting than poor video quality.
31		* A VGA converter, such as the TwinPact100 (a model recommended by the DVswitch developers that runs ~$500USD). This will allow you to turn a presenters computer into a video source for the stream.

33	33	The three computers running dvsource, dvswitch and dvsink is an ideal setup. In a pinch all three pieces can be run on fewer machines. We have successfully run all three on an x61 Thinkpad, but the machine ran '''hot'''. Dvsource is very lightweight, and can be run on an old machine with little RAM. DVswitch can be moderately CPU intensive and depending on how many dvsources you are using that scales up. DVsink is processor intensive, mainly because ffmpeg has to convert the dv stream to ogg. If using two machines, it is best to split the sink from the switch.
